Observations during lessons¶
During the lessons I observed the timings of me and BC:
| Time | Who | Description |
|---|---|---|
| 9:04 | R | Start monologue Introduction |
| 9:11 | R | Start monologue FileZilla |
| 9:18 | R | Open BO rooms |
| 9:25 | R | Done with first visit to BO room |
| 9:50 | . | Break |
| 10:05 | R | Start monologue SSH |
| 10:08 | B | Start monologue scp |
| 10:14 | B | Start questions |
| 10:17 | B | Open BO rooms |
| 11:00 | . | Break |
| 11:15 | B+R | Start monologues |
| 11:25 | B+R | Open BO rooms |
| 11:45 | B | Start monologue wrapup |
| 11:50 | R | Start evaluation |
The goal was to determine the percentage of exercises:
| Time | Monologue | Dialogue | Exercise | Percentage exercise |
|---|---|---|---|---|
| 9:00-9:50 | 18 mins | 0 mins | 32 mins | 64 percent |
| 10:05-11:00 | 9 mins | 3 mins | 33 mins | 60 percent |
| 11:15-12:00 | 25 mins | 0 mins | 20 mins | 44 percent |
| 9:00-12:00 | 52 mins | 3 mins | 85 mins | 61 percent |
So 61% of the time it was time for exercises.
I also tracked BC moving through different BO rooms in the scp
session (he was never in the main room), just to get a baseline
of speed:
| Time | BO room with BC | Duration |
|---|---|---|
| 10:17 | 1 (start) | 6 mins |
| 10:23 | 2 | 7 mins |
| 10:31 | 1 | 7 mins |
| 10:38 | 2 | 6 mins |
| 10:44 | 1 | 16 mins |
| 11:00 | Break | . |
Reflection¶
I am reasonably happy with how this day went: the atmosphere within the little group (me, BC and 4 learners) was very good and it seems people had fun.
What I am conflicted about is that I abandoned the teaching cycle (i.e. no Prior and no Feedback), even though I prepared for it. The reasons were (1) I want to use a short amount of time, to assure BC has proper time to teach, (2) I felt it was not worth it for such a small group.
Three out of four learners had an HPC cluster that uses SSH keys, and
hence need a .ppk file for using FileZilla. We pick FileZilla because
it is intuitive, but for them it is the opposite. Maybe we should do scp
first, as this is easy for everyone. Hence, if most people use
Alvis and Dardel, reverse the schedule to this:
| Time | Teacher | Topic |
|---|---|---|
| 9:00 | R | Intro |
| 9:05 | R | Login with terminal [moved earlier] |
| . | B | File transfer using scp [moved earlier] |
| 9:50 | . | Break |
| 10:05 | R | File transfer using FileZilla [moved later] |
| 11:00 | . | Break |
- [ ] Suggest to use this schedule if Alvis + Dardel people are in the majority
One learner slowed us down: he had not logged in to his HPC cluster.
During the teaching, I found out that the rsync answers were incomplete,
and created an issue to fix it.
While preparing, I did find out LUMI has not documented FileZilla usage. I contacted CSC support. I've already gotten the reply, but not on time for today.
I think me and BC worked well as a teach. For sure, I enjoyed how well we, for example, discuss to have an earlier break. Sometimes BC got what he wanted and sometimes I.
In conclusion: I am still unsure how well the teaching went, regardless of the very happy learners.
Evaluation results¶
| Question | Mean | Comment |
|---|---|---|
| I am comfortable using the documentation of my HPC center | 4.3 | indeed, there was some bad documentation for the HPC clusters used |
| I can compress and archive files before transferring | 4.3 | unsure, I have not seen learners struggle with this |
| I can log in to my HPC cluster using SSH | 5 | indeed, this is a prerequisite |
| I can transfer data using FileZilla | 4 | indeed, this is the hardest and we skipped |
| I can transfer data using rsync | 4.7 | unsure, only 2 out of 4 chose to do this |
| I can transfer data using scp | 5 | indeed, worked like a charm |
| I can transfer data using sftp | 5 | unsure, did anyone do this...? |
| I can transfer files between clusters | 4 | indeed, no practice/exercise |
Say something positive about Richèl¶
- Very happy
- Good positive energy!
- Richèl explained the concepts in a clear and engaging way, and I especially appreciated the short videos he used to show the implementation, thank you for your time and effort
Great!
Say something about Richèl he can improve¶
- (perhaps he's got a bit too much of that energy, it gets somewhat intense at times)
- No suggestions, I found the workshop well structured and clear
Great!
Conclusion¶
I would grade my own teaching as 8/10, because:
- We were able to establish a productive, fun and relaxed learning atmosphere
- I did abandon parts of the literature
