Who else could participate in my lesson plans?

This paper introduces the iTEC SDE (Scenario Development Environment), a recommendation system to assist teachers in the creation of lesson plans. A key functionality of the SDE is the recommendation of people. Basically, taking into account new pedagogical approaches, this system manages information about potential lesson plan contributors and provides recommendations on the best available people to participate in specific learning activities. The SDE has been developed as a multi-criteria recommender focused on supporting learning activities in particular technological and educational contexts. In this way, it manages information about the devices and applications available in the classroom and the features of the students, such as educational level, language, age, location, etc. The final goal of this system is to support teachers creating lesson plans in which they can develop new pedagogical approaches involving new technologies and external resources, such as people from outside the school. Eventually, this will contribute to engage students and improve learning.
