Selection

1
Selection

• Selected CIT appropriate to the learning
  situation
• There is no simple prescriptive rule connecting
  the analysis of learning activities to the
  required medium Laurillard 2002 p.197
• Matching a mix of methods and technologies to the
  learning gap and the other requirements is
  creative and requires discipline teaching
  expertise.

2
Selecting

• What technologies are there? (short list
  reviewed)
• What matches the analysis? Especially the
  teaching-learning activities needed
• What is available?
• What is the best mix of media?
• What are the costs and constraints?

Balancing the media(Laurillard 2002 p. 174-177)

• How much of different media is best?
• How much electronic, how much face-to-face?
• Do the learning hours total appropriately?

6
Development costs

• Developmentdelivery time for multimedia
  courseware
• minimum 1001 developmentdelivery hours for
  experienced developers, assuming about 90 screens
  or instructional points per hour of delivery
• 200-3001 if graphics, more if sound/video

7
What determines the cost of developing
courseware?

• Marshall et al. 1994
• course difficulty number of learning objectives,
  difficulty, existence of content
• least cost if knowledge learning objectives, more
  if skill, most if attitudes
• interactivity complexity of interface,
  branching, feedback, question style
  addition/complexity of graphics, animation,
  audio, video, simulations
• development environment production tools, ID
  used, team size, subject MM experience,
• subject matter expert availability, their
  multimedia experience
