Students' Use of Three-Dimensional Modelling While Designing and Making a Solution to a Technological Problem.
Welch, Malcolm
Modeling in all its forms (two-dimensional, three-dimensional, mathematical, and computer) is an essential feature of designing and making. This paper describes how 10 untutored technology education students in grade 7 used three-dimensional modeling while designing and making a solution to a technological problem. This paper is part of a larger study that explored the conflict between the design strategies students bring to the classroom and those advocated in the technology education literature. Subjects were paired into five single-sex dyads. Each dyad was given a design task to create a paper tower, with specific constraints and criteria for the finished product. Each problem-solving session was audio and video recorded. A retrospective interview was also conducted with the subjects. Subjects' comments during the problem-solving session and the retrospective interviews were transcribed, segmented, and coded into six categories. The first five coding categories describe the stages of the theoretical model of the design process: understanding the problem; generating possible solutions; modeling a possible solution; building a solution; and evaluation. The sixth category describes such activities as off-task talk and researcher instructions. Subjects used three-dimensional modeling to support a range of activities, including increasing understanding of the problem, stimulating the generation of solutions, seeing what a design would look like, testing, and continuously incorporating modifications and improvements into a solution.
