On Apr 16, 2014 the MOOC Estimation of measurement uncertainty in chemical analysis offered by University of tartu finished successfully. The course eventually had 270 participants from more than 40 countries. 141 participants successfully completed the course, making the completion rate 52%, which is very good for a MOOC, especially one that has quite difficult calculation exercises, which need to be done correctly for completing the course. Comparing to other MOOCs: completion rates around 10% and below are actually quite common with MOOCs as indicated by a recent survey).

The feedback was very positive (some examples) and we are glad that evidently we were able to offer something that is really needed by people who do chemical analysis in their everyday work, as many of our participants. The participants were very active and asked lots of questions. These were often very much to the point and addressed things that are really important to analysts in their everyday work. The course had several forums (general and by topic) and the overall number of posts to them during the course period reached beyond 300! (overall number containing posts from participants and teachers)

This active participation made teaching this MOOC a great experience also for us, the teachers. The discussion threads gave a lot of added value to the course and some of them triggered making important modifications to the course materials.

We plan to repeat this course again in Spring 2015.
