Pre-service Mathematics Teacher' Opinions about Process of Designing Worksheets with Cabri Software and Their Use in Geometry Teaching

Abstract

In this study, it was aimed to examine the opinions of pre-service mathematics teachers on the process of designing worksheets with the help of Cabri software and the use of these worksheets in geometry teaching. In line with the aim of the study, Cabri Geometry II and Cabri 3D software systems were introduced to pre-service teachers during 12 weeks. The teachers were shown sample worksheets designed by using these software systems and they were asked to prepare worksheets by groups and use them in the classroom environment. Following the training session, the data of the study were collected through face to face semi structured interviews with 41 4th grade pre-service mathematics teachers. The data of the study were analyzed by content analysis method and the codes were collected under six themes. The result showed that most of the participants wanted to design and use worksheets with Cabri software in their future professional life; however, some of the participants were undecided about using these worksheets because of lack of time, crowded classes and lack of equipment. The participants stated that the use of these worksheets has advantages such as concretizing the concepts, discovering, drawing attention, permanent and easy learning. As disadvantages, pre-service teachers stated that it can cause loss of time, the software is difficult to use, that the software is paid, that it is difficult to use in crowded classrooms and that it can cause misconceptions. During the training, it was determined that the pre-service teachers had difficulties due to the lack of technological pedagogical content knowledge and the paid Cabri software. At the end of the training, it was observed that the participants were of the opinion that they showed professional and personal development.

Matematik Öğretmeni Adaylarının Cabri Yazılımıyla Çalışma Yaprakları Tasarlama Süreci ile Bunların Geometri Öğretiminde Kullanılması Üzerine Görüşleri

Öz

Bu çalışmada, ilköğretim matematik öğretmeni adaylarının Cabri yazılımı yardımıyla çalışma yaprakları tasarlama sürecine ve bu çalışma yapraklarının geometri öğretiminde kullanılmasına ilişkin görüşlerinin incelenmesi amaçlanmıştır. Bu amaç doğrultusunda 12 hafta boyunca öğretmen adaylarına Cabri Geometry II ve Cabri 3D yazılımları tanıtılmış daha sonra hep birlikte bazı kazanımlara yönelik örnek çalışma yaprakları tasarlanmış son olarak da öğretmen adaylarından ikişerli gruplar halinde çalışma yaprakları tasarlamaları ve sunmaları istenmiştir. Verilen eğitimin sonrasında araştırmanın verileri, gönüllü olan 41 dördüncü sınıf matematik öğretmeni adayıyla birebir gerçekleştirilen yarı yapılandırılmış görüşmeler yardımıyla toplanmıştır. Elde edilen veriler içerik analizi ile analiz edilerek kodlar altı tema altında toplanmıştır. Araştırmanın sonunda katılımcıların çoğunluğunun ilerideki meslek hayatlarında Cabri yazılımı ile tasarlanan çalışma yapraklarını kullanmak istedikleri, diğer katılımcıların ise zaman sıkıntısı, sınıfların kalabalık olması, donanım eksikliği gibi nedenlerle kararsız kaldıkları görülmüştür. Katılımcılar çalışma yapraklarının kullanımının kavramları somutlaştırma, keşfetme, dikkat çekme, kalıcı ve kolay öğrenme gibi avantajları olduğunu belirtmişlerdir. Dezavantajları olarak ise zaman kaybını, yazılımın kullanılmasının zor olmasını, yazılımın ücretli olmasını, sınıf hakimiyetinin zor olmasını ve kavram yanılgılarına sebep olabileceğini göstermişlerdir. Verilen eğitim sırasında öğretmen adaylarının teknolojik pedagojik alan bilgilerinin eksikliği ve Cabri programının ücretli olması nedeniyle zorluk yaşadıkları belirlenmiştir. Eğitimin sonunda ise katılımcıların mesleki ve kişisel gelişim gösterdikleri görüşünde oldukları görülmüştür.
