Lietuvos moksleivių matematikos pasiekimus veikiantys faktoriai: PISA duomenų analizė

This study examined whether the exposure to pure mathematics has bigger impact on PISA mathematics literacy scores compared to exposure to applied mathematics in Lithuania. Results suggest that exposure to pure mathematics has a positive and consistent relationship with mathematics literacy score on population level in Lithuania. Five fitted models support the hypothesis: a one unit increase in index of exposure to pure mathematics will increase student mathematics literacy score by 18-27 points. The relationship is resilient even after controlling for students’ socioeconomic status and grade. The hypothesis of the study holds for all sub-areas of mathematics. Estimate of exposure to applied mathematics coefficient was negative in all cases and usually insignificant. The negative relationship of exposure to applied mathematics with mathematics literacy score in Lithuania appear to be “semi-quadratic”: it has a positive relationship with mathematics literacy score, but after a certain level of exposure of applied mathematics index is reached ML score starts to decrease. The analysis of Latvia and Estonia shows that index of exposure to applied mathematics follows similar pattern
