Appendix 1: course attendance¶
The idea presented behind the course fee is that it will help registered participants to actually show up.
Course attendance is a known problem. Ideally, we want it to be 100%, i.e. that all learners that register for a course show up. In practice, for this is what it may look like in practice:
Figure 1: course attendance. See the procedure below to see how this figure is generated.
By eyeballing (and ignoring the 100% outlier, where 3 out of 3 showed up) we see that in those course we expect around 1 in 3 registered learners to actually show up. Although this figure shows the problem of a less-than-100-percent-attendance rate, it also shows a solution to this problem that is used at NAISS and UPPMAX: they estimate how many will show up.
Procedure¶
I went through all the courses I teach and checked for all courses that collect data on both the number of registrations and attendance. Then I copy-pasted the data that was easy to obtain to this document, including a link to where I copy-pasted the data from.
From this,
I created the data file attendance_rates.csv
(also, from a copy-paste, then some quick ruthless editing).
The plot was created by the script
create_attendence_plot.R.
