User Monitoring
17
Feedback Injection Brute force changes of the user interface Hiding the application behind a proxy Making use of server-side content filtering e.g. utilise Apache’s mod_filter
18
Next Steps Identify useful information for self-regulated learning Find and develop visualisations that affect learning Identify “good” feedback strategies Identify easy-to-use method of describing feedback strategies
