Abstract

The purpose of this study was to develop a multiple format instrument, in order to measure the development of 12 science process skills. For this purpose a questionnaire with 15 constructed response (CR) type items and one hands-on task was developed. In its final form it was administered to a total of 80 Grade 9 students in four different high schools in metropolitan Ankara, Turkey. The test administration time was set at 90 minutes. The reliability of the instrument was also established and found to be high (Cronbach alpha = 0.88). Initial results suggested that the procedures followed in this study could provide guidance for researchers working on the development of performance tests and activities. Secondly, since the instrument developed in this research study was curriculum-independent it would be useful for curriculum developers who were seeking to know if a science curriculum under development would be able to foster students' attainment of science process skills. Thirdly, the results appeared to imply that a multiple format instrument that included both a hands-on task and paper and pencil items could be successfully developed and used.
