DEVELOPMENT OF COMPUTER ASSISTED INSTRUCTION ON CHARTING AND CALCULATING SHEAR FORCE AND BENDING MOMENT DIAGRAMS FOR STUDENTS IN FACULTY OF THECHNICAL EDUCATION IN KING MONGKUT’S UNIVERSITY OF TECHNOLOGY NORTH BANGKOK

Abstract

The objectives of this research were to: 1) develop a computer-assisted instruction (CAI) for the topic of shear force and bending moment diagrams in Mechanics of solids subject, 2) determine the efficiency of the computer-assisted instruction and 3) compare the learning achievement of students after studying with the computer-assisted instruction with criteria, 70%. The sample group of this study was 30 students in the second year of Bachelor's degree from Production and Industrial Engineering program in King Mongkut's University of Technology North Bangkok. The samples were selected based on cluster random sampling. The instruments used in this research consisted of the computer-assisted instruction (CAI), the quality evaluation form, and the achievement tests which had the index of consistency between 0.60-1.00, the difficulty index between 0.63–0.80, the discrimination between 0.20-0.53, and the reliability of 0.83. In addition, the data would be analyzed by using statistics including mean, standard deviation, and t-test for one simple group. The results showed that 1) the computer-assisted instruction had overall content quality and media production technique at a good level ( = 4.37, SD.= 0.49),  2) the efficiency of the computer-assisted Instruction was 80.43 / 76.81that met the set hypothesis, and 3) the students’ learning achievement after studying the computer-assisted instruction was higher than the criteria, 70% with a statistical significance level of 0.05, accepting the set hypothesis.
