Examine with us how students “understand fractions as numbers” and “view fractions ” as being built out of unit fractions”—two emphases of CCSSM.

An understanding of fractions eludes many U.S. students. This randomized trial of lesson study supported by mathematical resources assigned 39 educator teams across the United States to locally managed lesson study supported by a fractions lesson study resource kit or to 1 of 2 control conditions. Results suggest that integrating research-based res...

Purpose – The purpose of this paper is to describe the design and initial implementation of a lesson study network in the US intended to support implementation of the Common Core State Standards (CCSS). Design/methodology/approach – Participant observation and artifact collection document the development of the teaching through problem solving (TT...

The authors comment on the article by Morris and Hiebert in three ways. First, they add thoughts about why improvement efforts often focus on teachers, rather than teaching. Second, they offer evidence from U.S. lesson study research that focus on teaching can improve both students’ learning and teachers’ learning. Finally, they suggest that the in...

Two hundred thirteen teachers and 1,059 students from 27 U.S. school districts participated in a randomized controlled trial of lesson study, with or without a resource kit on fractions. Lesson study is a form of professional learning in which teachers collaborate to study the academic content of the curriculum and to conduct cycles of inquiry focu...

In lesson study, teachers engage in cycles of inquiry in which they collaboratively plan, observe, and discuss classroom lessons. In addition to improving the teaching of a particular topic, lesson study is designed to build the skills, habits of mind, tools, and culture for teachers to learn daily from colleagues, students, and curriculum material...

Lesson study (jugyou kenkyuu) has spread outside Japan in the last decade, providing opportunities to see how lesson study fares in countries where the instructional practices and curriculum materials differ from those in Japan. This study reports an elementary mathematics lesson study cycle from the United States. To investigate the nature of the...

This article presents a theoretical model of lesson study, an approach to instructional improvement that originated in Japan. The theoretical model includes four lesson study features (investigation, planning, research lesson, and reflection) and three pathways through which lesson study improves instruction: changes in teachers’ knowledge and beli...

Abstract Lesson study is a widespread,form of professional development,in Japan that has recently emerged,in a number,of U.S. sites. This paper describes a collaboration,between,researchers and practitioners at one U.S. lesson study site. The collaboration,had simultaneous,goals of building lesson study in one school district; documenting the imple...

This paper features a case study of one US K-8 school district pioneering the use of “lesson study,” a teacher professional development approach adapted from Japan. The case explores events that occurred in the district over more than 4years (Spring 2000–Fall 2004) as lesson study spread nationally and within the district. We document four categori...

Lesson study, a Japanese form of professional development that centers on collaborative study of live classroom lessons, has spread rapidly in the United States since 1999. Drawing on examples of Japanese and U.S. lesson study, we propose that three types of research are needed if lesson study is to avoid the fate of so many other once-promising re...

Lesson study requires teachers to discuss the essential concepts that the students need to learn, compare the concepts with curriculums and consider the present knowledge of students. The various examples and experiences of teachers performing lesson study are presented.

During "lesson study" teachers formulate long-term goals for student learning and development, collaboratively work on "research lessons" to bring these goals to life, document and discuss student responses to these lessons, and revise the lessons in response to student learning. This document summarizes the content of a symposium to discuss the re...

This report describes how lesson study is being implemented in one Northern California school district, drawing on research conducted in the district over 3 years via interviews with project leaders and participants; videotapes/audiotapes of the lesson study work (e.g., planning, research lessons, and lesson colloquia); workshops designed to build...
