Family and motivation effects on mathematics achievement: Analyses of students in 41 countries

This study examines family and motivation effects on student mathematics achievement across 41 countries. The Rasch estimates of PISA mathematics test scores and questionnaire responses of 107,975 15-year-old students were analyzed via multilevel analyses. Students scored higher in richer or more egalitarian countries; when living with two parents, without grandparents, with fewer siblings (especially fewer older siblings); with higher family SES, more books, cultural possessions, or cultural communication; or when they had greater interest in mathematics, more effort and perseverance, and higher self-efficacy or self-concept. Family structure effects were stronger in individualistic or richer countries. Richer countries showed stronger family cultural communication effects, suggesting stronger, intangible resource effects. (C) 2007 Elsevier Ltd. All rights reserved.
