Journal Title: International Journal of Current Science Research and Review - Year 2024, Vol 7, Issue 06
Abstract
The Independent Curriculum is a solution to the tight competition for human resources in the 21st century. The critical thinking skills needed in the 21st century can be improved through studying chemistry, especially acid-base materials. The problem-solving learning model is an appropriate learning model for understanding acid-base materials and can improve students’ critical thinking skills. Learning media that can be used in chemistry learning are electronic modules. The aim of this research is to develop a problem-solving-oriented e-module to improve critical thinking skills in acid-base materials. The development model in this research uses the 4D model by Thiagarajan. The development of problem-solving-oriented e-modules was declared suitable for improving students’ critical thinking skills in acid-base material in terms of validity, practicality, and effectiveness. Validity is seen in content and construct validity, both of which received a mode value of 5 in the very valid category. Practicality can be seen from the results of the student response questionnaire, which obtained a percentage of 98.75℅ in the very practical category and is supported by the results of observations of student activities. Effectiveness can be seen from the results of the students’ critical thinking skills pretest and posttest, which obtained a significance value of 0.00 using the paired sample t-test.
