Abstract: Massive open online courses (MOOCs)  pose  a challenge  for  instructors  when  trying  to provide  personalised  support  to  learners, due  to  large  numbers of  registered  participants. Conversational agents can be of help to support learners when working with MOOCs. This article  presents  an  adaptive  learning module  for  JavaPAL,  a  conversational  agent  that complements a MOOC on Java programming, helping learners review the key concepts of the MOOC. This adaptive learning module adapts the difficulty of the questions provided to learners  considering  their  level of  knowledge  using item response theory(IRT)  and  also provides recommendations of video fragments extracted from the MOOC for when learners fail questions. The adaptive learning module for JavaPAL has been evaluated showing good usability and learnability through the system usability scale (SUS),reasonably suitable video fragments recommendations for learners, and useful visualisations generated as part of the IRT-based adaptation of questions for instructors to better understand what is happening in the course, to design exams, and to redesign the course content.
