Traditional Lectures – should contain more active learning rather than
passive learning
• Programming• Hard skill-base

What I learnt – students loved the approach but…
• Playback option• Other students• Framerate problems
• Mic & speakers• Firefighting• Tutor too fast
![Page 6: ILectures - D ESIGNING AND DEVELOPING INTERACTIVE LECTURES USING CLOUD - BASED BROADCASTING SOLUTIONS John Busch QUB Belfast School of EEECS](https://reader038.vdocument.in/reader038/viewer/2022110116/551ae2e6550346f70d8b4731/html5/thumbnails/6.jpg)
• Playback • Delivery via browser• Better Framerate (60fps)
• Digital audio• On/Off Campus• Free
Improve? – use a cloud-based broadcasting (screen-casting) approach
