Flow chart depicting the operation of an ALS following our guidelines. From the beginning of the interaction until the last stage is finished, the ALS measures the students’ learning states, and provides them different styles of tasks (area A), to which it integrates feedback based on our engagement models (area B) according to the current adaptation stage (initial: area B.1; medium: area B.2; or later: area B.3). While formulating the feedback, the system verifies if engagement increased since the last intervention so that it decides to rephrase questions or to propose other discussion topics
