Reflections on Enrollment Numbers and Success Rates<br />

at the openHPI MOOC Platform<br />

Christoph Meinel, Christian Willems, Jan Renz and Thomas Staubitz<br />

Conclusion and Future Work<br />

The paper at hand highlights the insufficient clarity and<br />

missing comparability of MOOC offerings from various<br />

platforms (i.e. openHPI vs. Coursera vs. Udacity) and<br />

shows the effect of these numbers on the expressiveness<br />

and validity of completion (or success) rates. We raise the<br />

question of how to count enrollments for courses with a<br />

massive audience and suggest abolishing the need to enroll<br />

for a course before being able to (at least passively)<br />

preview content. The obligation to enroll for a course<br />

would be necessary at the point when a participant wants<br />

to use active course content (i.e. quizzes) and contribute<br />

to the forum. Another point for further investigation is<br />

the definition of an active user and the differentiation between<br />

those, lurkers and enrolled users who never show<br />

up – including the analysis of reasons for enrollments that<br />

happen but are never used. openHPI defines an active<br />

participant as a user who submits at least one mandatory<br />

homework assignment or contributes to the discussion<br />

forum, but admits that this definition is slightly arbitrary<br />

and no better or worse than many other imaginable definitions.<br />

The analysis of our students’ engagement over the term<br />

of courses points out the importance of the first and second<br />

course weeks (at least for the overall duration of seven<br />

weeks as in the openHPI course model) when it comes<br />

to course design and instruction. Future work should<br />

investigate the validity of these numbers for longer (or<br />

shorter) course terms and find suggestions for course designers<br />

on how to keep up users motivation from the start.<br />
