Good morning and welcome Apologies for my lousy Powerpoint skills Many thanks to TI for: Supporting this conference Making this fantastic technology Making the last 20 years of my life so much fun! And it still gets better.... And thanks to you for coming along.

I guess we know, and are still learning, what TI- Nspire Technology is? But what do you understand by STEM? And why should it be integrated? (Hint: State of the Union) Not: S TE M – but maybe SMarT Our countries need SMarT schools and teachers

I’ll take examples from schools developing cross- curricular cooperation to make the subjects more joined-up and engaging for all. Sports and Toys for Enjoyment & Motivation

Format of today’s session: First: plug the books! Second: the links are on the handout but e-mail me if you want a copy with live links aoldknow@yahoo.co.uk Third: there will be some data-logging, video capture and geometry using both TI-Nspire and some other technologies. Ready to go?

A mental starter a)9.8, 9.8, 9.8, 9.8,..,..,.., b)1, 2, 3, 4, 5,..,..,.., c)1, 4, 9, 15, 25,..,..,.., d)1, 2, 4, 8, 16,..,..,.., e)1, ½, ¼, 1/8, 1/16,..,..,.., In each case predict the next 3 values, sketch a graph, use a name to describe the process, think of an experiment which might give data like this.

How fast did Sophie go?

Guess where?

Can you estimate the date of the photos – and the speed of the Jag?

CUT 7 http://www.jagweb.com/jaguarmodelclub/cut7.htm Jaguar E-Type 3.8 Competition Coupe Sold £295,625 - Feb 2005 http://en.wikipedia.org/wiki/Jaguar_E-Type Length = 4.7 m. Low-drag Mk1 concept – Lord Cowdray

Digital camera at 210 fps You could estimate speeds by single- stepping frames e.g. In Media Player

Sophie in the snow: SSR Enough information to estimate coefficient of friction!

Sophie’s run modelled in TI-Nspire

GPS sensor in Logger Pro Where was I and what was my journey?

Logger Pro’s triggered data logging, synchronised with video capture

So what can TI-Nspire CX do? That’s just a glimpse of PublishView for you!

Working with images – TI-Nspire CX

How a telescope works And a torch, too!

Teachers TV Hard to Teach - quadratics http://www.teachers.tv/videos/quadratic-equations http://www.teachers.tv/videos/quadratic-equations TDA used the idea for recruitment posters on the London underground and buses.

What sorts of motion here?

STEM is fun and it is all our future
