Project based learning STEM to enhance secondary school students’ comprehension on projectile motion

At the beginning of 2020, the Covid-19 pandemic has influenced learning activity where students and teachers have to adapt from face-to-face learning to online learning. This study aims to overcome the issue by developing a learning media with Project-based learning STEM on projectile motion. The media which accommodated the catapult project was developed for secondary schools on google sites. In this research, the media was developed by conducting the Research and Development (RnD) method with the ADDIE model, consisting of five steps: analyze, design, develop, implement, and evaluate. Furthermore, the media was validated by experts and then implemented to the students. Finally, the validation and implementation results were analyzed with four points of the Likert scale. The validation results showed that the average score of the material aspect was 3.8. Meanwhile, the media aspect was 3.3. After the revision, the media was implemented to the students. The average of implementation cores showed that the material aspect was 3.6, the media aspect was 3.6, and the benefit aspect was 3.5. Both validation and implementation results showed that the media was excellent. Therefore, the project-based learning STEM with a catapult project can be applied as a supplemented media for the projectile motion learning process and applied in online learning during the covid-19 pandemic.
