  1. Gesture Friendly Interfacesand other Tools toHelp Teachers Teach with Gesture Stephen Chen School of Information Technology

  2. Overview • The role of technology in learning • The role of gesture in teaching, learning, and communicating • New tools for teaching with gesture Institute for Research on Learning Technologies

  3. Educational Technology • Want students to do computer-based learning • Individualized lessons • Immersive visualizations • Interactive and in-depth explorations • Independent learning experiences Institute for Research on Learning Technologies

  4. A Conjecture • Students will (first/primarily) use the resources that their teachers teach with • Teachers have to teach with (the same) educational technology Institute for Research on Learning Technologies

  5. Classroom Option 1 • Computer lab with individual instruction • Most tools designed with this assumption • Expensive and inefficient • Still want occasional face-to-face, whole-class teaching in this environment Institute for Research on Learning Technologies

  6. Classroom Option 2 • Presentation PC and projector • Educational tools not often designed for this environment • Leads to poor presentation of material and technology • Interface design not suited for classroom teaching and gesture production Institute for Research on Learning Technologies

  7. The Role of Gesture in Communication • Some ideas are best expressed with gesture (Kranstedt, Kühnlein, and Wachsmuth) • Inability to gesture can lead to interference of speech production (Mayberry and Jaques) • Increases complexity of spoken description Institute for Research on Learning Technologies

  8. The Role of Gesture in Teaching • Students learn better with gesture (Goldin-Meadow, Kim, and Singer) • Matching gesture improves uptake (compared to speech alone) • Mismatching gesture disrupts uptake • Students may uptake incorrect strategy communicated by gesture Institute for Research on Learning Technologies

  9. The Role of Gesture in Mathematics • Some mathematical concepts are physical – fictive motion (Núñez) • Approaching limits • How can this be described without gesture? Institute for Research on Learning Technologies

  10. Classroom Teaching • Want to… • Engage students • Have eye-to-eye contact • Create dynamic visualizations • Simultaneously perform relevant/required gestures Institute for Research on Learning Technologies

  11. Teaching with Technology • End up… • Concentrating on PC screen • Talking into the PC • Focusing on the mouse/keyboard interface • Disengaging from the class Institute for Research on Learning Technologies

  12. Keys to Teaching with Technology • Non-intrusive interface • Flexible material presentation Institute for Research on Learning Technologies

  13. Gesture Friendly Interfaces • Low-cost/low-tech solution • Viable in most computer-equipped classrooms Institute for Research on Learning Technologies

  14. Designing GFIs • Pick an important feature of the learning object that will be highlighted during a classroom presentation • Develop a simple way to control this feature Institute for Research on Learning Technologies

  15. GFI Example • Choosing a Cell Phone Plan – Lines and Intersections Institute for Research on Learning Technologies

  16. Designing Flexible Material • Primary complaint of learning objects from pre-service teachers is that the material cannot be built up towards the final state Institute for Research on Learning Technologies

  17. Inflexible Example • Fun and Sun Rent-A-Car • http://math.rice.edu/~lanius/Algebra/rentacarja.html Institute for Research on Learning Technologies

  18. Flexible Example • Choosing a Cell Phone Plan – Data Collection Institute for Research on Learning Technologies

  19. Improvements • Flexible design allows incremental in-class teaching • GFI makes whole-class, face-to-face teaching possible • New learning object provides corrective feedback Institute for Research on Learning Technologies

  20. Other Tools • Digital Mathematics Performances • http://www.atkinson.yorku.ca/~sychen/research/math/DMP.html Institute for Research on Learning Technologies

  21. Digital Mathematics Performances and GFIs • How will teachers be trained to use GFIs? • Key features are physical, so key training likely visual Institute for Research on Learning Technologies

  22. Summary • Gesture is an important part of teaching and learning • Classroom presentation is an important part of learning object design Institute for Research on Learning Technologies
