Analysis and Design of PBL-Based Mathematics Students Worksheet to Improve Critical Thinking Skills

Abstract

Critical thinking needs to be integrated into the learning of mathematics in the 21st century and the industrial revolution 4.0. A learning model that supports the inculcation of critical thinking skills is problem-based. To implement the problem-based learning model, appropriate learning resources are needed. However, existing learning resources do not yet support the development of students' critical thinking skills. This study aims to analyze the needs of learning resources and then design student worksheets for problem-based learning models to improve critical thinking skills. This study used descriptive qualitative method. The subjects of the study were students of Muhammadiyah Middle School. The objects of research are essential skills of thinking, problem-based learning models, and student worksheets. Data collection instruments used interview guidelines, questionnaires, and validation sheets. The data obtained were analyzed using the Miles-Huberman model, which consisted of data reduction, data presentation, and concluding. This study produces an analysis of the needs of learning resources that are appropriate to the characteristics of students, curriculum, and subject matter. The study also provided a valid student worksheet design. This student worksheet design can be used by teachers who want to develop student worksheets that fit the problem-based learning model. This student worksheet design is also designed to improve students' critical thinking skills.
