The purpose of the study was to evaluate the implementation conceptual change strategy assisted by students’ worksheets. The evaluation focused on two aspects involving the direction of misconceptions shift and the reduction of misconceptions. This study followed a pre-experimental research design with one group pretest-posttest design type. The participants of this study were 17 high school students who had already studied the concept of chemical bonds, have a balance visual-verbal learning style and were detected to have a high misconception burden (≥ 37.84%). The significance test for the decreased burden of student misconception was done by using the Wilcoxon Signed Rank Test. The results of this research were: (1) the implementation of conceptual change strategy assisted by student worksheet succeeded in decreasing targeted students’ misconception burdens significantly in the concept of chemical bonds, (2) researchers found 5 types of student misconceptions shift, and (3) the implementation of conceptual change strategy assisted by student worksheet succeeded in dethcreasing quite largepercentage of students with misconceptions (81.54%) in the three attributes, that were concept definition, characteristic, and example/non examples and the biggest decrease occurred in the definition attribute (97.18%). © 2019, Beijing Science Education Innovation center.
