The purposes of the research were to create and find out the efficiency validation of computer assisted instruction focused on the Plastic Injection Adjusting Machine and Injection Molding Maintenance for the standard 90/90 and to analyze the students’ learning achievement after using computer assisted instruction. The samples were 20 first year diploma tool & die students at Rajamangala Institute of Technology North Bangkok Campus. The students pretested and then studied by using the computer assisted instruction focus on the plastic Injection Adjusting Machine and Injection Molding Maintenance. Finally the students post tested. After that the data was calculated to find out the computer assisted instruction efficiency and analyzed the students’ learning achievement after studying. The result revealed that the computer assisted instruction efficiency was reached the standard 90/90 and the students’ learning achievement increased significantly at 0.05.

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to reading. Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program Subject Electric Power System Analysis Chapter 3-6 based standard and analyses the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 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 analyses the leaning achievement of students after study . The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard Moreover after learning achievement At significant level of 0.05 .
