Project based online learning on the concept of the colligative properties of solutions

In an effort to prevent the spread of the SARS-Cov-2 virus, learning must be carried out online, by utilizing several online platforms and social media such as the tiktok application. Innovative media and can reduce student boredom during online learning. In addition, appropriate learning models are needed, such as project-based learning. This research was conducted on the second semester students of the chemical education study program at UIN Sunan Gunung Djati Bandung. 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).
