The purposes of this research were to study of Variables Affecting to Learning Achievement in Bio-organic chemistry and construct the prediction equation models ofstudents Bio-organic chemistry Leaming Achievement in Rajamangala University of Technology Phra Nakhon(RMUTP). The sample consisted of60 students ofRMUTP Sampling by Quota Sampling method. The instnunents used in this research were the questionnaire of 5-rated rating scales of those II categories. The reliability of the questionnaire was that the Bio-organic chemistry attitude 0.688 Achievement motivation in Bio-organic chemistry 0.766 Students learning behavior 0.742 Attitude towards University 0.80 I Personality ofchemistry teacher 0.851 Teaching behavior ofchemistry teacher 0.869 Parents support 0.796 University surrounding 0.719 Facilities of University 0.834 with the total average of 0.911 and the test of 4 choices Bio-organic chemistry Learning Achievement consisted of 50 items. The level ofdifficulty was between 0.27 -0.53 the power ofdiscrimination was between 0.35 -0.69 The reliability was 0.79 .The data were analyzed through statistical techniques of percentage mean standard deviation and multiple regression. The results were as follows: The Variables Affecting on students Bio-organic chemistry Learning Achievement at .05 level of significant were the Bio-organic chemistry attitude(xl) Achievement motivation in Bio-organic chemistry (-2) predicted at the rate of 15.50 Percent The raw score prediction equation was : A Y = 9.493 + 2.202 Xl + 0.730 X2 The standard score prediction equation was : A Zy = 0.380 ZXI + 0.123 Zx2

The pupose of this study was to examine The Factors of the Students That Effect To Produce The Graduates of Rajamangala University of Technology Phra Nakhon. The focused on the level of The Factors from students effecting to produce the graduate of the University Tajamangala of Technology Phra Nakhon. The sample 350 students. Data was collected from a set of Questionnaire and analyzed with a statistical software program. The statistical method were percentahe average t-test One-way ANOVA. The level of statistical significance was set at 05 The result indicated that the level of the Factors from students effecting to produce the graduate of Rajamangala University of Technology Phra Nakhon was high. In hypothetical testing the students was influcnced by the following factors ; Age Faculty Leaming Grade of Education. Education before leaming Household Behavior of students Leaming situation and The satisfied of bachelor degree excepted sex and course of study.
