SOLUTIONS
John BuschQUB Belfast School of EEECS
Context - CSC2024 Web Tech & Programming
• Web Programming• Software Development• PHP(MySQL)• ASP.NET (MSSQL)• Mixed Cohort• 110 - 200
Traditional Lectures – should contain more active learning rather than
passive learning
• Programming• Hard skill-base
Interactive Lecture– developed 2012-13 term
• Large lab• Tutor Demonstrations• Students replicated actions• Screenleap.com
What I learnt – students loved the approach but…
• Playback option• Other students• Framerate problems
• Mic & speakers• Firefighting• Tutor too fast
• Playback • Delivery via browser• Better Framerate (60fps)
• Digital audio• On/Off Campus• Free
Improve? – use a cloud-based broadcasting (screen-casting) approach
iLecture – built web UI to host live broadcasting stream
iLecture – Access on of off campus
iLecture – BROADCAST - passive
iLecture – BROADCAST - active
iLecture – communication
• Text-based, AJAX• Student respond to
queries• Student identity• Peer support
iLecture – PLAYBACK- passive
iLecture – PLAYBACK- active
iLecture – issues
• Only one session where students experience streaming problems
• Not automated (recording/hosting)• Some lag (10 – 30 seconds)• Lots of firefighting comments• Students find it difficult to keep-up
iLecture – benefits
• viewed off-campus• Students viewed same day but after
live broadcast• No plugins for PLAYBACK• Revision support• Record of student activity (module)• Learning by doing• Increased attendance compared to
traditional lecture
