The purpose of this research was to construct the efficiency of the Computer Assisted Instruction Package for Computer Instructional Package for Drawing 2 Dimension Subject for students in Vocational Certificate Education Level using subject by evaluating the efficiency of the Computer Assisted Instruction Package of the Students to the Computer Assisted Instruction Package for Drawing 2 Dimension Subject with the tools. The sample group was 30 students of Machine Shop Department in Vocational Certificate Education Level Pathumtani Technical College. Analysis by Index of Consistency Level of Difficulty Discrimination Power Average and Computer program. The result of this research was the efficiency 81.14/82.50 higher than the rule of 80/80. This could be concluded that the computer self study packagefor Drawing 2 Dimension Subject using can be used as a learning package efficiently.

The research aims were 1) to develop and find out the efficiencies of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching to be efficient in accordance with defined 80/80 criteria 2) to compare the learning achievement before and after learning of students who studied with the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching and 3) to find out the students’ satisfaction towards the program. A purposive sampling technique was employed to obtain the subjects of this study who were 30 Engineering students of Electrical Engineering Department Faculty of Engineering Rajamanagala University of Technology Pranakhon. They were registered in the second semester of academic year 2013. For instruments were as follows: the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching the evaluation form of the multimedia computer instruction program the students’ achievement tests and the questionnaire of students’ satisfaction. After the experiment the scores obtained from the test were analyzed by using percentage mean standard deviation and t-test. The results of the study showed that the efficiency of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching was 81.22/83.55 which was higher than the specified criteria of 80/80. The scores of after learning with the multimedia computer Instruction program were significantly higher than the scores of before learning at .05 level. And the students revealed that they were highly satisfied with the program.

This research aims to develop a web-based instruction (WBI) applied in the computer technology course. The proposed WBI composed of the following components: lessons of the computer technology course pre-test and post-test exam: determining the effectiveness of the proposed work and user satisfaction questionnaires. It is also evaluated a study achievement and a usage satisfaction by using efficiency and effectiveness test of lessons and satisfaction test of users. In this work users are the second year students in major of Computer Technology Faculty of Science and Technology Rajamangala University of Technology PhraNakhon for 30 students. For experiments the results show that its efficiency is 80.13/83.67 which are met the standard criterion 80/80. In addition the study achievement scores of students who studied the proposed WBI are also higher than students who studied with ordinary courses at the statistical significant level 0.05. Furthermore an average of students’ satisfactions score is 4.20 which determines students satisfy with the proposed WBI at a high-level. Finally it can be concluded that the proposed WBI is effective.

The objectives of this research were to 1) develop the Multimedia Computer Assisted Instruction for Teaching Illuminant Engineering on Interior Lighting Design 2) compare learning achievement between before and after learning 3) evaluate students’ learning progress and 4) study students’ satisfaction on the Multimedia Computer Assisted Instruction. The sample studied were 28 third year students belonging to the field of electrical power engineering faculty of Industrial Education Rajamangala University of Technology Phra Nakon. The instruments of this research included 1) the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design 2) an quality evaluation questionnaire of the Multimedia Computer Assisted Instruction 3) pretest and posttest of learning achievement and 4) student satisfaction questionnaire on the Multimedia Computer Assisted Instruction. The results were as follow: 1. The efficiency of the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design was 81.45/85.71 which was higher than the criteria set of 80/80. 2. The mean score of posttest ( X = 12.68) was significantly higher than pretest ( X = 5.54) at .01 level. ง 3. The evaluation result of learning progress by the method of Average Normalized Gain was 0.77 which was in a high progress level. 4. Students’ satisfaction on the Multimedia Computer Assisted Instruction for teaching Illuminant Engineering on Interior Lighting Design was at the level of the most satisfaction ( X = 4.80).
