Analysis of Students’ Misconceptions Using the Certainty of Response Index (CRI) on the Concept of Work and Energy in SMA Negeri 1 Gorontalo Utara After Online Learning

Abstract

Research has been conducted on students' misconceptions on physics, especially on the concepts of effort and energy in high school. The targets of this study were students of class X Ipa 1 in SMA Negeri 1 Gorontalo UtaraThe sampling technique is to choose a class that is very active in the school where the research is located.
