RESUMO

The aim of this dissertation is to investigate how 6th grade elementary school students solve problem-situations involving whole numbers whilst working with the Aplusix software. Our research was developed in an elementary school from the public education systems of the state of São Paulo, located in the outskirts of the western region of Sao Paulo, where an equipped computer lab was available. 8 students from a class of 34 who were able to stay in the premises after school hours participated in the study. In this research, we aim to investigate how learners convert problems presented in their mother tongue register into the symbolic register using Raymond Duvals theoretical framework of semiotic representation. The students were observed to be both motivated and interested as they worked upon the computer-based activities throughout the project. No major difficulties in handling the program tools were apparent. There is strong evidence in the protocols to suggest that the problem involving a card game had a better percentage of correct results than the problem involving the dislocation of floors in a building. We believe that card games are more familiar to the learners. In addition, it was observed that most of the difficulties presented by the students when solving of the problems were due to errors in the adding and subtracting calculations involving whole numbers. There was a joint effort between the researcher and the teacher which proved to be extremely important since it allowed the teacher to diagnose the students difficulties and to focus her teaching strategy in a more meaningful way
