From the requirements - or rather desired properties.

Isn't this requirement a common fallacy in education?
First, just because you know skill A and skill B does not mean you can automatically do both A and B together. (Of course it helps!)
Assume you're learning a to play piece of music. If you learn a given sequence [A, B] and start with individually learning the parts A and B you'd still have to practice the transition.
Second, just because you know a composite skill does not mean you can do each part individually.
Again assume you've learned to play a part of a piece of music and the notes constituting this part can be decomposed as [A, B]. Then you'd not directly know how to play B on it's own because you've propably learnt to enter B transitioning from A.
Still: I think the overvall approach is interesting. Just the details might be a bit off.
- schmidtleonard 1y agoSure but don't let the perfect be the enemy of the good. "Big bucket of courses, bring your own plan" and "here's your mass produced course plan that may or may not be optimized for departmental needs rather than yours" are both pretty rough. A skill tree is a step up even if it needs a little (or a lot) of refinement.

Whole careers have been built on being one of only a few people in the world who can perform A and B together. Like that physics guy who can also write good sci-fi. There are 3 skills actually. A, B, and A u B. That intersection is often the hardest.
- queuebert 1y ago> Like that physics guy who can also write good sci-fi. Stephen Baxter? Or someone else?
- Swizec 1y agoI was thinking Andy Weir but yeah there’s probably several. A strong physics background surely helps with writing better sci-fi
- antonvs 1y agoAlastair Reynolds is who I thought of. PhD in astrophysics, worked at ESA. But there are several other scifi authors with decent physics resumes.
- sshine 1y agoJames Baxter? Jaaaaames Baaaaxter!
- chrisweekly 1y agoYeah, I've heard this referred to as "skill-stacking". If you're in the top 10-20% at two different things, you might be in the top 1% of people who can do both.
- criddell 1y agoIs your skill tree too sparse? Instead of [A, B] maybe it should be [A, A->B, B]
- yorwba 1y agoYes, the whole point of having the "Subskills cover skills" requirement is that if this requirement is not fulfilled, the skill tree is missing a subskill and needs to be expanded. The authors state that in the process of building a skill tree for their database course, they noticed that SQL triggers were introduced without discussing SQL update queries first. Probably because they hadn't tried to explicitly list all requirements at such a fine-grained level before.
