Should we project slides from a
computer?
Pros:
– High quality materials
– Ease of sharing and re-use
– Ability to switch to other computer applications
Cons:
– Limits Flexibility in Learning Environment
e.g. respond to student questions, work out examples in
real time, integrate student input into presentation

Experience with Student Activities
• Solve problems in parallel
– Save time by having students view results of variations
of problem
• for, while, do while
• Allow for truly independent brainstorming or
design work
– Students cannot be influenced by work of those around
them
• Allow for modification of complex designs
– Supports backgrounds (datapaths, number lines)
• Provides anonymity – select problem, not student
– No name is attached
– Students can choose not to submit
