Development of Computer-Assisted Instruction on Drafting Lines for Mathayomsuksa 4 Students at Ratwinitsuvarnnabhum School Using Authentic Learning

Abstract

The objectives of this research were: 1) to develop computer-assisted instruction lessons on drafting lines for Mathayomsuksa 4 students at Ratwinitsuvarnnabhum School using authentic learning, and 2) to develop practical skills in drafting lines for Mathayomsuksa 4 students through authentic learning. The sample consisted of 48 Mathayomsuksa 4 students selected using purposive sampling from those with below-average academic performance. The students were divided into two groups: an experimental group of 24 students and a control group of 24 students. The tools used in the study included 1) learning management plans, 2) computer-assisted instruction lessons, 3) an academic test, and 4) a practical skills assessment. The statistical methods used for data analysis included mean and standard deviation. The research results showed that 1) the computer-assisted instruction on drafting lines for Mathayomsuksa 4 students using authentic learning had a value of 82.17/83.75, which is higher than the established criterion of 80/80, and 2) the comparison of practical skills between the experimental group, which used computer-assisted instruction, and the control group, which used regular teaching methods, indicated that the experimental group had a mean score (X) of 51.29 with a standard deviation (S.D.) of 2.91, while the control group had a mean score (X) of 45.42 with a standard deviation (S.D.) of 3.09. This comparison revealed that the practical learning skills of the experimental group were higher than those of the control group.
