The Influence of Virtual Chemistry Laboratory Media on Students' Understanding of Submicroscopic Level and Student Activity Grade XI

摘要

The purpose of this study was to analyze the influence of virtual chemistry laboratory on students understanding of submicroscopic level and student activity in solubility and solubility product topic. This research was descriptive analysts. This research was conducted in State Senior High School 1 Binjai. Sample of this research was 64 students that divided into two classes as experiment class and control class. Experiment class was learned by using virtual chemistry laboratory while control class was learned without using virtual chemistry laboratory. In analyzing student understanding of submicroscopic level, students were given a written test in the form of worksheet (essay test) consist of 10 questions. Student activity were observed during teaching and learning activity by using observation sheet. The result obtained that (1) Students understanding of submicroscopic level that is learned by using virtual chemistry laboratory media is higher than the students understanding of submicroscopic level that is learned without using virtual chemistry laboratory (2) Student activity that is learned by using virtual chemistry laboratory media is more active than the student activity that is learned without using virtual chemistry laboratory.
