First we intend to analyse if and how dynamic geometry software prove to be a communication space for students and how they support students towards proving. Second, we reflect about the use of video-tapes as source of information both for Mathematics Education research and for the teaching practice. In particular we approach the question: how do video-tapes help in the construction of a shared experience in the classroom? %G English %2 https://telearn.hal.science/hal-00190192/document %2 https://telearn.hal.science/hal-00190192/file/Olivero_2002.pdf %L hal-00190192 %U https://telearn.hal.science/hal-00190192 %~ TELEARN %~ TICE %~ TEL
