Technology Enhanced Math Rehab

  1. 1. EPFL Seminar, 2007-10-30 First Class Mathematics The Technology Enhanced Mathematics Rehabilitation Clinic Ambjörn Naeve The Knowledge Management Research Group The Royal Institute of Technology, and Uppsala University Sweden http://
  2. 2. The KMR group - what do we do? • We work with Asynchronous Public Service in the form of infrastructures, architectures, frameworks and tools that contribute towards the creation of a Public Knowledge and Learning Management Environment. • This PKLME should enable a global, (synchronous and) asynchronous public discourse that aims to enhance the learning of all participants. • Our main information architecture for this PKLME is the Knowledge Manifold (navigated in Conzilla). • All our software is Open Source and based on Semantic Web technology.
  3. 3. We work to enable a fundamental shift • From: Teacher-centric, curricular-oriented “knowledge push” • To: Learner-centric, interest-oriented “knowledge pull”
  4. 4. A traditional educational design pattern (Tenured Preacher / Learner Duty) Security Employee Confinement Prisoner Tenure Preacher Pupil School Duties Minimal Life-long learning efforts teaching: * * Teacher Learner Doing time Agent 007 in return for with a right Course a degree to kill interest
  5. 5. An emerging educational design pattern (Requested Preacher / Learner Rights) Knowledge Seeker Interest Resource Pedagogical Student Consultant School Rights Requested Life-long * * Teacher Learner teaching: learning: Course Developing You teach as long your interests as somebody is learning
  6. 6. Question-Based Learning The three fundamental questions What am I interested in? What is there to know about it? What do I want to know about it?
  7. 7. Structure of todayʼs math education system Closed, layered architecture based on: • curricular-oriented ”knowledge push”. • life long teaching with: • lack of subject understanding within the earlier layers. • minimization of teaching duties within the later layers.
  8. 8. Problems with todayʼs 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.

Expectation Child isA Shit, I’m never going to understand this stuff! Conceptual Difficulty isA Slightest sign of mental resistance Confirmation isA Yeah, just as I figured, I simply can’t understand this stuff. time
  16. 16. 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.
  17. 17. Mathematics as a de-semantization process that transforms ”meaning” into ”form” Appli- cation Meaning Form Mathe- matics Force Vector Velocity
  18. 18. Create / Apply Mathematics Apply Math Form Meaning Create Math Definition Existential Operational What is it? How does it act?
  19. 19. Create Mathematics Create Math “Forget” meaning Model Extract Turn into semantics structure definition Domain Math model skeleton

  21. 21. Project Mathemagic • Ideology: Within the mathemagic project we want to emphasize the speculative and creative aspects of mathematics. • Aim: To stimulate interest in mathematics among young and old by emphasizing “week-end mathematics”. • Basic idea: Problematize and dramatize the major mathematical concepts by anchoring them in the history of ideas. • Metdod: Improving the narrative - showing without necessarily proving. • Form: The news of yesterday: Proust: “In Search of Lost Mathematics.” Knowledge components (featuring Pythagoras, Archimedes, Newton, …) are “tied together” by a ”news anchor in space-timequot; who follows different trails along the evolution of mathematical ideas.
  22. 22. Nine Mathemagic Stories 1. The story of the people who thought the world was understandable. From Thales and Pythagoras to Demokritos and Aristarkos. 2. The story of the people that wanted to escape the realm of the senses. From Plato via Augustinus and Aquino to the “scolastic age”. 3. The mathematics of the eye: The development of true perspective. From Pappos via de la Franchesca and da Vinci to Desargues, Pascal, Poncelét, Plücker, Grassmann and Klein. 4. Einstein for Flatlanders: Two-dimensional relativity theory. The story about the flatlanders that lived on a sphere and the flatlanders that lived on a torus (“dough-nut”).
  23. 23. Nine Mathemagic Stories 5. The story of the people that disregarded almost everything. The evolution of abstract thinking: From induction and abduction to abstraction and deduction. quot;The power of thinking is knowing what not to think about.quot; 6. About the difficulties in overcoming psychological complexes. The story about the development of the concept of number: From “positive” to “negative”, from “rational” to “irrational”, from “real” to “imaginary” and “complex.” 7. What is there between the atoms? Does the world consist of particles or waves - or maybe something else? The historical debate from Thales versus Pythagoras via Newton versus Huygens to Einstein versus Bohr and Heisenberg and the break-up of the particle concept (super-string theory).
  24. 24. Nine Mathemagic Stories 8. The mysterious law about the degradation of work: The principles of energy and entropy. The development of the energy concept from Leibniz via Rumford and Carnot to Maier, Joule and Bolzmann. 9. The story of the long-lived demon that was unable to forget. Maxwellʼs demon and the deep connections between information theory and thermodynamics.
  25. 25. Ongoing mathematical ILE work at KMR • Virtual Mathematics Explainatorium with Conzilla • Interactive geometrical constructions with PDB • Interacting with mathematical formulas • using LiveGraphics3D / Graphing Calculator • Mathemagic component archive in Confolio • CyberMath: a shared 3D ILE for exploring math
  26. 26. Seven different Knowledge Roles in a KM • Knowledge Cartographer • constructs context-maps. • Knowledge Librarian • fills context-maps with content-components. • Knowledge Composer • combines content-components into learning modules. • Knowledge Coach • cultivates questions. • Knowledge Preacher • provides live answers. • Knowledge Plummer • connects questions to relevant preachers. • Knowledge Mentor • supplies motivation and supports self reflection.
  27. 27. The Conzilla “Mantra” Content in Contexts through Concept = Outsides of Concept Contexts = Inside of Concept Content Concept = Border between these
  28. 28. Conzilla ( Right-clicking on a concept or concept-relation brings up a menu with three choices: Contexts, Content, and Information. • Selecting Contexts opens a sub-menu, which lists all the other contexts where this concept or concept-relation appears. • Selecting Content opens a window (to the right) where the content-components of the concept or concept-relation are listed. • Pointing to a content-component brings up information about it, and double-clicking on a content-component opens another window where the content is shown.

  40. 40. 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).
