Variables affecting to learning achievement in Bio-organic chemistry of students on Rajamangala University of Technology Phra Nakhon

Abstract

The purposes of this research were to study of Variables Affecting to Learning Achievement in Bio-organic chemistry and construct the prediction equation models ofstudent's 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 Parent's 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 student's 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
