0. Good morning & thanks Shift is happening! happens-and-freezing-frogs.aspx
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? Open file
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 Tracker 2 free software:
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 enhancement data-logging: CBR and distance-time graphs
Some parabolas? 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?
Adrian Oldknow Thank you Goodbye Good conference Good luck PS: Take some good snaps, too
