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).

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?

agenda for this session
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
slide5

The PD Materials

  • Videocase centered
  • Modular
  • Sequenced PD curriculum
  • Learning and Teaching Linear Functions
growing dots 1 lesson task

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?

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

Video Segment Questions

What important mathematical issues arise for the teacher and students within this segment of classroom interaction?

mathematical knowledge for teaching
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

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

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?
