A interação dos estudantes em um ambiente informatizado de aprendizagem matemática : uma experiência dentro do projeto um computador por aluno - UCA.

This qualitative study aimed to investigate the interactions through the use of educational laptop Projeto Um Computador por Aluno – UCA in mathematics classes. The participants were students in a class in the 9 th grade in a public school in the city of Belo Horizonte - MG. The field research was developed from September to November 2012. The research methodology used for data collection was the case study, and data recording using several instruments record data: the researcher's field diary, written activities developed by the students, files with the constructions made in the laptop and the audio recordings and video. The mathematical content in the activities using the laptop and software GeoGebra and KSpread ranged from the construction of tables and graphs, the functions of the 1st and 2nd degrees, the length of the circumference and area of a circle. The data analysis from participant observation, written records and files with the constructions made in the software, showed that the use of the laptop in the classroom can facilitate the creation of a fertile environment for promoting the learning of Mathematics. On some occasions students interacted with their peers during activities involving the use of laptop. The dialogues between students while solving the activities enriched the learning environment in mathematics. It was possible to observe the interaction between the students and the teacher-researcher, it was also observed that in many situations the students were so engaged in front of the laptop screen, solving activities individually. Finally, some challenges for the conduct of activities in computerized learning environments mathematics are presented.
