"Developing tools in iGeom: Using the dynamic geometry in the classroom and distance learning"

In this work, we present the development of tools on the software iGeom - Interactive Geometry on Internet, which can be used for teaching and learning Geometry. We highlight the features that simplify the integration and the use of the iGeom in distance education through Internet mainly. Presently, this kind of program is well known and the Geometry it allows is usually named Dynamic Geometry. Concisely, a Dynamic Geometry software is the computational implementation of the ruler and compass. It allows the user to drag objects and to automatically redraw the whole construction while preserving their mathematical properties. We focus three features among the main developed ones: the communication, the authoring and the automatic checking of exercises. These resources simplify the teacher¿s task, when integrated into a learning management system. With them, the teacher can create exercises directly on the Web leaving to the software the task of checking each student¿s answer. Moreover, the student can have, in real time, an evaluation of his own performance.
