Overview
The role of technology in learning The role of gesture in teaching,
learning, and communicating New tools for teaching with
gesture

Educational Technology
Want students to do computer-based learning Individualized lessons Immersive visualizations Interactive and in-depth explorations Independent learning experiences
![Page 4: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/4.jpg)
A Conjecture
Students will (first/primarily) use the resources that their teachers teach with
Teachers have to teach with (the same) educational technology
![Page 5: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/5.jpg)
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
![Page 6: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/6.jpg)
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
![Page 7: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/7.jpg)
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
![Page 8: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/8.jpg)
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

The Role of Gesture in Mathematics
Some mathematical concepts are physical – fictive motion (Núñez) Approaching limits How can this be described without
gesture?

Classroom Teaching
Want to… Engage students Have eye-to-eye contact Create dynamic visualizations Simultaneously perform
relevant/required gestures
![Page 11: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/11.jpg)
Teaching with Technology
End up… Concentrating on PC screen Talking into the PC Focusing on the mouse/keyboard
interface Disengaging from the class

Keys to Teaching with Technology
Non-intrusive interface
Flexible material presentation
![Page 13: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/13.jpg)
Gesture Friendly Interfaces
Low-cost/low-tech solution
Viable in most computer-equipped classrooms
![Page 14: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/14.jpg)
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
![Page 15: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/15.jpg)
GFI Example
Choosing a Cell Phone Plan – Lines and Intersections
![Page 16: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/16.jpg)
Designing Flexible Material
Primary complaint of learning objects from pre-service teachers is that the material cannot be built up towards the final state
![Page 17: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/17.jpg)
Inflexible Example
Fun and Sun Rent-A-Car http://

Flexible Example
Choosing a Cell Phone Plan – Data Collection
![Page 19: Gesture Friendly Interfaces and other Tools to Help Teachers Teach with Gesture](https://reader036.vdocuments.net/reader036/viewer/2022062519/56814cf9550346895dba0a46/html5/thumbnails/19.jpg)
Improvements
Flexible design allows incremental in-class teaching
GFI makes whole-class, face-to-face teaching possible
New learning object provides corrective feedback

Digital Mathematics Performances and GFIs
How will teachers be trained to use GFIs?
Key features are physical, so key training likely visual

Summary
Gesture is an important part of teaching and learning
Classroom presentation is an important part of learning object design
