O uso de Ambientes Virtuais (AVs) não-imersivos em educação ainda não foi devidamente explorado e estudado, porém alguns autores já demonstram a diferença que a Realidade Virtual (RV) pode fazer no aprendizado. A linguagem Virtual Reality Modeling Language (VRML) é uma proposta para a introdução de AVs não-imersivos na internet; é uma linguagem independente de plataforma, que permite a criação de AVs por onde se pode passear, visualizar objetos por ângulos diferentes e com eles interagir. Assim, os estudantes podem beneficiar-se dessa tecnologia, pois ela lhes permite acessar objetos que descrevem assuntos e contextos do conteúdo abordado e informações verbal-escritas da disciplina, podendo manuseá-los. Este trabalho possui três partes: na primeira, investigam-se as questões que envolvem o uso de AVs no ensino-aprendizagem de matemática para o desenvolvimento dos aspectos cognitivos; as experiências e as condições necessárias para o uso dessa tecnologia na educação de matemática, como a construção do conhecimento e o desenvolvimento de aspectos cognitivos e lógico-matemáticos. Na segunda parte, propõe-se um modelo conceitual de um ambiente de aprendizagem para o ensino-aprendizagem de matemática, sendo, após, realizada a implementação do ambiente de aprendizagem proposto. A terceira parte reporta um estudo de caso, no qual um AV modelado em VRML é aplicado aos alunos de uma escola. Alguns dados dessa aplicação são levantados e analisados estatisticamente com o fim de se avaliar o desempenho do uso do protótipo no ensino-aprendizagem de matemática. / The use of non-immersive virtual environments in education has not been studied, as it should have been. However, some authors have already demonstrated the benefits coming from using such technology. VRML - Virtual Reality Modeling Language provides means for using virtual environments in the Internet. It is a platformindependent language that allows the specification of virtual environments where users can walk in, observe different objects and interact with them. Students can benefit from this technology, since it allows them to access objects describing subjects that students should study. This work is presented in three parts. In the first one, we investigate the use of virtual environments in math education for developing cognitive aspects, the experiences and necessary conditions for using this technology in improving logic and mathematical thinking. In the second part, we present both the conceptual model and the implementation of an educational tool intended to help in math education. The third part is a case study: we have developed a virtual environment using VRML, and it has been applied in math classes for 7th grade students. Data collected during this experiment has been analyzed statistically and some conclusions can be drawn based on those results, and observations.

This paper aimed to check whether there was a better student performance after Semiology Presentation Register being applied to Mathematics, that is, with regards to solving problems, natural numbers resolutions for the 6th grade fundamental school children at COLUN – Colégio Universitário (UFMA College School). The first task consisted of a list of exercises based on Semiology Presentation Register with ten problems aiming to measure students performance level. From the analysis of the data collected, a study plan was elaborated based on the mathematics book contents adopted by the school. During the research, several meetings were held with the students teacher to detect if there was any improvement on students performance, and thus adjust the way contents would be developed in the classroom on Presentation Register Theory applied to. In observing the daily classroom, several types of evaluations were made, such as single and groups exercises, in order to secure improvement and school performance. The applying of study, approach and semiology conversions, related to evaluation and classroom activities, were made at random in order to guarantee analysis’ data impartiality. As the research result it was found out that nearly 60% of students had suitable improvement (good: 61% – 80%) and 37% had fair improvement (fair: 41% – 60%). It was also found out that about 3% of students did not show any problem solution whatsoever. Those results show that it was possible to improve school performance on Mathematics for the researched students.
