Abstract

Skills in selecting the correct information from various information media are needed to get the right information to solve student problems. The purpose of this study was to improve critical thinking skills in the aspects of interpretation and analysis with the problem-based learning model assisted by Concept Scientific Worksheets. This research method is classroom action research (CAR). The research was tested in class XI MIPA 5 of SMA Negeri Balung for 3 cycles of repetition. Data on students' critical thinking skills were obtained from tests of critical thinking skills with indicators of interpretation and analysis. The results of the critical thinking test are calculated to present critical thinking skills and classical completeness. The results of the average analysis of students' critical thinking skills increased from cycle 1 with a value of 62.74, cycle 2 with a value of 65.57, and cycle 3 with a value of 82.59. The classical completeness score in cycle 1 was 52.94, cycle 2 was 50, and cycle 3 was 79.41. This shows that the problem-based learning model assisted by conceptual scientific worksheets can improve students' critical thinking skills with indicators of interpretation and analysis.
