Designing and Delivering Professional Development Summary
Sunday - Friday, July 1 - 6, 2007
Sunday, July 1, 2007
The program began with introductions of the participants and of the leaders, Gail Burrill, Jim King, and
facilitator, Johnny W. Lott. The fifteen participants were from California, Colorado, Maine, Minnesota, New
Jersey, New Mexico, Texas, and Washington. They included experienced PDO leaders, PD3 leaders, and others
involved in professional development in a variety of ways. Jennie Bay-Williams of the University of Louisville,
President of the Association of Mathematics Teacher Educators was present for the first two days.
To set the stage for a discussion of reasoning and proof, participants were sent a reading by Gershon Harel
and Larry Sowder on proof that will appear in an upcoming National Council of Teachers of Mathematics
research volume. Participants were given an opportunity to respond to the article with their initial thoughts
and were asked to keep considering it during the week. An underlying question for potential professional
development is how to deal with reasoning and proof at different levels. A problem involving mathematical
induction and the use of recursion or closed formulas was discussed. The goal for most days was not to solve
the problem but to consider the process.
Nicole Davis, from the Seattle team, gave a presentation on complex instruction and group learning (see file).
The participants solved a problem involving compactness and how it might be defined, then reflected on the
interaction of the groups as they were working on the task, in particular considering the discussion and
interaction that was useful among members and the strategies and behaviors of the facilitator to help the
groups make progress.
One feature of the sessions for the week of DDPD was the use of comment cards with three questions: (1)
what did you like about today; (2) what bothered you about today; (3) what else would you have liked to see

The DDPD group participated in the PCMI SSTP program and spent a small portion of their time together at the
end of the day reflecting on what they had observed/ This was followed by problems presented by Johnny Lott
and Gail Burrill (see the Japanese pattern problem), which gave the participants a time to work together, to
consider how different patterns might emerge from simple problems, how the patterns might be expanded for
teachers from lower grades to upper grades in professional development and how reasoning and proof might
be involved at different levels.
Tuesday, July 3, 2007
The day began with a continuation of the patterns and reasoning from the previous day where participants
described their solutions and discussed whether reasoning frim the picture could be a proof. One example
(that the growth was the sum of the squares, which could be observed by cutting the pattern apart and
rebuilding it as a square) provided a good explanation of the relationship between the stage number and the
growth of the pattern but did not actually reach the level of a proof (one suggestion was to reposition the
blocks so that what was added to the new stage was clearly visible and could be generalized). Darryl Yong
from Harvey Mudd College then presented an outreach effort by his PDO. An Imagine Math day for area
students and their teachers structured by the PDO members has been held for the last two years. The day is
organized around a mathematical theme; the one shared was the Graph Complexity Project from 2006 (see
the facilitator's guide for the activity).
Wednesday, July 4, 2007
There were no sessions on the Fourth of July. Many participants enjoyed the Park City parade.

11:00 AM - Extra Session
The discussion focused on characteristics of professional development such as the following:
Necessities for Professional Development
Challenges or issues for your professional development
- Identification of audience
- Meet with audience, what are needs
- Set realistic goals
- Work on timeline to reach goals
- Choose style of professional development depending on goals
- For community - consider the example of Darryl Yong, Harvey Mudd College
- Planned In-services: content knowledge, pedagogy; blend?
- Conferences and workshops
- Attending; building conferences and workshops to present
- Writing materials
- Placing professional development in work day
- Range of teachers from elementary to high school with all different mixes
- Teacher buy-in; administrative buy-in
- Time for professional development
- Prioritizing for professional development
- Outreach by teachers to parents, community and to other teachers
- High turnover rate of teachers in some districts
- District goals and individual goals may not mesh with professional development goals
- Work with administration on resources and time for professional development
- Use of money to get most out of it
- Maintaining teacher interest in professional development during year
- New standards for school districts and state and how to keep current
- Balance the needs of audience during professional development
- Scaling up/Sustainability
- Human capital - how do you keep using the same people over and over?
- Narrow focus on of immediate problems
- External issues
- District wants versus teacher wants
Johnny Lott passed out a set of problems called Chunks of Gold: The Best Mathematics Problems Ever
Reproduced for DDPD at PCMI.
1:00 Extra Session
At 1:00 in the tent, individuals wanting to meet with Johnny Lott were given time to discuss issues that
were facing them in the coming year. Individuals from New Mexico, Colorado, Iowa and Minnesota met.
4:30 Normal Session
Brian Hopkins of St. Peter's College, New Jersey, presented a mathematical content topic used in his New
Jersey PDO that presented a vision of bijective proof used in some discrete problems. He has used the
content to encourage the PDO teachers to think beyond the bounds of traditional material in classrooms.
Friday, July 6, 2007
Henri Picciotto presented a reflection on proof from his experience in the classroom, where one of his
suggestions was that investigating the situation prior to working through the proof made the proof more
meaningful for his students.
The group reflected back on the original discussion about proof and its role in professional development. The
notion that proof should be developed across student's mathematical experiences was raised as critical, but it
was also noted that this should be appropriate for the level of the student. One of the key elements that both
teachers and students should be aware of is that while it is important to "tell the truth" it is not always
necessary to "tell the whole truth" and that often a proof has to be trimmed down from the full mathematical
argument to be suitable and understandable by students at an appropriate grade level. Participants reflected
on their overall experience at PCMI and its value for their own work.
