How Designers Make Decisions: A Descriptive Model of Instructional Design for Informal Learning in Museums

In response to a call for theories of instructional design that are grounded in practice, I conducted a naturalistic study of the instructional design process for three permanent museum exhibits. An analysis of the data indicated that design involves a series of decisions, each of which has 4 components: • Design goals: principles to be achieved through the decision process and that must be realized before the choice is considered complete. • Design resources: the materials–both physical and intellectual–available to present information. • Design techniques: the strategies for achieving the goals using the design resources available. • Constraints: outside influences such as budget and schedule that limit the use of resources and techniques to achieve a goal. Each phase in the design process is characterized by certain types of decisions in which one of the four components dominates. Design team members participate to different extents in design decisions based on their roles. In theory, the model should transfer from museum exhibition design to instructional design. Further study would indicate the extent as well as which design decisions are guided by research, theory, or instinct, so we might understand and ultimately improve decisions about instructional programs.     

Learning and Metamemory Failures Despite Extensive Experience

A number of studies has shown excellent recognition memory for pictures when participants are asked to remember what has been presented. This study explored unpractised memory for the English 5 note-an everyday item containing a great deal of pictorial information. Forty participants were asked to study a copy of the etching of the Rocket locomotive from the reverse side of the note. Of the participants 75% claimed never to have seen the image before, and were confident in their judgements. Further, participants were confident that experimenter claims about bank-note details were wrong. Results point to both dramatic memory failure, and to misrepresentations in memory. They provide a vivid demonstration of the failure of passive learning to encode information reliably, and the need for active learner engagement for effective recall.
