Abstract

Biology learning in ecosystem materials still faces obstacles in the form of limited interactive learning tools, so that it has not been able to optimize students' problem-solving skills. The use of conventional devices that have not utilized digital technology makes the learning process less interesting and does not fully support independent learning. This study aims to describe the validity of google sites-integrated problem-based learning-based teaching modules on ecosystem materials. This type of research is Research and Development (R&D) with the ADDIE (Analyze, Design, Develop, Implement, and Evaluate) development model. The research subjects consisted of 31 students of class X. The instruments used included content and media validation sheets. The validation results showed that the teaching module was in the very valid category, with a percentage of 93% in the content aspect and 93.66% in the media aspect. Thus, google sites' integrated problem-based learning teaching module is suitable for use as a biology learning tool, because it is able to provide interactive, accessible learning, and support the improvement of students' problem-solving skills in a contextual and interesting manner.

Abstract

This study aims to determine the effectiveness of the application of the Problem Based Learning model to improve students' critical thinking skills on the human digestive system material of class XI of SMA Negeri 1 Moutong. The study used a pre-experimental design method with a one group pretest-posttest design approach involving 25 students of class XI IPA2. The research instruments included critical thinking tests (pretest and posttest), learning implementation sheets, student activity sheets, and student response questionnaires. The results showed that the learning implementation reached an average of 94% with the category (very good), student activity 94% (very good), and student response 91% (very positive). The average pretest score of 42.2 increased to 79.2 in the posttest with an N-Gain value of 0.59 (moderate category). Significant improvements occurred in the indicators of providing simple explanations and organizing strategies or actions, increasing from 34.4% and 32% to 92%, respectively. These results indicate that the implementation of the PBL model is effective in improving students' critical thinking skills in the human digestive system.
