Towards measuring learner's concentration in E-learning systems

Due to the advantages of e-learning platforms, many universities and schools around the world had adopted e-learning platforms in their educational systems. Students appreciate using e-learning platforms because of the advantages that offers like time flexibility, location flexibility and fast access to courses documents. However the major problem that they have with e-learning platforms is the difficulty to maintain concentration and focus during the learning time. The absence of teacher leads students to feel free to use phones, navigate in web sites, and play video games and by consequence they lose their focus and they couldn’t understand the course.In the traditional way of learning, teachers are face to face with students so they know how to keep them engaged in a lesson and how to get them back on track when they lose focus. Those ways used by teachers to keep students engaged are difficult to be implemented in e-learning systems. That’s why many studies had aimed this problem and try to find the best ways to implement those methods to maintain learners’ concentration during the use of e-learning platforms. There are many solutions under studies such as using cameras, brain waves, blood oxygen, heartbeat and blood pressure to detect when students are losing focus to activate an action to get the focus back. In this paper we will focus on the different methods for measuring students’ level of concentration.
