BİYOLOJİ ÖĞRETMENİ ADAYLARININ SERA ETKİSİ İLE İLGİLİ ALGILAMALARI

Öz

Bu araştırmanın amacı biyoloji öğretmeni adaylarının “sera etkisi” kavramı ile ilgili algılamalarını araştırmaktır. Bu amaçla literatürden yararlanılarak araştırmacı tarafından bir anket geliştirilmiş ve 152 biyoloji öğretmeni adayına uygulanmıştır. Anketlerin uygulanmasından sonra toplam 25 öğrenci ile görüşmeler yapılmıştır. Nicel verilerin analizinde çevre ile ilgili dersleri alan öğrencilerle (4. ve 5. sınıf), almayan öğrencilerin (1., 2. ve 3. sınıf) anket maddelerinin her biri için verdikleri cevapların dağılımları arasında istatistiksel olarak farklılık olup olmadığını belirlemek amacıyla X2 (Kay-kare) testi analizi yapılmıştır. Ayrıca her bir anket maddesi için verilen cevapların nedenleri görüşmelerde yer alan öğrencilere ait veri kesitleri ile açıklanmıştır. Analizler sonucunda öğrencilerin sera etkisi ile ilgili bazı yanlış kavramalarının olduğu tespit edilmiştir. Çevre ile ilgili dersleri alan öğrencilerin bazı anket maddelerinde dersleri almayan öğrencilerden daha fazla bilgiye sahip oldukları fakat çevre dersleri almayan öğrencilerle bazı benzer yanlış kavramalarının olduğu belirlenmiştir.

PRE-SERVICE BIOLOGY TEACHERS’ PERCEPTIONS OF THE GREENHOUSE EFFECT

Öz

The aim of this study was to identify pre-service biology teachers’ perception about the concept of “greenhouse effect”. With the help of the related literature a questionnaire was developed by the researcher. A survey questionnaire and interviews were used to collect the data. After the survey questionnaire administered to the 152 pre-service biology teachers, 25 students were selected to conduct interviews. For the quantitative analysis, in order to compare the students’ responses enrolled courses about environment and the students who were not a X2 (Chi-square) test was used for item-wise analysis of the questionnaire data. For explanation of the causes of students’ responses for questionnaire statements, data segments were used obtained from interviews. The analysis of data reveals that preservice biology teachers possess an array of incorrect ideas about greenhouse effect. However students enrolled to courses on the environment have more clear ideas than students who were not, they also possess some similar misconceptions about greenhouse effect.
