What does an effective e-learning video look like?
Don Leitch
Broader context
● Videos are the majority of content and the most expensive
● Blended learning, credit bearing courses
● Scalability
● Standardisation
● Instructor training
● Best practices
● Open research
Question
How do we know what makes an effective online educational video so that we can implement best practices?
How we currently make decisions about videos
● Discussion
● Intuition
● Experience of video producers and learning designers
● Film theory
● Design
● Empirical research
Data & Research
Surveys
(Pierce, 2015)
Taxonomies
(Reutemann, 2016) (Hansch et al, 2015)
Video interaction data
(Guo, Kim and Rubin, 2014)
AB testing
(Chen et al, 2016)
Controlled experiments
(Kizilcec, Papadopoulos, and Sritanyaratana, 2014)
Recurring Theme
Engagement VS Learning
Recurring Theme
Most research on educational online videos involve findings in engagement
VS
Interesting findings
Video Length
● Drop out rates and watch time used as a proxy for engagement
● Unclear if cause is length or conciseness
● Varies according to video type
(Guo, Kim and Rubin, 2014)
Setting
● Traditional lecture settings are less engaging
● Intimacy trumps production values
● Lecturer comfort and decreased cognitive load increases learner engagement
(Guo, Kim and Rubin, 2014) (Chen et al, 2016)
Rate of speech
● Correlated with engagement
● Faster is generally better
● Could be about enthusiasm
Framing
● LectureSight controlled study
● Importance of face and gestures
● Improved recognition and recall
● Very specific. Broader research needed.
(Wulff et al, 2013)
Edits (visual transitions)● Viewers navigate videos to before and after edit points
● Supports chapters and interactivity
● Argument for picture in picture (Kim et al, 2014)
Picture in picture
● Controlled study
● Avoids transitions
● Learner preference
● No significant learning difference
● Implications for multimodality and cognitive load
(Kizilcec, Papadopoulos, and Sritanyaratana, 2014)
Colour and highlights
● MOOC AB test
● Counter-intuitive results
● Dubious
● Worth further study
(Simonite, 2013)
Other questions
• Style and visual consistency
• Eye line
• Jump cuts vs multiple angles
• Correlation of video format with learning
• When is video appropriate?
Way forward
● Educators thinking like video producers and visa versa
● Data driven video production
● More detailed AB testing
● Understanding the role and importance of aesthetics
