The purpose of this reserch was study status problems and needs in media utilization of instructors of Rajamangala Institute Technology Chotwet Campus. Reserch gathers information from population 47 instructors. Quastionnaires were reserch tools. Percentage mean and standard deviation were used for data analysis. The result revesled that There was moderate in media utilization Tesching method and instruction were used moderately such as description discussion and demonstration highly used fechnique was experiment. Tools and equipments were used wodeklately such as loud-spesker overhead transparency projector were used highly. Instructional medias were used moderately highly used matenak were transparencies. transparent pens boards and resl meterials. The problem in media utilization was moderately perparation and buying had a moderste problem. High problem was lack of comveniency to produce educational media such as personel officers tools materials equipments buildings places and lack of budget in order to buy educational media. Chosen and use in educational media had a little bit problem but there weremoderately level in time consuming to prepare themselves and complicated to move. Quality and quantity of educational media had a moderste problem such as places rwewnt suitable with media utilization couldnt control the light of projectors amount of educational medias weremt sufficient with needs. SeNice had a moderate problem highly problem were lack of personnel to make photoes slides cassette videotape and lack of personnel to produce graphic chart and portary works for teaching compose not enough. The need of media utilization was highly in tools and equipments. Moderately needs were overhead transparency projectors and transpatent pens. The following needs were opaque projectors and projectors videotapes. Service had highly needs such as buying high quality educational media as a teaching compose The following was preparatory necessary educational media such as overhead transparency projectors loud-speskers and microphones permanency in all of class rooms.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the office automation practice for the standard 90 / 90 and analyze the student leaning achievement after using computer assisted instruction. The samples were the 17 Bachelor of Business Administration Program in Management Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the practiced to prepare office equipment in learning next the students did the posttest. After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students learning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 90 / 90. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.
