Acoustic Monitoring System for Teacher and Student Engagement Evaluation

Face-to-face learning activities involve multiple acoustic interactions between students and teachers. These interactions provide information about their level of engagement with the educational activity. Hence, the acoustic interaction between the different actors in a classroom produces relevant information to evaluate their performance in a quantitative and qualitative manner. Traditionally, this information is collected through surveys and interviews. Technology is rarely used to record learning sessions due to the cost related to the installation of the equipment and the complexity of the analysis of the recordings. Here, we developed a web application that guided different types of student-teacher interaction during a class. The application recorded all the acoustic interactions and labeled the information so that subsequent analysis of the information can be efficiently processed.
