U_MOOC_Countries_of_Participants_2018On Tuesday, March 27, 2018 the web course Estimation of Measurement Uncertainty in Chemical Analysis was launched the fifth time as a MOOC (Massive Online Open Course)!

Currently more than 450 participants from 70 countries are registered! As was the case in the previous years, the majority of participants are from analytical laboratories. This once again demonstrates the continuing need for training in measurement uncertainty estimation for practicing analytical chemists.

The full course material is accessible from the web page https://sisu.ut.ee/measurement/uncertainty. As is usual, some developments and improvements have been made to the course material. in particular, the description of course organisatsion was improved; more explanations and examples were added on random and systematic effects within short and long term; the typical requirements for determining repeatability and within-lab reproducibility have been clearly outlined; more explanations on the main principles of modifying a model in a modelling approach have been given, together with an example. Some changes are still in the pipeline.

The course materials include videos, schemes, calculation files and numerous self-tests (among them also full-fledged measurement uncertainty calculation exercises). In order to pass the course the registered participants have to pass six graded tests and get higher than 50% score from each of tehm. These tests are available to registered participants via the Moodle e-learning platform.
