From the colMooc website:
"The objective of colMOOC (www.colmooc.eu) is to develop and implement a collaborative tool capable of boosting participation among students and reducing the drop-out rate in learning through MOOCs. The conversational agent will intervene in the chats or student forums of the MOOCs platforms, pose challenging questions, trigger constructive dialogues between students and stimulate critical thinking and therefore deeper learning."According to colMOOC, three prototypes of the above-mentioned conversational agent on three different platforms will be tested.
