Hi We use both….but prefer the longer times If you have the control….I would go for the longer classes jim -- Jim Sibley Director Centre for Instructional Support Faculty of Applied Science University of British Columbia 2205-6250 Applied Science Lane Vancouver, BC Canada V6T 1Z4 Phone 604.822.9241 Fax 604.822.7006 Email: [log in to unmask]<applewebdata:[log in to unmask]> Web: http://cis.apsc.ubc.ca<http://cis.apsc.ubc.ca/> © Copyright 2012, Jim Sibley, All rights reserved The information contained in this e-mail message and any attachments (collectively "message") is intended only for the personal and confidential use of the recipient (or recipients) named above.

Its a biology course for non-majors, with a weekly lab. The course will be structured into 4-5 modules over the course of the semester. I am considering how to set up the class sessions - formally I will have designated "lecture" and "lab" times on the schedule, although I am considering at least partly abandoning that distinction in practice and using some of the "lecture" for lab activities and some of the lab times for extended applications. But in designing this course and thinking about the schedule, I am looking for advice about meeting 3x per week (55 minutes MWF) for "lecture" vs meeting 2x per week (80 minutes TuTh). I'm wondering if instructors who have tried either or both of these options have any comments about the pros and cons. Elaine Elaine Larsen, PhD Biology Department Skidmore College 518-580-5072
