Brief Note: A Comparison of How Textbooks Teach Mathematical Problem Solving in Japan and the United States
When Politics Took the Place of Inquiry: A Response to the National Mathematics Advisory Panel's Review of Instructional Practices
The National Mathematics Advisory Panel was given the task of reviewing research on the instructional practices that enable students to learn mathematics successfully. The authors argue that in conducting its review, which appears in Foundations for Success: The Final Report of the National Mathematics Advisory Panel (2008), the Panel imposed dangerous dichotomies, opposing extreme forms of teaching against one another. Such dichotomies bear little relation to the realities of mathematics classrooms in the United States and belie the research that has been conducted in mathematics education in the past 20 years. In addition, the methodological restrictions imposed by the Panel rendered the field of mathematics education virtually invisible
Review and “Vote Count” Analysis of OTL-Effect Studies
In the fourth chapter an overview is given of 51 primary studies, conducted during the last twenty years. Schematic summary descriptions are put together in a large summary table. Although quantitative meta-analysis of these studies was beyond the scope of this review study, some basic summary tables were produced to provide an overall orientation on how OTL had been researched and what can be concluded about its effectiveness. It is concluded that the vote count measure of OTL, (i.e. the percentage of effect sizes that were statistically significant and positive) established in this study, and which was 44 %, is of comparable size to other effectiveness enhancing conditions like achievement orientation, learning time and parental involvement, but dramatically higher than vote count measures for variables like cooperation and educational leadership. What should be considered is that vote counting is a rather crude procedure and that comparison of quantitative effect sizes is more informative
