Abstract

The objectives of this classroom research were to create a computer assisted instruction (CAI) program for the course “Principle of Fibers” for Home Economics students, to study and compare posttest achievements of the students using regular classroom and CAI methods, and to investigate the satisfaction of the students studying via the CAI method. The sample group was Home Economics students enrolling in the course in the second semester of the academic year 2009. They were 26 students. The research instruments included the CAI program on Principle of Fibers, the learning achievement form, post lesson exercises, and the CAI satisfaction evaluation form. The data were analyzed to obtain percentage, mean, standard deviation and distribution co-efficient. The t-test was utilized to compare learning achievements. The data on users’ satisfaction were analyzed to obtain mean and standard deviation. The study results are as follows: 1. The CAI program was created by using the Dreamweaver Program, CS3. It was composed of four lessons which included fiber classification, cellulose fibers, protein fibers, and inorganic fibers. Each lesson contained the objectives, main contents, an exercise, and learning achievement assessment. 2. The highest progress scores went to the lesson on inorganic fibers at 24.62 percent and the lowest scores to the lesson on cellulose fibers at 14.42 percent. The overall progress scores were at 24.68 percent with the mean of 67.54 and the standard deviation of 10.10. 3. When learning achievements of the group control, it is found that the average progress scores increased 19.45 percent with the mean of 36.54 and the standard deviation of 5.74. The average progress scores of the group sample increased 18.90 percent with the mean of 35.00 and the standard deviation of 7.69. When the in-group learning achievements of the two groups were compared, it is found that the progress pre- and posttest scores were significantly different at a 0.05 level. However, when learning achievements between of the two groups were compared, it is found to be no different. 4. The study of investigate the satisfaction of the students studying via the CAI method was found that they were more satisfaction on all item.
