چکیده
How to introduce computer-assisted design (CAD) as a representational tool of the trade in the classroom? This paper deals with the tension between the authenticity of designbased learning situations that is often strived at and the inherent complexity of the design process and CAD as a representational tool of the trade. We describe a three-dimensional framework for comparing innovative project-like scenarios in technology curricula to more traditional instructional sequences for science learning. We subsequently developed a dissociated geometry-oriented and an integrated technology-oriented CAD training and studied their influence on the way pupils engaged in a design task. Although the results show evidence of the complementary roles of different types of representations, no effect of type of CAD training is found. In the discussion, we propose potential explanations for these findings, by relating back to our framework, and make a suggestion for future research.

On the stability of equilibrium for a reformulated foreign trade model of three countries
In this paper, we study the stability of equilibrium for a foreign trade model consisting of three countries. As the gravity equation has been proven an excellent tool of analysis and adequately stable over time and space all over the world, we further enhance the problem to three masses. We use the basic Structure of Heckscher–Ohlin–Samuelson model. The national income equals consumption outla...
