Inside Convocation Hall at the University of Toronto

1. Engaging a Class of a Thousand StudentsJason Harlow,David Harrison and Tony KeyUniversity of Toronto - Physics Department Inside Convocation Hall at the University of Toronto

2. Talk outline • What we are doing to teach Physics to the masses • How we try to engage and motivate students in a course they hate • A Mini-Physics Lecture! • Results of student surveys • Future Plans, ideas

3. Who we are: • Jason Harlow (me): Teaching-Stream Lecturer, hired August 2004. I teach 2 or 3 physics courses per year. • David Harrison: Senior Lecturer, has taught physics at U of T since 1972 • Tony Key: retired Professor, continues to teach Communication for scientists and introductory Physics All are members of the Physics Education group at U of T

4. What we teach: • “Physics for the Life Sciences”, annual enrolment of 900-1100 students. • 26 weeks from September through April. • One-hour lectures are held twice per week in Convocation Hall, an auditorium with 2000 seats • Four professors take turns lecturing for about 6 weeks each (4 “quarters”). • Before 2003/04, this class was split into five 200-student sections

5. Outside Lecture • Bi-weekly 3-hour laboratories; Student:TA ratio=15 • Weekly 1-hour tutorials run by graduate students. Student:TA ratio=25. • Department-run Tutor Drop-In Centre • Extensive Course web-site, with course schedule, assignments, lecture notes and access to individual student marks • University-run message-board and chat-room for Life Sciences students (http://biome.utoronto.ca)

7. Sample Lecture • Reading for today’s lecture: Chapter 12: “Newton’s Theory of Gravity” • Results from Chapter 12 WebCT Pre-quiz: • 90% of students answered all 3 questions • Average mark: 85% • Correct answers on course web-page for today’s lecture

8. Sample Lecture • In-class Quiz Question: Two balls, initially at rest, are dropped simultaneously. The large ball weighs twice as much as the small ball. Which do you predict? 1. The large ball will fall at least twice as fast as the small ball. 2. The large ball will fall slightly faster than the small ball. 3. Both balls will fall at the same rate. 4. The small ball will fall slightly faster than the large ball. 5. The small ball will fall at least twice as fast as the large ball.

9. Sample Lecture • Galileo said: “When air friction is very small, all objects fall with the same acceleration”. • Two masses connected by spider silk should fall at the same rate as either mass. • Galileo was convicted of heresy, died under house arrest in 1642

10. Other things we tried… • Video cameras were pointed at demonstrations on stage, and a live image was projected on the main screen. • We paid a “runner” to wander in lectures, collect written questions in class and pass them to the professor. • The audio-component of lectures were recorded and posted on the course web-site in audio-streaming and .mp3 format.

11. Other things we tried… • Tablet-PC notes were posted on the web after class, along with PowerPoint slides. (- this resulted in a mention on the front page of the Toronto Star!!) • “Representative Assemblies” • a.k.a. “Student Management Teams” • weekly meetings with pizza • ~10 students and professor • discussion limited to issues of communication and facilities only – no discussion of course content

12. Student Survey Results • Two surveys were done in 2004/05 about our teaching techniques. Surveys were done during tutorials. • 669 students responded in October, 311 students responded in March • For all questions, students chose a number from1 to 7 where: • 1 means: totally useless • 4 means: neutral • 7 means: an invaluable aid to my learning

13. Student Survey Results • Tablet PC: The main content of the classes was delivered using the Journal program on a Tablet PC, with some PowerPoint slides and other information on the side screens. How effective was the use of the Tablet PC for your education? Spring Histogram

14. Student Survey Results • Demonstrations: Often we did demonstrations in class, sometimes in conjunction with In-Class Questions and small group discussions. In general, are demonstrations useful? Spring Histogram

15. Student Survey Results • Pre-Class Quizzes: Almost every week you did a short quiz on the textbook readings for the next 2 classes. How useful were the Pre-Class Quizzes? Spring Histogram

16. Student Survey Results • In-Class Questions: In class many times I asked the class a question and asked for a vote of what you thought was the correct answer. How useful were these questions? Spring Histogram

17. Student Survey Results • Small Group Discussion: When there was disagreement on the right answer to an In-Class Question, often you broke up into small groups to discuss it. How useful were these small group discussions? Spring Histogram

18. Future Plans • We will continue to teach the section of 1000 students together in one big room. U of T has distant plans to build a large lecture room. • Radio Frequency Personal Response Systems to replace voting cards. • More difficult in-class questions (CINQ database) • More TA-training, different format for labs and tutorials.
