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

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced disassembly and assembly fuel injection nozzles of Diesel Engine based standard 90/90 and analyse the learning achievement of the student after by using computer assisted instruction. The subjects in the study were 11 second year diploma students enrolled in Mechanical Power Department 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 disassembly and assembly fuel injection nozzles of Diesel Engine. 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 learning 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 make body of ornaments 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 Researcherusing 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 signifecant level of 0.05.

The purpose ofthis research is to study the factors affecting the undergraduate students achievement on Research Methodology Course Rajamangala University of Technology Pranakhon Chotiwet Campus. The sample groups in this research are the third year students of Chotiwet Campus majoring in Food and Nutrition (4 -year -Programme) totaling 133. The research was done by a definitely random selection. The instruments used in data collection are the questionnaires and the statistics by means ofvarious uses namely percentage value frequency value Arithmetic means value standard deviation value Pearson product moment coeffICient correlation and Step -wise multiple regression analysis. The results ofthe study are asfollow. 1. Most ofthe sample group arefemale their grade point averages are 3.00-3.49. They require further their studies in Master degree. As for thefuture career they want to own private business. The mid-term scores made by the sample group averages at 19.5. Asfor the attitude of the sample group to do research most ofthe students thought that it was diffICult but they can possibly do. Some students revised their lesson from time to time. In term ofthe class participation it is found that the sample group can take part in class in an moderate level and personal problems ofthe sample group are in a low level. 2. Factors afficting the students achievement on Research Methodology which imply signifICantly in statistics at 0.05. Can be divided into twofactors (1) cumulative grade point average and (2)studentsproblem ofhow to adjust to the study environment. 3. The two factors can be predictedfor the achievement on Research Methodology at the percentage of31.2 and can beformed as model ofthe Research Methodology achievement predictive equation as follow Y=11079(x1)+3349-1081(x7)
