Abstract

This study aims to identify the need for Problem-Based Learning (PBL) based instructional media on the topic of renewable bioenergy and evaluate its effectiveness in enhancing students' critical thinking abilities. Using a descriptive quantitative approach, the study employed test instruments based on Facione’s critical thinking indicators interpretation, analysis, inference, and evaluation and collected data through pretests and posttests administered to 36 students at SMAN 7 Surabaya. The findings revealed an increase in average scores from 2.06 to 3.64 after the learning intervention, with most students reaching the “good” and “very good” performance categories. Properly integrated learning media, including teaching modules, student worksheets (LKPD), PhET virtual simulations, and PowerPoint presentations, proved effective in supporting contextual and impactful PBL implementation. These results underscore the potential of renewable bioenergy themed PBL media as an innovative tool for promoting students’ critical thinking skills while also fostering scientific literacy and environmental awareness.

Abstract

The IBMRO (Investigation-Based Multiple Representation Online) learning model is designed to improve physics problem-solving skills. However, its implementation requires the right tools so that the objectives can be achieved even though the learning process is carried out online. This study used Algodoo as a learning tool in the IBMRO model on parabolic motion. This study aims to analyze the effectiveness of the Algodoo-assisted IBMRO model in improving students' physics problem-solving skills. This research employed a pre-experimental one-group pre-test and post-test design, with 96 students divided into three classes. Before and after the learning process, students were given tests (pre-test and post-test). During the learning process, observations were made of student activities. After the learning was completed, students were given a questionnaire to assess their understanding of the learning. The pre-test and post-test scores were analyzed using paired t-test, Wilcoxon test, and n-gain. The percentage of observation and questionnaire data was calculated. The results showed that the average score of students' physics problem-solving skills increased significantly a = 5%, The average n-gain of physics problem-solving skills was in the medium category, the average n-gain of each indicator of physics problem-solving skills was in the medium to high category, student activities were relevant to learning, and students had a good response to learning. This study concludes that the Algodoo-assisted IBMRO model is effective in improving students' physics problem-solving skills.
