HI, Jim
I'm willing to help but not pushing to be on the committee.  Let me know if I can help. Maybe an intermediate step would be to ask all of us to send 5 topics for potential inclusion and let your committee consider those suggestions as part of their final deliberations.  There would be no obligation, of course, for the committee to use ANY of the suggestions, it would just take some of the workload away from the committee.  I note that you're doing  a TCT conference on Sept. 4.  You might want to ask some, or all, of the presenters to appear at a TB to outline in 5 minutes (no more than 10 minutes) the gist of their topics.  OR - -you might decide that people who wanted to hear the  conference topics should have attended the conference and you want new or additional topics for the TB.

In the spirit of taking my own suggestions, here is my list of 5 (or 6)  topics that interest me.  As usual, they are practical, pragmatic, not theoretical:

1) Teaching Better and Saving Time using Hybrid courses
2) Examples of better teaching using Electronic Portfolios
3) Better Teaching for Large Classes
4) Best ways to assess student learning
5) Teaching students how to write well
6) A practical meeting with specific ideas given from the Grant Writing folks on campus, updating us about their facilities, help, etc.

Another idea is to form the faculty group we've discussed for so many years.  The group would have a protocol for watching teachers conduct classes and would comment on what was done well and what might be changed.  The focus of the group would be to encourage better teaching and demonstrably better student outcomes while helping the faculty member to cut back, or at least not increase, the time already spent in class prep, grading of papers/projects, etc.
