The main purpose of the study was to investigate the relation between demographic characteristics mass media exposure knowledge and sexual attitude of the students in Bangkok area. Question aires were used to collect data from a total of 400 samples. The result of the study was as followed: 1. The mass media exposure differs significantly among the sample groups of different sex university and income. 2. The sexual knowledge differs significantly among the sample groups of different sex and university. 3. The sexual attitude differs significantly among the sample groups of different sex university and income. 4. Mass media exposure does not correlate with the sexual knowledge. 5. The sexual knowledge correlates with the sexual attitude.

The purpose of this research were to develop the efficiency of Computer Assisted Instruction (CAI) in Bio – Organic chemistry and to compare the leaming achievement in Bio – Organic chemistry the sample consisted of 35 and 39 student in Department of Food and Nutrition Faculty of Home Economic Technology Ragamangala University of Technology Phra Nokhon 2008 academic year. Research instrument were the CAI and Achievement test in Bio – Organic Chemistry in Carbohydrate. The achievement test comprised 40 item. The data analyzed by statistical computer program. And used mean percentage and compare mean by t-test

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
