Processing of multiple representations in multimedia learning environments is considered to help learners obtain a more complete overview of the domain and gain deeper knowledge. This is based on the idea that relating and translating different representations leads to reflection beyond the boundaries and details of the separate representations.…

The interoperability of educational systems, encouraged by the development of specifications, standards and tools related to the Semantic Web is limited to the exchange of information in domain and student models. High system interoperability requires that a common framework be defined that represents the functional essence of educational systems.…

We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

Understanding the impact of different technological media on the achievement of instructional goals enables the delivery of a subject matter more effectively. Among the various instructional technologies that advance learning, educators and practitioners recurrently identify interactive multimedia as a very powerful tool for instruction and…

This paper covers an experiment designed to investigate the relationship between the didactical setting and learning effects with animations. We investigated whether the cognitive load imposed by animations could be reduced when the students could control the flow of the animation. We did not find an effect due to the fact that the students did…

This paper presents a hybrid course framework at the Teachers College at Columbia University (New York) that seamlessly integrates a traditional course plan designed for on-campus students with an online course plan designed for distance learning students. Based on innovative teaching and learning principles, the course encourages active…

This paper reports on a study that observed students creating structured hypertext documents, and how they try to convey structural information, in order to formulate tentative guidelines/principles for the design of concept mapping tools or hypertext systems with an emphasis on the representation of structural knowledge, and to formulated…
