DEVELOPMENT AND APPLICATION OF TWO-TIER MULTIPLE CHOICE INSTRUMENT ON SOME CONCEPTS OF CHEMISTRY

Abstract

The aim of this study is to develop a two-tier multiple-choice instrument about evaporation, evaporation rate and vapor pressure and to investigate its applicability. Firstly, with this aim, in the light of literaure students’ misconceptions were determined relating to these concepts. Later, based on the misconceptions idendified the two-tier multiple-choice diagnostic instrument consisting of 16 items was developed. The test was conducted to a sample of 208 students engaged in chemistry teacher program, matter analysis of the test items was carried out and the misconceptions held by the students were discussed by evaluating their responses to the items.

BAZI KİMYA KAVRAMLARINA YÖNELİK İKİ KADEMELİ ÇOKTAN SEÇMELİ BİR TESTİN GELİŞTİRİLMESİ VE UYGULANMASI

Abstract

Bu çalışmanın amacı, buharlaşma, buhar basıncı ve buharlaşma hızı kavramları ile ilgili iki kademeli çoktan seçmeli bir test geliştirmek ve bu testin uygulanabili rliğini incelemektir. Bu amaca yönelik olarak, öncelikle, ilgili konularda öğrencilerin sahip oldukları kavram yanılgıları literatür ışığında tespit edilmiştir. Daha sonra, tespit edilen kavram yanılgıları dikkate alınarak 16 sorudan oluşan iki kademeli çoktan seçmeli teşhis edici test geliştirilmiştir. Geliştirilen test, kimya öğretmenliği programına kayıtlı 208 kişilik bir öğrenci grubuna uygulanmış, teste ait madde analizi yapılmış, ayrıca öğrencilerin teste verdikleri cevaplar değerlendirilerek sahip oldukları kavram yanılgıları tartışılmıştır.
