Abstract

This study aims to describe the pattern of the relationship between students concept mastery and mathematical problem-solving ability in GLBB material. This is qualitative associative/constructive research. This investigation was conducted with grade X MIA2 students at SMAN 1 Nita. This study's instrument included a test of concept mastery and mathematical problem-solving ability, documentation of student answer sheets, and unstructured interviews. The technique for data analysis consisted of five stages: data collection, description of raw data, data reduction, data categorization, and construction of category relationships. The findings revealed a reciprocal relationship between concept mastery and mathematical problem-solving ability. In addressing physics problems, mastery of concepts and mathematical problem-solving ability play mutually reinforcing roles. The level of concept mastery of students increases with their problem-solving abilities, and vice versa: the higher the level of conceptual mastery, the greater the mathematical problem-solving abilities. The results showed that there was a semantic congruence between issue solving using the Polya step indicator and problem solving at the levels of analyzing (C4), evaluating (C5), and creating (C6).

Abstract

Global warming as one of the physics materials, is a topic that tends to beabstract so it causes difficulties for students. In addition, limited time forlearning activities in class is an obstacle to achieving optimal understanding.Lack of learning time in class can limit students' exploration space. The use ofe-modules based on Problem-Based Learning is an innovative solution tovisualize the phenomenon of global warming through images, videos,animations, and simulations. Limited learning time in class can be overcomethrough the flexibility of using e-modules. The purpose of this study is todescribe the perception of high school students towards the use of ProblemBased Learning physics-based e-modules on global warming material. Emodules are designed to stimulate student learning by utilizing a problembased learning model, where real-life problems are integrated into learning.This research was conducted with a qualitative approach. The subjects of thisstudy were students of St. Gabriel Maumere Catholic High School. Theresearch instruments used are perception questionnaire sheets, documentation,and interviews. The results showed that the percentage of student perceptionon the e-module display indicator was 85.25%, the presentation of material inthe e-module was 82.68% and the overall benefits of the e-module were verygood. Based on the results of data analysis through questionnaires andinterviews, students gave a very good perception of the e-module on globalwarming material.
