Abstract
 
The purpose of this paper is to explore the characteristics of teaching assistants’ interventions in Massive Open Online Courses (MOOCs). The study of interaction patterns in MOOCs can inform the design and development of mechanisms for more effective learning. We performed an analysis of teaching assistants’ interactions in two different MOOCs in different subject matters (technology and humanities). The study revealed notable differences in the characteristics of teaching assistants’ interventions within the two courses, in terms of language used, length of messages, response time and length of discourse. The findings of this study provide us with useful insights on current human interventions in MOOC forums, driving our effort in designing future modules to support the large number of students of these courses, with the ultimate objective to improve the learning experience for each individual student of future MOOCs.
