Abstract

Students' critical thinking process in solving problems involves several stages, starting from interpretation, analysis, evaluation, inference, explanation, and self-regulation. This research is a descriptive type of research with a qualitative approach which aims to analyze students' critical thinking processes in working on mathematical problems on quadratic functions. The subjects in this research were four class The research was carried out boldly using Google Classroom and Google Meet media. Google Classroom media is used as a medium for giving test sheets to subjects and a place for subjects to collect answers, while Google Meet media is used to interview subjects. Based on the results of work and interviews with the four subjects, the results showed that students' critical thinking abilities included aspects of interpretation, analysis, evaluation and interference. Students 1) did not write down what was asked; 2) make a few calculation errors; 3) incorrectly writing the conclusion; 4) unable to provide logical reasons regarding the steps taken; 5) not re-checking. Teachers are expected to teach concepts related to mathematics, not just provide formulas without providing the origin of why the formula was created.
