The Ecosystem Problem-Based Learning E-module To Train Critical Thinking Skills During COVID-19 Pandemic

Abstrak

The form of Biology teaching materials nowadays was still limited, in contrast with digital platforms’ fast development. Incomplete learning experiences cause difficulties in understanding difficult topics such as ecosystems, which lead to critical thinking skills training obstacles, more so during the COVID-19 pandemic. Therefore, it was necessary to develop teaching materials to train this skill. The problem-based learning model required the students to actively solve the problems, in turn training them to think critically. The purpose of this research is to develop a valid, readable, and practical ecosystem problem-based learning e-module to train high school students’ critical thinking skills. This research used the ADDIE model, data gathering use validation, Fry Graph, and questionnaire method on the 10 students of SMAN 1 Dawarblandong grade 10 as the participant, and the descriptive-quantitative techniques used to analyze the data. The result of this research, namely the developed e-module with authentic problems and hands-on activities; the 3.78 validity score; the suitable readability for 10th-grade students; and 96.94% positive response on practicality. Accordingly, the ecosystem problem-based learning e-module to train high school students’ critical thinking skills declared very feasible in terms of validity, readability, and practicality.
