  1. Analyzing Shifts in Teacher Discourse and Mathematical Knowledgefor TeachingNanette SeagoWestEd

  2. Focus of the Session Examine what it might mean to learn mathematical knowledge for teaching (MKT) through the analysis of two sets of PD video of teachers’ pre-post discourse (same facilitator, same PD curriculum, different teacher groups).

  3. Turning to the Evidence Project* Nanette Seago (P.I., nseago@wested.org)Lynn Goldsmith (P.I., Lgoldsmith@edc.org)Research Questions:What do teachers learn by participating in professional development that uses classroom records and artifacts? What aspects of their learning do teachers apply to their classroom practice? *This work was supported by the National Science Foundation under Grant No. 0231892. Any opinions, findings, conclusions, or recommendations expressed here are those of the authors and do not necessarily reflect the views of the National Science Foundation.

  4. Agenda for this session • Examine & engage with the PD materials • Define Mathematical Knowledge for Teaching • Examine & analyze two sets of pre-post teachers’ discourse (two different PD settings) • Discuss implications for leaders of PD

  5. The PD Materials • Videocase centered • Modular • Sequenced PD curriculum • Learning and Teaching Linear Functions

  6. At 1 minute At 2 minutes At the beginning Growing Dots 1 Lesson Task Describe the pattern. Assuming the sequence continues in the same way, how many dots are there at 100 minutes? For any number of minutes?

  7. 1 1 Sample Solution Methods “Arms” Method “Squares” Method At 2 minutes At 2 minutes dots = t(4) +1 dots = 4t + 1 # of min = # of dots in each of the 4 “arms” # of min = # of squares; 4 dots(vertices) in each “square” where t = number of minutes

  8. We drop in Situating the Video Segment Within the Lesson

  9. Classroom Teaching & Learning Kirk context Danielle & James Whole class Linear Functions Video Segment Questions What important mathematical issues arise for the teacher and students within this segment of classroom interaction?

  10. Shifting our Attention:From Classroom to Professional Development

  11. Mathematical Knowledge for Teaching Mathematical knowledge required for teaching that is different from other mathematics-intensive professions such as research mathematics, engineering, or financial modeling. MKT emerges within core activities of teaching such as: • Figuring out what students understand • Analyzing methods and solutions different from one’s own, determine their adequacy and compare them • Unpacking familiar mathematical ideas, procedures and principles in ways to make them more accessible to students • Choosing representations to effectively convey mathematical ideas • Figuring out student errors • Designing and modifying mathematical tasks Ball & Bass, 2000

  12. PD Group 1 Context: • 24 middle school mathematics teachers • Large urban school district • Session 1 of Learning and Teaching Linear Functions Foundation Module • Large group discussion of 1st video clip • Teachers have worked on and discussed the mathematics in the dots problem

  13. Predict • What might teachers tend to in the video? • What might they not tend to?

  14. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  15. Session 1 Video Clip

  16. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  17. PD Group 1; Session 8 Context: • Five months later: Session 8 of Learning and Teaching Linear Functions Foundation Module • Teachers have revisited and discussed the mathematics in the dots problem • Large group discussion of 1st video clip

  18. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are the teachers working on?

  19. Session 8 Video Clip

  20. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  21. PD Group 2 Context: • 6 middle school, 3 high school mathematics teachers • Medium-sized urban school district • Session 1 of Learning and Teaching Linear Functions Foundation Module (October) • Teachers have worked on and discussed the mathematics in the dots problem • We drop in on the large group discussion of 1st video clip

  22. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  23. Session 1 Video Clip

  24. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  25. PD Group 2; Session 8 Context: • Five months later: Session 8 of Learning and Teaching Linear Functions Foundation Module • Teachers have revisited and discussed the mathematics in the dots problem • Large group discussion of 1st video clip

  26. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  27. Session 8 Video Clip

  28. Video Focus • Use the MKT worksheet to focus on: • What are the teachers talking about as they analyze the video segment? • What core activities of teaching are teachers working on?

  29. Implications As leaders of professional development, what has this session raised for you in terms of: • Teacher learning of MKT? • Facilitating the learning of MKT?
