In order for an Intelligent Tutoring System (ITS) to correct students' exercises, it must know how to solve the same type of problems that students do and the related knowledge components. It can, thereby, compare the desirable solution with the student's answer. This task can be accomplished by an expert system. However, it has some drawbacks, such as an(More)
The expansion of the World Wide Web and the use of computers in education have increased the demand for Web courses and, consequently, the need for systems that simplify their production and reuse. Such systems must provide means to show the contents in an individualized and dynamic way, which requires they present flexibility and interactivity as main(More)
One of the main difficulties during the design of collaborative learning activities is adequate group formation. In any type of collaboration, group formation plays a critical role in the learners' acceptance of group activities, as well as the success of the collaborative learning process. Nevertheless, to propose both an effective and pedagogically sound(More)
Two of the most important research subjects during the development of intelligent authoring systems (IAS) for education are the modeling of knowledge and the extraction of knowledge flows from theory to practice. It bridges the gap between theoretical understanding about learning and the practical foundations of design the knowledge of intelligent systems(More)
To evaluate the teaching-learning process in collaborative learning sessions and its educational benefits for learners, we should analyze the interaction process during each session and select appropriate learning goals and tasks for each learner. However, the interaction process is very difficult to analyze, even for experts, and furthermore choosing(More)
One of the main problems facing the development of ontology-aware authoring systems (OAS) is to link well-designed domain-independent knowledge (ontologies) with domain content. Such a problem comes from the fact that all OAS developed to date require end-users (non-experts) to create their own domain ontologies to run the system in real scenarios. In(More)
