A Construction and Efficiency Validation of Web-Based Instruction for the topic AC Circuits\, Vocational Certificate Level, Lopburi Technical College

Abstract

The purposes of this research were (1) to construct the Web-Based Instruction on AC circuit, (2) to validate the efficiency of the Web-Based Instruction on AC circuit, and (3) to compare learning progress of the students with various learning skills after using the Web-Based Instruction. The Web-Based Instruction was applied to 30 students sampled from first – year vocational students of Lopburi Technical College, semester 2/2011. The research results were indicated that, 1. The Web-Based Instruction consisted of 5 lessons, 22 objectives, 41 slides, 9 animations and 50 test items. 2. The Web-Based Instruction had efficiency of 81/80.06 which was consistent to the predefined criterion 80/80. 3. There was no significant difference at the level of .01 between the students with various learning skills who learned by the Web-Based Instruction.
