Abstract

One of the obstacles for students when studying the human circulatory system is the difficulty of students in distinguishing the large circulatory system and the small circulatory system. The purpose of developing the prototype of props is to make students better understand in real and detailed terms about the blood circulation process in the human body, so far, students have only used images as visual media, and students can be motivated and learning is not spared, so that student learning outcomes can improve. The purpose of making a circulatory system model of children's learning motivation is to provide a concrete picture of information and new ideas and unite the material that the teacher will convey to the knowledge that will be given to the child, so that the material presented by the teacher can be well received by students. Props are made using styrofoam material, which is designed in such an attractive way to be representative of human blood circulation. This research is part of design-research with small-scale class trials. A small-scale trial of a prop prototype involved seven junior high school students in Bojonegoro Regency, East Java. After being given an explanation and participants tried the prop prototype, they were given a questionnaire to measure students' interest and motivation for the prototype props that had been developed previously. The result obtained from this study is that students have new experiences by learning to use props. Participants were very interested and motivated in using prototypes of human circulatory circulation styrofoam props. The results of small-scale trials indicate that the props prototypes that have been developed are suitable for use in large-scale trials. Keywords: Teaching aids, blood circulation, science learning

Abstract

This study aims to describe students' perceptions of the RADEC (Read, Answer, Discuss, Explain, Create) learning model in enhancing critical thinking skills at junior high school level. Employing a quantitative descriptive approach, the research involved 34 eighth-grade students from SMPN 54 Surabaya as participants. Data collection utilized a validated student response questionnaire designed to assess various aspects of the RADEC model. Collected data were analyzed using descriptive statistical techniques, including mean calculations, frequencies, and percentages. The findings indicate that students responded positively to the implementation of the RADEC model, with an average percentage response of 96.51%, indicating very high acceptance. These results affirm that the RADEC model is effective in enhancing learning motivation, active student participation, and ease of understanding the material. Furthermore, the model successfully enhances students' critical thinking skills, aligning with the primary aim of the study. The implications of this research support further development and implementation of the RADEC model within the educational context of Indonesia, aimed at strengthening the quality of learning at the junior high school level.

Abstract

In the rapidly evolving contemporary era, countries globally, including Indonesia, are compelled to adapt, with the Partnership for 21st Century Skills (P21) highlighting the crucial role of Critical Thinking, Creativity, Collaboration, and Communication (the 4Cs) for student success in the 21st century, yet traditional teacher-led learning often overlooks critical thinking skill development, contributing to low proficiency levels evident in assessments like the Programme for International Student Assessment (PISA). This study aims to describe the implementation of the Read, Answer, Discuss, Explain, and Create (RADEC) model on critical thinking skills in vibrations. The research design employed is descriptive through a one-group pretest-posttest design. The subjects of this study were 34 students in class VIII-A at SMP Negeri 54 Surabaya during the even semester of the academic year 2023/2024. Data collection techniques involved observation, tests, and questionnaires. Research instruments included learning implementation observation sheets, critical thinking skills tests, and student response questionnaires. The test results were analyzed using N-Gain and paired t-tests. The study's findings revealed that implementing the RADEC learning model on vibrations met the criteria very well, with a mode fully implemented. The student's critical thinking skills improved by an N-Gain analysis result of 0.38 and a paired t-test result of 0.000. The students also highly accepted the learning process using the RADEC model in the topic of vibrations, with 86% of statements strongly agreeing. Based on the description above, implementing the RADEC model can enhance students' critical thinking skills regarding vibrations.
