0. Good morning & thanks  Shift is happening! http://blogs.msdn.com/ukschools/archive/2008/02/18/shift- 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 www.teachers.tv/video/19119www.teachers.tv/video/19119 www.adrianoldknow.org.ukwww.adrianoldknow.org.uk Tracker 2 free software: http://www.cabrillo.edu/~dbrown/tracker/http://www.cabrillo.edu/~dbrown/tracker/

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 www.teachers.tv/video/154

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?
