0. Good morning & thanks

Shift is happening!

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

Henry Cort – video analysis from Sport

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
