Abstract

Critical thinking skills are one of the skills needed in the 21st century. In one of the junior high schools in Pasuruan, students' critical thinking skills are low, so they still need improvement. The goal of this research was the creation of a learning media for an educational kit based on PjBLSTEAM that is considered worthy of being tested for its validity, practicality, and effectiveness in training junior high school students' critical thinking skills on water pollution material. The development procedure was based on the ADDIE model (analyze, design, develop, implement, and evaluate) with data collection techniques using interviews, questionnaires, and pretest-posttest questions. Data analysis techniques were applied using qualitative descriptive techniques, percentage analysis, validity tests, practicality, and effectiveness tests from the paired sample Ttest and N-Gain tests. The results of the media and material validation tests were shown to meet very valid criteria. The results from the teachers and students' feedback showed a very practical percentage. The media was considered effective, as evidenced by the results of the paired sample t-test, which indicated a difference in students' critical thinking scores before and after treatment, and the N-Gain test results, which showed a medium bar value. This research indicates that the learning media developed was valid, practical, and effective for training students' critical thinking skills

Abstract

This research is based on the limited use of learning media which results in students experiencing difficulties in understanding lessons and a lack of learning motivation, which impacts low learning outcomes. This research aims to develop valid, effective, and practical google sites multimedia to improve conceptual understanding and student motivation in the material of the digestive system. The research method used was research and development (RD) with the ADDIE model, namely: analyze, design, development, implementation, evaluation. Data were collected through observation, interviews, and questionnaires. Validation by material experts showed a "very valid" category with a percentage of 87.74%, while media experts reached 90.22%. The effectiveness test produced a significance of 0.000 (0.05), indicating a significant difference between the pretest (63.28) and posttest (89.62) scores, with an average increase in N-Gain of 0.72 (high). The learning motivation questionnaire obtained a score of 88.77% (very high). The practicality test by teachers produced 99.10% and and user responses from students 92.07%, indicating this application is very practical. The research results prove that google sites is feasible, effective, and practical to use to improve students' conceptual understanding and motivation in the digestive system topic
