The Effectiveness of Guided Inquiry Learning Model using the Virtual Laboratory on Acid-Base Materials to Improve Analyzing Skills

Abstract

This study aims to describe the effectiveness of the guided inquiry learning model using the Virtual Laboratory on acid-base material in improving students analyzing skills. The population in this study were all students of class XI science at SMA Negeri 9 Bandar Lampung for the academic year 2021/2022 with a sample of class XI IPA 7 as the experimental class and XI IPA 6 as the control class. This research method is quasi-experimental with the Matching-only pretest-posttest control group design. Sampling was carried out using purposive samplingtechnique. Hypothesis testing used a difference test of two averages (t-test) on the posttest value of the experimental class and the control class. The results showed that the average posttest value of the experimental class was higher than that of the control class and that the experimental class had a high average  n-Gain category. Furthermore, the results of the average difference test using the t-test showed that there was a significant average difference between the experimental class and the control class. It can be concluded that the use of a guided inquiry learning model using the Virtual Laboratory on acid-base material is effective for improving students analyzing skills.
