A Telegram chat room for the course has been opened. We recommend that you use the channel either through a web browser or the Telegram desktop application.
The discussion channel is based on peer support. The teachers of the course (Saska Dönges and Veli Mäkinen) are participating the discussion on voluntary basis if time permits.
Start the course by solving the TMC assignments.
After completing the TMC assignments, you can proceed with the final project.
Select one of the project options listed below, follow the instructions, and return your solutions to Moodle in Jupyter notebook format . Then conduct peer-review: You should evaluate and give feedback on your own report and two other reports.
The projects on sequence analysis and on regression analysis are integrated to the TMC system and the course material includes detailed instructions on these. For the project on fossil data analysis all the instructions are in the pdf below, and you can start from an empty Jupyter notebook to conduct the project.
The instructions on peer-review will be visible in Moodle after the submission deadline, but meanwhile here are the evaluation criteria:
1. Give a grade 0…5 on the correctness of solutions, and provide constructive comments where you find places for improvement.
0: Less than half of assignments solved satisfactorily
1: At least half of assignments solved satisfactorily
2: At least half of assignment solved pretty correctly
3: 65% of assignments solved pretty correctly
4: 80% assignments solved pretty correctly
5: All but 1 assignment solved almost perfectly
To assess the percentage of correctness, you may give fractional points from a serious (but failed) attempt, 1 point from essentially correct answer, and divide total points by maximum points.
2. Give a grade 0…5 on the clarity of writing and code, and provide constructive comments where you find places for improvement.
0: Writing and code are not at sufficient level in the solved assignments
1: Writing and code are mostly at sufficient level in the solved assignments
2: Writing and code are mostly at satisfactory level in the solved assignments
3: Writing and code are mostly at good level in the solved assignments
4: Writing and code are mostly at very good level in the solved assignments
5: Writing and code are mostly at excellent level in the solved assignments
In each category, in addition to textual feedback, give also a grade in the range 0, 1, …, 5.
The final grade for the project work will be the weighted average over the two categories, where category 1 has weight 2, and the second has weight 1. You must get at least grade 1 for the project work.
If you wish to have the credits entered in the University of Helsinki’s student records, you must first register for the course at the Open University. The ECTS-credits are available for those who have Finnish identity number and an online bankig ID, and for International students at the University of Helsinki.
All studies you complete are entered into the University of Helsinki Oodi system within four to six weeks of the date of completion. Failed grades are also entered into Oodi.
Once the results have been recorded in WebOodi, you will receive a notification in your helsinki.fi email. You can then request a transcript of studies , which serves as an official certificate of completed studies.
If you are on the path to finish the required TMC assignments, please do the following steps in order to continue with the project and the exam:
1. Register for the course through the Open University: https://www.avoin.helsinki.fi/palvelut/esittely.aspx?o=129239201
2. Wait for 24 hours and activate your University of Helsinki user ID . You will receive instructions on the activation process the following day.
3. Sign in on the course page, where you will find the enrolment key for the Moodle space: https://courses.helsinki.fi/fi/aycsm90004en/129239201
4. Sign into the Moodle space with your University of Helsinki user ID and the enrolment key.
5. Add your Univ. Helsinki *student number* to your TMC account (Click your account on top -> Settings-> Organizational identifier)! (We'll need this for grading, to match records between TMC and Moodle.)
- Registration for the course through the Open University is possible until May 3, 2020.
- Credits for the course are only available to those students who have successfully registered for the course through the Open University and have completed the course according to the instructions.
First 6 weeks (aka parts) of the course consist of automatically assessed exercises (using TMC system). There is a "soft" deadline in the end of each part until which one can gather full points from that part; late submissions are counted as 75% of their value. After completing these parts (at latest by the hard deadline in the end of the course), one should have gathered at least 50% of maximum points in order to continue with the final evaluation.
Final evaluation of the course consists of a multiple choice exam (in Moodle) and a peer-reviewed project work (in Moodle). The exam tests directly the knowledge gained while the project tests the ability to apply the learned skills in some selected field of science.
To pass the course (with grade 1), one need to pass TMC assignments (50%), exam (50%) and project (50%) and take part in peer-review of the project. Grading (for grades 2-5) is based on an overall assessment of TMC assignments, exam, and project. Each component is assessed independently and weighted average determines the final grade.
For the TMC assignments the grading scale is 50%=1,58%=2,66%=3,74%=4, and 82%=5.
For the exam the grading scale is 120 points=1,140 points=2, 160 points=3,180 points=4, and 200 points=5, where 240 points is the maximum.
The project work consists of similar tasks as in the weekly TMC assignments, but this time building a coherent story around a selected field of science. Currently the project topics offered are on fossil data analysis, on medical data analysis and on sequence analysis, of which you can select your favorite. For the latter two project options we provide a template containing placeholders for discussion around the code, and the outcomes can also be tested in the TMC system. However, for final submission, instead of TMC, the project solutions are to be collected in Jupyter Notebook format and submitted to Moodle for peer-review. From this peer-review one can then get feedback from the clarity of solutions and the style of code, complementing the automatic TMC assessments. In addition to peer-review, the project work is also self-assessed. The grade of the project is determined by an overall assessment of the project and the peer-review work.
Thanks for the feedback! Altogether 44 answers makes a good statistics (see below).
The most urgent development item is a better / more structured forum for interaction between students and teachers. We tried moving the local workshops to zoom, but Q/A sessions like that didn't really fly, so we just continued with Telegram. However, whatever the forum is, there is always the resource limitation: For MOOCs like this, we really cannot put much more teaching resources than 2 hours for teaching assistant / week + teacher handling mainly just administration.
Note also that this course is somewhat experimental (product of Digiloikka-incentive) in that we aim for maximum possible automation, even in grading, without sacrificing learning objectives and equal treatment. E.g. regression and sequence analysis projects are integrated to TMC so that peer-review works as well as it can (very little discrepancy in given grades). It would be great to offer more open-ended projects, but then self- and peer-reviews are not much of help for grading. Currently we can only afford one such project (fossil data analysis). Without all these automated elements, we could never have this course in the curriculum.
