Developing Computer Assisted Instruction (CAI) on Iron-Carbon Phase Diagram for First Year Students of Department of Teacher Training in Mechanical Engineering, Faculty of Technical Education, King Mongkut's University of Technology North Bangkok

Abstract

Abstract  

The objectives of this research were 1) to develop and determine the quality of computer assisted instruction (CAI) on Iron-Carbon Phase Diagram for first year students of Department of Teacher Training in Mechanical Engineering, Faculty of Technical Education, King Mongkut's University of Technology North Bangkok, 2) to determine the efficiency of the developed computer assisted instruction (CAI) on Iron-Carbon Phase Diagram, and 3) to compare learning achievement of students between pre- and post-implementation of the developed computer assisted instruction (CAI) on Iron-Carbon Phase Diagram.

The sample of this research consisted of 30 first year students who registered in the second semester of 2020 academic year in Department of Teacher Training in Mechanical Engineering, Faculty of Technical Education, King Mongkut's University of Technology North Bangkok, obtained based on a cluster sampling.

The results of this research indicated that 1) The quality of the developed computer assisted instruction (CAI) on Iron-Carbon Phase Diagram regarding the content and proceedings was at a high level (=4.45, S.D=0.50), 2) The efficiency of the developed computer assisted instruction (CAI) on Iron-Carbon Phase Diagram was 79.63/74.22, and 3) Learning achievement of students at post-implementation of the developed computer assisted instruction (CAI) on Iron-Carbon Phase Diagram was higher than that at pre-implementation with a statistical significance level of 0.05.
