Almost every K-8 technology activity includes feedback. Technology teachers generally view the input-process-output paradigm as being incomplete. A step toward completion would be the inclusion of a "feedback" component incorporating reengineering. This article provides an example of how one activity evolved through several stages to include reengineering: (Stage 1) the "one-shot" activity; (Stage 2) inquiry-based research and testing; and (Stage 3) reengineering. The author contends that reengineering is an approach to technology education that can complement other methods, such as creative problem-solving, enterprise, and exploratory research.
