Abstract

The purpose of this study is to develop an achievement test which includes the basic concepts about the subject of sound and its properties in middle school science lessons and which at the same time aims to reveal the alternative concepts that the students already have. During the process of the development of the test, studies in the field and concepts about sound were reviewed. Test items were prepared by taking the views of experts. 234 9^th graders during the academic year 2013-2014 participated in the study for the pilot and actual implementation. 85 questions prepared initially were reduced to 43 multiple choice questions with four choices following reliability and validity studies. KR-20 reliability coefficient of the 43 question sound achievement test was found as 0,83. The results show that the prepared sound achievement test is reliable.
