This research aims to develop and calculate the efficiency of electronic books injection mold design engineering for Plastic Mold Technology1 (04-812-313) The participants of this research were 40 third year students who enrolled in Plastic Mold Technology1 subjects in first semester 2013. The research tools were 1) an electronic books 2) a questionnaire for measure an efficiency of electronic books 3) an achievement test. Data were analyzed by using difficulty discrimination validity index of consistency The result showed that quality of electronic books injection mold design engineering was in a very good level with higher sufficiency mean = 1.13 than criteria at mean = 1 and was very useful for Plastic Mold Technology1 (04-812-313)

This research aims to solve the basic knowledge problems of undergraduate students who study Calculus 1 for Engineers in the Faculty of Engineering Rajamangala University of Technology Phra Nakhon. Basic Mathematics tutorials are conducted in order to improve their knowledge which leads to increase the efficiency of learning the Calculus 1 for Engineers. The basic mathematics lessons are designed and their efficiency is assessed in the tutored group using the 60/60 criteria. The pretest and posttest are assigned to both tutored and tutorless groups as well as the tutored student satisfactions with thedesigned lessons and the Calculus 1 for Engineers are conducted. The result shows that the efficiency of the designed lessons is 76.60/64.67 which is higher than the criteria; hence they are proper to be used. For the treatment group the posttest grades are higher than the pretest grades significantly (.05) with the effectiveness of 34.67. The comparison of the learning achievement for the Calculus 1 for Engineers shows that the grades of the tutored group are higher than the grades in the tutorless group significantly (.05) as well. The student satisfactions for both the designed lessons and the Calculus 1 for Engineers are at the levels of good and very good.

The research paper is considered as quantitative work which has the following objectives: 1) to study Rajamangala University of Technology Phra Nakhon staffs A Study of behavioral factors associated with the use of online registration via the website.2) to study the relationship between their attitude and behavior towards using the registration system via the website. And 3) The compare problems in the system register online the website. Rajamangala University of Technology Phra Nakhon. The subjects of the study are 51 in-service teaching staff and 349 undergraduate students from 9 faculties. The instruments in this research consisted of questionnaire which the data were analyzed by using percentage mean standard deviation X2 t-test oneway analysis of variance and Scheffe’s method were utilized for data analysis. The results of the study revealed that: 1. The behavioral factors associated were age status and experience of used internet that related with behavior towards using the registration system via the website. In the objective of using the registration system via the website the time and location was statistically significant at 0.05 levels. 2. A good attitude in using the registration system via the online website had related with behavior of using the registration system via the website. The objective and the time of using the registration system via the website were different. 3. The behavioral factors associated were gender status and learning center which had related with different problem in using the registration system via the website.

The purpose of this research was to construct the efficiency of the Computer Assisted Instruction Package for Computer Instructional Package for Drawing 2 Dimension Subject for students in Vocational Certificate Education Level using subject by evaluating the efficiency of the Computer Assisted Instruction Package of the Students to the Computer Assisted Instruction Package for Drawing 2 Dimension Subject with the tools. The sample group was 30 students of Machine Shop Department in Vocational Certificate Education Level Pathumtani Technical College. Analysis by Index of Consistency Level of Difficulty Discrimination Power Average and Computer program. The result of this research was the efficiency 81.14/82.50 higher than the rule of 80/80. This could be concluded that the computer self study packagefor Drawing 2 Dimension Subject using can be used as a learning package efficiently.

The research aims were 1) to develop and find out the efficiencies of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching to be efficient in accordance with defined 80/80 criteria 2) to compare the learning achievement before and after learning of students who studied with the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching and 3) to find out the students’ satisfaction towards the program. A purposive sampling technique was employed to obtain the subjects of this study who were 30 Engineering students of Electrical Engineering Department Faculty of Engineering Rajamanagala University of Technology Pranakhon. They were registered in the second semester of academic year 2013. For instruments were as follows: the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching the evaluation form of the multimedia computer instruction program the students’ achievement tests and the questionnaire of students’ satisfaction. After the experiment the scores obtained from the test were analyzed by using percentage mean standard deviation and t-test. The results of the study showed that the efficiency of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching was 81.22/83.55 which was higher than the specified criteria of 80/80. The scores of after learning with the multimedia computer Instruction program were significantly higher than the scores of before learning at .05 level. And the students revealed that they were highly satisfied with the program.
