Learning fractions is a critical step in children's mathematical development. However, many children struggle with learning fractions, especially fraction arithmetic. In this article, we propose a general framework for integrating understanding of individual fractions and fraction arithmetic, and we use the framework to generate interventions…

Fourth- and sixth-grade students with and without learning disabilities wrote essays about a controversial topic after receiving either a general persuasion goal or an elaborated goal that included subgoals based on elements of argumentative discourse.

Reports on a study in which students with and without learning disabilities wrote persuasive essays about controversial topics. One group of students was given an elaborated goal that included explicit subgoals based on the elements of argumentation. Sixth-grade students in the elaborated goal condition produced more persuasive essays and included…

Proposes that conceptual and procedural knowledge develop in an iterative fashion and improved problem representation is one mechanism underlying the relations between them. Two experiments were conducted with 5th and 6th grade students learning about decimal fractions. Results indicate conceptual and procedural knowledge do develop, iteratively,…

The effects of a revising goal to "add information" on revising behavior and writing performance were examined for 70 5th and 6th graders. Students assigned the goal made more meaning-based changes and produced improved text quality. Procedural assistance did not appreciably enhance revising behavior or text quality. (SLD)
