The research aimed to study and compare : 1. foods and nutrition knowledge of adolescence by looking at gender and level of education. 2. the awareness of foods and nutrition by comparing gender and level of education. 3. the practice of foods and nutrition by comparing gender and level of education. 4. study the relationship between knowledge awareness and practice of foods and nutrition of the adolescence in Muang District Prachinburi Province. Tests and questionnaires were used to gather the data from 346 samples. The Stratified Random Sampling was used. The data were analyzed by using percentile mean standard deviation t-test one way analysis of variance and Pearson’s Product moment correlation at 0.01 - 0.05 significant level. The study found that 71.4% of the sample was female and 41.0% was high school graduate. The sampling adolescence had good knowledge of foods and nutrition. Different gender had significantly different level of foods and nutrition knowledge at 0.01 while different level of study had no different level of foods and nutrition knowledge. The sampling adolescence had foods and nutrition awareness at high level Different gender had significantly different level of foods and nutrition awareness at 0.01 while different level of study had no different level of foods and nutrition awareness. The sample group had good foods and nutrition practice at moderate level with no difference between gender and level of study. There was a positive relationship between foods and nutrition knowledge awareness and practice of the adolescence at 0.05.The relationship between knowledge and awareness was moderate and the relationship between knowledge and practice was low.

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

The purposes of this research were to create and evaluate the effectiveness of Computer Assisted Instruction about Tensile test The CAI consisted of 9 lessons The sample was 20 first year diploma students in Tool and die make Department Faculty of Production Technology. Rajamangala University of Technology Phra Nakhon. First of all the students did the pre-test and then they studied via CAI. After that they did the post-test. After using CAI the result was evaluated to find effectiveness and learning achievement was analyzed. The finding showed that CAI effectiveness reached the standard of 90/90 Further more the students knowleage increased 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 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
