The Effectiveness of Online Learning in Solubility and Solubility Product Constant Materials on Students’ Analytical Thinking Skills

Analytical thinking skill is a part of higher order thinking skills. The ability to think analytically is very important for students who want to help solve problems and make decisions that can be applied in learning and life. This study aims to determine the improvement of students’ analytical thinking skills on the material solubility and solubility product which is carried out in online learning during the Covid-19 pandemic. This study uses a pre-experimental design, with the model The One Group Pretest – Posttest. The population of this study was students of class XI IPA SMAIT Insantama Bogor in the even semester of the 2019/2020 school year.
