Comunicação publicada nas atas da conferência IASTED 2007 – International Association os Science and technology for Development, Thailand, 2-4 de abril 2007.http://hdl.handle.net/10400.2/14638In this paper we propose a Framework QEF (Quantitative Evaluation Framework) to evaluate educational software systems built with X-TEC (Techno-Didactical Extension for Instruction/Learning Based on Computer) model, in order to validate and strengthen the potential quality of eLearning systems. The Quantitative Evaluation Framework evaluates the Educational software quality on a three dimensional space. Each dimension aggregates a set of factors. A given factor is a component that represents the system performance from a particular point of view. The quality of a given system is defined in a tridimensional Cartesian quality space and measured, in percentage, relatively to a hypothetically ideal system, represented in our quality space.engComputer based learningEducational software developmentInstructional designLearning environmentEducational software evaluationSoftware engineeringconference object
