Augmented Reality (AR) and Virtual Reality (VR) platforms now support shared, immersive experiences that enable people to directly physically and perceptually engage with mathematical objects, including shared objects. These new forms of AR/VR technology -- which we call "shared holographic AR/VR" (shAR) -- enable multiple learners to…

This research applies Socio-Cultural theory and Distributed Cognition/Activity theory to conceptualize the design of collaborative learning activities in large shared digital spaces. The paper begins by providing a summary of previous work in the creation of a technology platform for large shared digital spaces. It then details how Socio-Cultural…

The SAGRES system is an educational environment built on the Web that facilitates the organization of visits to museums, presenting museum information bases in a way adapted to the user's characteristics (capacities and preferences). The system determines the group of links appropriate to the user(s) and shows them in a resultant HTML page. In…

Education delivery systems have evolved from content delivery mechanisms to collaborative environments. The next step in this evolution is to provide greater support for asynchronous learners, those that progress through course material with little or no support from the instructional team. The integration of Web technologies with artificial…

This paper describes an ongoing experiment at the Swiss Federal Institute of Technology in Lausanne regarding the use of World Wide Web-based document annotations for educational purposes. An annotation tool called Medium was built, merging database and Web technologies, to be used as a companion for classical university courses and collaborative…

This paper presents interface guidelines from research at the University of Pittsburgh (Pennsylvania) School of Information Sciences in developing a collaborative, problem-based learning environment for the World Wide Web. The lessons learned are based on student use and evaluation of three interface prototypes over the course of 3 years and…

This paper describes a computer-supported environment designed to facilitate distance learning through collaborative problem-solving. The goal is to encourage distance learning students to work together, in order to promote both learning of collaboration and learning through collaboration. Collaboration is defined as working together on a common…

The Pennsylvania State University, through its World Campus, is exploring several design models which provide multifaceted communication environments for distance education. Currently, students enrolled in World Campus programs interact with courses delivered through WebCT, a course management tool, or through FirstClass. This paper focuses on…

This paper describes Coconuts (Concurrent Collaborative Learning Environment Supported by Awareness), a proposed module of Sharlok (Sharing, Linking and Looking-for Knowledge), an open-ended and collaborative learning environment that integrates a knowledge building tool with a collaborative interface tool. Coconuts was developed in order to…
