Purpose of this study 1) factors affecting the drop out of Rajamangala University of Technology PhraNakhon students in 2014 academic year. 2) correlation with personal information and 3) solutions to prevent the drop out. A study population are 1179 students who have dropped out in 2014 academic year and 584 lecturers of the Rajamangala University of Technology PhraNakhon. The analysis on the students population will be carried out by computing frequency percentage and Chi-square test to observe independency between the two variables. Also conducting an interview on the 360 students and 70 lecturers of the Rajamangala University of Technology PhraNakhon. From data collecting found that majority of student population status can be put by order as terminated deprived and resigned. Gender hometown occupation of parents/guardians and income of parents/guardians show significant relation to the drop out of the students in 2014 academic year while parents marriage status show no relation with statistically significant of 0.05. From the interview it can be extracted and put in order of contribution that personal issue family issue university environment and lecturer effect the student decision to drop out. Suggested solution: the university should create unique image encourage students to have part-time job during semester set up a consulting and support center provide more financial aid adjust and improve university scenery sourcing/maintenance furniture and equipments to meet usage adequate and quality standard and finally set up a colloquiums focusing a practical application. Therefore Rajamangala University of Technology Phra Nakhon should put the result from this study into practical use as a guideline to meet future circumstance and to develop administrative strategy for maximum advantage in the competition.

This applied research want to study the factors affecting the student‘ learning achievement instudying Data Structure and Algorithm. The samples were selected by stratified random sampling 93 students from 121 students who studied in semester 2/2009 by using questionnaire. The statistics used were descriptive statisticst-testOne way ANOVAPearson correlation and multiple regression at the significance level of 0.05. The findings revealed that the mean of grade point average was 2.69 their average midterm scores were 22.47 out of 35. The successful were grade point averagefair expectation of knowledgeand future application.The factors affecting student’s achievementwere basic knowledge of programmingmidterm scores studied resource and facilities. In addition the 2 year programme’ average midterm scores were higher than the 4 year programme ranging from 1.11 to 5.34 at the significance level of 0.05. The forecasting equation for learning achievement is

This research were to study learning behavior and the relationship between learning behavior and academic achievement of students in taxation. The samples were students who studying management at the faculty of Business Administration and Liberal Art at RMUTL-Nan. The instruments for collecting data were behavior observation and tests. The statistical methods for analyzing data were mean and Pearson Product-Moment Correlation Coefficient. The results showed that the students’ learning behavior in taxation was at good level but the average achievement was moderate score: 63.81 out of 100 scores (C). The students’ learning behavior of five domains found that the intention of punctuality timely attention responsibility and attendance were good. Their understanding behavior was moderate. There was positive statistically significant relationship between learning behaviors and academic achievement of students in taxation at 0.01 levels. The correlation coefficient was 0.703.The learning behaviors could predict the academic achievement as 49.40 percent.

The purposes of this research were 1) to construct and evaluate the efficiency of the Computer Assisted Instruction (CAI) on Nuclear Physics class to have 80:80 effectiveness standards. 2) to compare learning achievement between pre-test and post-test scores after using the CAI 3) to study student’s opinion about CAI. Samples were the second year of Science and Technology students of the Rajamangala University of Technology Thanyaburi in 2011 academic year selected by simple random sampling. The first test was done by one-to-one evaluation and the second one by a small group in order to revise the CAI before implementing within the subject. The efficiency of the CAI was evaluated by experts both in content and production technique of the courseware. The results of this research were shown : 1) the CAI on Nuclear Physics contained the effectiveness at 87.00:85.33 which was higher than the standard criterion set (80:80) 2) the comparison between pre-test and post-test was found that the post-test score of students who studies with CAI were significantly higher than the pre-test score at .05 level and 3) the mean score of the student’s opinion about CAI was 4.35 shown that most of them satisfied the CAI on Nuclear Physics at good level.

The purposes of this research aimed to 1) develop the instructional packages namely Vector Quantities and 2) compare the achievement scores of the experimental group and the control group. The samples were 60 Computer Science students of Faculty of Science and Technology at Rajamangala University of Technology Phra Nakhon who took Principle of Physics course in semester 1 academic year 2013. They were purposely selected as an experimental group (30 students) and a control group (30 students). They were given two different treatments ; teaching with the instructional packages and the conventional teaching. The research instruments for the experimental group were the instructional packages comprised lesson plans instructional documents and instructional media whereas the control group was taught with only instructional documents. After of the experimental process both of them were given exercises and teacher’s feedback. Then they were tested to see their achievement. The test was 20 multiple choice items which had the degree of difficulty between 0.33-0.77 the degree of discrimination between 0.30-0.77 and the degree of reliability coefficient at 0.73. The analysis of data comprised 2 parts as follows: 1. The development of instructional packages was evaluated by using statistics One – Sample t -test on Vector quantities Demonstration and using statics in terms of mean on the lesson plans instructional documents and instructional media . 2. The achievement scores were evaluated by using t-test at the level of 0.5. The results of this research revealed that : 1. The quality of the instructional packages was excellent. 2. The achievement scores of the students who studied with the instructional packages were higher than those of the control group at the level of .05
