> If you give homework that takes multiple hours each week

I think I found the problem. Educators have such an obsession with homework and stealing more class time from their students they can't imagine different models where having the answers in front of you doesn't detract from learning.

Have you never used flash cards? My answers are on the back and yet...

Nobody learns learn how to design algorithms from flash cards.

Mastering any skill requires sustained practice: driving writing, basketball, auto repair, carpentry, banjo, gardening, combat juggling, web development, teaching, and yes, even algorithm design. The multiple hours of homework each weak is that sustained practice.

If anything is a waste of time, it's the lectures.

I don't know what you mean by stealing. In college you are generally supposed to devote twice as many hours outside of class as in class. It's probably stated in your student handbook. That is why 12 to 16 credit hours is called "full time". In a problem-solving discipline the best way to spend that study time is solving problems. As a bonus you can get personalized feedback when it is graded.

I'm going to call that stockholm syndrome. Many people throw around the idea of spend twice as much time in class as out. That's a fine idea for some, but many don't need it. Forcing a student to fill out problems to satisfy the instructor's concept of enough time spent is completely tangential to purpose of an education.

There isn't a requirement for the amount of time a MMA fighter spends in the gym. They set their own schedules and reap the results.

The idea is not "thrown around". It is called the Carnegie Unit: A course should be designed so that for each unit there should be 1 contact hour and 2 hours of outside-class work. This is the standard way courses are implemented in North American universities.

In my college (back in the day) they said an A student would spend 4 hours for every 1 hour. For a 15 credit student, that meant 60 hr work weeks every week and for a 20 credit student, 80 hours a week every week. It was brutal and exploitative imo. The one semester I took 12 credits, my quality of life, ability to retain material, and grades went up.

Let's face it, the average student won't do anything on their own till the night before the exam, which is a recipe for failure in any class that can't be memorized in an evening or two. If school was tailored towards the most elite self-motivated students, your analogy would apply. But something like half of gym members don't even go.

Why do you think professors give homework? It would be so much easier to just point students at study materials and leave the responsibility to them. But it's frustrating for everyone when students fail.

How is that a stockholm syndrome? Classroom hours are set low enough specifically because of the expectation of out-of-classroom work/study. The courses could meet for longer and expect all work to be done in class, but that is incredibly restrictive for planning schedules.
