Abstract
University courses pertained to data-science subjects typically involve students′ presentations. However, due to the temporal limitation of the courses, all student attendees may not be allowed to have their opportunities of presentations. This paper introduces a method in which all students give their presentations by utilizing a video-sharing-site. Furthermore, a double-blind mutual evaluation was attempted to ensure the perceived fairness of evaluation and students′ active engagement in the question and answer section. These detailed methods are described and their potential effects are discussed.
