Although prior knowledge is an important predictor of future performance in mathematics, few studies have analyzed which areas of the subject are most critical. Most evidence is based on small- and medium-scale studies from developed countries, with results that cannot be generalized. We explore which areas of mathematics are the most important…

International comparisons have highlighted that the U.S. mathematics curriculum, both in terms of curriculum influences (e.g., textbooks, standards) and actual instruction, is broad and shallow. Standards-based reform is explicitly designed to improve coherence and reduce redundancy across grades. This article evaluates the redundancy of…

Examined the effects of science curricula organized around topical and causal styles of discourse on 46 eighth graders. Found that students taught with the causal style of discourse had significantly higher retention rates and could better apply their knowledge to problem-solving exercises than students taught with the topical style.

Identified preferred writing topics for 600 students in grades, 4, 6, and 8 and gender markers used to identify authors of 9 stories written by other students. Found that students situated girls' writing within primary territory; viewed girls as more competent, conscientious writers than boys; and associated the presence of violence with male…

Investigated the efficacy of two related reciprocal teaching interventions--with cooperative grouping or with cross-age tutoring--on the reading comprehension of learning disabled English-as-a-Second-Language (ESL) students. Found no significant difference between the two groups: both made comprehension gains and continued to improved when…
