Multimedia Presentations Workshop
Group Reports
The workshop split into three groups for discussions:
Although the groups covered different areas, much of the discussion inevitably overlapped. A common theme was the difference between OHPs and electronic methods of presentation, and the need to support the move from OHPs to computers. The table below shows some of the differences between OHPs, 35mm slides and electronic presentations that were highlighted during these discussions.
