Beyond Traditional Learning: How the RADEC Model Revolutionizes Inquiry Skills in Basic Science for PGSD Students

Inquiry skills are essential in science education, enabling students to develop critical thinking and analytical abilities. This study aims to evaluate the effectiveness of the Read, Answer, Discuss, Explain, and Create (RADEC) learning model in enhancing the inquiry skills of students in the Elementary School Teacher Education Program (PGSD) during the Basic Science Concepts course. We used a quantitative research method with a pre-experimental design to measure changes in inquiry skills before and after the implementation of the RADEC model. The instruments used included student worksheets and observation sheets to collect relevant data. Data analysis was conducted qualitatively, focusing on the information gathered from student worksheets and observation sheets to provide a comprehensive overview of students’ inquiry skills. The results indicate that the RADEC model significantly improved students’ inquiry skills across all aspects, including observing, questioning and predicting, planning and conducting investigations, analyzing data and information, evaluating and reflecting, and communicating results. The implications of this research emphasize the importance of utilizing innovative teaching models such as RADEC to enhance inquiry skills, ultimately preparing PGSD students to become more effective educators in teaching science concepts at the elementary level.
