MarkC: A teacher student at UTS

I have created the movie demonstrating the use of using graphical calculator on my mobile phone. The following things were used

• Mobile phone with J2ME and Symbian OS. I used my Nokia 6120c mobile with bluetooth connectivity
• Math4Mobile application Graph2Go and Solve2Go
• Nokia PC Suite software to connect PC to mobile
• Mobiola Screen Capture to record the mobile to a video (trial version)
• Windows Movie Maker V6.0 to edit and add narration (with Microsoft Vista OS)
• AntonyPranata.com Screenshot for Symbian OS (freeware), shown below is a screenshot showing the actual quality

Cubic equation (ax³+bx²+cx+d=0)  for x³-x²-5x+2 (where a=1, b=-1, c=-5 and d=2) showing minima, maxima and infexion points.

This can be used to verify and visulise calculations. Paramaters can be changed on the fly to learn effect.

Online presentation by the author – showing how earnest he is in condemning the way digital technology has made the current generation mentally deficient. He feels that teenagers are no longer engaged in subjects such as history, litaracy and civics and that they are more focussed on the ME rather than as members of society.

A lot of the responses from younger members are very critical of his ideas and the fact that he is using digital medium as amethod of communication.
