I can only think one subject I was in that had attendance marks, and I'm not sure I approve. Why is attendance the magic thing, rather than mastery of the content?
I take particular issue with the framing in that article, that it was "a good way to help students struggling academically", at the same time as offering them the threat of failure if they don't attend 80% of classes. Sounds more likely to produce anxiety than anything else.
The use of tracking is probably just a way to try and help automate an existing manual process. Speaking as a software developer, we like doing that kind of thing, and assume it will magically make things better - but I would think it fairly unlikely it has all the safeguards in place it needs to have. But the more fundamental issue is "Is that manual process actually required?" My opinion: No. Even if the tracking is 100% effective and the data collected has 0% chance of being misused, it's still not needed.
