Design of educational artifacts as support to learning process.

The aim of this paper is to identify utilization schemes developed by students and teachers in their interaction with educational workstations in the electronic measurement and instrumentation laboratory at the Department of Electrical Engineering in the Federal University of Minas Gerais (UFMG), Brazil. After that, these schemes were used to design a new workstation. For this, it was important to bear in mind that the mentioned artifacts contain two key characteristics: (1) one from the designers themselves, resulting from their experience and their technical knowledge of what they are designing and (2) the experience from users and the means through which they take advantage of and develop these artifacts, in turn rendering them appropriate to perform the proposed task - the utilization schemes developed in the process of mediation between the user and the artifact. The satisfactory fusion of these two points makes these artifacts a functional unit - the instruments. This research aims to demonstrate that identifying the utilization schemes by taking advantage of user experience and incorporating this within the design, facilitates its appropriation and, consequently, its efficiency as an instrument of learning.
