The research aimed to exploratory factor analysis of computer self-efficacy of undergraduate students at Department of Information Technology Faculty of Science and Technology Suan Sunandha Rajabhat University. The sample used in this study included 80 students who studied in level 3 in second semester of academic year 2012. The data collection tool is a questionnaire use a 5 rating scale. The finding revealed that the computer self-efficacy of undergraduate students was divided into 4 groups: group 1: Computer software and hardware consisted of 6 variables can be explain the computer self-efficacy 40.58%. Group 2 : Computer skills consisted of 3 variables can be explain the computer self-efficacy 11.19%. Group 3 : Data management consists of 2 variables can be explain the computer self-efficacy 9.50%. Group 4 Advanced Computer skills consists of 2 variables can be explain the computer self-efficacy 7.82%. which factors in 4 group will be able to explain the computer self-efficacy 69.08 %

The purposes of this research were: 1) to develop Web-Based Instruction (WBI) on “Kingdom of Ayutthaya and Kingdom of Thonburi”กusing student team achievement division technique; 2) to evaluate if the WBI meets an 80/80 efficiency criterion; 3) to compare the students’ learning achievements by pre-test and post-test; and 4) to examine student satisfaction towards the WBI. The sampling group selected by purposive sampling was 25 primary education (grade 5) students in the second semester of academic year 2012 at Wattrithosathep school in Phra Nakhon district Bangkok. The research instruments consisted of two unit of WBI; a learning achievement test administered before and after the learning; and the evaluation form of the student performance. The statistical tests employed to verify the efficiency of the WBI were the E1/E2 efficiency index and t-test. The research result revealed that the efficiency of the developed web-based instruction (WBI) was 84.00/82.80 which was higher than standard criterion 80/80 and comparative of student’s achievement it was found that the student achieved learning progress significantly level of .05. Finally it was found that the learners opinion after using the developed web-based instruction (WBI) was very satisfactory.

The objectives of this experimental research were: 1) to develop Web-based Instruction (WBI) on “Op-Amp and Linear IC Simulation Using Multisim Version 11.0 Case Study of Chainat Technical College 2) to evaluate the developed WBI 3) to compare the students’ learning achievements before and after using the developed WBI and 4) to find the students’ satisfaction after the developed WBI. The sample of this research was 30 students in Vocational Diploma at Chainat Technical College in the academic year 2/2012 selected by purposive sampling method. The tools used in this research were the six lessons of the developed WBI using Moodle pretest exercises posttest and worksheets. The results of this research were shown as follows: 1) the developed WBI included 6 learning lessons. 2) the efficiency of the WBI was 83.14/80.20 higher than the criteria. 3) the students effectiveness after using the developed WBI was significantly higher than before using it at .05. 4) the students’ satisfaction was at a good level. In conclusion the developed WBI can be used for the target group properly.

The purposes of this research were : 1) to develop Web-Based Instruction (WBI) on Official Letters part of the Word Processing Applications Subject using Demonstration Technique; 2) to evaluate if the WBI meets Meguigans efficiency criterion; 3) to compare learning achievements of learners before and after studying by the developed WBI; and 4) to evaluate students’ performance after studying the developed WBI. The sampling group recruited with purposive sampling method were 20 second-year vocational certificate students who registered in the second semester of academic year 2012 majors in Business Computer at Bunharn-Jamsai Polytechnic College Suphanburi province. Applied research tools included one unit of WBI’s evaluation form pre-test and post-test learning achievement test and WBI post-test Students’ performance assessment form. Applied statistic tools included Meguigans efficiency value t-test mean and standard deviation (S.D.) Research findings showed that 1) the efficiency of developed WBI was 2.26 which higher than the Meguigans’s standard value at 1.00. 2) post-test learning achievement was statistically significant higher than pretest at .05 3) students’ post-test performance was at good level. We therefore could conclude that the developed WBI can be utilized as teaching material for students with different computer background.

The purposes of this research were 1) to construct and evaluate the efficiency of the Computer Assisted Instruction (CAI) on Nuclear Physics class to have 80:80 effectiveness standards. 2) to compare learning achievement between pre-test and post-test scores after using the CAI 3) to study student’s opinion about CAI. Samples were the second year of Science and Technology students of the Rajamangala University of Technology Thanyaburi in 2011 academic year selected by simple random sampling. The first test was done by one-to-one evaluation and the second one by a small group in order to revise the CAI before implementing within the subject. The efficiency of the CAI was evaluated by experts both in content and production technique of the courseware. The results of this research were shown : 1) the CAI on Nuclear Physics contained the effectiveness at 87.00:85.33 which was higher than the standard criterion set (80:80) 2) the comparison between pre-test and post-test was found that the post-test score of students who studies with CAI were significantly higher than the pre-test score at .05 level and 3) the mean score of the student’s opinion about CAI was 4.35 shown that most of them satisfied the CAI on Nuclear Physics at good level.
