Özet:

 The purpose of this study is to describe the development of a two-tier concept test to validly and reliably diagnose 8th grade middle school students misconceptions of pressure issue. The study was conducted according to the two-tier test development procedures. The sample of the research consists of 102 middle school students studying at the 8th grade at a school in Giresun city center. For the validity of the two-tier concept test, opinions of experts were consulted and independent samples t-test analysis was performed. For the reliability of the two-tier concept test, item analysis was performed and KR-20 and Cronbach Alpha values were calculated. In the analysis, the KR-20 value was calculated as 0.85 and the Cronbach alpha value was 0.95. As a result of the item analysis, it was seen that the average discrimination power was 0.53 and the average item difficulty index was 0.59. These values can be interpreted as the developed two-tier concept test being a distinctive and medium difficulty concept test. Within the scope of the study, two-tier concept test consisting of 27 items was developed that can be used to determine the misconceptions of middle school 8th grade students about the concepts in the pressure unit.

 Bu çalışmanın amacı ortaokul 8. sınıf öğrencilerinin basınç konusundaki kavram yanılgılarını geçerli ve güvenilir bir şekilde teşhis etmek için iki aşamalı bir kavram testinin geliştirilme sürecini açıklamaktır. Araştırma iki aşamalı test geliştirme prosedürlerine göre yürütülmüştür. Araştırmanın örneklemini, Giresun il merkezinde bir ortaokulda öğrenim gören 102 ortaokul 8.sınıf öğrencisi oluşturmaktadır. İki aşamalı kavram testinin geçerliği için uzman görüşlerine başvurulmuş ve bağımsız örneklemler t-testi analizi gerçekleştirilmiştir. İki aşamalı kavram testinin güvenirliği için madde analizi yapılarak KR-20 ve Cronbach Alpha değerleri hesaplanmıştır. Analizlerde KR-20 değeri 0,85 ve Cronbach alfa değeri 0,95 olarak hesaplanmıştır. Yapılan madde analizi sonucunda ortalama ayırt edicilik gücünün 0,53, ortalama madde güçlük indekslerinin 0,59 olduğu görülmüştür. Bu değerler, geliştirilen iki aşamalı kavram testinin ayırt edici ve orta güçlükte bir kavram testi olduğu şeklinde yorumlanabilir. Çalışma kapsamında ortaokul 8. sınıf öğrencilerinin basınç ünitesindeki kavramlarla ilgili kavram yanılgılarını belirlemek amacıyla kullanılabilecek 27 maddeden oluşan iki aşamalı kavram testi geliştirilmiştir. Ortaokul 8. sınıf basınç ünitesi iki aşamalı kavram testini öğretmenler ve araştırmacılar kullanabilirler.
