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 study were: 1) to develop the model of a participatory learning process for conserving the forest-resources of communities around Doi-Khun-Tan National Park 2) to compare knowledge attitudes and behaviors of the samples’ in conserving the forest resources and 3) to study the satisfaction of participatory learning process. The sample selected by a purposive sampling consisted of 48 subjects representing the communities around the area of Doi Khun Tan. The instruments included all these: 1) an interview 2) a participatory learning process program for conserving the forest-resources the area of Doi Khun Tan National Park 3) a questionnaire about the knowledge attitude and behavior of conserving forest resources and 4) a questionnaire about their satisfaction with the program. The data elicitation was drawn from three sources: 1) interviews and brainstorming 2) the assessment of the knowledge attitudes behaviors by the questionnaire and 3) the assessment of the satisfaction with the participatory learning process by the questionnaire. The study revealed these findings: 1) the participatory learning process of model fell into 6 steps consisting of a) the analysis of communities key informants and literature reviews b) the implementation of the knowledge to conserve the forest resources c) the implementation of the attitude towards conserving the forest resources d) the implementation of the behaviors of conserving the forest resources e) the assessment of the participatory learning process and f) the evaluation of satisfaction with the program; 2) the subjects’ knowledge attitudes and behaviors regarding forest conservation at the boundary of Doi Khun Tan before and after the participatory learning process are statistically different at the significance level of .05; and 3) the level of their satisfaction with the participatory learning process was high.

The Purpose of this research was to study the size ratio and structural shape of plus size women determind the standard of dress form and made dress form for plus size women. The representative samples were women’s wears pattern makers students in textiles and clothing field and another related fields which amount 50 persons. The tools of research composed of the questionnaire that evaluated the satisfaction in dress form for plus size women. The statistical analysis were average percentage and standard deviation. The results show that since 1981-2008 the size ratio and structural shape of plus size women in straight shape apple shape pear shape and Hourglass shape had more size ratio in every year. The medium size of plus size women is the beginning shape that is 38. The weight of the woven fabric was 201.90g/sqm; the thickness 0.61mm; the warp size 20.97tex; the weft size 18.44tex; the warp number 44/inch; and the weft number 33/inch. The weight of the knitted fabric was 186.60/sqm; the thickness 0.79mm; the thread size 8.57; the number of vertical loops 35 loops/inch; the number of horizontal loops 30 loops/inch; and the busting strength 179.53lb/inch. It was also found that the satisfaction on dress form for plus size women from woven and knitted fabrics was at the good level with the averages of 4.31 and 4.28.

This study aimed to 1) the evaluation of the design of Local History WebQuest of Mathayomsuksa 1 students based on constructivism through online social network revealed a high level of quality (= 4.62 S.D.=0.35) 2) the participants who studied Local History by using WebQuest with constructivism through online social network for Mathayonsuksa 1 students showed a better learning progress for no less than 20% 3) the participants’ satisfaction toward studying Local History by using WebQuest of Mathayomsuksa 1 students with the model that has been developed reached a maximum ( = 4.57 S.D. = 0.69).
