Hop-o' my Thumb and maths education
Abstract
In the new world of information and communication new students come into classrooms and universities with a different relation with knowledge. Teachers' roles become more brokers' roles leading to use and to give sense to knowledge much more than transmitting it. Different didactical tools take into account the new paradigm of teaching; particularly, the documentational genesis which is interested in the process of acquisition and transformation of resources into the teachers' documentational system of resources. On an other hand, the notion of didactic incidents should give tools to analyze the modifications of class dynamics and to better understand the students and teacher's joint action.
