There is no doubt that a lesson plan is a necessary product of Lesson Study. However, the collaborative work among teachers that goes into creating that lesson plan is largely under-appreciated by non-Japanese adopters of Lesson Study, possibly because the effort involved is invisible to outsiders, with our attention going to its most visible…

This volume, a comprehensive survey and critical analysis of today's issues in mathematics education, distills research to build knowledge and capacity in the field. The compendium is a valuable new resource that provides the most comprehensive evidence about what is known about research in mathematics education. The 38 chapters present five…

This protocol guided the review of research that informed the recommendations contained in the What Works Clearinghouse (WWC) practice guide "Improving Mathematical Problem Solving in Grades 4 through 8," published in May 2012. The research review involved the following steps: (1) The research staff searched the professional literature…

In quoting Ivan Illich's observation that "people who have been schooled down to size let unmeasured experience slip out of their hands," the author of this article contends that this is what is happening in education --- that we are being assimilated and schooled "down to size." Unmeasured experience, he says, is slipping out of our hands as a…

This report summarizes results from research aimed at improving the quality of information collected about school curriculum. The research sought to design and pilot a model for collecting benchmark data on school coursework. These more indepth data, such as course textbooks, assignments, exams, and teacher logs, can serve as anchors against which…

This paper reports on an experiment designed to investigate the effect of structural and linguistic variables on level of difficulty in solving arithmetic word problems. Identification of such variables is intended to assist curriculum writers in preparing exercises at a specified level of difficulty for students at various age levels. The study…

This article summarizes the findings of the National Research Council (NRC) report "On Evaluating Curricular Effectiveness" and examines the reviews in middle grades mathematics undertaken by the What Works Clearinghouse (WWC). The NRC report reviewed and assessed 147 key evaluations of 13 National Science Foundation-supported K-12 mathematics…

This guide, which is designed to be used in a two-course sequence, is intended to prepare college-bound high school juniors and seniors for engineering and related courses at the college level. The guide was developed as part of an experimental competency-based curriculum that integrates the high-tech applications of mathematics and science…
