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
