Measurement_Uncertainty_MOOC_Successfully_FinishedOn May 18, 2017 the MOOC Estimation of measurement uncertainty in chemical analysis offered by University of Tartu finished successfully.
Eventually altogether 363 people registered (270 in 2014, 489 in 2015, 757 in 2016) from 69 countries (a number of participants joined after the start of the course). The significantly lower number of participants is understandably due to the fact that this year for the first time the certificate on paper was not free of charge. 219 participants actually started the course (i.e. tried at least one graded test at least once) and out of them 148 successfully completed the course (141 in 2014, 169 in 2015, 308 in 2016). The overall completion rate was 41% (52% in 2014, 34% in 2015, 40% in 2016). The completion rate of participants who started the studies was 68% (67% in 2014, 60% in 2015, 67% in 2016). The completion rates of participants who actually started the course are nicely consistent over the years and can be considered very good for a MOOC, especially one that has quite difficult calculation exercises, which need to be done correctly for completing the course.

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 has several forums (general and by topic) and the overall number of posts to them during the course period reached beyond 300 (!) (overall number of posts, both from participants and from teachers) and the forums are still active and posts are still coming in.

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, even during the course.

We want to thank all participants for helping to make this course a success!

We plan to repeat this course again in Spring 2018.

 

EACH_AMS_Master_Seminar_Spring_2017Today on Sat 20.05.17 the concluding event of the joint master seminar of the EACH and AMS programmes took place. Its main activities were the feedback session on employability from Prof. Salzer (TU Dresden) and concluding the Group work of helping a water production company to choose, which analytical technique to implement in their lab for analysis of trace elements in drinking water according to the EC directive 98/83/EC Quality of Water Intended for Human Consumption.

Prof. Salzer gave feedback on the CVs and motivation letters that the students wrote according to the guidance given by him earlier this week. He praised the group and gave, on the example of CVs and motivation letters of students, a number of good hints for improvements.

The above mentioned group work has been going on since the beginning of the semester and its essence is that students are divided into groups and each group is a small consultation company that intends to guide a water production plant, as to which trace element technique to implement in their lab, taking into account the amount of water produced, the corresponding required number of samples per year according to 98/83/EC, the cost of the equipment, the running costs, etc. The groups had to justify their recommendations. The groups did well and came up with different suggestions: GFAAS (together with CVAAS), ICP-OES (together with voltammetry) and ICP-MS.

Both of these activities are expected also for future seminars of these prorammes.

Pilleriin Peets presenting at Technart 2017

On May 02, 2017, the first day of the Technart 2017 conference (Bilbao, Spain) doctoral student Pilleriin Peets from UT Analytical Chemistry group made a presentation Identification and classification of textile fibres using ATR‐FT‐IR spectroscopy with chemometric methods (Photo on the left).

The presentation outlines the recent results by Pilleriin in creating the method for quick, easy and non-destructive classification and semi-quantitative analysis of textiles using ATR-FT-IR spectroscopy combined with chemometric data analysis methods.

She investigated altogether 89 individual textile materials – Wool, Silk, Cotton, Linen, Cellulose acetate, Lyocell/Tenzel, Viscose, Polyester fibre, Polyamide fibre, Polyacrylic fibre, Elastane and their different combinations – and created a discrimination/classification model using principal component analysis (Image on the right).

As a side-product of this work, a collection of ATR-FT-IR spectra of textile materials containing one or two different fibres was composed and is deposited in the Supplementary data of the paper that she recently published: P. Peets et al. Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy 2017, 173, 175–181.

This collection of ATR-FT-IR spectra helps to identify different kind of single- and two-component mixed textiles.

Technart conference series is a premier scientific forum dedicated to applying analytical techniques in the field of art and cultural heritage.

UT_Measurement_Uncertainty_MOOC_Participants_2017On Monday, March 27, 2017 the web course “Estimation of Measurement Uncertainty in Chemical Analysis” was launched the third time as a MOOC (Massive Online Open Course).

Currently 336 participants from 62 countries are registered. The somewhat decreased popularity of the course is most probably due to the fact that starting from this year certificate of completion on paper is not free of charge (digital certificate is still free). Given this change, we are actually surprised that we still have so many participants! Image on the left shows the countries where the participants come from. As in the previous years, the majority of participants are from analytical laboratories, once again demonstrating the continuing need for training in measurement uncertainty estimation in analytical chemistry.

The full course material is accessible from the web page https://sisu.ut.ee/measurement/uncertainty. Some developments and improvements have been made to the course material, in particular, better description of course organisatsion a self-test on sophisticated uncertainty estimation taking numerically into account the limited selectivity of the technique (potentiometry with ion-selective electrode). 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 take six graded tests and get higher than 50% score. These tests are available to registered participants via the Moodle e-learning platform.

 

Measurement_Uncertainty_Value_Error_EtcThe online course Estimation of measurement uncertainty in chemical analysis will start its 4th edition on Monday, Mar 27, 2017. 300 participants have already been registered from 58 countries. Registration is still open and all people interested to learn this important topic are welcome to participate!

The registration link is available from the course website: https://sisu.ut.ee/measurement/uncertainty

 

LCMS Method Validation online course offered by UTOn Feb 16, 2017 the MOOC LC-MS Method Validation finished successfully.
Altogether 303 people were registered from 61 countries. 224 participants actually started the course (i.e. tried at least one graded test at least once) and out of them 168 successfully completed the course. The overall completion rate was 55%. The completion rate of participants who started the studies was 75%. Both completion rates are all time highest that our group has seen in our MOOCs!

The questions from the participants were often very interesting, often addressed things that are really important to analysts in their everyday work and in several cases led to improvements in the course. 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 want to thank all participants for helping to make this course a success!

We plan to repeat this course again in Autumn 2017.

 

EACH_Winter_School_2017_Group_Photo_on_Lake_ErkenFriday 27.01.2017 was the last day of the EACH Winter School 2017. It appears to have been a memorable experience for all participants, especially those from southern countries. For example, quite some people had never walked on ice in their life, not to speak about jumping into water from sauna or under ice fishing! (See the previous post).

We were able to experience the best of Sweden – Swedish food, nature and hospitality, which was spiced up and complemented with exotic dishes and participants’ enthusiasm.

Wednesday Jan 25, 2017: a major entertainment on that day of the Winter School was a short fishing trip to the nearby lake Erken. The lake is covered with ice and the participants had to use an ice drill for making the holes for fishing. It was a lot of fun and an exotic entertainment for those from southern countries!
