The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the micro structure of iron for the standard 80 / 80 and analyze the student learning achievement after using computer assisted instruction. The samples were the 20 first yearBachelor of Science in Technical Education students enrolled in Industrial Engineering Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The Researcher experimented by using pretest and then using the computer assisted instruction focus on the micro structure of iron next the students did the posttest. After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 80 / 80. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.

The purposes of the research were to create and find efticiency validation of computer assisted instruction focused on the fundamental of welding for the standard 90/90 and analyze the students learning achievement after using computer assisted instruction. The samples were the 20 first year Bachelor of Engineering Program in Industrial Engineering Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the fundamental ofwelding and analyzed the students learning achievement after studying. The result revealed that the computer assisted instruction efficiency was efficient for standard 90/90. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.

The purposes of the research were to create and evaluating efficiency of computer assisted Instruction Program for courses of Physical Fitnessbased on Standard 90/90 and analyze the leaning achievement of the student after using computer assisted instruction The samples were 20 first year diploma students in Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The Researcher using the experiment by make pretestand then using the computer assisted instruction program for courses of physical Fitness. After that the students did the posttest againand then calculate to find out the efficiency of the computer assisted instruction and analyze the leaning achievement of students after studying. The result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90/90 and after learming achievement

The pupose of this study was to examine The Factors of the Students That Effect To Produce The Graduates of Rajamangala University of Technology Phra Nakhon. The focused on the level of The Factors from students effecting to produce the graduate of the University Tajamangala of Technology Phra Nakhon. The sample 350 students. Data was collected from a set of Questionnaire and analyzed with a statistical software program. The statistical method were percentahe average t-test One-way ANOVA. The level of statistical significance was set at 05 The result indicated that the level of the Factors from students effecting to produce the graduate of Rajamangala University of Technology Phra Nakhon was high. In hypothetical testing the students was influcnced by the following factors ; Age Faculty Leaming Grade of Education. Education before leaming Household Behavior of students Leaming situation and The satisfied of bachelor degree excepted sex and course of study.

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
