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)
Group Formation is a complex and important step to design effective collaborative learning activities. Through the adequate selection of individuals to a group, it is possible to create environments that foster the occurrence of meaningful interactions, and thereby, increasing robust learning and intellectual growth. Many researchers indicate that the(More)
There is an increase use of ontology-driven approaches to support requirements engineering (RE) activities, such as elicitation, analysis, specification, validation and management of requirements. However, the RE community still lacks a comprehensive understanding of how ontologies are used in RE process. Thus, the main objective of this work is to(More)
Among other applications of educational data mining, evaluation of student models is essential for an adaptive educational system. This paper describes the evaluation of a Bayesian model of student misconceptions in the domain of decimals. The Bayesian model supports a remote adaptation service for an Intelligent Tutoring System within a project focused on(More)
Group formation plays a critical role in collaborative learning (CL). It affects the acceptance of group activities by learners and the success of the collaborative learning process. Nevertheless, proposing an effective and pedagogically sound group formation is a very complex issue due to the multiple factors that influence group arrangement. The main goal(More)
The development and use of Virtual Learning Environments (VLE) has increased considerably over the past decades. Following that trend, many research findings have shown the benefits of using VLE during the learning process. Nevertheless, there are important problems that hinder their use requiring further investigation. Among them, one of the main problems(More)
Worked examples have been found to be effective tools in reducing cognitive load and supporting learning. Erroneous examples are worked examples that include incorrect steps and are intended to help students learn how to identify important principles and errors to avoid. The current study examines whether using erroneous examples in an online intelligent(More)
Interactive Geometry (IG) is a computational approach to teach geometry using interactive geometric objects. It is based on the learning-by-doing method where the representation and manipulation of geometric spaces can support students to construct their knowledge through experience. Several research findings indicate various benefits of using IG in(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)
