Matematičko samopoimanje: operacionalizacija i empirijska validacija skale

Abstract

Osnovni cilj istraživanja, realizovanog na uzorku 123 učenika prvog razreda gimnazije, bio je konstruisanje psihometrijski validne skale matematičkog selfa na srpskom jeziku. Istraživanje je pokazalo da: (a) konstruisana skala ima dobre metrijske karakteristike U visoku reprezentativnost i pouzdanost i uobičajenu homogenost, (b) varijansu matematičkog samopoimanja (mathematical self) čine dva dela: jedan zasićen hijerarhijski nadređenim elementima globalnog samopoimanja (global self) poput samoefikasnosti (self-efficacy) i intelektualnog samovrednovanja (intellectual self), a drugi zasićen realnim matematičkim postignućem. Relacije matematičkog samopoimanja sa dodirnim konstruktima potvrdile su teorijska očekivanja.

The major objective of this study, which used a sample of 123 ninth- grade Gymnasium (high-school) students, was to construct a psychometrically valid scale of mathematical self-concept in the Serbian language. Its main findings were that: (a) the constructed scale has good metric characteristics - high representativity and reliability and usual homogeneity; (b) the variance of mathematical self-concept is composed of two parts: one saturated with hierarchically superordinate elements of the global self-concept such as self-efficacy and intellectual-self, the other saturated with the real mathematical achievement. The relations of mathematical self-concept with some related constructs have confirmed our theoretical expectations.
