GeoGebra in Teaching and Learning

Using the GeoGebra apps in teaching/learning

I used the GeoGebra app to teach slope, graph and dilatation in class VIIIB. Following are benefits:

This handy geometry package is free, cross platform, and very easy to use. It allows for the creation of geometric objects, which have various properties (including position, color, size, etc…)

 Geogebra is useful in a wide variety of different contexts and branches of mathematics. When students are using dynamic geometry software, such as Geogebra, they invariably end up with a deeper understanding of the material (Pütz 2001).  This is probably because they are given a strong visual representation of the object,that comes associated with a more tactile impression that comes with using the mouse to move and adjust the object.  Obviously there is a "wow" factor involved in the use of the program, where the students are engaged with an activity simply because it is new, but it has been my experience that the use of these geometry packages ends up leading to a long lasting understanding of geometry.

Another advantage of Geogebra is that it allows the user to export the current file into a web .  This provides the ability for students and teachers to discuss and analyze each other’s work, and allows for the creation of a social discussion about the work. 

Geogebra also allows a "construction protocol navigation bar" to be added to the file, which means that users can step the geometric construction process, one piece at a time.  This is a tremendous advantage of Geogebra as it allows a user observing someone else’s work to have some insight into the process they went through to create it. 

Geogebra allows students to actively and through the sharing of the work online, socially construct an understanding of geometry.  This program allows for simple visualizations of possibly complex geometric concepts, and helps enhance a student’s understanding of those concepts.
