Variables Affecting Science Learning Achievement of Prathom Suksa 6 Students under the Ubon Ratchathani Primary Educational Service Area Office 3

Abstract

The purposes of this study were to : (1) investigate the variables affecting science learning achievement of Prathom Suksa 6; (2) analyze  good predicting variables of their science learning achievement; and (3) construct predicitng equations of their science learning achievement. The samples were 376 Prathom Suksa 6 students in the second semester, academic year 2016. The instruments were three tests with difficulty index of 0.33 to 0.78, discrination power of 0.22 to 0.93, and reliability of 0.82 to 0.88, and four questionnaires with discrimination power of 0.27 to 0.70, and reliability of 0.82 to 0.90. The data were analyzed using multiple regression analysis.      

The research findings were as follows :

1. There was a linear relation at multiple correlation coefficient of 0.66 between science learning achievement and cognitive domain variables, namely : background knowledge, aptitudes toward; and affective domain variables, namely : need for achievement, science learning attitude, self-concept and learning intention.
2. There were two good predicting variables of science learning achievement, namely: learning aptitude (APT), bacground knowledge (BAS), all of which could explain the variance of scienc learning achievement 44%.
3. The predicting equations of science learning written in raw and standard scores were:

Equation in raw scores :  ACH' = 2.37 + .26 (APT) + .40 (BAS)

Equation in standard scores :  Z' _ACH  = .39Z _APT   + .36Z_BAS
