This paper presents the overall evaluation of the Quantitative
Evaluation Framework (QEF) approach which has been applied
in an operational teaching environment for the last six years.
During this period we have evaluated the difference between
educational software systems that were developed using the
Techno-Didactical Extension for Instruction/Learning Based on
Computer (X-TEC) model and educational software systems
using other models. The X-TEC model is used in the
development of educational software in order to strengthen the
potential quality of e-Learning systems. We selected the QEF
approach for this evaluation to highlight the strengths and
limitations of the X-TEC model. We adapted the approach in a
way where the essential criteria are assessed in a pre-evaluation
phase which will cover the general usage requirements.
In this research project we conduct experiments with groups of
students and teachers in Multimedia Information Systems
classes of Oporto Polytechnic, to examine the influence of
training in an instructional system design approach on their
attitude to re-use this approach and on their performances in
design, using this approach.
