A study of grade 7 boys (n=6) and girls (n=4) investigated how students model ideas while designing and making. Analysis of video recordings identified five differences between modeling as described in the literature and as used by the subjects. The results suggest a need for students to model ideas in three-dimensional form early in the design…

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…
