|
| I'd like to offer what I've come to realize about the concept
| of homework. There are two main benefits to it: [1] it could
| help drill in what you learned during the lecture and [2] it
| could be the "boring" prep work that would allow teachers to
| deliver maximum value in the classroom experience.
|
| Learning simply can't be confined in the classroom. GP
| suggestion would be, in my view, detrimental for students.
|
| [1] can be done in class but I don't think it should be. A
| lot of students already lack the motivation to learn the
| material by themselves and hence need the space to make
| mistakes and wrap their heads around the concept. A good
| instructor can explain any topic (calculus, loops and
| recursion, human anatomy) well and make the demonstration
| look effortless. It doesn't mean, however, that the students
| have fully mastered the concept after watching someone do it
| really well. You only start to learn it once you've fluffed
| through all the pitfalls at least mostly on your own.
|
| [2] _can 't_ be done in class, obviously. You want your piano
| teacher to teach you rhythm and musical phrasing, hence you
| better come to class already having mastered notation and the
| keyboard and with the requisite digital dexterity to perform.
| You want your coach to focus on the technical aspects of your
| game, focus on drilling you tactics; you don't want him
| having to pace you through conditioning exercises---that
| would be a waste of his expertise. We can better discuss
| _Hamlet_ if we 've all read the material and have a basic
| idea of the plot and the characters' motivations.
|
| That said, it might make sense to simply not grade homeworks.
| After all, it's the space for students to _fail_.
| Unfortunately, if it weren 't graded, a lot of students will
| just skip it.
|
| Ultimately, it's a question of behavior, motivation, and
| incentives. I agree that the current system, even pre-AI,
| could only barely live up to ideals [1] and [2] but I don't
| have any better system in mind either, unfortunately.

|
| I fundamentally disagree - I vividly remember, many times
| during homework in maths for example, I realised that I am
| stuck and so don't understand something explained earlier,
| and I need to ask someone. For me, my parents were able to
| help. But later in Highschool, when you get to differential
| equations - they no longer can. And obviously if your
| parents are poorly educated they can't rather.
|
| Second point, there is no feedback loop this way - a
| teacher should see how difficult is his homework, how much
| time students spend on it, and why they are struggling.
| Marking a piece of paper does not do it. There was wild
| inconsistency between teachers for how much homework they
| would set and how long they thought it would take students.
|
| Lastly, the school + homework should be able to accommodate

| I feel like this is almost exactly moving all evaluation into
| the class. If "little" becomes nothing, it _is_ exactly that.
|
| I feel this was always the best strategy. In college, how
