  1. ICT bringing mathematics to life and life to mathematics Adrian Oldknow Emeritus Professor: The University of Chichester, UK Visiting Scientist: INSPEM, Universiti Putra Malaysia www.adrianoldknow.org.uk aoldknow@yahoo.co.uk

  2. 0. Good morning & thanks • Shift is happening! http://blogs.msdn.com/ukschools/archive/2008/02/18/shift-happens-and-freezing-frogs.aspx

  3. 1. Introduction • ICT and teachers • ICT and schools • ICT and learners • ICT and young people

  4. 2. Mathematics & snapshots • Digital images – democracy • Software to manipulate images • Math software to import images • Analysis with images:measures/geometry

  5. Where’s this? Open file

  6. Open file

  7. Open file

  8. 3. Mathematics & video clips • Digital video – democracy • Software to manipulate video • Physics software to import video • Analysis with images – data/algebra

  9. Curriculum enhancement - STEM Henry Cort – video analysis from Sport www.teachers.tv/video/19119www.adrianoldknow.org.uk Tracker 2 free software: http://www.cabrillo.edu/~dbrown/tracker/

  11. 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

  12. 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!

  13. 5. Modelling motion with real data • Simple, reliable, cheap technology • Experiments easy, safe, cheap • Immediate feedback • Data and graphs -> analyze

  14. Curriculum enhancement data-logging: CBR and distance-time graphs www.teachers.tv/video/154

  15. Some parabolas? Can you see the elephant?

  18. 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.....

  19. What can we do with rockets? Airburst

  20. Mathematics is rocket science!

  21. Rocket science is childs’ play

  22. 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?

  23. Adrian Oldknow aoldknow@yahoo.co.uk • Thank you • Goodbye • Good conference • Good luck PS: Take some good snaps, too
