Phases of digital technologies in the mathematical exploitation in a classroom: from graphic calculators to intelligent cellulars

Abstract

This paper reports researches related to the use of Technologies in mathematical exploration in different phases of digital technologies. These phases begins in the eighties and go through these days, in a way that each phase is not separated from the other. For this purpose, we emphasize one activity, which was investigated in different media like graphic calculators, computers and smartphones, discussing the possibilities and limitations of each media. We stress that smartphones are the biggest trend in digital technologies in Basic Mathematics Education. With the discussion carried out we point that the success of one activity with the use of technology is related to its preparation, when it favours the investigation and creation of conjectures to the students. Besides, factors like lack of teacher training to the use of technology when teaching Mathematics, rigid curriculum and difficulties while preparing activities with technologies create barriers to teachers.
