The purposes of the research were to create? and efficiency validation of computer assisted for the courses of practiced to wooden joint 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 development of Computer-assisted Learning Program to rectify the weakness of third year students of Rajamangala Institute of Technology Bangkok Commercial Campus on the concept of mathematics polynomial factor. Mathematics can develop student thinking in system reason have effective problem solving and can use for other tool subject but effective lesson on mathematics to leave media with admire media is Computer-Assisted Instruction. The purpose of this experimental research was to develop the efficiently mathematics computer assisted instruction with the effectiveness of 80180 and to compare learning achievement on polynomial factor to pre and post test in computer-assisted instruction to rectify the weakness of basic mathematics of the third year students of Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus in the first semester of the 2006 academic year of two 60 students groups with specify experiment one 39 students group. The findings of this study revealed that the computer assisted instruction to rectify the weakness of Mathematics Polynomial Factor had the effectiveness of EIE2= 80.89/81.58 which higher than 80/80 criterion and the students who were learned with Mathematics Polynomial Factor got significantly increased at the 0.05 level.

The purposes of the research were to create and efficiency validation of computer assisted for the Computer for Jewelry Design based standard 90/90 and analyse the leaning achievement ofthe 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 Computer for Jewelry Design. After that let students do the unit test again at the class and calculate to fmd out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study . The research result revealed that the efficiency ofthe computer assisted Instruction was efficient in standard 90/90 Moreover after learning achievement At significant level of 0.05.

The purposes of this research were to create and evaluate the effectiveness of Computer Assisted Instruction about Tensile test The CAI consisted of 9 lessons The sample was 20 first year diploma students in Tool and die make Department Faculty of Production Technology. Rajamangala University of Technology Phra Nakhon. First of all the students did the pre-test and then they studied via CAI. After that they did the post-test. After using CAI the result was evaluated to find effectiveness and learning achievement was analyzed. The finding showed that CAI effectiveness reached the standard of 90/90 Further more the students knowleage increased at significant level of 0.01
