Reflection

I was ill in the morning. I was ill already for a week and hence was more absent from all team discussions.

Teaching 9:00 First login

There were 5 visitors. Me and the team were able to help all of them. I’ve helped 1 learner and it was a good experience: she was a complete beginner and at the end of my, around 15 minutes, help, she was super ready.

Teaching 10:00 Load modules and run

There were 6 learners. Most time was spent with the 1 learner that did not attend the login session.

When ill, my talking is slower. A good thing. However, due to the constant pain, I do not enjoy my teaching sessions as usual.

I did meet all students properly. At 10:47 2 (out of 6) were done: I sent them on an earlier break.

Teaching 14:00 RStudio

Me and a colleague split up the learners: the colleague offered to help, as it was unsure how well I was (as I was less response in chat, due to -indeed- illness). I think it is nice to get unexpected help and I think it is a good idea that she had a 1-on-1 with ‘her’ COSMOS users. So, we split up, after announcing this in the main room.

I was very happy to see my learners again. We were with 3, 1 that used Sigma, and 2 that used Dardel. I started with the Sigma user, as (1) she has no documentation, and (2) Dardel has Open OnDemand, which is easier. I did so after discussing this with the whole group.

When the Sigma user was in the system (for the first time), I told her to try a bit for herself, so I could talk to the Dardel users. We agreed.

I disturbed the Dardel users. They were already done. I told them that in 5 minutes I will give a bit more in-depth demo about RStudio, after helping the Sigma user (which I estimated to cost that long). The Dardel users agreed.

The Sigma user was in quickly, so we started talking as a class again. I did my demo on RStudio, until it was time again to back to the main room.

I remember from earlier reflections that I should not be too informal, and I think I succeeded reasonably (but not perfectly) well: it felt too nice to have them back :-)

15:00 Summary and Evaluation

I went through the summary. What was missing was a list of other course.

  • [x] Add link to SCoRe list of courses

The evaluation was clean: I told them why I put them in breakout rooms. One out of six learners came back to ask his questions, which I discussed in a breakout room.

Predictions

My sessions went very well:

  • In the ‘Load modules and run’ session, I have seen all run the R interpreter
  • In the RStudio session, I have seen all run RStudio

Evaluation results

Average confidences per question

Average confidences per question for my sessions

The only useful item is ‘Do you have any additional comments?’:

  • I liked the online material about how to prepare and get everything set up, which has been my main issue so far. Unfortunately I could not initially run R via the terminal/ssh, so I couldn’t do the practicals on batch, but I am sure I can figure it out myself.

Too bad. Nothing to be done about that I guess …?

  • no

Sure :-)

  • no

Sure :-)

  • awesome material and good that you record but could you record during the lectures all of you so we get the exact thing that is taught? I’m also not fond of having to have the camera on which i felt there was pressure to do so i watched most after the course instead

This is an interesting comment: on the one hand this person mentions to not like the camera. On the other hand, the learning outcomes for my early sessions for that person are highest:

Learning outcome Camera Confidence
I can find the module to be able to run R Yes I can absolutely do this!
I can load the module to be able to run R Yes I can absolutely do this!
I can run the R interpreter Yes I can absolutely do this!
I can run the R command to get the list of installed R packages Yes I can absolutely do this!
I can run an R script from the command-line Yes I have good confidence I can do this
I can find out if an R package is already installed No I have good confidence I can do this
I can load the pre-installed R packages No I have good confidence I can do this
I can install an R package from CRAN No I have good confidence I can do this
I can submit a job to the scheduler to run an R script with regular code No I have some confidence I can do this
I can submit a job to the scheduler to run an R script that uses parallel code No I have some confidence I can do this
I can start an interactive session No I have low confidence I can do this

So in this case, higher learning outcomes were achieved in the sessions with a camera, including by the person that did not like using a camera.

About having videos to the material, I find that live recordings have ‘No performance advantage was found for viewing recordings despite students’ positive perception of their utility.’ [Lesser, Melissa, and Lora Packel. “Educational Lessons from a Pandemic: Lecture Recording and Learning Outcomes.” Internet Journal of Allied Health Sciences and Practice 22.2 (2024): 9., Link to paper]. However, that paper does find positive effects for learners that, unlike here, use it after attending a session.

The RStudio sessions

I’ve compared the simultaneous sessions of this course’s iteration with the previous course iteration where I was the only teacher:

learning_outcome teacher average_confidence
I can start an interactive session with multiple cores RB+RP 1.4
I can verify I am on the login node yes/no RB+RP 1.5
I can start RStudio RB+RP 2.7
I can verify I am on the login node yes/no RB 3.1
I can start an interactive session with multiple cores RB 3.1
I can start RStudio RB 3.4

It seems same enough. The biggest differences are from things that one does not need when using Open OnDemand.

  • [ ] Remove learning outcome ‘I can start an interactive session with multiple cores’
  • [ ] Remove learning outcome ‘I can verify I am on the login node yes/no’

Taking a look at the confidences per question for RStudio:

Confidences per question for RStudio

Could it be that we both scored ‘I can absolutely do this!’ and that deviations from this are explained by people not following the session?

Here is when learners rated the RStudio session:

Starting time Confidence for ‘I can start RStudio’
10/6/2025 14:45 I can absolutely do this!
10/6/2025 14:54 I have no confidence I can do this
10/6/2025 14:53 I can absolutely do this!
10/6/2025 14:53 I can absolutely do this!
10/6/2025 14:53 I can absolutely do this!
10/17/2025 13:09 I have no confidence I can do this

I think the last person may not have followed this session at all. It would make sense: I’ve had 2 and Rebecca had -according to my notes- 2 or 3. I think it is likely enough that 4x ‘I can absolutely do this!’ comes from the 4 learners attending our session and the 1x ‘I have no confidence I can do this’ comes from the COSMOS SENS person. I conclude that me and Rebecca did a perfect job!

This brings us to another problem: the learner that was absent filled in a ‘I have no confidence I can do this’ over skipping the question. As far as I remember, it was impossible to skip questions.

  • [ ] Suggest to make confidences optional (i.e. one can get away to not fill in a confidence) to remove this skew
