การพัฒนาการเรียนรู้เรื่องประจุและชนิดของประจุไฟฟ้า สำหรับนักเรียนระดับชั้นมัธยมศึกษา โดยใช้กระบวนการจัดการเรียนรู้แบบสืบเสาะ

Abstract

This paper aimed to develop of learning on electric charges and type of electric charges that employing inquiry based instruction technique to high school students. The active learning kits covered two main points consisting of electric charges and types of electric charges with three items of demonstrations e.g. “Static electricity magic”, “How to make the lamp illuminate without plugging in” and “When to attract or repulse using Versorium”. This demonstrations were designed according to the 5E learning cycle including: 1) forming questions from engaging electrostatic phenomena and then linking to the principal concept;
2) designing an experiment to investigate the questions; 3) encouraging the students to provide explanations to support the experimental results; 4) elaborating the relevant facts/details for the students to expand their knowledge and; 5) preparing an assessment and evaluating students’ understanding. The learning kits were performed on three groups of 6-7 high school students from Darunsikhalai school of King Mongkut’s University of Technology Thonburi. It was found that the students had understanding on electric charges and types of electric charges and developed their learning skills, for instance, the skills to form meaningful questions, observing the experiment carefully, analyzing and synthesizing their own understanding that comply with the principal concept. The students had positive attitude towards the subject taught.
Moreover, some students can linked their knowledge to understanding phenomena in nature.
