Usability And Design Evaluation of New Interfaces of Computerized Educational Means (CEM): Delivery Work Mechanism (DWM)

Abstract

This research consisted on evaluating new interfaces usability to answer its content actualization needs by using the resources of new information and communication technologies in the teaching and learning process. The objectives proposed were: to diagnose the CEM- DWM interface evaluation need; to study the feasibility to evaluate CEM-DWM interfaces; to evaluate the
interface through the usability and accessibility engineering method; to design new CEM-DWM interfaces based on the results obtained from the evaluation, and to make a CEM-DWM operative prototype. For such purposes, the Applicability and Usability Engineering Process Model was used. From this model, the expert inspection method with Nielsen’s heuristic technique was
employed; as an inquiry method, the field observation technique and the questionnaire were utilized; and as a test method, the Think Aloud Technique was applied. Conclusions show the achievement of real users’ expectations when executing their tasks, for this product is easy to use, easy to learn and very satisfactory.
