Chemicals management of chemistry laboratories in thailand's higher educational institutions.
The purposes of this research were to study of chemicals management problems in Thailand s higher educational Institutions. It also focused on comparing of problems level of teachers who were different in sex age educational level Institutions and chemistry teaching experience. The sample of this research was 205 chemistry teachers in the Department of Chemistry Faculty of Science from 14 Institutions in Bangkok and in related other areas in Thailand s Higher Educational Institutions. The instruments used in this research were the questionnaire of 5-rated rating scales of those 4 categories. The reliability of the questionnaire was that the storage of chemicals 0.80 the using of chemicals 0.75 the disposal chemicals 0.84 the chemicals hazardous prevention 0.79 with the total average of 0.82. The data were analyzed by Statistical Package for the Social Science for Windows(SPSS for windows). The statistic used was mean standard deviation Hest one-way ANOVA and Tukey HSD of Multiple Comparison Test. The results of the research were: 1. The chemistry teachers had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value at the medium level. 2. The chemistry teachers with differences in sex had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of non-significant differences. 3. The chemistry teachers with differences in age had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of significant differences. 4. The chemistry teachers with differences in educational level had the problems level of the overall average value of significant differences in master educational level with doctoral and post doctoral educational level. 5. The chemistry teachers with differences in Institutions had the problems level of the overall average value of significant differences in old Institutions with Kingmongkok Rajabhat and Rajamangala Universites. 6. The chemistry teachers with differences in chemistry teaching experience had the problems level of the overall average value of significant differences in less than 5 year 5-10 year and.more than 10 year.

Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Courses of Practiced Cutting Sheet Metal.
The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to cutting sheet metals based standard 90 / 90 and analyse the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90 /90. Moreover. after learning achievement At significant level of 0.05

The objective of this paper was to study and development of rice straw paper and development of rice straw paper products-making. Part I. Rice straw paper-making. The bleached and unbleached with 2% HP2(aqJform rice straw fiber was boiled with 2% and 4% NaOH(aq) The 4 treatment was take out container and spread in to thin piece of paper. The 4 treatment were conducted to test physical properties and strength properties on rice straw paper. Part II Rice straw paper products-making. The populations in this research were 16 students and 16 teachers on RIT. Chotiwet Campus to making and evaluate the rice straw paper products. The instrument used in this research were questionnaires about the admission on specifics properties of rice straw paper products and satisfaction to rice straw paper products. The data were analyzed by SPSS program. The statistic used that mean standard deviation one way ANOVA and two way ANOVA. Differences between various groups were tested by Scheffs method.

The questionnaires consisted of 6 learning styles classified by Reichman and Grasha : Independent Dependent Avoidance Collaborative Participant and Competitive consisted of 60 items. The reliability was 0.85. The data were analyzed by using the computer program SPSS for window. The statistics analysis includes a -coefficients percentage mean and standard deviation The results were as follows : 1. Most students occupied collaborative and participant learning styles then independent dependent avoidance and competitive respectively. 2. The competitive and collaborative affecting learning achievement were significantly different at P<05. The competitive learning style has the negative affecting towards learning achievement. The Collaborative learning style has the positive affecting towards learning achievement. 3. The equation used for predicting learning achievement is Y = 2.697 -0.118 X6 +0.158 Xs
