The implementation of project-based learning in STEM activity (water filtration system) in improving creative thinking skill

Abstract

This research is concerned with STEM activity making water purifier filter. The experiment class applies project-based learning, while the traditional class is taught using conventional teacher talk or explanation. This research used triangulation methods. The quantitative methods were applied to analyze student achievement tests according to creative thinking skills in making water filtration design. The qualitative method was applied using observation of student activity, presentations, and interviews for selected students. The student achievement test was analyzed and coupled with pretest and post-test quasi-experimental research. The collected data were analyzed using inferential statistics in the form of an independent sample t-test to express creative thinking skills. The result of the pre-test indicated the sig (2-tailed) of 0.965, with a significant value of 5% (p>0.05). This result indicated two classes were homogenous. The data analysis of the post-test indicated value of sig (2-tailed) 0.00 where p≤0.05, which implied the student achievement test on creative thinking skills criteria in the experimental class was better than that in the control class.
