Multimedia Technology, Technology application, and Research and Development
Developers can save hundreds of hours of revision time by formatively evaluating multimedia instruction in the early development stage along with traditional design, analysis and development steps. Adding this step to the development process also ensures a higher quality instructional product. There are several strategies reflective of those posed by the Dick & Carey methodology for field trials, small group and one-to-one for accruing formative data concurrent to each step of the instructional system design (ISD) process. The chief difference between the two approaches is the early one-to-one evaluation that is executed when the multimedia product is still in the rudimentary paper stage of the ISD process. One-to-one and small group evaluations are then performed during prototyping. A field trial can coincide with the product evaluation, which eliminates the necessity for drastic revisions upon product development.
