The purposes of this research are 1) to create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) 2) to develop and to find out quality the create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) and to achieve efficiency according to a set of 90/90 criterion. The samples for this study were 48 second year students of Bachelor of Technology Program in Radio and Television Broadcasting Technology studying this course in the first semester of 2011 academic year at Rajamangala University of Technology Phra Nakhon. The samples were selected by simple random sampling. The research tools used are the computer multimedia through the Internet an achievement test evaluation forms for quality assessment. Statistics used for analyzing the data were percentage and mean. The results of the study revealed that the computer multimedia instruction through the Internet was ranked as a very good level by content experts and as a very good level by educational technology experts and had its efficiency of 94.80/96.60 it was higher than criteria set 90/90

The learning of Educational Quality Assurance topic has been important for students and educators. The nature of the topic has more complex contents of key performance index (KPI) and students are asked to learn by following the text books. Consequently the topic is not interested and the students and teachers lack of interaction during learning on the topic. Therefore this study developed the multimedia Educational Quality Assurance to provide a self-study and to enhance students’ understanding in this matter more. The sample group consisted of 60-third year undergraduate students on Technical Education learned Quality Assurance course. The results of this study shows that participating students have post-test score more than pre-test score significantly with the confidence level of 95% and have learning progression (normalized gain =0.62) implying that they could learn more with the developed multimedia. Moreover they get high satisfaction (4.52) with the developed multimedia.

The purposes of this study were to compare the progress in Thai enunciation skill of students at Rajamangala University of Technology Rattanakosin Wangklaikangwon Campus before and after using electronic medias and to find out freshmen’s attitude toward using electronic medias to develop Thai enunciation skill . The sample was 40 freshmen of Rajamangala University of Technology Rattanakosin and taking Thai for communication course in the first semester of the 2011 academic year. The study was carried out for 1 month by learning plan with the teacher before practicing unlimited time by themselves with the electronic medias 10 times with researcher consultation. The research instruments were 1) the electronic medias to develop Thai enunciation skill 2) the pre-test and post-test of reading 3) attitude questionnaire. The data were statistically analyzed using percentage by formula E1/ E2 and t-test The results of the study revealed that the Electronic Medias average percent effective E1/E2 is 80.15/88.90 after using E–learning the progress in Thai enunciation skill of the freshmen increased at the .05 level of significance and the freshmen’s attitude towards using electronic medias to develop Thai enunciation skill was very good.

The electronic science is complicated and highly abstract. The contents are abstracts and difficult to understand. This research was developed by computer assisted instruction lesson on electronic circuit multimedia using jigsaw puzzles. The objective was studied the achievement of circuit electronics and the satisfaction of students in grade 9. There were 132 students. The results from the pretest and posttest of computer assisted instruction lesson on electronic circuit multimedia. They have highly scores and satisfied.

The purpose of this research were to create and determine the efficiency of computer assisted instruction lesson on electronic circuit multimedia for secondary school students (grade 9) Triamudomsuksanomklaononthaburi school. The research sample consisted of 120 students of secondary school students (grade 9) during semester 2 in the academic year of 2012. The data were analyzed using mean standard deviation level of difficulty and discrimination power. The results found as follows : The efficiency of computer assisted instruction lesson electronic circuit multimedia for secondary school students (grade 9) is 80.15/83.35 and the students’ satisfaction with the computer assisted instruction lesson electronic circuit multimedia was at highest level ( = 4.60 S.D = 0.74)
