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 inBio-organic chemistry and construct the prediction equation models of student,s Bio-organic chemistrylearning achievement in Rajamangala University of Technology Phra Nakhon (RMUTP). The sampleconsisted of 90 students of RMUTP. The instruments were the questionnaire of 5-rated rating scales ofthose 10 categories and 71 items, the reliability of the questionnaire was total average of 0.911. The test of4 choices Bio-organic chemistry learning achievement consisted of 50 items. The level of difficulty wasbetween 0.27 - 0.53, the power of discrimination was between 0.35 - 0.69, The reliability was 0.79. Thedata were analyzed through statistical techniques of percentage, mean, standard deviation and multipleregression analysis.

The results were as follows : The Variables Affecting on student,s Bio-organic chemistry LearningAchievement at .05 level of significant were the Bio-organic chemistry attitude (X1). Achievement motivationin Bio-organic chemistry (X2) predicted at the rate of 15.50 Percent. The raw score prediction equationwas : Y = 9.493 + 2.202 X1 + 0.730 X2. The standard score prediction equation was : ZY = 0.380 ZX1 +0.123 ZX2 .
