Resumo: |
The theme of this research arose during observations made in the classroom, and also after attending classes in TIC ( Information and Communication Technology) in the course for Professional Master s Degree at the Pontifícia Universidade Católica if São Paulo. The aim of the work is to relate mathematics classes with the technology presente in the daily lives of our students. It proposes a sequence of activities which would help and lead tothe pupils obtaining the natural rest of an inexact division with the calculator. The euclidian division is a procedure that makes it easier for pupils to find the natural rest working with the calculator of their mobile phones. In this research we performed a study with a group of fifteen pupils in the senior high school of a state school. We worked with diagnosis an intervention. The data collected were analyzed in the light of some presppositions of Didactic Engineering, and while the activities were being carried out, we realized that the difficulties of some students in regard to the operation of division, especially and to obtain the natural rest, appeared when they had to work with the calculator with natural numbers. However, these difficulties were decreased with the sequence of activities proposed. This work contributed to the students learning and showed that the calculator is a worthy ally in the educational process in addition to recovering some concepts about division of natural numbers. It taught the pupils to work with the calculator in the universe of natural numbers and to obtain the rest in an operation of inexact division |
