Recognition of emotions to support teaching didactics

In order to improve students' learning, which will enable them to acquire the competences required for graduation, there is a need to know how they learn and which didactic and teaching activities lead to effective learning and comprehensive training. This highlights the possibility of monitoring classroom didactic action through ICT tools, in order to show which teaching activities can be valid and how learners receive and perceive the training process. This facial recognition can be done in a natural way by people in a context of evaluation of affective expressions, which are framed in six basic emotions, namely: fear, sadness, joy, anger, disgust and surprise. This opens up expectations for gathering information and creating knowledge, which allows for adjusting the teaching and learning processes related to higher technical and vocational education.
