The study examined the interaction effects of prior knowledge and hypertexts structure (network vs. hierarchy) on comprehension. Comprehension was investigated analyzing jointly three dependent variables: comprehension outcomes, coherence of the reading sequences and feelings of disorientation. The results supported most of the assumptions showing an(More)
This article presents research that aims to construct a computer-based system that (1) supports learners in organizing themselves in the context of a mediated pedagogic collective challenge and (2) supports human tutors in monitoring the learners' process, and supporting it. We present the result of an exploratory experiment that helps in understanding the(More)
Learners engaged in CSCL macro-scripts are involved in self-organization activities. We present an exploratory study that suggests that Bardram's theoretical model of collective work dynamics is a pertinent basis for both (1) designing interfaces providing a passive support that engages learners in an explicit organization activity, and (2) making learners'(More)
In this paper we present a business context information manager based on a novel and generic interpretation of the context. This manager takes into account various contextual dimensions and acts as an intermediary between information system and contextual information. First, we discuss how the manager creates a snapshot of the context that is provided to(More)
Taking into account the context is important to improve the way systems provide relevant information to users. For this purpose, we introduce a business context information manager based on a novel and generic definition of the context. This manager takes into account various contextual dimensions and acts as an intermediary between Information Access(More)
Aiming to understand and enhance metacognition in Computer Supported Collaborative Learning (CSCL), we considered time management as one of students' major challenges in CSCL. In collaborative activities, students need to know and regulate their individual and collective time being aware about their own and their teammates expected availabilities. Aiming to(More)
This paper examines the issue of help devices for students in hypermedia environments according to the learning context and, more precisely, according to the cognitive processes involved in that situation. The argument is based on a criticism of the level of generality of traditional help systems which are mostly concerned with user–system interaction.(More)
This study is about how to interpret users' interactions with multimedia systems, in particular their interaction with hypertext. It is generally admitted that our knowledge of how to interpret users' search paths in information systems is very limited. Furthermore, there are also controversies about the validity of the import of rational criteria, such as(More)
