Abstract

This study aims to test the validity and practicality of socio-scientific issues-based
learning modules to train students' critical thinking skills in global warming. The method used
in this study was Research and Development (R&D) using the 4-D development model. The test
subjects were 35 students in class X.E1 at SMA Negeri 2 Batusangkar. The data analysis
technique was a validity and practicality test of expert validation sheets and respondent
questionnaires, as well as a three-tier critical thinking test. The results showed that the validity
of the material in the learning module based on socio-scientific issues was 88%, construct
validation was 100%, and language validation was 95%. The results of the practicality test from
teacher and student questionnaires were 86% and 93%, respectively. The level of students'
critical thinking improved from 55% (fair) to 86% (very good). Based on the results of the
study, it can be concluded that the socio-scientific issues-based learning module to train
students' critical thinking skills in global warming is very valid and very practical to use.
