REPORT ON THE USE OF TEACHING MATERIALS ELECTRICITY AND MAGNETISM COURSE ABOUT ELECTROMAGNETISM MATHAYOM 5 LEVEL

Abstract

The objectives of this research article were 1) to develop the teaching materials on Electricity and Magnetism subject: Electromagnetism for secondary 5 with efficiency according to the criteria 80/80, 2) to find out the effectiveness index of the teaching materials on Electricity and Magnetism subject: Electromagnetism for secondary 5, 3) to compare academic achievement before and after studying the Electricity and Magnetism subject: Electromagnetism for secondary 5, and 4) to study students' satisfaction with teaching materials on Electricity and Magnetism subject: Electromagnetism for secondary 5. The sample group in this research was 72 students in secondary 5 at Princess Chulabhorn Science High School Chonburi, who were currently studying in the 2nd semester of academic year 2017, 3 classrooms where the researcher was responsible for teaching. The tools used for the study included: 1) teaching materials on Electricity and Magnetism subject: Electromagnetism,
2) academic achievement test, 3) inquiry-based learning plan (5E), 4) satisfaction questionnaire. The statistics used were percentage, mean, standard deviation, One sample Z-test and Dependent Z-test. The research results found that: 1) teaching materials on Electricity and Magnetism subject: Electromagnetism for secondary 5 had efficiency according to the criteria was 84.33/83.38, which was in accordance with the specified criteria, which was 80/80. 2) The effectiveness index was equal to 0.708, which indicated that students' knowledge had increased by 70.80 percent. 3) Students who studied with teaching materials had higher academic achievement after using teaching materials than before using learning materials, with statistical significance level at .01. 4) Analysis results of student satisfaction with the teaching materials in all aspects were at a high level.
