Bu çalışmanın amacı, 8. sınıf “Maddenin Halleri ve Isı” ünitesine yönelik çoktan seçmeli sorulardan oluşan bir akademik başarı testi geliştirmektir. Bu amaç doğrultusunda 28 soruluk bir akademik başarı testi geliştirilerek testten elde edilen puanların geçerlik ve güvenirlikleri incelenmiştir. Testin uygulama aşamasından önce uzman görüşleri doğrultusunda belirtke tablosu oluşturularak maddeler yazılmıştır. Soruların kazanımlara ve bilişsel düzeylere dengeli bir şekilde dağılmasına dikkat edilerek uygulama öncesi kapsam geçerliği sağlanmaya çalışılmıştır. Çalışmanın örneklemi Amasya ili, Taşova ilçesinde öğrenim görmekte olan 140 öğrenciyle oluşturulmuştur. Testin örneklemde yer alan öğrencilere uygulanmasının ardından maddelerin güçlük ve ayırt edicilik indeksleri hesaplanmış ve alt-üst grup soru bazlı öğrenci puanları arasında anlamlı farklılık olup olmadığı Bağımsız Örneklemler t Testi ile incelenmiştir. Ölçüt geçerliliğinin sağlanması açısından benzer bir test ölçüt alınarak iki test arasında korelasyon katsayısı .820 olarak bulunmuştur. Açımlayıcı faktör analiziyle bazı binişik soruların olduğu tespit edilmiştir. Binişik olan üç sorunun testten çıkarılması durumunda testteki soruların dört faktör altında toplandıkları ve binişik madde kalmadığı tespit edilmiştir. Testin Cronbach Alpha katsayısı .914 olarak hesaplanmıştır. Binişik soruların testten çıkarılması durumunda Cronbach Alpha katsayısının .905 olduğu belirlenmiştir. Elde edilen bulgulara göre ve ileriye yönelik bazı öneriler getirilmiştir.
The aim of this study is to develop an academic achievement test consisting of multiple-choice questions for 8th grade States of Matter and Heat" unit. For this purpose, an academic achievement test containing 28 questions was developed and the validity and reliability of the scores obtained from the test were examined. Before applying the test, expert opinions were taken and a table of specifications was prepared and then items were written. Questions are written to be balanced to educational achievements and cognitive levels and thus the scope validity was tried to be provided before the application. The sample of the study was composed of 140 eighth grade students from Tasova, Amasya. Item difficulty and substance discrimination indices were calculated after application of the test to students. The independent samples t test was used to determine whether there was a significant difference between the question-based scores of the students in the lower and upper groups. A similar test was used for the validity of the criterion and the correlation coefficient between the two tests was .820. Exploratory factor analysis revealed that there were some overlapping questions. When the three overlapping questions were excluded from the test, it was determined that the questions in the test were collected under four factors and no overlapping question was found. The Cronbach Alpha coefficient of the test was calculated to be .914. The Cronbach Alpha Coefficient was. 905 if the overlapping questions were removed. According to the findings and some forward-looking suggestions were made.
