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. Key words: Mathematics; performance; Persian; science; students; TIMSS

The purpose of this study was to simultaneously examine relationships between teacher quality and instructional time and mathematics and science achievement of 8th grade cohorts in 18 advanced and developing economies. In addition, the study examined changes in mathematics and science performance across the two groups of economies over time using data from the TIMSS 1995-2007 assessments. While economy did not account for variation in mathematics and science achievement, findings from regression analyses indicated significant relationships between school inputs and achievement in both groups of countries across the years. Teaching experience was a strong indicator of mathematics performance in developing countries, while instructional time was mildly related to achievement in both subjects in advanced economies.
