An analysis of students’ physics misconceptions in online learning using the four-tier diagnostic test with certainty of response index (CRI)

This study was aimed to determine the level of students’ physics misconceptions in online learning using a four-tier diagnostic test with Certainty of Response Index (CRI). The Certainty of Response Index (CRI) is a method used to measure students’ misconceptions about the material taught by teachers. This research was conducted on 27 students of class X TJTL of SMK BLK Bandar Lampung City. The students worked on a four-tier diagnostic test on fluid material which consisted of 20 items. Based on the results of the research, 11 students knew the concept with an average score of 40.74% in the moderate category, 8 students who did not know the concept with an average score of 29.62% in the low category, and 8 students with misconceptions with an average score of 29.62% in the low category.
