The purpose of this research is to study and compare several factors which can influence how first year students make their decisions to study in Rajamangala University of Technology Phra Nakhon. The samples were about 370 students which were collected by Quota Sampling. Questionnaires were used as a research tool to collect data. The data were analyzed by percentage arithmetic mean standard deviation t-test F-test and LSD. This research found that 1. Most of students are female and have graduated from high school with GPA of 3.09. They study in the faculty of business administration. Their hometown is in Bangkok and perimeter. Their parents are business owner and have average income about 21950.88 bath per month. They spend money about 148.66 bath per day. 2. Mostly the students have decided to study in Rajamangala University of Technology Phra Nakhon by themselves and have chosen not to apply in other universities. In addition they have known about admission from the internet. 3. The universitys reputation is a main factor that students use to consider in order to study in Rajamangala University of Technology Phra Nakhon. Other factors that have less influence are curriculum students requirement lecturer universitys administration financial support transportation location and environment respectively.

This research comparatively concludes that different factors have influenced students to enroll in Rajamangala University of Technology Phra Nakhon in many different levels with statistical significance at 0.05 level. 5. The students with different genders GPA education backgrounds howntowns parents income and daily expense have various levels of factor that affects students decision making for enrollment with no statistical significance at 0.05 level. 6. The students with different faculties and alternatives to apply in other universities have different levels of factor that affects their decision to enroll in Rajamangala University of Technology Phra Nakhon with statistical significance at 0.05 level.

The purpose of this research were to develop the efficiency of Computer Assisted Instruction (CAI) in Bio – Organic chemistry and to compare the leaming achievement in Bio – Organic chemistry the sample consisted of 35 and 39 student in Department of Food and Nutrition Faculty of Home Economic Technology Ragamangala University of Technology Phra Nokhon 2008 academic year. Research instrument were the CAI and Achievement test in Bio – Organic Chemistry in Carbohydrate. The achievement test comprised 40 item. The data analyzed by statistical computer program. And used mean percentage and compare mean by t-test

The purpose of this study was to study the some factors related to attitude in environmental pollutions of students and compare attitude in environmental pollutions of students in faculty of business administration at Rajamangala University of Technology in Bangkok in 6 aspects : environmental pollutions water pollution air pollution noise Pollution toxic substances pollution and solid waste pollution. The students were classified by gender academic years and major subjects. The samples in this research were 1745 students. The study participates were selected by stratified random sampling. The 30 item tests and 42 item questionnaires of Likerts rating scales were used as the research instrument. Percentage mean standard deviation t -test for independent sample F -test LSD analysis and multiple correlation (stepwise multiple regression analysis) were statistical methods to analyze data. The results were as follows: 1.Attitude in environmental pollutions of students all aspects were in agreeable levels that noise pollution was the highest while environmental pollutions and water pollution was in the lowest rank. 2.Media exposure about environmental pollutions of students were in middle level that friend and television was the highest. 3. There was significant difference for media exposure about environmental pollutions at the 0.05 level among students in different gender and different major subjects. 4. There was significant difference for knowledge about environmental pollutions at the 0.05 level among students in different gender different academic years and different major subjects. 5. There was significant difference for attitude in environmental pollutions at the 0.05 level among students in different gender different academic years and different major subjects. 6. The score -weight of knowledge about environmental pollutions and media exposure about environmental pollutions contributed to attitude in environmental pollutions of students with statistically significant at 0.01 level and then media exposure about environmental pollutions contributed to attitude in environmental pollutions of students higher than knowledge about environmental pollutions.

The purpose of the research was first to study the need of information technology application in second to study the types of information technology services that is effectively corresponding to the need of users. The third is to study information technology application in cassroom teaching and the last forth is to apply all these strategies to Rajamangala University orf technology phra Nakhon. In the research the examined population was both academic staffs and students of Rajamangala Univessity of Technology Phra Nakhon. Their samping mumbers selected from all 9 faculties were total 1506 peoplecounted of 80.97 percentages. The research tool used was questionnaires in order to engaging the effectiveness and the need of basic factor of information technology. For the data analysis one=way analsis of variance (ANOVA) approach was chosen for the study. In this study the results showed that most staffs thought it had majior effectiveness of information technology mangement with a mean value off 3.475 whereas most students though it was medium effectiveness with a mean value 3.393. For the needs of information technology most staffs considered it a hight range of an average at 4.420 while the students believed its importance with an average of 3.686. Besides for this same need both staffs and students from various facultes had same major opinons that there was no difference at the statistic significant level of 0.05

The development of Computer-assisted Learning Program to rectify the weakness of third year students of Rajamangala Institute of Technology Bangkok Commercial Campus on the concept of mathematics polynomial factor. Mathematics can develop student thinking in system reason have effective problem solving and can use for other tool subject but effective lesson on mathematics to leave media with admire media is Computer-Assisted Instruction. The purpose of this experimental research was to develop the efficiently mathematics computer assisted instruction with the effectiveness of 80180 and to compare learning achievement on polynomial factor to pre and post test in computer-assisted instruction to rectify the weakness of basic mathematics of the third year students of Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus in the first semester of the 2006 academic year of two 60 students groups with specify experiment one 39 students group. The findings of this study revealed that the computer assisted instruction to rectify the weakness of Mathematics Polynomial Factor had the effectiveness of EIE2= 80.89/81.58 which higher than 80/80 criterion and the students who were learned with Mathematics Polynomial Factor got significantly increased at the 0.05 level.
