Abstract

The purpose of the study was to develop a valid and reliable instrument to identify 11th gradestudentsʼ readiness for learning the unit of Chemical Reactions and Energy in chemistry course.Firstly, prerequisite subjects and concepts for meaningful learning of the unit were determined in thetest development process. Then, the test items were formed considering the concepts’ significancelevels, and the necessary arrangements were made with expert opinions. Pilot implementation wasadministered to 170 students educated in various high schools in İzmir. In the final version of the testwhich was formed using the results of item analysis, there are 25 multiple choice questions whichhave 5 options. In this study, reliability of the test was found as 0.86 by using KR-­‐‑20 formula.Statistical analyses show that the readiness test developed for Chemical Reactions and Energy unit isvalid and reliable.

Özet

Çalışmanın amacı; 11. sınıf öğrencilerinin, kimya dersi “Kimyasal Reaksiyonlar ve Enerji” ünitesineyönelik hazır bulunuşluklarını belirlemek için geçerli ve güvenilir bir ölçme aracı geliştirmektir. Testigeliştirme sürecinde; öncelikle ünitenin anlamlı öğrenilmesine temel oluşturan kavramlarbelirlenmiştir. Ardından, bu kavramların önem düzeyleri dikkate alınarak test maddelerioluşturulmuş ve uzman görüşleriyle gerekli düzenlemeler yapılmıştır. Pilot uygulama, İzmir ilindebulunan çeşitli liselerde öğrenim gören toplam 170 öğrenci üzerinde gerçekleşmiştir. Madde analizisonucunda son şekli belirlenen testte, 5 seçenekli 25 adet çoktan seçmeli soru yer almaktadır. Testinçalışmadaki KR-­‐‑20 güvenilirlik katsayısı 0,86 olarak hesaplanmıştır. Yapılan istatistiksel analizler,“Kimyasal Reaksiyonlar ve Enerji” ünitesine yönelik geliştirilen Hazır Bulunuşluk Testi’nin geçerli vegüvenilir bir test olduğunu ortaya koymaktadır.
