Hi Karen
 
We routinely use TBL in classrooms of 160 students (fixed seat tiered lecture theatre)
 
And use a variety of reporting strategies in the larger classes.....mostly the typical hand paddles...but have used a Google doc a few times (all teams can edit same document at same time.....Instructor preformats document then share login info with whole class.....instructor can display the results instantaneously after student report)
 
The only struggle we have is with energy in the reporting discussion since only 1 of 160 can speak at one time
 
---------------------------------------
 
One of my courses divides the room into 4 divisions with 7-8 teams in each division.....this help the instructor move the discussion around the room
 
In this same course they do a lot of activities where the lowest price option that survives class scrutiny wins some bonus marks.....they use the division here as well....I get bonus points if my division wins....so even though my teams design may have been eliminated......I may argue for another team in my division.....to get my bonus marks
 
--------------------------------------
 
I think at University of Texas Austin they have done TBL in classes of 380
 
I have heard rumours of classes of 500....but no details
 
-------------------------------------
 
With 280 students you could consider using your course management system to move the individual test out of class time?....maybe clickers?
 
Cheers
 
Jim

Subject: Large Intro Biology TBL courses

Hello Everyone,

I will be attending my first TBL conference in Austin this March and am hoping to connect with others teaching undergrad intro science courses, specifically Biology.  I am experienced with interactive engagement teaching approaches in smaller class sizes (e.g. 30 students) but I am looking for expertise and resources applicable to using the TBL approach in large sections of an intro non majors biology course with 240 students for Fall 2009.  Also, I am very interested in learning more about technology enabled TBL in large courses.  Thanks, in advance for your time.  I am looking forward to meeting new TBL colleagues and sharing ideas!

Regards,
Karen
