High attention intervals derived from past learners' comments¶

Description¶
High attention intervals are a learner-sourcing mechanism that aggregates comments made by past learners into continuous stretches of video, using a time-gap parameter θ (set to 4 seconds for tutorials and 6 seconds for examples) and an aggregation predicate. The intervals indicate areas in a video where users have noted something and are used to trigger interactive prompts and visualisations such as heat maps. The article states: "The high attention intervals are used for identifying situations that could trigger interactive prompts", implementing nudging as signposting through interactive visualisations and personalised prompts in AVW-Space.
Design Implications¶
Context¶
Requirements¶
- A corpus of timestamped comments from past learners, and a chosen time-gap parameter θ that gives a reasonable interval partitioning
Constraints¶
- Larger values of θ will aggregate almost all comments into one interval, limiting the granularity of the partitioning
Target Learners¶
- future learners watching videos in AVW-Space
Learning Goals¶
- noticing important segments in videos and making comments at high-attention points
