Project Penanganan Sampah Masker berbasis STEM Pada Topik Pencemaran Lingkungan Terhadap Creative and Critical Thinking Siswa SMA

Abstract

This study aims to determine the effect of the STEM-based Project-Based Learning (PjBL) model on the topic of environmental pollution on the creative and critical thinking of high school students. The problem of mask waste in Indonesia during the COVID-19 pandemic has increased by 30% to 50%. Mask waste is often found in TPS with an increasing volume. The mask waste problem requires the synergy of various elements of society with different roles. Educational institutions (schools) have an important role in making a major contribution to starting a movement to handle mask waste. Combining the STEM-based PjBL model is effective for handling the mask waste problem, which can bring out good creative and critical thinking. This type of research is a quasi-experiment using two test classes with a pretest-posttest control group design. The research stages begin to formulate the problem until drawing conclusions with the results of the experimental class research
having a high level of creative and critical thinking, while the control class is in the medium category. Recommendations from this study are expected that the PjBL-STEM model can be applied in learning biology so that students are trained in creative and critical thinking skills.
