Keynote

Michael Borcherds aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Conference Schedule
** Presentation Tuesday around 7:00 PM ** (after dinner but before dessert :)

Mike Borcherds has been using Dynamic Mathematics since he started teaching in 1995 and in 1996 he wrote a simple program for an obsure British computer called the Acorn Archimedes which he then updated to run on the Apple eMate and Windows.
 * == [[image:zMikeBorcherds.png]] == || **Brief Biography;**

As relative latecomer to GeoGebra - he started using it seriously in 2007 and added a few simple things to GeoGebra 3.0 (eg right-dragging to move objects, Polynomial command, decoration for angles and parallel lines) that he wanted for his own purposes.

He was then in charge of the GeoGebra 3.2 release and added almost all the features listed in the release notes although Markus helped a lot when he was stuck and he's also changed quite a lot behind the scenes and fixed lots of old bugs (and some of Mike's!).

GeoGebra 4.0 is very interesting because the programming team now have a proper team of developers working on various areas (Mathieu: 3D, George: Spreadsheet, Florian: GUI, Yves: Intergeo, Markus: CAS) all of whom have their own interesting ideas to add. This summer, there are also got 5 students working from Google Summer of Code.

NEW: **At his keynote speech, Mr. Borcherds gave us a puzzle on paper to solve. One of our workshop participants made a GeoGebra worksheet and solved it there. Here is the pdf/docx of the puzzle and here is Diana Braun's page - don't worry the solution isn't shown until you check the boxes! **

Here are some recent creations in GeoGebra: @http://www.geogebra.org/en/wiki/index.php/Amazing_Applets

Mr. Borcherds also particularly interested in creating randomized worksheets which give feedback to students to let them take more control of their learning (He has written 30+ similar to this) @http://www.geogebra.org/static/mathlets/LinearGraphs/index2.html?level=0

He has also designed the infamous GeoGebra tie: [] ||
