The indicator of cognitive diversity in project-based learning

The development of ICTs has emerged several electronic platforms, which contributed to a new mode of digital learning: E-learning. Moreover, new pedagogical approaches have been adopted, based on group learning, including project-based teaching. Project-based learning is an active learning method, based on group work to develop skills and build knowledge. However, the group of learners is faced many challenges during the project, such as decision-making. the decisions by group , generate convergences and diversitys between the members, due to cognitive conflict. Our approach in this paper is to treat the cognitive conflict in the group of students, by measuring the cognitive diversity indicator concerning the concepts of project, in decision making situations. Key-Words: Project-based learning, analytical hierarchy process, decision-making, cognitive map, Shannon entropy, cognitive diversity indicator.
