How Interactive are Lectures? - A case
study from a flipped introductory
Physics class

2. ● Rationale
●
● ‘Active’ better than ‘passive’
● e.g. Hake, Am. J. Phys. 66, 64 (1998), Freeman, et al. Proc. Natl. Acad.
Sci. U.S.A. 111, 8410 (2014).
● BUT - What is an ‘active’ lecture ?
Aim
● Characterise interactions in lectures
● Develop a framework for interactive learning
● Analyse a case study from 1st year physics
●

3. Method
● Subjects: Two 1st year ‘flipped’ physics courses.
● Pre-readings (before lecture).
● Peer-Instruction (during lecture).
● Data Collection: Lecture Capture Videos.
● 16 lectures, 8 from each course (1A and 1B).
● Coding:
● Constructivist grounded theory approach.
● Activities coded on a continuous (per second) basis.

Physics 1A Physics 1B
55% lecturer talking on average

8. ● Conclusions
●
● FILL framework useful for characterising
interactions in lectures.
● 55% of time is spent on non-interactive
(passive) activities.
● Differences between 1A and 1B indicate
importance of local context.
