“…According to the work of Moura et al (2007), which analyzes the impact of iGeom and SAW in the learning process, the increased number of exercises given in the course is "… a consequence of the use of automatic assessment resources which have encouraged learners in their studies (in 2006, 82% of The experiments completed in MAC118 have shown that our algorithm is efficacious in checking exercises and efficiently runs in computers with low-processing capabilities. In 2004, the computers used in class had processors similar to a K6II 450 MHZ with 256 Megabytes of RAM memory.…”

“…During a two month period, they were instructed on how to use iGeom and SAW to construct e-courses for geometry, as well as how to benefit from the functionalities of dynamic geometry programs to create more interactive content for Web-based courses. In 2006 and 2007, a qualitative and quantitative analysis of SAW, using the iGeom program, was completed by Moura et al (2007), following the methodology proposed by Yin (2005).…”

“…Some of these are commercial, while others are freeware, including SAW (Moura et al, 2007), AulaNet (Lucena, Fuks, Raposo, Gerosa & Pimentel, 2006) and Moodle (Moodle, 2007). Usually, these environments lack specialized resources that would boost learning specific contents (e.g., geometry).…”

“…The main benefits of this approach include a program that is (a) fast enough to be used over the Internet to support the use of dynamic geometry programs in distance education courses; (b) able to check any kind of geometric construction and return whether the construction has the necessary properties to solve an exercise; and (c) able to run on computers with low-processing capabilities, which is very important in Brazil, where many computers used in public schools are out-of-date. Furthermore, we will present results using this algorithm, implemented on iGeom, together with an under-development learning management system, referred to as SAW (Moura, Brandão & Brandão, 2007). This paper is structured as follows: In section one, we will briefly describe the DG program, iGeom, compare its functionalities with other DG programs and outline its potential use when together with LMS.…”

One of the key issues in e-learning environments is the possibility of creating and evaluating exercises. However, the lack of tools supporting the authoring and automatic checking of exercises for specifics topics (e.g., geometry) drastically reduces advantages in the use of e-learning environments on a larger scale, as usually happens in Brazil. This paper describes an algorithm, and a tool based on it, designed for the authoring and automatic checking of geometry exercises. The algorithm dynamically compares the distances between the geometric objects of the student's solution and the template's solution, provided by the author of the exercise. Each solution is a geometric construction which is considered a function receiving geometric objects (input) and returning other geometric objects (output). Thus, for a given problem, if we know one function (construction) that solves the problem, we can compare it to any other function to check whether they are equivalent or not. Two functions are equivalent if, and only if, they have the same output when the same input is applied. If the student's solution is equivalent to the template's solution, then we consider the student's solution as a correct solution. Our software utility provides both authoring and checking tools to work directly on the Internet, together with learning management systems. These tools are implemented using the dynamic geometry software, iGeom, which has been used in a geometry course since 2004 and has a successful track record in the classroom. Empowered with these new features, iGeom simplifies teachers' tasks, solves non-trivial problems in student solutions and helps to increase student motivation by providing feedback in real time.
