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 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 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 ofthis research were to study: 1) the multiple intelligences of First Year Students in Rajamangala University of Technology Phra Nakhon 2) the ability in English language reading of First Year Students in Rajamangala University of Technology Phra Nakhon 3) the relationship among the Multiple Intelligences and English Reading AbUity of First Year Students in Rajamangala University of Technology Phra Nakhon. The samples of this study were 137 first year students from 9 Faculties in Rajamangala University of Technology Phra Nakhon in the academic year of 2008. The research instruments were the multiple intelligences survey developed by the researcher from Memletics Learning Styles Inventory and the English language reading test constructed by the researcher. The data were analyzed by means of arithmetic mean standard deviation Correlation Coefficient

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.

This project was to study the properties of basement soil which used portland cement laterite soil and slag as the main ingredients and to investigate its appropriate ration to be used for pavement improvement. By using 95% of laterite by weight and 5% of the mixed Portland cement and slag by weight the amount of portland cement to that of slag at 5% : 0% 3.5% : 1.5% 2.5% : 2.5% 1.5% : 3.5% and 0% : 5% by weight were mixed together. Then the derived mixture was put together with the laterite which was the major material. The study showed that the ration at 3.5% of portland cement and 1.5% slag to the laterite at 95% provided the best basement soil in quality. At this ration it saved the cement content used as well. At this ration it gave soil cement higher plasticity. Its CBR is high as well. Moreover it provided the standard unconfined compressive strength according to that defined by The Department of Highway of Thailand.
