This is a quick guide to the free software iGraf: Interactive Graphics on the Internet. iGraf is specially designed to help teachers and students with an important Math concept, function. This software has several advantages, such as:

• Free - iGraf is free of charge to any user and can be donwloaded from the iMath website.
  
• Portable - iGraf is written in Java programming language and, thus, it can work in any environment where such technology is available. It's very likely that you are visualizing this guide in a Java capable web browser and, if it is not the case, you can download the necessary files to this (the JRE) also free of charge. In the section running iGraf you can find a bit more explanation about how to install iGraf and Java.
  
  
• Advanced Resources - The iGraf has some exclusive features (until now not simultaneously available in any other similar system).
• With iGraf is possible to explore function concepts in a dynamic fashion, through its function animations.
• There are some features to simplify the teacher's job, especially with large classes of students. The iGraf allow teachers to create and publish on the Web exercises with automatic evaluation!
  If the school has a Learning Managment System (LMS) in its Web server, there are much more gain, since iGraf could be integrated to the LMS, providing reports to the teacher and feedback to the students activities. Our team also makes avaliable a free Moodle package to integrate iGraf, and others interactive Learning Modules (iLM), called iAssign.
  To the students, automatic evaluation is interesting because provides an immediate feedback. This feature allows students to get know if their exercise answer is in accordance with teacher's expectation.
  
  
• Easy - The main features of iGraf is very simple to use and all of its options is available under Web pages.

The iGraf development was initiated in 2003, as a Scientific Enhancement study the prospective teacher Reginaldo do Prado at the IME-USP, under my supervision. In 2004, was tested the first version of iGraf.

Our goal is to create and release high quality didactic stuff (mainly software) to students and teachers in all levels. Very soon iGraf will have its source code distributed under the CCSL.
We hope this guide can be usefull for you!
