Current energy from sun made a significant contribution in the electricity manufacturing industry in Thailand. However the potential application of solar energy are at the low level. The agency will need to make solar energy perpendicular to the sun as much as possible. Therefore the invention of the light experimental set for two-axis motion to identify the vertical axis was done to compare the value of Light Dependent Resistor to locate the origin of the light and can be applied to the real work in the future.

This survey research was conducted to study teaching efficiency as well as comparing the individual factors and opinion on teaching efficiency of student center based on the National Education Act of B.E. 2542 (1999) Faculty of Business Administration Rajmangkala University of Technology Phra Nakhon. The sample taken for the investigation was 400 students who enrolled in the Faculty of Business Administration Rajamangala University of Technology Phra Nakhon for academic year 2010. The study presented the following results. 1. The perspective on teaching efficiency of student center based on the National Education Act of B.E. 2542 (1999) Faculty of Business Administration Rajmangkala University of Technology Phra Nakhon was in a high level. 2. The perspective on teaching efficiency of student center based on the National Education Act of B.E. 2542 (1999) Faculty of Business Administration Rajmangkala University of Technology Phra Nakhon classified by genders had a statistical significance at .05 level. 3. The perspective on teaching efficiency of student center based on the National Education Act of B.E. 2542 (1999) Faculty of Business Administration Rajmangkala University of Technology Phra Nakhon classified by study areas had a statistical significance at .05 level.

The Purposes of this study were 1) to study the efficiency of childcentered approach in the faculty of mass Communication Technology Rajamangala Unuversity of Technology Phra Nakhon 2) to compare personal factors with attitude towards the efficiency of child-centeres approach in the Faculty of Mass Communication TechnologyRajamangala Unuversity of Technology Phra Nakhon 3) to study the progress of learning efficiency after the application of child-centered approach in the Faculty of Mass Communication Technology Rajamangala Unuversity of Technology Phra Nakhon and 4) to study the predicted variablesvariablespersonal factors:genderstudy areasstudent gradeschool record and attitudes towards child-centered approach. The sample taken for the investigation was a number of 300 students in academic year 2009 from the faculty of Mass Communication TechnologyRMUTP. The proportion of 300 students was considered as 50 % of all students studying in the semester 2/2009. The data were collected by questionnaires. The data were analyzed by frequency distributionpercentagemeanstandard deviationt-testF-test One-Way ANOVA and Stepwise multiple regression analysis.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the records management for the standard 90 / 90 and analyze the student learning achievement after using computer assisted instruction. The samples were the 18 Bachelor of Business Administration Program in Management Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the practiced to prepare office equipment in learning next the students did the posttest. After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students learning achievement after studying. The result revealed that the computer assisted instruction efficiency was efficient for standard 90 / 90. And after studying by using computer assisted instruction the students learning achievement increased significantly at 0.05.
