Improving critical thinking skills and responsibility through discovery learning assisted by student worksheets

Abstract

We conducted classroom action research including preparation, action observation, and reflection to measure the improvement of students' critical thinking skills and responsibilities in mathematics subjects using the Discovery Learning learning model. The sample in this study were students of SMA Negeri 1 Sleman class X MIPA 2, totaling 36 students. The success criteria are 70% in the good category. The results of the study indicate that: (1) the Discovery Learning learning model can improve students' critical thinking skills and attitudes towards responsibility. This can be seen from the students' critical thinking skills tests in cycles 1 and 2. The test results of students' critical thinking skills in cycle 1 were 33% and 56%, and in cycle 2 were 75%. (2) The ability to think critically affects learning outcomes, this can be seen from the increase in the mastery value of student learning outcomes which reached 56% in cycle 1 and 75% in cycle 2, while the results of the responsibility questionnaire filling test were 59% to 74%. From the results of these studies, the Discovery Learning learning model can improve critical thinking skills and attitudes of responsibility that have an impact on the mathematics learning process of students in class X MIPA 2 SMA Negeri 1 Sleman.
