NLSMA Reports, No. 13, Patterns of Mathematics Achievement in Grade 9: Y-Population.
Kilpatrick, Jeremy; McLeod, Gordon K.
This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). Further, it is of the subseries that analyzed data for the purpose of identifying differential patterns of mathematics achievement which are correlated with different textbook series. This particular report considers comparisons made for the Y-Population (studies from grades 7 through 11) from achievement test data collected at the end of grade 9 and again at the beginning of grade 10. (NLSMA Reports Nos. 12, 14, 15 cover similar analyses for this population in grades 7 and 8, 10, 11.) Only the two-thirds of the population using a first-year algebra textbook are included in this study. Thirteen measures of mathematical achievement were used as dependent variables and nine significant differences were found after statistically adjusting for initial differences. While this study failed to indicate that any one textbook series was clearly superior, there were different profiles that emerged and these are discussed for each textbook series in the summary.
