  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

  Tablet to allow spontaneity and bring discussion
  to the electronic lecture
• Multiple tablets enables student activities and
  active learning
  – Anonymity can be a benefit
