This study examined mathematics and science performance of students who frequently, sometimes or never spoke Persian at home. The data were obtained from 1914 Iranian fourth–grade students who participated in TIMSS 2003. One–way ANOVA and Kruskal–Wallis statistical tests were used to analyze the data. The results showed mathematics and science performance differs significantly among students who frequently, sometimes or never spoke Persian at home. Students who frequently spoke Persian achieved higher scores in both subjects than those who sometimes or never spoke the language at home. In addition, students who sometimes spoke Persian achieved higher scores in both subjects than those who never spoke it. Furthermore, the results indicated that having access to home educational resources, doing homework on mathematics and science, students’ self–confidence in learning mathematics and science were significantly different among the three groups and the differences were in favour of students who frequently and sometimes spoke Persian respectively.

This study, which used a sample of 137,346 students from thirty three countries that participated in the TIMSS 2003 project in the eighth grade, examined the features of the individual and collective relations of three dimensions of mathematics attitude to mathematics achievement (MA), searching for the dimension mostly related to that achievement. The three dimensions of mathematics attitude were self-confidence in learning mathematics (SCLM), liking mathematics (LM) and usefulness of mathematics (UM). By utilizing psychometrically valid and reliable measures of the three dimensions, it was found that: (1) each dimension of mathematics attitude alone was positively related to MA for almost all thirty three countries; (2) SCLM was primarily related to MA for thirty one countries; (3) when the two other dimensions were held constant, SCLM was positively related to MA for thirty three countries, LM was negatively related to MA for thirty countries, whereas UM was not related to MA for twenty one countries; (4) positive collective relationships of SCLM, LM and UM to MA considerably varied from country to country. Implications for research and practice are included.

AbstractThe paper uses data from the combined TIMSS (Trends in International Mathematics and Science Study) and PIRLS (Progress in International Reading Literacy Study) assessment in 2011 to explore the subject-specific strengths and weaknesses among fourth grade students worldwide. Previous research came to the conclusion that students only differed in overall achievement levels and did not exhibit subject-specific strengths and weaknesses. This research did, however, not control for differences in overall performance levels when searching for profile differences. Therefore, the present study uses factor mixture analysis to study qualitatively different performance profiles in mathematics, reading, and science while controlling for differences in performance levels. Our findings suggest that the majority of students do not show pronounced strengths and weaknesses and differ mainly in performance levels across mathematics, reading, and science. At the same time, a smaller share of students does indeed show pronounced subject-specific strengths and weaknesses. This result does not represent an artefact, but we find clear and theory-conforming associations between the identified profiles and covariates. We find evidence for cross-country differences in the frequency of subject-specific strengths and weaknesses and gender differences, as well as differences between students who do not or only sometimes speak the language of test at home.
