A Comparison of Mathematics Learning Approaches of Gifted and Non-Gifted Students *

: In this study, it was aimed to investigate the mathematics learning approaches of gifted students and successful students who were not diagnosed as gifted in terms of variables of giftedness, gender, grade level, parents’ profession and education level. Descriptive research model, which is one of the general survey models, was used in the study. For the 2018-2019 academic years, a total of 239 6th, 7th and 8th grade students, 84 of whom were gifted students and 155 of whom were non-gifted students, participated into the study. Data on gifted students were collected from the Science and Arts Center of a province in the Central Anatolia region, while data on non-gifted students were collected from a secondary school in the same province. Students' mathematics learning approaches were determined by using the “Scale of Mathematics Learning Approaches”. When the findings were examined, a significant differentiation was observed in favor of gifted students in the in-depth learning approach between gifted and non-gifted students. In addition, there is a significant difference in favor of female students in in-depth and strategic learning sub-dimensions among gifted students. When the mathematics learning approaches of gifted and non-gifted students were compared according to grade level, no significant difference was found in the 8th grade level average scores.


Introduction
How learning takes place has always occupied our minds. In fact, this is because we have not been able to solve the entire working mechanism of brain yet. It is a learning process for the individual to perceive the stimuli in the outside world and interpret their perceptions in different ways and turn them into a unique product (Beydoğan, 2007;Von Glasersfeld, 1996). In this learning process, it can be said that learning approaches can take an important place when individual differences are taken into consideration. The concept of learning approaches used for the first time by Marton and Saljo (1976) was used to reveal how individuals understand a reading piece. Learning approach, which is also defined as the interaction between the student and the learning task (Ramsden, 2000), is also expressed as the tendency of the individual when learning a subject (Ekinci, 2009). Learning approach expresses the aim of the student in learning, the process the student passed while learning and how the student organizes learning (Spencer, 2003).
Since learning is a multidimensional concept, it can be thought that the methods affecting learning can be multiple and varied. Knowing one's learning approaches helps teachers find more effective and creative ways of organizing their teaching status (Biggs, 1999;Entwistle, 2000). For this reason, it may be necessary to determine the learning approaches of students in environments where teaching activities are carried out in order for students to learn. For this reason, as Özgür and Tosun (2012) stated, learning approaches are an issue to be taken into consideration and researched. Learning approaches depend on the student's attitude towards the subject and the level of readiness, the teacher's attitude towards the student and the teaching methods used (Sezgin & Ellez, 2002). Learning approaches also differ according to the types such as the content of the curriculum, function, teaching methods and techniques, features of the learning environment, evaluation methods (Ekinci, 2009;Entwistle & Smith, 2002).
Learning approaches are important for an efficient and effective learning (Yıldız, 2015). For that reason, it is important to know how the student learns in order to understand what kind of student he is and to be able to guide him (Oğuz & Karakuş, 2017). Considering that learning approaches affect the academic success of the learner (Öztaşkın, 2014), it is necessary to determine the factors that leads students to researching and questioning in the process of education in other words, that force students to use the superficial or in-depth approach in the educational process (Çolak, 2006). Moreover, when the researches on mathematics education are analyzed, it is seen that the focus is on determining the factors that affect students' mathematics achievement (Pourselami, Erfani & Firoozfar, 2013;Zakaria & Nordin, 2008). It can be said that one of these factors is students' mathematics learning approaches. Because when they know their students' mathematics learning approaches, mathematics teachers will review their own teaching activities and will be able to make effective instruction by guiding students towards them (Göktepe- Yıldız & Özdemir, 2008). When we consider the learning approach as the student's way of processing information, the ways in which students deal with learning can be categorized into three groups as superficial learning approach, in-depth learning approach, and strategic learning approach (Marton & Saljo, 1976).
In the in-depth learning approach; it is essential to understand the source of the information obtained, to know its usage areas and to establish a relationship between them (Darlington, 2011). It was emphasized that the main objectives of the students who preferred the in-depth learning approach were understanding, that the examination of the related components was realized for learning, and that this review was transformed into a harmonious whole through a process (Chan, 2003;Ramsden, 2000). Byrne, Flood and Willis (2009) also stated that individuals with in-depth learning approach will obtain high-level learning products. Curzon (2004) emphasized that with this learning approach, students can test by creating hypotheses and see the connections between the topics.
The approach in which the learning ability is stable, the belief that the information is precise and unchanging is dominant and the information is presented by the authority is called superficial learning approach (Chan, 2003). Biggs (2001) stated that students who prefer superficial learning approach use low level skills even in a learning activity that requires using high level cognitive skills. Superficial learning approach is focused on memorization, no relation is searched between concepts (Biggs, 2001;Trigwell & Prosser, 1991). Byrne, Flood and Willis (2001) stated that students with superficial learning approach have failed to memorize the necessary knowledge to pass exams, tend to focus on individual parts without establishing integrity and distinguish examples from rules.
Students with a strategic learning approach that addresses the issue of learning with the intention of being successful do not intend to search and create meaning (Reid, Duvall & Evans, 2007). Beydoğan (2007) says students who have this learning approach will try to get as high a grade as possible, they will prefer sources that will accelerate their perception by using various materials and in this way, it would be easier for them to learn. Entwistle (1995) stated that the most important feature of the strategic learning approach is that it benefits the organization both in terms of working methods and time management. Some of the studies on learning approaches are as follows: In their study, Beşoluk and Önder (2010) concluded that prospective teachers at undergraduate level prefer superficial learning more often while master degree teachers prefer more in-depth learning approach. In Scouller's (1998) study, where the effect of assessment methods on learning approaches was investigated, it was concluded that students preferred the superficial learning approach when preparing for multiple-choice exams, and that students preferred the in-depth learning approach more in tasks where their higher-level thinking skills were measured. Birenbaum and Feldman (1998) as well, determined that students who adopt in-depth learning approach prefer open-ended questions that are more thought-provoking. For example, in a study specific to a field Lee, Johanson and Tsai (2008) conducted a study with high school students, they examined science learning approaches and determined that students with a constructivist approach to learning, had in-depth science learning approaches. Sezgin-Selçuk, Çalişkan and Erol (2007) aimed to determine the learning approaches of prospective physics teachers and to examine these learning approaches with variables such as gender, grade level, and academic success. As a result, it was determined that the prospective physics teacher candidates preferred the in-depth learning approach more than the superficial learning approach. Özkan and Sezgin-Selçuk (2014) aimed to determine the learning approaches that high school students adopt while learning the physics lesson. In conclusion, it was determined that students preferred in-depth and superficial learning approaches slightly above the middle level in the physics course and that learning approaches did not differ significantly according to their gender. Alemdağ (2015) also examined learning approaches according to some variables in his study with physical education teacher candidates. As a result of his research, he found significant differences in adopting the in-depth learning approach in terms of grade level. He also determined that there is a positive relationship between academic success and learning approach. Cano (2007), on the other hand, reached the conclusion that the students who showed an in-depth approach in their study with high school students had higher academic success. When the studies on primary school students are examined, for example in their studies aiming to determine the approaches of primary school students to learn science lesson; Çoban and Ergin (2008) determined that the superficial and in-depth learning approaches of the students were very close to each other and did not differ significantly in terms of gender. Belge-Can and Boz (2012) examined the relationship between primary school students' preferred learning approaches with gender and age. As a result of their research, it was seen that as the ages of the students increased, their level of adoption of the in-depth learning approach decreased, whereas in all grade levels, more in-depth learning approach was adopted. In addition, it was found that female students preferred the in-depth learning approach more than male students.
Regarding the determination of mathematics learning approaches, Chiu (2012) gathered his understanding of mathematics learning in five categories as constructivist, interpretive, objectivist, protecting the rights and interests of the nation and the utilitarian in his research with 5 th grade students. Matic, Matic and Katalenic (2013) determined that students of engineering faculties prefer strategic, in-depth and superficial learning approaches respectively in mathematics lessons. Darlington (2011) determined that students adopt the strategic learning approach more in their research on mathematics learning approaches with university students. İlhan, Çetin and Kılıç (2013) aimed to develop the scale of mathematics learning approaches in their studies with high school students and two factors such as deep and superficial learning approach were identified in this process. In his study, Göktepe-Yıldız (2019) examined the effect of design-based mathematics applications on the spatial abilities and 3-dimensional geometric thinking skills of 8 th grade students in determined dimensions. In addition, the researcher developed a measurement tool that measures learning approaches in mathematics lesson. As a result of the research, he determined that the students' spatial abilities differ significantly according to their mathematics learning approaches.
Although studies have increased in recent years, there are fewer studies in our country. (Belge-Can & Boz, 2012;Beşoluk & Önder, 2010;Çoban & Ergin, 2008;Göktepe-Yıldız, 2019;İlhan, Çetin & Kılıç, 2013;Sezgin-Selçuk et. al., 2007). On the other hand, it is also stated that instead of examining the learning approaches in general, examining them specific to a field may provide more detailed information (Enwistle, 1997). As a result, as İlhan et al., (2013) stated, the evaluation of mathematics learning approaches by separating them from learning approaches in other fields leads to more appropriate determinations. However, when we look at the studies mentioned above on learning approaches, it is seen that the current studies are oriented towards different education levels and different courses, but studies specific to mathematics are few (Chiu, 2012;Darlington, 2011;Göktepe-Yıldız, 2019;İlhan, Çetin & Kılıç, 2013;Matic, Matic & Katalenic, 2013). As can be seen, even though the math learning approaches have been examined, no research has been found comparing the mathematics learning approaches of students who have been diagnosed as gifted and those who have not been diagnosed as gifted.
It is stated that school programs do not meet the educational needs of students who have been diagnosed with giftedness, and that programs should have versatile and creative features. (Baykoç, 2014;Kontaş, 2010;Palancı, 2004). Students who have not been diagnosed as gifted may have more thoughts that mathematics can be incomprehensible, abstract, difficult and complex than gifted students. Because gifted students are more successful in challenging and complex tasks that require mental performance. (Stuart & Beste, 2011). The features of gifted students enable them to learn more successfully and faster than students who have not been diagnosed as gifted (Ataman, 2004;Davis & Rimm, 2004). Actually, with the determination of this kind of research, the necessary arrangements can be determined by preparing the necessary learning environments and in this way, desired successes can be achieved for both groups. Accordingly, it can be said that the comparison of these two groups can yield important results for the mathematics teaching processes of both groups. Likewise, when the studies conducted are examined, it can be seen that the students with and without a gifted diagnosis are compared through various variables. For example, Mills (1993) researched the personality and learning styles of gifted students in the field of mathematics and determined that there are personal differences between gifted students and those who are not diagnosed as gifted students. Yıldız, Baltacı, Kurak, and Güven (2012) compared the two groups in terms of using problem solving strategies and made suggestions to guide the education of gifted students by revealing that gifted students used more strategies. In their research, Altun and Yazıcı (2010) revealed that there were differences in the learning styles of both groups by using Dunn's learning styles inventory. Also, Arseven and Yeşiltaş (2016) determined that the learning styles of the two groups differed and that gifted students prefer the most "independent" and "competitive" learning styles, while students not diagnosed as gifted prefer the most "dependent" and "participant" learning styles. In this study, both groups attending secondary school will be compared in terms of math learning approaches. By determining the learning approaches in mathematics of a part of a population that makes up a small part of the population, both the picture of the current situation in gifted students will be taken and by making comparisons with students who are not diagnosed as gifted, there will be an opportunity to make some moves in the education of gifted students and students who have not been diagnosed as gifted.
The concept of giftedness is defined as people who perform at a high level compared to their peers in intelligence, leadership capacity or special academic fields (Horn, 2002;Ravenna, 2008;Renzulli, 1999). Therefore, the presence of future leaders, scientists and artists is directly proportional to the importance attached to the education of gifted students (Sisk, 1990). Therefore, early recognition of gifted individuals and development of their skills are two important issues. (Çapan, 2010). Renzulli and Reis (1985) stated that gifted children may need extensive educational opportunities that cannot be provided through normal programs. To meet this need, Science and Art Centers (BİLSEM), which was founded in our country in 1995, care about their differences, add aesthetics to scientific thoughts and behaviors, tries to ensure that students produce, solve problems and self-realize themselves (Bilsem Yönergesi, 2007). Sowell, Zeigler, Bergwell and Cartwright (1990) used the phrase "gifted in mathematics" to students who can demonstrate mathematical skills that older students can do. Holton and Gaffney (1994) stated that gifted students can think analytically, deductively or inductively while solving their math problems. It is obvious that the mathematics education given to gifted students is very important in revealing their such thinking processes. It can be said that thanks to the Science and Art Centers (BİLSEM) in our country, mathematics education of gifted students is given importance. The studies conducted with Science and Art Centers in our country were mostly based on different variables such as problem solving and metacognition (Aktepe & Aktepe, 2009;Baltaci, Yildiz & Güven, 2014;Boran & Aslaner, 2008;Yildiz, Baltaci, Kurak & Güven, 2012;Aytekin, Baltacı, & Yıldız, 2017).
In this study, because it is aimed to compare the emerging situations in the study of mathematics learning approaches of gifted and non-gifted students, the research is thought to provide useful information to all relevant stakeholders and our education system. In this study, it was aimed to investigate the mathematics learning approaches of gifted students and successful students who were not diagnosed as gifted in terms of variables of giftedness, gender, grade level, parents' profession and education level. On the other hand, the findings obtained at the end of the research will be an opportunity to compare with the results of the studies on mathematics learning approaches. For this reason, the problem of the research is determined as "How did the successful students' mathematics learning approaches differ according to some variables whether they are diagnosed as gifted or not". Because, many variables such as age, gender, past experiences, class level, and success level affect the learning approaches (Göktepe- Yıldız & Özdemir, 2018;Senemoğlu, 2011;Trigwell & Prosser, 1991). For this reason, the research problem has been examined in detail according to the following variables too.
Within this scope, the sub-problems of the research are as follows: 1. What are the math learning approaches of students with and without a diagnosis of gifted students? 2. Is there a statistical difference in mathematics learning approaches according to the diagnosis of giftedness among students? 3. Is there a statistically significant difference in mathematics learning approaches of gifted and non-gifted students according to gender? 4. Is there a statistically significant difference in mathematics learning approaches of gifted and non-gifted students according to their grade levels? 5. Is there a statistically significant difference in mathematics learning approaches of gifted and non-gifted students according to the parent's profession? 6. Is there a statistically significant difference in mathematics learning approaches of gifted and non-gifted students according to the education level of parents?

Method
In this chapter; information about the model of the research, participants, data collection, research process and analysis are given.

Model of Research
In this study, descriptive research model was used because it was aimed to reach general evaluations by making comparisons about mathematics learning approaches of gifted students and those students who were not diagnosed as gifted. Descriptive research aims to describe an existing situation as it is without any experimental process (Karasar, 2006). In this study, causal comparison approach was also used, since the research problem was examined separately in terms of variables such as gender, grade level, parent occupation, and education level. Cohen and Manion (1994) stated in causal comparison studies that there will be at least two groups affected by the same situation in different ways, or two groups that are affected and not affected by the assumed situation and that these groups can be analyzed in terms of some variables in order to determine the possible causes and influences of the current situation. Investigations to determine the causes of an existing /naturally occurring situation or event and the variables that affect them or the consequences of an effect are causal comparison studies. (Büyüköztürk, Çakmak, Akgün, Karadeniz & Demirel, 2008).

Participants
A total of 239 students, 84 of whom are gifted students, 155 students who have not been diagnosed as gifted attending the 6 th , 7 th and 8 th grades participated in the study in the 2018-2019 academic year. Data on gifted students were collected from the Science and Arts Center of a province in the Central Anatolia region, and data on students with no gifted diagnoses were collected from a secondary school in the same province. In terms of academic success, the closest school to students in BİLSEM were tried to be chosen. The reason for choosing students close to each other as academic success is to determine whether the diagnosis of giftedness among successful students will make a difference on learning approaches. While choosing a school, all public schools in the province where the research was conducted were ranked according to the average of placement in high schools and the most successful school was chosen. Thus, the criterion sampling was one of the sampling methods for the selection of the public school. Here, school success was taken as a criterion. As seen in the demographic characteristics of the students in Table 1 regarding gender, grade level and giftedness, 133 female (55.6%) and 106 (44.4%) male students participated in the study. 47 (55.9%) of the students who are diagnosed as gifted are girls and 37 (44.1%) are boys. The distribution of these students by grade level is as; 38 (45.24%) students in the 6 th grade, 24 (28.57%) students in the 7 th grade and 22 (26.19%) students in the 8 th grade. It is understood that 55.4% of the students who are not diagnosed with gifted are girls and 44.6% are boys. Considering the distribution by grade level; There are 68 (43.87%) students from the 6 th grade, 56 (36.13%) from the 7 th grade and 31 (20%) students from the 8 th grade.

Data Collection Tools
There are two remarkable studies (Göktepe-Yıldız, 2019; İlhan et al., 2013) that are aimed at determining learning approaches specifically for mathematics lesson. The scale developed by İlhan et al., (2013) has a twofactor structure in the form of a superficial and in-depth learning approach. Therefore, the scale of Göktepe-Yıldız (2019), which is suitable for middle school students, is used to measure all three factors in the form of a superficial, in-depth and strategic learning approach.
The Mathematics Learning Approach Scale developed by Göktepe-Yıldız (2019) consists of 33 items and three sub-dimensions as in-depth learning, superficial learning and strategic learning. The scores derived from the sub-dimensions of the scale are interpreted independently.
The high scores obtained from the sub-dimensions indicate that students tend to prefer that dimension in mathematics lesson more; low scores show that students tend to prefer that dimension in mathematics lessons less. For example, a student's "in-depth learning approach" is high while "strategic learning approach" may be low.
The scale is a 5-point Likert type scale as "I strongly disagree = 1" and "I strongly agree = 5". The three subfactors explain 41.048% of the whole variance. This rate is acceptable (Scherer vd, 1988). Item factor load values vary between .323 and .713 (Göktepe- Yıldız & Özdemir, 2018). When starting the analysis of this study, the skewness -kurtosis values of whether the data show a normal distribution were examined to decide which statistical tests to do first. Distortion (-,886) and kurtosis (1,414) of the whole test; skew (-,959) and kurtosis (,293) for in-depth subdimension; distortion (-1.085) and kurtosis (,847); for the strategic sub-dimension; superficial subscale, is as the form of skewness (,199) and kurtosis (-,512).
Göktepe-Yıldız (2019) determined the Cronbach Alpha internal consistency coefficient of the whole scale as .78. Then, the internal consistency coefficient for the in-depth learning approach sub-dimension was .83, .83 for the strategic learning approach, and .78 for the superficial learning approach. In this study, these coefficients were recalculated and the Cronbach Alpha reliability coefficient of the whole scale was found as .88. In the subdimensions, this number was found to be .89 for the in-depth learning approach and .90 for the strategic learning approach and .77 for the superficial learning approach. It can be said that this scale is sufficiently reliable since scales with a reliability coefficient of .70 and above are considered reliable (Fraenkel, Wallend & Hyun, 2012).

Data Analysis
The researchers went to the chosen middle school located in BİLSEM and the city center and explained the research to the institution administrators and the scale forms were applied to the students with the support of the institution administrators. Scale forms taken from students are systematically numbered and kept for analysis. The data of the research were analyzed by using SPSS 23.00 package program.

Results
In this section, mathematics learning approaches of students who are not diagnosed with gifted students and gifted students are reported for the overall scale according to the gifted students' grade levels, gender, parents' education level and parents' profession.

Results Related to the First Sub-Problem
Descriptive statistics of students' mathematics learning approaches are given in Table 2. Descriptive statistics about mathematics learning approaches of students with and without a diagnosis of giftedness are given in Table 2 below: Since there are 11 items in each sub-dimension of the scale used, the minimum score that can be obtained for the sub-dimensions is 11 and the maximum score is 55. Accordingly, the middle score value was calculated as 33. In the findings related to which learning approach students prefer, the average scores for gifted individuals are listed as in-depth learning approach, strategic learning approach and superficial learning approach respectively. The in-depth and strategic learning approach score averages of the students in this group are above average. The superficial learning approach score average is approximately medium score. In line with these findings, it can be said that gifted students prefer in-depth and strategic learning approaches above the middle level and the superficial learning approach at the intermediate level. On the other hand, the average score of students with no gifted diagnoses from high to low respectively is as strategic learning approach, in-depth learning approach and superficial learning approach. As seen in Table 2, students who have not been diagnosed with gifted skills preferred the strategic and in-depth learning approach above the middle score, whereas they preferred the surface learning approach just below the medium score.

Results Related to the Second Sub-Problem
In order to examine whether there is a statistically significant difference between the mathematics learning approaches of the 84 gifted students who were diagnosed and 155 gifted students who participated in the study, the normality test was performed and because it showed a normal distribution t-test was utilized and shown in Table 3. As a result of the analysis conducted to determine whether students' mathematics learning approaches differ according to the diagnosis of giftedness, a meaningful differentiation was observed in favor of gifted students in the in-depth learning approach between gifted and typical students (t = -2,99, p <.05). In other words, gifted students prefer learning more in-depth approach than other students while learning mathematics. There was no significant difference between the mean scores in strategic learning (t = -,96, p>.05) and superficial learning approaches (t = -1.46, p> .05).

Results Related to the Third Sub-Problem
Independent samples t-test was performed according to the normality test result to determine the difference in mathematics learning approaches of the students who were diagnosed and gifted according to gender, and the results are presented in Table 4. As a requirement of the scale used, analysis was made for each 3 sub-dimensions. When the results in Table  4 are analyzed, there is a significant difference between gifted students according to gender variable in their subdimensions (t = 2.40, p <.05) and strategic learning (t = 3.16, p <.05). This difference is in favor of female students. In other words; gifted female students prefer more in-depth and strategic learning approaches than male students. In the superficial learning approach, there is no significant difference by gender. (t =,01, p >.05). Considering the analysis results of students who have not been diagnosed as gifted students, the mean scores of girls' in-depth and strategic learning approaches are higher than boys, and they are lower in superficial learning approaches. As a result of the analysis conducted to investigate whether this difference in scores was statistically significant among students, it was determined that the scores of female students were significantly higher than the boys only in the strategic learning approach (t = 2,12, p< .05). The difference in scores between girls and boys does not show a significant difference in in-depth and superficial learning.

Results Related to the Fourth Sub-Problem
According to the grade levels, normality test was performed for the analysis of whether mathematics learning approaches of students who were diagnosed and not diagnosed had changed and since it shows normal distribution, independent samples are analyzed with t test and presented in Table 5. In distribution of students according to grade level, there are 38 gifted and 68 normal students in the 6 th grade, 24 superior and 56 normal students in the 7 th grade, 22 superior and 31 normal students in the 8 th grade. When the t-test results of independent samples conducted to compare the math learning approaches of students who were diagnosed with giftedness and not according to grade level were examined, no significant difference was found in mean scores at the 8 th grade level. However, it is seen a significant difference in 7 th grade in-depth learning in favor of gifted students (t = -3,18, p <.05) and in 6 th grade superficial learning approach in favor of gifted students (t = -2,21, p <.05).

Results Related to the Fifth Sub-Problem
The mathematics learning approaches between the two groups were analyzed according to the parents' profession and the results are presented in table below. Table 6 and Table 7 compared the mathematics learning approaches of the students according to the profession of the mothers, Table 8 and Table 9 compared the mathematics learning approaches of the students who were diagnosed with /without giftedness according to the profession of the fathers. With the normal distribution of the groups, how the students' mathematical learning approaches changed according to the mother's profession were analyzed with independent samples t-test and presented in Table 6. Among the gifted students' mothers, the number of public employees is 43 (51.20%) and the number of those who do not work is 34 (40.47%). The number of the mothers of the students who have not been diagnosed with giftedness employed in public sector is 30 (19.35%), and 103 (66.46%) of the unemployed. Looking at the learning approaches of the students according to the mother's professions in Table 6, the in-depth learning approach of the children whose mothers work in public differs statistically in favor of gifted students (t = -3,07, p<.05). In other words, gifted individuals whose mother works in public prefer in-depth learning approaches more than normal students. In the strategic and superficial learning approaches, no significant difference was found among the students.
As a result of the analysis made for the students who are in the category of unemployed mothers, it is seen that there is no significant difference in any learning approach among these students. On the other hand, the averages of gifted students are higher than the other student group in their in-depth and strategic learning approach.
Learning approaches of the students whose mother's profession is "Private Sector" were determined by Mann-Whitney U test. Because 7 (8.33%) mothers of gifted parents and 22 (14.19%) mothers of parents of other groups are in this category and the data are not distributed normally. In this context, the relevant results are as in Table 7.  Table 7 presents data on mathematics learning approaches of students whose mothers are private sector employees. It has been observed that there is no statistical difference between the groups according to the mother's working status in the private sector in gifted and normal students' mathematics learning approaches.
Data on the father's profession are as follows: While the number of fathers of gifted students working in the public sector is 51 (60.71%), the number of those working in the private sector is 30 (35.72%). The situation is as 60 (38.71%) fathers working in the public sector and 80 (51.61%) in the private sector among students with no gifted diagnosis. fathers of students who have not been diagnosed with giftedness is as 60 (38.71%) working in the public sector and 80 (51.61%) in the private sector. Looking at the learning approaches of the students according to the father's professions in Table 8, the in-depth learning approach of the children whose fathers work in the public sector differs statistically in favor of gifted students (t = -2.82, p <.05).
The learning approaches of the students whose father's profession is in the "Not Working" category were also determined by the Mann-Whitney U test. 3 (3.57%) fathers from gifted parents and 15 fathers (9.68) from groups are in this category and the data are not normally distributed. In this context, the relevant results are as in Table  9. As stated in Table 9, there is no significant difference in mathematics learning approaches of students whose father is unemployed.
It can be seen from the 4 analyzes above made according to parents' professions between the two groups that there is a significant difference in favor of gifted among the gifted and normal children whose mothers and fathers work in public sector.

Results Related to the Sixth Sub-Problem
Considering the distribution of education levels of mothers of gifted students, 24 people (28.57%) are high school graduates and lower, 40 (47.62%) are university graduates. Education levels of mothers of students with no gifted diagnoses are 115 (74.19%) high school and lower, 36 of them are (23.22%) university graduates.
In Table 10 and Table 11, the educational status of the mothers from the parents of the students in the two groups were compared.  Table 10 is analyzed, according to the education level of the mothers, the results regarding the mathematics learning approaches of the two groups there is no significant difference observed between the two groups whose mother is in a high school graduate and lower education level. Considering the math learning approach of students whose mothers are university graduates, the scores of gifted students are significantly higher in the superficial learning approach compared to normal students (t = -2,89, p<,05). Although the mean scores in the in-depth and strategic learning approaches are higher in favor of gifted students, this score difference does not create any statistically significant difference.
The learning approaches of the students whose mother's education level is "Post-graduate" are determined by Mann-Whitney U test since the data is not distributed normally and presented in Table 11. This category includes 20 (23.81%) mothers whose kids are gifted students and 4 (2.59%) of the other group. As seen in table 11, comparing the children of mothers at "Post-graduate" level, the in-depth learning approach preference of gifted students is statistically different in favor of gifted to normal students (z = -2,14, p<.05).
Data on the educational status of fathers are presented below. Considering the distribution of education levels of fathers of gifted students, 18 people (21.44%) are high school and lower graduates, while 46 (54.76%) are university graduates. Education levels of fathers of students with no gifted diagnosis were 102 people (65.80%) high school and lower graduates, 45 people (29.03%) university graduates. Independent samples t-test was applied in the analysis of data whose father's education level was high school graduate and lower and university level, as the group data showed normal distribution (Table 12). In Table 12, the results of the analysis of the father's educational status regarding the students 'preferences regarding mathematics learning approaches show that there is no significant difference between the mathematics learning approaches of the students in the two groups in high school graduate and lower graduates fathers' children. In the children of university graduate fathers, the scores in the depth and strategic learning approaches between the two groups did not differ significantly. On the other hand, the scores of gifted students were found to be significantly higher in the superficial learning approach compared to normal students (t = -2.18, p <, 05).
The learning approaches of the students whose father's education level is "Post-graduate" were determined by Mann-Whitney U test since the group data did not show normal distribution and then presented in Table 13. In this category, there are 20 (23.80%) fathers of gifted students and 8 (5.17%) from the other group. When the results of mathematics learning approaches of two groups of students according to father's education level are examined in Table 13, there is no significant difference in mathematics learning approaches of students whose father is at the graduate level.

Discussion and Conclusion
In this study, it has been tried to compare the mathematics learning approaches of students who are diagnosed as gifted and students not diagnosed as gifted. When the results are analyzed, it is determined that gifted students prefer in-depth and strategic learning approaches above the middle level and the superficial learning approach at the intermediate level. In parallel with this result, Renzulli, Rizza and Smith (2002) stated that gifted students have an in-depth learning approach. While students with no diagnosis of giftedness prefer the strategic and in-depth learning approach above the middle level, it is concluded that they prefer the superficial learning approach below the average score. The area in which students who adopt the in-depth learning approach with the increase in the level of success is frequently mentioned in the literature. For example, Bernardo (2003) stated that the frailty in success is related to superficial learning, but high success is related to in-depth and strategic learning approaches. The emergence of an in-depth and strategic learning approach above medium level in both students diagnosed as gifted and not diadnosed as gifted may have resulted from the high academic achievement of the participants. As Davis and Rimm (2004) stated, in order for the in-depth and strategic learning approach to be preferred more, positive environments where students can actively participate in learning processes, emphasize mathematical discussions and proofs through their own knowledge, explore through exploration mathematical concepts and representations, where they can switch these concepts should be created. Therefore, components such as teachers, books, tools in learning environments should be organized accordingly.
In student-centered learning environments instead of teacher-centered learning environments, it is also stated that students with superficial learning approach can change these approaches in the direction of learning in depth (Wilson & Fowler, 2005). In order for students to prefer the in-depth learning approach more in mathematics lessons a student-centered problem-based learning environment (Gordon & Debus, 2002;Sezgin-Selçuk, 2010), an inventive based teaching (Ünal & Ergin, 2006) and an environment with computer-aided materials (Tinker, 1997) need to be created. Therefore, in a classroom where students with a superficial or strategic learning approach are abundant, the teacher can direct their students to in-depth learning with different activities according to the teaching method they choose (Göktepe- Yıldız & Özdemir, 2018). As Biggs and Tang (2007) stated, by creating a better learning environment, more effective answers can be obtained from students, and teaching by presenting inquiry-based problems rather than teaching the information can encourage students to utilize in-depth learning approach. Similarly, Even, Karsenty and Friedlander (2009) also stated that the teacher, who has a very important role in mathematics and has a key role in creating opportunities for bright students to realize their own potential, will have various responsibilities in all these processes. In this study, as mentioned above, due to the fact that there are successful students in both groups, the in-depth learning approach may be overexposed. Therefore, the following suggestion can be given to the teacher, who is the lead responsible for organizing the learning environment, in order to have a positive change in the learning approach. Both students diagnosed with/without giftedness should be allowed to ask questions to their teachers, and great responsibilities fall towards the teachers to let them access information and encourage to thinking.
One of the remarkable results here is that the in-depth learning scores of gifted students are higher than the strategic learning scores; it is the result that students who are not diagnosed with giftedness have higher strategic learning scores than in-depth learning scores. The school chosen within the scope of the research was chosen from the school with the closest students to gifted students as an academic achievement. The preparations and exam successes of the students in this selected school are closely monitored by the school principal and school teachers, and a school atmosphere with an effort to improve the exam performance is provided. Therefore, it may be a consequence of this environment that students studying here prefer to do strategic learning more than indepth learning, which expresses their tendency to learn with exam success and grade anxiety.
There was a significant difference in favor of gifted students in the in-depth learning approach between gifted and normal students. However, no significant difference was found between the mean scores in strategic learning and superficial learning approaches. Similarly, Watkins (2001), Bernardo (2003) and Beyaztaş and Senemoğlu (2015) concluded that there is a positive relationship between academic achievement and in-depth learning so successful students use the in-depth learning approach more. In addition, Beyaztaş (2014) reached the conclusion that the scores of successful students who are in the first hundred in the 4 th grade of Science High School are high. As stated by Offir, Lev and Bezalel (2008), students who learn in depth associate the new information they have learned with their previous knowledge and make inferences from the information they have learned. Likewise, as Darlington (2011) puts it, it is important to understand where the knowledge is obtained considering the in-depth learning approach in mathematics subjects, knowing the usage areas of the subject, and establishing a relationship between them. It is stated in the literature that gifted individuals have the features such as easy and quick learning, loving to learn information in depth and details, showing high concentration and transferring what they have learned to other areas, wondering and analyzing cause and effect relationships, using their time and effort economically (Çitil & Ataman, 2018). Considering these features, it is an expected result that gifted individuals do in-depth and strategic learning from time to time. Because, also in in-depth learning, the individual understands where the knowledge comes from, knows the usage areas, establishes the relationship between them, understands the subject, creates a harmonious whole from the related components, cares about the nature of the information and cares about cause and effect relationships (Byrne, Flood & Willis, 2001;Darlington, 2011;Ramsden, 2000).
There is a meaningful difference in favor of female students in terms of in-depth and strategic learning subdimensions among gifted students. In other words, female students prefer more in-depth and strategic learning approaches than male students. No significant difference in the superficial learning approach by gender was found. In-depth and strategic learning approach is higher in girls with no gifted diagnoses than in boys, and lower in superficial learning approach. As a result of the analysis conducted to investigate whether these scores are statistically significant, it was determined that the scores differ significantly in the strategic learning approach. In line with the results of this research, Smith and Miller (2005) also concluded that male students showed a more superficial learning tendency compared to girls. Many reasons such as excessive self-confidence, fondness in game, computer games and activities, being more relax than girls, and perhaps even spending more time outside in this process may have been effective in the emergence of such a result in students with no gifted diagnosis. On the other hand, when we look at the studies conducted, the results of the study reversed, in other words, that the results for boys to prefer the deeper approach (Severiens & ten Dam, 1997;Watkins, 1996) or that the female students preferred the deeper approach as is also seen in this study (Biggs, 2001). On the other hand, there are studies in which there is no significant difference between gender learning approaches as well (Öner, 2008;Richardson, 1993;Watkins & Mboya, 1997;Tural-Dinçer & Akdeniz, 2008).
Comparing the mathematics learning approaches of the students who were diagnosed with giftedness and not diagnosed as gifted according to the grade level, there was no significant difference in the mean scores at the 8 th grade level. However, it was observed that there was a significant difference in favor of gifted students in the indepth learning approach in the 7 th grade, and in superficial learning approach it was in favor of gifted students in the 6 th grade. In the 6 th grades, although the in-depth learning approach average scores are in favor of gifted students, this difference is not statistically significant. In their study Göktepe- Yıldız and Özdemir (2018), concluded that, as the grade level increases in students who are not diagnosed with giftedness, the tendency of the students to prefer the in-depth learning approach decreases and there is no difference in the students' preferring the superficial learning approach. The situation in this study may have been due to the ability of gifted students to ask more questions in their lessons and their will to reach the information themselves. On the other hand, in some studies with university students, this has been the opposite. (Ozan, Köse & Gündoğdu, 2012;Senemoğlu, 2011). Another remarkable result here is a difference in favor of gifted students in superficial learning in 6 th grades. In the superficial learning approach, it is expected that gifted individuals will not perform superficial learning considering the fact that the information is memorized without the concern of seeking meaning and the information consists of torn pieces in the mind. Although the mean scores are below the medium level in both groups, this difference is thought to be due to constraints of the study group and may be specific to this group. In this study, the in-depth approach mean scores of gifted students decreased as the grade level increased, while the scores of normal students were ranked as 6 th , 8 th , 7 th grade from high to low. Göktepe- Yıldız and Özdemir (2018) stated that, as the grade level increases, the learning environments in schools are expected to make more of the features of the in-depth learning approach work. Again, Göktepe- Yıldız and Özdemir (2018) stated that the decrease in the preference of learning in-depth may be related to the general exam held at the end of the 8th grade. Beyaztaş and Senemoğlu (2015) came to the conclusion that approximately 40% of successful students' families have an impact on their children's adoption of in-depth learning approach due to changes such as setting goals, motivating, organizing and following their work. For this reason, in the research, some examinations were made for parents too as below. In the study, in comparison with the parents' professions between the two groups, there is a significant difference in favor of the gifted among the gifted and normal children whose parents work in the public sector in the in-depth learning approach. Another result is that, When the students' mathematics learning approaches according to the education level of the parents are examined, while no significant differentiation is observed between the two group of students whose mother graduated from high school and lower education levels, a significant differentiation was determined in favor of gifted students in the superficial learning approach between the students whose mother was university graduate. Comparing the children of mothers at post-graduate level, choosing the in-depth learning approach of gifted students has been statistically different in favor of gifted than the normal students. In the case of father education level, it is seen that there is a significant difference in favor of gifted students between the children of university graduates in two groups. It may be due to the mothers of post-graduate education level differentiate the preference of in-depth learning in their children, because as the mother's education level increases, she creates an appropriate learning-teaching environment that will indirectly enable her children to learn, thus motivating her children to learn. For this reason, in order to make the students become more in-depth learners, the efforts to improve the school-family cooperation can be improved so that the parents can take their own responsibility and parents can actively participate in the learning process.
Technology-supported learning environments can be created that will enable students to prefer in-depth learning approaches in mathematics lessons where students are more in center. Again, teachers can plan their lessons by asking problems that will make students think, so that students' learning approaches can be differentiated. In addition, the learning approaches of both groups can be examined in more depth and the underlying causes can be revealed. On the other hand, by encouraging teachers to make collaborative lessons, the richness of the prepared materials that play an active role in learning environments, the variety of asking questions, and the correct pedagogical approaches to their students can be improved. And this situation causes their students to adopt a deeper and more strategic learning style in their learning approach.
