The purpose of the study is a describ e students activities and analyze the products produced by student, and describe the improvement of problem solving ability after the application of project based learning in online learning on concept colligative properties. The method use was pre-experiment with one group pretest-posttest design, which was designed without any control class. The results of hypothesis test shows that the tcount value is 13,17, while the ttable is 2,45, so Ho rejected and Ha is accepted, so there is an increase in problem solving abilities after the application of project based learning in online learning on the concept colligative properties. © 2023 Author(s).
