This research aims to construct and evaluate efficiency of experiment set for work-piece analysis based on variety of cutting edge parameters of punch-die. The parameters included clearance punch shape and inclination of punch edge that related to cutting force error in diameter and deformation of work-piece. The developed experimental set was evaluated by 15 experts using 5-point scale questionnaire which was divided into two parts: content and worksheet and experiment set design. The efficiency evaluation was done by using the experiment set to teach a sample group of 15 students. Results showed that quality of the proposed experiment set was in the highest level with average score of 4.65 (SD = 0.47). The efficiency evaluation by teaching a sample student group revealed that the efficiency was 85.43/84.00 which was higher than the criteria of 80/80 in research hypothesis. Therefore it can be concluded that the constructed experiment set could be used to enhance students’ analytical thinking in punch-die work.

The shrinkage depended on the product shape and the type of plastic used in injection melting temperature injection speed holding pressure and mold cooling. Different surroundings during the injection resulted in differences shrinkage so the exact shrinkage value hadn’t been known. This was the cause of Try out and error work that produced Injection products that were not in correct size. This research aims to find the shrinkage percentage based on the ASTM D955 standard test method from high density polyethylene (HDPE) which has partial crystalline structure and high shrinkage. The results were as follows: The specimen size 60x60 mm shrinkage was at 2.57 percentage and with 2 mm thickness the shrinkage was 3.60 percentage. The specimen size 12.7x127 mm shrinkage was between 2.76 percentage and 2.91 percentage with 3.20 mm thickness the shrinkage was 2.48 percentage. For the 100 mm circular specimen the shrinkage was from 4.35 to 4.39 percentage and with 3.20 mm thickness the shrinkage was 2.56 percentage

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 purpose of this research was to assess the knowledge and understanding utilization and satisfaction of students toward learning activities in flower arrangement subject. The research sample was 93 of the first year students majoring in Home Economics Business Administration and studying the flower arrangement subject in the second semester of the academic year 2013. The research methodology was the rating scale questionnaire. Data were processed and analyzed by frequency percentage and mean. For the assessment of the students’ knowledge and understanding toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.90. For the knowledge it was at the high level with the mean of 3.82. For the ethics and moral it was at the high level with the mean of 3.79. For the cognitive skill it was at the high level with the mean of 3.78. For the interpersonal skill and responsibility it was at the high level with the mean of 3.70. For the psychomotor skill it was at the medium level with the mean of 3.42. For the assessment of the students’ utilization toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the interpersonal skill and responsibility it was at the high level with the mean of 4.20. For the knowledge it was at the high level with the mean of 3.92. For the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.84. For the ethics moral and it was at the high level with the mean of 3.77. For the psychomotor skill it was at the high level with the mean of 3.66. For the cognitive skill it was at the medium level with the mean of 3.44. For the assessment of the students’ satisfaction toward learning activities based on Thailand Qualifications Framework in flower arrangement subject it was found that for the interpersonal skill and responsibility and the ethics and moral it was at the high level with the mean of 3.98. For the knowledge it was at the high level with the mean of 3.81. For the numerical analysis skills communication and information technology skills it was at the high level with the mean of 3.72. For the cognitive skill it was at the high level with the mean of 3.56. For the psychomotor skill it was at the medium level with the mean of 3.52.

This paper aimed to study and compare awareness of impacts on global warming that are relevant to home economics knowledge base on Home Economics Program Suan Dusit Rajabhat University considering gender and year of study. The sample was bachelor home economics students of every year of Suan Dusit Rajabhat University. Questionnaires were used to the data from 254 samples. The statistics used were frequency distribution percentage average and standard deviation. The hypothesis test made in the study was t-test for independent samples and One Way ANOVA.
