Presents a three-year longitudinal study investigating the development of children's (n=82) understanding of multidigit number concepts and operations in grades one through three by using interview processes. Provides an existence proof that children can invent strategies for adding and subtracting and illustrates both what that invention affords…

Examined changes in beliefs and instruction of (n=21) primary grade teachers over a 4-year period in which the teachers participated in a CGI (Cognitively Guided Instruction) teacher development program that focused on helping teachers understand the development of children's mathematics thinking. (Author/MKR)

Nine different attitude scales are briefly described. They cover attitude toward success in mathematics, mathematics as a male domain, mother's and father's attitude, teachers' attitudes, confidence in learning mathematics, mathematics anxiety, effectance motivation in mathematics, and mathematics usefulness.

Reviewed are studies on differences in mathematical achievement between boys and girls. Studies are sorted into pre-school, early elementary, upper elementary, and high school categories to synthesize the results. A summary is presented in the form of questions which arise from analysis of these studies' results. (JP)

Investigated was how girls and boys who were discrepant in their spatial and verbal performance used spatial visualization skills in solving word problems and fraction problems. It was concluded that low spatial visualization skill may be more debilitating to girls' mathematical problem solving than to boys'. (MNS)

The conclusion that differences in achievement in mathematics between males and females has a genetic basis is seen as based on a number of faulty assumptions. Concern about recent research that can lead to social damage when misquoted and misinterpreted is expressed. (MP)

The evaluation of the intervention program indicated that females in the experimental group increased their knowledge of sex-related differences and actually enrolled in more mathematics courses. (MP)

Addresses two questions: (1) How has gender and mathematics been treated in the "Journal for Research in Mathematics Education" (JRME), and how does that record fit into the broader societal concern with gender and mathematics? (2) What kinds of studies should be published in the future to achieve equity for females in mathematics? (31 references)…
