This project focuses on creating a virtual environment for interactive exploration of mathematics, promoting understanding and personalization in math education. The goal is to improve math education by using ICT to visualize concepts, interact with formulas, and personalize the presentation.

Centre for user-oriented IT-Design (CID) CID is a competence centre at KTH that provides an interdisciplinary environment for applied research on design of human-computer interaction. CID is engaged in 4 different areas of research: • Connected Communities (Digital Worlds). • Interactive Learning Environments. • New forms of Interaction. • User orientation.
Goals and characteristics of CID • integrate usability with technical and aesthetic aspects. • create an attractive environment at KTH for strong cooperation between academy, industry and users. • produce “pre-competitive” results in the form of prototypes, demonstrators and user studies. • strong international collaboration.
A Knowledge Manifold • is a conceptual framework for designing interactive learning environments that support Inquiry Based Learning. • can be regarded as a Knowledge Patchwork, with a number of linked Knowledge Patches, each with its own Knowledge Gardener. • gives the users the opportunity to ask questions and search for certifiedhumanKnowledge Sources.
A Knowledge Manifold (cont.) • has access to distributed archives of resource components. • allows teachers to compose components and construct customized learning environments. • makes use of conceptual modeling to support separation of content from context. • contains a conceptual exploration tool(Conzilla) that supports these principles and activites.
Structure of today’s math education system Closed layered architecture based on: • curricular-oriented ”knowledge pushing”. • life long teaching with: • lack of subject understanding in the early layers. • minimization of teaching duties in the final layers.
Problems with today’s math education It does not: • stimulate interest. • promote understanding. • support personalization. • support transition between the different layers. • integrate abstractions with applications. • integrate mathematics with human culture.
Possibilities for improving math education Promoting life-long learning based on interest by: • using ICT to increase the ”cognitive contact” by: • visualizing the concepts. • interacting with the formulas. • personalizing the presentation. • routing the questions to live resources. • improving the narrative by: • showing before proving. • proving only when the need is evident. • focusing on the evolutional history.
Ongoing Mathematical KM work at CID • Virtual Mathematics Exploratorium with Conzilla • Interactive geometrical constructions with PDB • Interacting with mathematical formulas • using LiveGraphics3D / Graphing Calculator • Dynamically uploadable math component archives • CyberMath: a shared 3D ILE for exploring math
CyberMath: A Shared Virtual Environment for the Interactive Exploration of Mathematics Goals: The CyberMath system should allow: • teaching of both elementary, intermediate and advanced mathematics and geometry. • the teacher to teach in a direct manner. • teachers to present material that is hard to visualize using standard teaching tools. • students to work together in groups. • global sharing of resources. Means: • Making use of advanced VR technology (e.g. DIVE).
Definition of Presence at a Distance Presence at a distanceis defined as the subjective experience of being in one placeor environment, even when one is physically situated in another. Presence journal 2000
Factors creating a sense of presence and reality • sensory environment • vividness • depth & breadth • interactivity and control • company of others • individual preconditions • imagination • emotional state • associative context • suspension of disbelief • content characteristics • plot and story • narration and dramaturgy • presentation and execution
