The objectives of this research were to 1) study current situation perceived problems and developmental method of Learner-Centered Teaching-Learning Approach of instructors of Rajamangala University of Technology Phra Nakhon 2) compare the current situation of Learner-Centered Teaching-Learning Approach of instructors classified by faculties and 3) propose developmental method of Learner-Centered Teaching-Learning Approach of instructors of Rajamangala University of Technology Phra Nakhon The sample studied were 257 instructors from all faculties who returned the complete questionnaires to researcher and 2.412 students selected by stratified sampling. The data was collected through questionnaires constructed by researcher. The statistics used for data analysis were mean standard deviation one way analysis of variance and Schffes multiple comparison method. The results were as follows: 1. Learner-centered Teachng-Learning Appoach of instructors of Rajamangala University of Technology Phra Nakhon was at high level (= 3.36). Regarding problems affected learner-Centered Teaching-Learning Approach of instructors it was found that instructors positive attitude toward Learner-Centered Teaching-Learning Approach was at intermedate level and instructors knowledge concerning the Approach was also at intemediate level. moreover it was found that instruclors possessed problems in relation to facilitate faclors of Learner-centered Teaching-learning Approach at intermediate level. 2. Instructors from different facuities had statistically difference of Learner-Centered Teaching-Learning Approach with a level of .01 significarce. 3. The significance of Learrer-Centered Teaching-Learning Approach should be stressed. In additon the better understanding of Learner-Centered Teaching-Leaming techiques should be trained to all instructors Besides the students should be encouraged to study from outside resources more and more.

The purpose to this research was to assessment the graduate Diploma Program of Teaching Profession at Rajamangala University of Technology Phra Nakhon Faculty of Industrial Education of the curriculum used. Research population consisted of graduate students diploma degree graduate their superiors and instructors. Simple random sampling gave the sample size of 549 people were selected from purposive sampling. The research tools were a questionnaire and a focus group discussion recording form. Data analysis employed basic statistics of frequency mean and percentage including content analysis for qualitative data. The findings of this research were as follows: 1) Primary components of the curriculum were suitable at high level. 2) Course structure and content was suitable at high level. 3) Characteristics of lecturers were suitable at high level.4) Instructional and evaluation activities were suitable at high level. 5) Factors contributing to the teaching of the course were also found suitable at high level. On the contrary Journals related to inadequate service and problems of withdrawal teaching materials. However the curriculum development should be updated to suit the needs of society and science is always developing.

This research studies the potential for using waste ash from industrial and agricultural by–products as a geopolymer material. This paper presents a study of the resistance to chloride penetration and resistance to sulfuric acid of geopolymer mortar containing ground rice husk ash (RA) and ground bagasse ash (BA). Geopolymer mortars with constant liquid to ash ratio and similar flow were used for the tests. Compressive strength porosity chloride penetration test Rapid migration test of chloride depth chloride ion diffusion coefficient immersion test of chloride depth and weight loss with impressed sulfuric acid were investigated. Test results show that the workable flow of geopolymer mortar was in the range of 110–115% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH. Extra water was used to improve the workabililty. In case of rice husk ash geopolymer mortar the geopolymer mortars with high strengths were obtained with concentration of NaOH of 15M with the sodium silicate to NaOH ratio by weight of 2.5. However the bagasee ash geopolymer mortars with high strengths were obtained with concentration of NaOH of 10M with the sodium silicate to NaOH ratio by weight of 2.5. The use of rice husk ash and bagasse ash produces geopolymer mixes with good strength and resistance to acid and chloride penetration. The resistance to acid and chloride penetration is higher with an increase in the sodium silicate to NaOH ratio by weight of 2.5.

This paper is a survey research. The objective is to study the factors of Social Adjustment of Technical Education Faculty Students B.S. of Technical Education (5 years curriculum) Faculty of the industrial education Rajamangala University of Technology Phra Nakhon. The random sampling is conducted within the full-time students from 3 majors. The random sampling technique in this paper is derived from Krehbiel-Morgan table. The total number of sample is 167 students. Research Methodology This paper uses the survey method to collect the data. The data analysis process is based on the average percentage value of standard deviation and t-test F-test techniques. The research results can be summarized as follows: 1. Students with different genders have overall social adjustment ability indifferently. 2. Students with different ages have overall social adjustment indifferently. This implies that age is not a factor in social adjustment. 3. Students who graduated from different curriculum have overall social adjustment ability differently. The students who graduated from vocational-qualification curriculum have overall social adjustment ability higher than students who graduated from academic-qualification curriculum. In specific aspect of social adjustment to classmate the result is also the same. 4. Students with different sequence of birth have overall social adjustment ability indifferently. 5. Students with different family status in society have overall social adjustment ability indifferently. 6. Students with their parents in different occupation have overall social adjustment ability indifferently. 7. Students with different average-income-per-month families have overall social adjustment ability indifferently. However in specific aspect of social adjustment to general person the students with higher average-income-per-month families have social adjustment ability better than the students with lower average-income-per-month families. 8. Students with different family characteristics have overall social adjustment ability differently. The students with large family have overall social adjustment ability higher than students with small family.

Purposes of the research were to design and develop Computer Instruction Package on Principle of Object-Oriented Programming and to find out efficiencies effectiveness and leamers satisfaction towards the package. The research tools were: 1) The Computer Instruction Package on Principle of Object-Orientes programming 2) Achievement tests 3) Quality assessment and evaluation form for multimedia software and 4) questionnaire of leamers satisfaction. sampling groups composed of 30 Bachelor first year students from Faculty of Business Administration Program Computer Infomation-Business Computer Rajamangala University of Technology Phra Nakhon. Research results revealed that the efticiency of the Computer Instruction Package was at 81.08/81.05 corresponding with 80/80 criteria. Analysis of pre-test and post-test scores found that the effectiveness aftce the process (E) was at 81.08 it was higher than before the proecss (E) which was at 18.25. Therefore the Computer Instruction Package on Program Design and Development could increase the students learning effectiveness up to 62.83 corresponding with 60 criteria. Mean of satisfaction of the sampling groups was rathe at a high level (4.31). It could be concluded that the Computer Instruction Package on Principle of Object-Oriented Programming had the efficiency that could used for self study.
