Main objective

The main objective of this practicum is the collection and creation of GeoGebra investigations and demonstrations as well as the creation (and collection) of some on-line videos to support them.

These activities will be used to teach functions (see unit aims here) to secondary school students in different classroom situations. I will be using them with my own students at LAS in Switzerland, but I will also gather feedback from other teachers collaborating in the project.

If you would like to collaborate, please contact me directly. You can collaborate actively, creating some activities and sharing them within the project or passively by just using the activities and giving us feedback. This second option involves very little time from your part.

GeoGebra is an interactive geometry, algebra, and calculus application, intended for teachers and students. Most parts of GeoGebra are free software. GeoGebra is written in Java and thus available for multiple platforms.

GeoGebra is dynamic geometry software. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly on screen, or through the Input Bar. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra to make conjectures and prove geometric theorems.

There is a pool of free educational resources and dynamic worksheets hosted on the website.

All materials can be downloaded free from the organisation's website: http://www.geogebra.org

This includes a multi-lingual forum with help: http://www.geogebra.org/forum

A list of institutions using it officially: http://www.geogebra.org/cms/institutes. Local GeoGebra Institutes are groups of teachers and researchers at schools and universities who support students and teachers in their region. As part of the International GeoGebra Institute network they share free educational materials, organize workshops, and work on projects related to GeoGebra. A list of their events can be found here: http://www.geogebra.org/cms/events

And a very important resource: http://www.geogebratube.org. GeoGebraTube is the official repository of GeoGebra constructions and GeoGebra related resource, where I plan to collaborate with other teachers.

GeoGebraChannel is a youtube-based video collection.
