Abstract:
This study aims to analyze the effect of using an E-module with a wetland
environment-based PBL model on students' critical thinking skills and environmental care
attitudes. This study was a quasi-experimental study with a non-equivalent posttest only
control group design. The study population was 150 students, while the sample was
selected by random sampling. The number of samples in this study was 64 students who
were divided into two classes. The instrument used was a test, namely a question of critical
thinking skills in the form of an essay and a non-test in the form of a questionnaire for
environmental care attitudes. The collected data were analyzed by using Multivariate
Analysis of Variance. The results showed that the significance of the three hypotheses was
0.000, which means less than 0.05 (0,000 <0.05). So, it can be concluded that there is a
positive effect of using the E-module with the PBL model on critical thinking skills and
environmental care attitudes. The novelty of this study integrates the wetland environment
in the learning process using teaching materials in the form of E-modules in the learning
process of the topic of acid-base solutions on critical thinking skills and environmental care
attitudes of students.
