DEVELOPING THREE-TIRE MISCONCEPTION TEST ABOUT REGULAR CIRCULAR MOTION

This study aimed to develop a test which determined whether students have misconceptions about regular circular motion. The developed test has seven three-tiered items. The second phase of the test items is multiple-choice requiring the reason of the answer and it includes some possible misconceptions. In this phase, the choices determined as a result of the semi-structured interview with 10 students and there has been also remained an open ended choice. The reliability coefficient found as 0.68 by a pilot implication which 68 students attended. The test applied to 286 teacher candidates who are training in certain departments of Gazi Education Faculty in 2005-2006 academic years. As a result, it found that the students have misconceptions in certain levels which were estimated before. The students have misconceptions mostly about velocity and force at regular circular motion. Additionally, the students make out causal connection between circular motion and centripetal force.
