Abstract:

 The aim of this study is to develop a highly valid and reliable achievement test that measures ninth-grade students level of understanding of the topics and concepts covered in the Interactions between Chemical Species unit. Designed using a survey method, this study collected data from 10 experts in chemistry education and 174 high school students, and CVI validity values were calculated according to the Lawshe technique. The CVI value for the second version of the achievement test, from which the opinions of two field experts were obtained and necessary corrections were made, was found to be .95. The pilot application of the test was then conducted with 174 high school students. The data obtained yielded item difficulty index IDI.57, item discrimination index IDI.25 and KR-20.83. After corrections and analyses, the final version of the achievement test, which initially contained 27 questions in the item pool, resulted in a 26-item achievement test. It is assessed that the developed achievement test can be used as an effective tool for determining student achievement within the relevant topic area.

 Bu araştırmanın amacı dokuzuncu sınıf öğrencilerinin Kimyasal türler arası etkileşimler ünitesinde yar alan konu ve kavramları anlama düzeylerini ölçen geçerlik ve güvenilirliği yüksek bir başarı testi geliştirmektir. Tarama yöntemiyle tasarlanan bu çalışma da 10 kimya eğitimi alan uzmanından ve 174 lise öğrencisinden veri toplanmış, Lawshe tekniğine göre KGİ geçerlik değerleri hesaplanmıştır. Alan uzmanlarından iki defa görüş alınan ve gerekli düzeltmelerin yapıldığı başarı testinin ikinci versiyonu için KGİ değeri .95 olarak bulunmuştur. Daha sonra testin pilot uygulaması 174 lise öğrencisi ile gerçekleştirilmiştir. Elde edilen veriler ile MGİ.57, MAİ.25 ve KR-20.83 olarak hesaplanmıştır. Hadde havuzunda başlangıçta 27 sorunun yer aldığı başarı testinin nihai versiyonunda yapılan düzeltme ve analizler sonunda 26 soruluk bir başarı testi elde edilmiştir. Geliştirilen başarı testinin ilgili konu kapsamında öğrenci başarılarını belirlemede etkili bir araç olarak kullanılabileceği değerlendirilmektedir.
