This profile is captured in a "Common European Framework" which can be seen as a means ...

During the mid 90s this issue was not highly developed. Existing researches in this field highlighted that it was important to anticipate proof with an argumentation activity that could support students to overcome some difficulties involving the construction of proof. The hypothesis of these researches was that there would usually be a continuity, named "cognitive unity", between these two processes. Nevertheless, the theoretical framework of reference did not provide tools to validate this. ...
