DO RESEARCH LESSON Conduct research lesson Collect data Why Toolkits? • Kyouzai kenkyuu (“curriculum study”) is important part of lesson study • U.S. textbooks may not support “curriculum study” of the mathematics, student thinking • Much U.S. mathematics education research is not well-reflected in teachers’ manual or textbook Toolkit Topics • Proportional Reasoning • Area of Polygons Toolkit Contents • Mathematical Tasks & Student Work • Curriculum Materials • Research Articles & Summaries • Lesson Videos • Reflection Forms & Questions Mathematical Tasks (Ex: NAEP) Curriculum Materials Research (Examples) • Driscoll, Mark, Nikula, Kelemanik, DiMatteo & Egan (2007) - The Fostering Geometric Thinking Toolkit: A Guide for Staff Development, Heinemann (Area). • Lamon (2006) - Teaching Fractions and Ratios For Understanding, Erlbaum (PR). Lesson Videos (Example) Can You Find the Area? Akihiko Takahashi, U.S. Classroom Reflection Forms and Questions (examples) • Concept map: Sequence of understandings that students develop • Daily meeting reflection • Reflection on lesson study cycle Data Sources • Teacher assessment (pre and post) • Reflection forms • Lesson study artifacts • Video data of lesson study meetings & research lesson for 4 “intensive study” groups Sample Number of Participants Individual Teachers Groups Elementary Teacher Middle Teacher Current High Teacher Position Not Teaching Years <5 Years Teaching 5-14 Years Experience 15+ Years New to LS Years Prior Done 1 LS Cycle Lesson Study Done LS for 1-2 Yrs Experience Done LS for 3+ Yrs % With Math Degree/ Credential Assigned PR Assigned AP Toolkit Toolkit 44 37 8 8 21% 46% 59% 30% 14% 16% 7% 8% 18% 31% 50% 46% 32% 23% 36% 49% 16% 11% 16% 22% 32% 19% 48% 41% Comparison Teachers 28 6 41% 30% 11% 19% 26% 73% 11% 59% 15% 15% 11% 39% Outcomes: Mathematical Knowledge for Teaching Outcomes: Knowledge Mathematics Knowledge for Teaching (Hill & Ball; Univ. of Chicago School Mathematics Project) Standardized Teacher Assessment Items # # Question Individual Stems Items Proportional Reasoning Subtest Area of Polygons Subtest 11 7 Source (# Items from Source) 24 LM T (2 4 10 LM T (5 ), U C SM (4 ), N A E P (1 Standardized Scores on Proportional Reasoning Subtest 0 .4 0 Standard Deviation Units 0 .3 0 0 .3 0 0 .3 2 0 .2 0 P retes t P os ttes t 0 .1 0 0 .0 0 - 0 .1 0 - 0 .1 7 - 0 .2 0 P R T oolkit T eac hers (N =4 4 ) - 0 .1 7 C omparis on T eac hers (N =2 8 ) Standarized Scores on Area of Polygons Subtest 0 .1 0 .0 4 0 .0 5 Standard Deviation Units 0 - 0 .0 5 - 0 .0 2 - 0 .1 P retes t P os ttes t - 0 .1 5 - 0 .2 - 0 .2 5 - 0 .2 6 - 0 .3 - 0 .3 1 - 0 .3 5 A P T oolkit T eac hers (N =3 7 ) C omparis on T eac hers (N =2 8 ) Prop Reasoning Item At the currency exchange, Jean-Pierre can get three Euros for every four Dollars he trades in. a) Jean-Pierre wonders if this is a proportional situation. Is it? Why or why not? b) Make a table, graph, and equation to show Jean-Pierre the relationship of Euros and Dollars. c) What aspects of the table, graph, and equation might help Jean-Pierre notice whether the relationship is proportional?

Teachers’ Knowledge • No significant impact on standardized assessment items of MKT • Impact on open-ended assessment items and self-reported knowledge of topics Teachers’ Personal Dispositions • Some evidence of increased enjoyment and expectations Teacher Learning Community • Increase in self-reported collegial learning effectiveness Final Thoughts • Standardized MKT assessment items may not be a good fit for lesson study, since a group’s focus cannot be specified in advance • Need for research to follow groups over multiple cycles, to see whether changes self-reported collegial learning effectiveness and personal dispositions have future impact • Our simple linear model does not capture any loops within the model – for example, how collegial learning effectiveness affects knowledge or vice versa.
