      abstract = {Teacher facilitation of CSCL activities is widely  recognized as one of the main factors affecting student  learning outcomes in formal face-to-face settings. However,  the orchestration load that such facilitation represents  for the teacher, within the constraints of an authentic  classroom, remains under-researched. This paper presents a  novel method to estimate the cognitive load of teachers  during facilitation of CSCL sessions, using mobile  eye-tracking techniques. Throughout three studies of  increasing authenticity, we demonstrate the feasibility of  this approach, and extract insights about classroom  usability challenges in CSCL practice: the increased load  of class-level facilitation, or the real-time monitoring of  students’ progress. This new instrument in the CSCL  researcher’s toolkit can help focus our attention in  critical, fine-grained classroom usability episodes, to  make more informed design decisions.},
