KIPPERMAN, D., 2000. Evaluation-modification loops in the the design process used by students building technological devices. IN: Kimbell, R. (ed.). Design and Technology International Millennium Conference. Wellesbourne : The D&T Association, pp. 100-106
This research is based on observations of and interviews with five seventh grade students during problem solving
activities in a technological context. When left to their own devices in an environment rich in three-dimensional
materials (Lego components), they follow Evaluation-Modification Loops. The research is based on:
1. observations during class activity over one semester (12 meetings)
2. open interviews with each student during class activities.
The study focused on two issues:
1. identifying the characteristics of the design process of technological devices
2. students’ attitude towards their original design goals during the process of designing technological devices.
An Evaluation-Modification Loops model containing decision making space was developed based on the
observations and interviews.
