IMPROVEMENT AND UTILIZATION OF SINGLE-PHASE AC GENERATOR MODEL IN TEACHING "AC CURRENT" LESSON FOR GRADE 12 PHYSICS IN THE LAOS PEOPLE'S DEMOCRATIC REPUBLIC TO DEVELOP STUDENTS' EXPERIMENTAL COMPETENCE

Abstract

This study aims to explore and understand the "single-phase AC generator model" currently used in secondary and tertiary education in Laos. Based on the difficulties and drawbacks of this equipment, we researched and developed an improved device for physics education in Laos to assess its effectiveness and enhance students' experimental skills. The research method combines theory, investigation, expert opinions, and experimentation. Results show that the newly improved model effectively enhances teaching quality for teachers and learning outcomes for students, while also developing students' experimental skills. The design is compact, durable, user-friendly, and enhances practical abilities for students. Research findings demonstrate the necessity and effectiveness of using this model in education, providing positive support for teaching and learning. Consequently, teachers and students are encouraged to construct such models for educational purposes.
