KİMYA ÖĞRETMEN ADAYLARININ ATOMLA İLGİLİ BAZI KAVRAMLARI ANLAMA DERECELERİNİN BELİRLENMESİ

Bu çalışmada kimya öğretmen adaylarının, Atomla İlgili Bazı Kavramlara ilişkin kavrama ve bilgilerinin kalıcı olma dereceleri araştırılmıştır. Araştırma, 2004-2005 öğretim yılı güz döneminde G. Ü. Gazi Eğitim Fakültesi Kimya Öğretmenliği Ana Bilim Dalı, birinci, ikinci ve beşinci sınıfta öğrenim gören toplam 97 öğrenci üzerinde gerçekleştirilmiştir. Verilerin toplanması, araştırmacılar tarafından hazırlanan, atomla ilgili, beş bölümde toplanan, 10 adet “açık uçlu” ve 12 adet “doğru- yanlış” olmak üzere toplam 22 soruluk test ile gerçekleştirilmiş; test sonuçlarını değerlendirmede; “Tam anlama”, “Kısmi anlama”, “Belirli yanlış kavramalarla birlikte kısmi anlama”, “Belirli yanlış kavramlara sahip olma” ve “Hiç anlamama” olmak üzere toplam 5 kategoriden oluşan korelasyon tablosu oluşturulmuş; SPSS programı kullanılarak, ANOVA ve t- testi ile değerlendirilmiştir. Sonuçta, öğrencilerin bir kısmının konuyu iyi kavramasına karşılık bazılarının bilgileri anlamlı bir şekilde öğrenemedikleri, zihinlerinde ilişkilendiremedikleri saptanmıştır. Bunların nedenlerini araştırmak amacıyla, testten düşük puan alan beş son sınıf öğrencisiyle mülakat yapılmıştır. Sınıf başarıların karşılaştırılması sonucunda son sınıf öğrencilerinin daha başarılı olduğu saptanmıştır. Ayrıca alt problem olarak, öğrenci başarısına “cinsiyetin”, “ailelerin kültür seviyelerinin” ve “gelir durumlarının” etkisi araştırılmış ve cinsiyetin etkili olmasına karşın, ailelerin kültür seviyeleri ve gelir durumlarının etkili olmadığı saptanmıştır.

DETERMINATION OF THE LEVELS OF PERCEPTION OF SOME OF THE CONCEPTS RELATED ATOM BY THE PRE SERVICE CHEMISTRY TEACHERS

The level of perception of the pre service chemistry teaching students about “Some of the Concepts of Atom” was investigated in this study. There were 97 first, second and fifth year students from Department of Teaching Chemistry of Gazi Faculty of Education in Gazi University in the first semester of 2004-2005 academic year. The data were collected using a conceptual test related with atom consisting of five subjects including 22 questions with 10 “open ended” and 12 “yes-no” questions. The test results were evaluated the level of perception in five categories as “Full perception”, “Partial perception”, “Partial perception with certain misconceptions”, “Persistence of certain misconceptions” and “No perception” on the correlation table. ANOVA and t-test are used to analyze data by SPPS program. These results showed that some of the students integrate what they learned about topics. But some students cannot integrate their new knowledge with what they learned before. To investigate the reason of such misconceptions of the students, the researchers interviewed five students who took the lowest scores in the test. It is seen that the fifth year prospective teachers are the most successful students when their academic achievement are compared with other students. Furthermore, the effects of the gender of the students, the cultural and economical conditions of their families on their success investigated as a sub problem. It was observed that the income and cultural levels did not have any significant effect on the scores of the students. However, the gender was found to have a significant effect on their success.
