Development and Study of Learning Achievement of the Multimedia Computer-Assisted Instruction on AC Analysis of Transistor Circuits

Abstract

The objectives of this research were to assess the multimedia computer-assisted instruction on the “AC analysis of transistor circuits” by comparing a learning achievement before and after taking the developed multimedia computer-assisted instruction. Included was the comparison of students’ achievement between normal teaching method with computer-assisted instruction learning, and assessment of the satisfaction of students with the multimedia computer-assisted instruction. The samples used in this study were Electronics and Telecommunication Engineering students, Faculty of Industrial Education, Rajamangala University of Technology, Nonthaburi Campus. Twenty-five Students enrolled in the Electronic Circuits Analysis course for semester 2/2011. The simple random sampling technique was used to divide applicants into two groups, control and an experimental group. The control group was taught with normal teaching methods, while the experimental group received the multimedia computer-assisted instruction. In this research study, the multimedia computer-assisted instruction, achievement test and questionnaire were used for collecting the data. For data analysis of statistics, difficulty, discrimination, validity, reliability, percentage, means, standard deviation, paired t-test and independent t-test were employed. The results of this research showed that the efficiency of multimedia computer-assisted instruction on the ac analysis of transistor circuits was 80.27/80.83. The average achievement of students after studying with multimedia computer-assisted instruction was higher than that of before using it at the statistical significant level of .05. Also, the average achievement of students learning with multimedia computer-assisted instruction was higher than that of normal teaching methods at the statistical significant level of .05. Furthermore, the student satisfaction toward the multimedia computer-assisted instruction was at a high level, both overall and in each aspect of satisfaction.
