Recently, many authors have considered the problem of simultaneous localisation and mapping (SLAM). The paper addresses a somewhat diierent problem, that of cooperative localisation and mapping (CLAM). Basically, CLAM involves two or more robots cooperating to build a map of the environment. This cooperation is not aimed at simply increasing the speed with which the map is constructed; rather, ...

The mutual relationship among Markov partitions is investigated for one-dimensional piecewise monotonic map. It is shown that if a Markov partition is regarded as a map-refinement of the other Markov partition, that is, a concept we newly introduce in this article, one can uniquely translate a set of symbolic sequences by one Markov partition to those by the other or vice versa. However, the se...

The proposed tool describes the subject to learn from an evolution of conceptual maps, called Pedagogical Concept Instructional Graph (PCIG), generated by the teacher. A PCIG does not order the concepts following arbitrary relationships among them as in the case of a general concept map, but the concepts are placed depending on the logical order in which they are presented to the student. After...

Since the late eighties, more and more researchers have been exploring the potential of collaborative concept mapping to support learning. In those studies, students construct concept maps in pairs or in small groups. This paper presents a review of research trends on collaborative concept mapping in education. We present an overview of the theoretical framework, methodology and main results of...

We propose an approach to clustering and visualization of students' cognitive structural models. We use the self-organizing map (SOM) combined with Ward's clustering to conduct cluster analysis. In the study carried out on 100 subjects, a conceptual understanding test consisting of open-ended questions was used as a data collection tool. The results of analyses indicated that students construct...

Concept maps were used as a way to organize concepts and ideas for two large scale projects. One project was a dissertation encompassing several sub-areas in cognition and visual perception, and the other was a joint project on uses of concept maps. Concept map and associated resources can provide a powerful way for researchers to organize and make sense of large domains of research, either on ...

Concept mapping is a tool to represent interrelationships among concepts. Relevant research has consistently shown the positive impacts of concept mapping on students’ meaningful learning. However, concerns have been raised that concept mapping can be time consuming and may impose a high cognitive load on students. To alleviate these concerns, research has explored facilitating concept map cons...

We are interested in evaluating interactive retrieval systems from the user’s perspective. In this position paper, we introduce a user study evaluating the cognitive change in users’ knowledge by using concept maps.

This paper describes the process followed for visualizing, using DynMap, the student’s evolution through the learning process in a Computer Security course at the University. DynMap is a system based on Concept Maps developed with the aim of providing the education community with a tool that facilitates the inspection student data. After a brief introduction, the paper describes the problem to ...
