The purposes of this research were to design contents build both document-based and electronic-based teaching materials and find out the students’ satisfaction towards the use of ASEAN Economic Community related lessons for English writing courses. The sample group consisted of two 30-student sections of totally 60 third-year undergraduate students majoring in English for International Communication faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. After they had tried using the lessons did the document-based exercises answered the first questionnaire tried the electronic-based exercises and answered the second questionnaire their data were analyzed and revealed as follows. 1. The analysis of the first questionnaire revealed that the students’ average satisfaction towards the English writing content lessons was in the highly middle level with 3.15 out of 5 points or 63 per cent. 2. The analysis of the first questionnaire also revealed that the students’ average satisfaction towards the English writing document-based exercises was again in the highly middle level with 3.38 out of 5 points or 67.67 per cent. 3. The analysis of the second questionnaire revealed that the students’ average satisfaction towards the English writing electronic-based exercises was in the high level with 3.65 out of 5 points or 72.98 per cent. In comparison there was a difference of 0.27 points or 5.31 per cent between the students’ satisfaction towards the electronic-based exercises and that towards the document-based exercises implying that the students preferred the electronic-based exercises to the document-based exercises.

This research studies the potential for using waste ash from industrial and agricultural by-products as a plastering material. This paper presents a study of the water requirement compressive strength flexural strength normal consistency setting time and air content of plastering material containing classified fly ash (FA) and ground rice husk ash (RHA). Fine fly ash and fine rice husk ash have a high potential to be used as a good pozzolanic material. The use of finer pozzolan results in a stronger and denser mortar which is due to better Q!spersion and filling effect as well as an increase in the pozzolanic reaction. Fine fly ash and fine rice husk ash can be incorporated into mortar as replacement of the mortar mix cement for the plastering. Mortar mix cement containing 20% fine fly ash and fine rice husk ash can be used to make plastering materials.

The objectives of the research werw 1)to study the creative level of Prathomsuksa 5 students who take constructivism learning 2)to com[pare the creativity of Prathomsuksa 5 students learning of the constructivism form with those learning of the normal form 3)to study the satisfactions towards learning in accordance with the constructivism form of Prathomsuksa 5

The objective of this research is to study the implementing the agricultural residue to the design of outdoor paving block for lowering the building temperature. The base layer admixture (layer no.1) is selected from cement type1: quarry dust: rice husk: rice straw: water ratios equal to 1: 3: 0: 0: 0.3 1: 1: 0: 1: 0.5 1: 1. 0.25: 0.75: 0.5 1: 1: 0.5: 0.5: 0.5 1: 1: 0.75: 0.25: 0.5 and 1: 1: 1: 0: 0.5 by weight. The surface layer admixture (layer no.2) is white silica cement: yellow stone chip no.4: water equals to 1: 4: 0.3 by weight. The exterior floor-covering blocks were tested following density testing water absorption testing compressive testing and surface temperature testing compare with laterite sandstone paving concrete block marble and granite. Resulting the best ratio of cement type1: quarry dust: rice husk: rice straw: water is 1: 1: 0.75: 0.25: 0.5 that has properties at 28 days following 1939.43 kg/m of density 14.97 % of water absorption 284.69 ksc of compressive strength and lower than other paving blocks around 3 – 13 degrees Celsius of surface temperature

The purposes of the research were to create and efficiency validation of computer Assisted for the courses of practiced to reading Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program Subject Engineering Materials Chapter 3-6 based standard and analyses the leaning achievement of the student after by using computer assisted instruction . The subjects in the study were 20. 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 analyzed the learning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard Moreover after learning achievement at significant level of 0.05.
