Abstract: | Using a structural equation model, this research study investigated the mathematics achievement of 8th grade students in Cyprus enrolled in the year 1994–1995. The model contained 2 exogenous constructs – the educational background of the family and the reinforcement from mother, friends and the individual himself; and 5 endogenous constructs – socioeconomic status (SES), and student attitudes toward mathematics, teaching, school climate, and beliefs related to success in mathematics. The study demonstrated that although attitudes, teaching, and beliefs had direct effect on mathematics outcomes, they were not statistically significant. It was also found that family educational background directly affected SES, attitudes toward mathematics, school climate and beliefs related to success in mathematics. Reinforcement exerted a direct effect on attitudes, teaching and beliefs regarding success. There was also evidence that SES directly affects school climate and that teaching directly affects attitudes toward mathematics. |
