Abstract

This study aims to analyze the effect of a guided inquiry learning model combined with advance organizers on enhancing high school students' critical thinking skills in Simple Harmonic Motion (SHM). Utilizing a quasi-experimental design, this quantitative research involved two experimental groups and one control group at senior high schools in Mataram. The experimental groups engaged in guided inquiry learning integrated with concept maps and short videos as advance organizers. Data were collected through pre-tests and post-tests using a five-item essay instrument validated by experts, then analyzed using normalized gain (N-gain). The findings revealed that the critical thinking skills of both experimental groups increased in the high N-gain category, whereas the control group showed a moderate increase. Among the critical thinking indicators, "providing simple clarification" achieved the highest gain, while sub-topic analysis indicated the greatest improvement in the "restoring force" concept. This study concludes that integrating advance organizers into guided inquiry learning effectively establishes an initial cognitive framework and significantly enhances students' critical thinking skills in physics education.

Abstract

Inquiry learning fosters physics problem-solving skills but often fails when students lack stable initial knowledge. Conversely, the Advance Organizer (AO) model excels at activating cognitive structures and meaningful learning. This synthesising review analyzes the strengths, limitations, and impacts of integrating guided inquiry with AO on high school students' physics problem-solving abilities based on a comprehensive literature review. The results show that the model's primary strength is providing effective kognitive scaffolding, significantly increasing the "focus the problem" indicator. However, the main limitations include structural time-management challenges and high dependency on students' prerequisite mathematics skills, leaving the "describe the problem" and "evaluate solutions" indicators at moderate levels. Digitalizing AO materials and embedding mathematical mini-scaffolding are practical solutions to maximize this integrated approach.
