Develop analytical knowledge of basic electrical circuits using the Electrical Circuit Connection Demonstration Board for Secondary 3

Abstract

The objectives of this research are 1) to study knowledge and understanding of basic electrical circuit analysis of Mathayom 3 students in basic electrical circuit analysis, semester 1, academic year 2023; 2) to create and find the efficiency of an electrical demonstration board to develop Know and understand basic electrical circuit analysis for Mathayom 3 students to have efficiency according to the 80/80 criterion. 3) To compare knowledge and understanding of basic electrical circuit analysis between before and after studying for Mathayom 3 students, semester 1. Academic year 2023, the population used in the study includes Mathayom 3 students in free elective courses. (Electrician work) totaling 12 people. The research tools were 1) a test to measure learning achievement on the subject of basic electrical circuits using a skill practice set for Mathayom 3 students. It was a subjective form, filling in 10 answers, statistics used. in data analysis Including percentage, average, standard deviation. and testing of values ​​(t-test) 2) Electrical circuit connection demonstration board to develop knowledge and understanding of basic electrical circuit analysis.
