The Effect of Math Clubs on Mathematics Achievement and Attitudes Toward Mathematics of Eighth-Grade Females Shonique L. Alexander May 2003 The purpose of this study was to evaluate the effect of math clubs on the mathematics achievement and attitudes toward mathematics of eighth-grade females. Using a quasiexperimental design, the study followed two comparable groups of students through the second and third quarters of the 2002-2003 school year. One group attended math club and another did not. Observations of mathematics achievement and attitudes toward mathematics were obtained by pre and post measures. The experimental group, (n=26), attended an all female math club for six weeks designed by the researcher using a cooperative, hands-on approach to learning mathematics. Analysis using a paired sample t test revealed a significant improvement in the grades of the treatment group following attendance in the math club (t = -3.311, p = .003). These findings suggest that participating in a math club can be a viable approach to improving mathematics achievement and attitudes toward mathematics for females. In addition, the study revealed a non-trivial correlation between mathematics achievement, attitudes toward mathematics, and attending the math club.
