1. Introduction
ICT and teachers
ICT and schools
ICT and learners
ICT and young people
2. Mathematics & snapshots
Digital images – democracy
Software to manipulate images
Math software to import images
Analysis with images:measures/geometry
Where’s this?

3. Mathematics & video clips
Digital video – democracy
Software to manipulate video
Physics software to import video
Analysis with images – data/algebra
Curriculum enhancement - STEM

4. Mathematical modelling and visualization in 3D
We live in a 3D world
Computer realism – virtual worlds
Maths does little for 3D after age 11
Exercise mental muscles
Importance of constructional toys
Cabri 3D can:
Improve students’ (& teachers’) ability to visualise in 3D
Allow students to model static and dynamic 3D objects
Relate descriptive, transformation, and coordinate geometry
Measure lengths, areas, volumes.. Let developers create ‘manipulatives’
with which all can experiment – free!
5. Modelling motion with real data
Simple, reliable, cheap technology
Experiments easy, safe, cheap
Immediate feedback
Data and graphs -> analyze
Curriculum enhancementdata-logging: CBR and distance-time graphs

Someparabolas?
Can you see the elephant?

6. Putting the ideas together – is it rocket science?
Al Fresco: Accessible, Lively, Fun, Reliable, Easily set up, Safe, Cheap, Open-ended
Estimation, Measurement, units .. Dynamic: velocity, acceleration Algebra: based on average speed Graphs: trajectory, flight length Historic: Galileo, Newton... Relevant to their world: phone, TV,
web, GPS.....
What can we do with rockets?
Airburst
Mathematics is rocket science!
Rocket science is childs’ play
7. Conclusion
We have the technology
Our students know how to use it
Can we as educators unlock its potential?
Can we afford not to?

Thank you
Goodbye
Good conference
Good luck
PS: Take some good snaps, too
