Assessment of general reasoning processes, elementary algebraic understanding, and novel problem solving of (n=147) seventh- and eighth-grade students found that abilities to generalize from patterns and tables of data and understanding variable constructs contributed significantly to application of algebraic concepts and processes. Questions…

Describes a project in which students, in groups, wrote a chapter on factoring polynomials. Gives general format of the activity and excerpts from student writings. (10 references) (MKR)

Describes the underlying philosophical and cultural changes associated with classroom organizational changes in one eighth-grade teacher's attempts to implement National Council of Teachers of Mathematics standards. Observations and interviews indicated that there were two distinct cultures ("book world" and organic or…

The focus of this paper is to further understanding of the distribution and the effects of an expanded conception of opportunity to learn on student mathematics achievement. In addition to descriptive statistics, a set of two-level hierarchical linear models was employed to analyze a subset of the restricted-use National Education Longitudinal…
