3. How I encountered lesson study….

4. Good professional learning is_____________

5. Lesson Study Cycle 1. STUDY CURRICULUM & FORMULATE GOALS Consider long-term goals for student learning and development Study subject matter, curriculum and standards, focus the inquiry 2. PLAN Select or revise research lesson Write instructional plan that includes: Long-term goals Anticipated student thinking Data collection plan How the lesson fits in the long-term learning trajectory Rationale for chosen approach 3. DO RESEARCH LESSON One team member conducts research lesson, others observe and collect data 4. REFLECT Formal lesson colloquium in which observers: Share data from lesson Use the data to illuminate student learning, disciplinary content, lesson and unit design, and broader issues in teaching-learning Document the cycle, to consolidate and carry forward learning and new questions into next cycle of lesson study

6. “Build children’s mathematical curiosity, and their ability to notice and represent mathematical patterns…” What qualities would you like students to have when they leave your mathematics program? What is a gap between those ideal qualities and their actual qualities that you would really like to work on as an educator? Choosing a Lesson Study Theme

7. Can patterns help us find an easy way to answer the question: How many seats fit around any number of triangles, arranged in a row as shown?

9. INPUT Number of Triangle Tables OUTPUT Number of Seats 13 24 3 4 5 6

10. Questions About Video 1. Planning: What is similar and different from planning familiar to you? 1. Lesson: Practice collecting data on students. 1. Discussion: What do teachers learn? What agenda helps them learn?

11. Research Lesson 1 All students filled out chart correctly but few could verbalize meaning of +2 pattern Research Lesson 2 Chart eliminated, students solved individual problems, shared findings Students showed their counting methods Many students could verbalize meaning of +2 pattern Recap of “How Many Seats?” Lesson Study Cycle

12. Area of circle Area of rectangle Part of a set Linear measurement 1 meter

14. Linear Measurement Context How Can We Describe the Blue Mystery Piece in Terms of One Meter?

15. Common Challenges in Understanding Fractions Seeing fraction as number (“I can’t put 2/3 on number line because it’s two different numbers”) Understanding the magnitude of the denominator (that 1/6 is smaller than 1/5) Knowing what is the whole (construct whole from a fraction) Seeing that fractions can be greater than one

16. How Linear Measurement Context Might Help Length helps students attend to magnitude of fractions (how much) rather than just count pieces (how many) 1 meter

17. Understanding Meaning of Denominator Only 1 dimension (length) varies, making it easier to see that ½ is bigger than ¼ 1 meter

18. Understanding the Whole Standard measurement unit gives clear, stable image of the “whole” 1 meter

19. Understanding 4/3 as 4 1/3’s Length may support multiplicative image that 3 times 1/3 meter is 1 meter and x times 1/n meter is x/n meter meter

20. Lesson Study Resource Kit 1.Mathematics tasks to solve and discuss (& related student work to analyze) 2.Curriculum inquiry: Japanese textbook, Takahashi lesson video, teachers’ materials 3.Lesson study materials (template for lesson plan, protocol for discussion, etc.) 4.Suggested teacher-led inquiry process to explore and use resource kit

21. Teachers Solve and Discuss Student Tasks Problem 1 Estimate the answer to You will not have time to solve the problem using paper and pencil. Discussion Questions: How did you solve the problem, and how might students solve the problem? Student responses to this task are provided at the end of this section (p. 14). Discuss why students chose each of the responses shown.

22. Teachers try a problem: Find the length of the mystery strip

23. Sample 11 States and 27 districts 13 Groups per condition (4-9 teachers per group, locally formed) 213 Teachers  41% New to Lesson Study  78% Elementary Teachers 1,059 Students (Grades 2-5)

24. Teachers’ Fractions Knowledge (Z-score)

25. Teachers’ Reflections “The question of linear versus a “pie” understanding was really compelling for me. It’s a distinction in the concept of fractions that I hadn’t considered and I wonder what my own understanding of fractions would be like if I had been first introduced that way.”

26. Change in Students’ Fractions Knowledge (Absolute Score, N=1059)

27. Teachers’ Reflections I've always understood how to work with fractions but didn't understand all of the "why's" behind the procedures…My students made many awesome discoveries because I learned how important a true conceptual understanding of unit fractions is to students’ overall understanding of other fraction concepts. [39-680]

28. Survey Item Examples Expectations for Student Achievement “By trying a different teaching method, I can significantly affect a student’s achievement” (7 items; α=.64 ) Using and Promoting Student Thinking “I have some good strategies for making students’ mathematical thinking visible” (4 items; α=.68)

29. When Solar Energy Was Added to the Japanese National Curriculum…. Hundreds of elementary schools applied for small grants as “designated research schools” on how to teach solar energy After about a year of experimentation, often in collaboration with university- based colleagues, schools brought to life their thinking in large public research lessons

30. Solar energy, cont’d Thousands of educators saw these research lessons and questioned teachers about why they chose these approaches, what had worked and hadn’t Knowledge quickly spread about the science content itself, good teaching materials (what toys work and don’t to illuminate the principles), and student thinking.

31. Solar energy, cont’d A teacher observing a public research lesson asked about three student strategies she saw: moving a solar cell closer to a light source adding a second light source using a magnifying class to “concentrate” light “I want to know whether the three conditions the children described ­– ‘to put the solar cell closer to the light source,’ ‘to make the light stronger’ and to ‘gather the light – would all be considered the same thing by scientists. They don’t seem the same to me. But I want to ask the teachers who know science whether scientists would regard them as the same thing.”

32. Using Lesson Study, Japanese Teachers: Develop and share their practice-based knowledge about how to teach new standards Shifts policy from “pushed in” by administrators to “pulled in” by teachers, who actively experiment with ideas, bring them to life in the classroom Allow policymakers to do “formative research” on policy

33. Using Lesson Study, Japanese Teachers: Changes the national conversation as well, so that policy is talked about in the context of actual, shared classroom practice seen by policymakers Allow policymakers to do “formative research” on policy

34. Lesson Study has grown and prospered since 2000 Silicon Valley Mathematics Initiative’s Lesson Study Project www.svmimac.org

35. SVMI provides a mini-grant to a LS team at a school or district. Many teams attend a 5- day summer institute on Lesson Study. All teams participate in Fall orientation. Teams research, design and plan a lesson (often building off existing lessons). Teams try out initial lesson designs in classrooms. Team members observe student thinking. Teams use the student data to revise and polish the lesson. When research lesson is refined the team conducts exchange lessons with another team in the project (often from a different district). All teams engage in the Annual Public Lesson Open House Teams report to schools and instruction improves. SVMI’s Lesson Study Project Model

36. Which is a 4 X 5 rectangle? What was each student thinking? (During lesson by Akihiko Takahashi, 2002)

37. Lesson Inspired Teachers to Develop and Spread “Re-engagement” Lesson Inspired Teachers to Develop and Spread “Re-engagement” “Re-engagement” strategy to revisit and reconsider student thinking “Re-engagement” strategy to revisit and reconsider student thinking. Spread across: At least 7 districts Elementary and secondary classrooms Subject areas (math, language arts, etc.) School-foundation boundary

51. Successful Lesson Study Allows teachers to develop knowledge and beliefs to support improvement– allows teachers to develop their minds and hearts Changes relationships among teachers. “Changes the talk around the water cooler” at a school so that teachers become more willing to share difficulties

52. The opportunity to focus on two to four students’ learning was incredible…You feel like you are in a true research mode. Elementary Teacher, California 52 Teachers’ Reflections

53. Until lesson study we never discussed the value of the content being taught. We discussed the different ways students learn (multiple intelligences), how the brain works, how to differentiate an inclusion class. Never had those discussions involved a discussion of how to develop problem- solving techniques, how to develop a particular concept …what to expect for outcomes, and how to adjust the lesson to meet student needs. Secondary Teacher, Massachusetts

54. Teachers’ Reflections The lesson study has taught me: We must never assume that all students understand. It was observed several times that even our "good" students did not have full understanding….Lesson study is staff development in its purest form. Rich discussion occurs. Team members are allowed to be creative, curious, self- motivated participants. The team building was incredible.” Elementary Teacher, NY #562
