	abstract = {<p>Our on-going EU project aims at facilitating the acquisition of science concepts through videos, especially also through the creation of videos on the part of the learners themselves. In this study, we explore the potential of text-analytic method to identify and characterise problems of understanding using Khan Academy videos as examples. Several patterns that characterise specific problem types could be identified. These will later be used for monitoring interactions around videos on the JuxtaLearn platform.</p>
