Purposes of the research were to design and develop Computer Instruction Package on Principle of Object-Oriented Programming and to find out efficiencies effectiveness and leamers satisfaction towards the package. The research tools were: 1) The Computer Instruction Package on Principle of Object-Orientes programming 2) Achievement tests 3) Quality assessment and evaluation form for multimedia software and 4) questionnaire of leamers satisfaction. sampling groups composed of 30 Bachelor first year students from Faculty of Business Administration Program Computer Infomation-Business Computer Rajamangala University of Technology Phra Nakhon. Research results revealed that the efticiency of the Computer Instruction Package was at 81.08/81.05 corresponding with 80/80 criteria. Analysis of pre-test and post-test scores found that the effectiveness aftce the process (E) was at 81.08 it was higher than before the proecss (E) which was at 18.25. Therefore the Computer Instruction Package on Program Design and Development could increase the students learning effectiveness up to 62.83 corresponding with 60 criteria. Mean of satisfaction of the sampling groups was rathe at a high level (4.31). It could be concluded that the Computer Instruction Package on Principle of Object-Oriented Programming had the efficiency that could used for self study.

The purpose of this research were to study the relationship of bio -social factors psychomotor factors and social factors which influenced the 4 -year bachelor degree student major choosing and to make the equations to predict the students choices to further their academic majors for the 4 -year bachelor degree students in faculty of Administration from Rajamangala University of Technology Phra Nakhon. The samples used in this research were 263 4 -year bachelor degree students majored in Accounting Marketing Administration Managing Management and Information Technology in Computers who were studying in semester 2 academic year 2007. The multiple choice questionnaire and estimated matrix were used to collect data. Multi-discrimination analysis quire -square and group division analysis were used as statistical tools.

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to cutting sheet metals based standard 90 / 90 and analyse the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90 /90. Moreover. after learning achievement At significant level of 0.05

The purposes of the research were to create and efficiency validation of computer assisted instruction focused on the practice to CNC Tuming of the standard 90 / 90 and analyse the student leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 23 first year diploma students enrolled in Computer Numerical Control Rajamangala of Technology. North Bangkok Campus. The Researcher using the experiment by let the students do until test before class. And then study by using computer assisted instruction focused on practiced to CNC Turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90 /90 Moreover after learning achievement At significant level of 0.01 .

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to reading Micrometer 0.001 inch based standard 90/90 and analyse the leaning achievement of the student after by using computer assisted instruction The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90/90 Moreover after learning achieverment At significant level of 0.05
