The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced disassembly and assembly fuel injection pump type VE based standard 90 / 90 and analyse the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 16 first year diploma students enrolled in Mechanical Power Rajamangala University of Technology Phra Nakhon 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 practiced disassembly and assembly fuel injection pump type in-line. 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 basic file based standard 90/90 and analysis the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year bachelors degree 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 Orthographic Drawing for First Angle Projection and Third Angle Projection. 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 analysis 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

This research was to develop the computer application program which was called CivilLabPro for civil engineering laboratory. It consists of analytical part and educational part. Both are designed to use database together and they can use either personal computer or internet system. The analytical part is composed of 15 soil mechanics laboratory and 16 materials testing laboratory that it was written by using visual basic language and it could report not only numerical formats but also graphical results. The results of calculation were stored with database system which wrote by using SQL language. The educational part comprises self study and self exam that it was written by using HTML language and SQL language. The effectiveness of this application was evaluated by questionnaire and opinion in items as follows: easiness of usability accuracy of results and rightness of subject matter. From the evaluated results found that most people are satisfied with this application and the results were accuracy. This evaluation was summarized that it was good standard and it was capable to use in electronic teaching and working.
