Abstract
The purpose of this study was to identify the effect of learning using 3D-visualization on nucleophilic substitution reaction to improve students^ critical thinking ability. This study used quasi exsperimental one group pretest and postest design. This study involve 68 students from two different universities in West Java. University A have 37 students and university B have 31 students involve at the study. The critical thinking ability test instrument consists of 9 multiple choice questions with reasons. The results showed that learning using 3D-visualization on nucleophilic substitution reaction can improve students^ critical thinking ability. Based on the N-gain result, students of the university A better than the university B, except on ^identifying/formulating criteria to assess posible answers^ indicator of critical thinking ability. It should be increase students^ critical thinking ability especially in the university B through further effort.
