The purposes of this study were to assess the differential effects of a single strategy (schema-based instruction; SBI) versus multiple strategies (general strategy instruction, GSI) in promoting mathematical problem solving and mathematics achievement as well as to examine the influence of word problem-solving instruction on the development of computational skills. Eighty-eight 3rd graders and their teachers were assigned randomly to conditions (SBI and GSI). Students were pre- and posttested on mathematical problem-solving and computation tests and were posttested on the Pennsylvania System of School Assessment Mathematics test, a criterion-referenced test that measures student attainment of academic standards. Results revealed SBI to be more effective than GSI in enhancing students' mathematical word problem-solving skills at posttest and maintenance. Further, results indicate that the SBI groups' performance exceeded that of the GSI group on the Pennsylvania System of School Assessment measure. On the computation test, both groups made gains over time.

The purpose of the study was to investigate the effects of revising goals focused on content and audience awareness on the persuasive writing of fifth-and eighth-grade students. Students were randomly assigned to three different goal conditions: a general goal; a goal to improve content; and a goal to improve content and communication with an audience. Final drafts of essays were scored for elements of persuasive discourse relevant to content and audience and for overall persuasiveness. Students in the audience goal group were more likely than both other groups to consider opposing positions and rebut them. Students in both the content and audience goal groups wrote essays that were more persuasive than essays by students in the general goal group. The results also indicate that eighthgrade students wrote more persuasively than fifth-grade students and that girls wrote more persuasively than boys.
