Three-tier Test to Identify Students’ Misconception of Human Reproduction System

Abstract: The purpose of this research was to develop a three-tier test of the human reproductive system in identifying student misconceptions. The instrument was developed by Treagust model which has three stages of defining content; obtain information; development of diagnostic tests. A total of 100 students were subjected. All question items consist of 15 items have been classified as valid, with result of reliability analysis equal to 0.717, average test of power difference 0.45, all item problem is in range 0.35–0.67 at level of difficulty, construct validity r = 0.531, N = 100, p = 0.000. False negative content validity test is 6.47% and false positive is 9.07%. Based on the analysis result, this instrument is feasible to identify student misconception.
