Abstract: The existing differences between Open Distance Learning (ODL) and traditional face-to-face teaching modes result in various difficulties associated with ODL education, such as low knowledge delivery efficiency. One of the leading challenges is that, lecturers (educators) may not be in a position to receive the students’ feedback in time, and consequently leading to a negative impact in teaching materials modification and styling efficiency. The burgeoning Brain Computer Interface (BCI) created the possibility of assessing the activities of the working memory, which is closely related to the knowledge accepting (i.e., learning and understanding) efficiency. This paper aims to build a real-time learning efficiency assessing system, based on the technique of electroencephalograph (EEG), a kind of non-invasive BCI. The activities of working memory is detected by the system when students are studying, based on either the lecturers’ or the students’ side, according to the priority in learning materials and styles modifications. This creates a relatively higher efficiency of knowledge delivery.
