The Development of the Computer-Assisted Instruction on Information in the Computer Subject for Matthayomsuksa1 Nawamintrachinutit Suankularb Wittayalai Samutprakan School

Abstract

The objective of this study were to develop and examine quality of computer-assisted instruction (CAI)  on the topic of Information in Computer in the course of Technology I for Matthayomsuksa 1 students and  to compare learning achievement of the students before and after learning with the instruction. The    sample of the study comprised 50 Matthayomsuksa 1 students enrolling the course of Technology I at Nawamintrachinutit Suankularb Wittayalai Samutprakarn School in the academic year 2/2014, selected by Cluster Random Sampling method. The research instruments were a CAI on Information in Computer, a CAI quality assessment form and a learning achievement test on Information in Computer with Difficulty Index = 0.24-0.80, Discrimination = 0.20-0.52 and Reliability = 0.84. The data were analyzed by using arithmetic mean ( ), standard deviation (S), and paired t-test for dependent sample.

The results showed that the overall quality of the instruction was at a high level ( = 4.30 and S = 0.72). In particular, the CAI presented at a high level of content quality ( = 4.30 and S = 0.75) and a high level of media production quality ( = 4.29 and S = 0.70), with the efficiency E₁/E₂ = 84.40/89.60. Learning achievement of the students was found to increase with significantly higher post-test scores when compared to the pre-test scores at 0.05.
