<p>Homework often counts for 10% of the grade to combat cheating. If people are just going to buy the book answer keys and share them with each other or use the answer bank their fraternity keeps on file from previous semesters, then counting homework as 30% of the grade is pretty silly because it will tend to inflate grades and penalize those who don’t cheat. Unless, of course, you flat out give every student the answer key and say have at it, in which case at least it’s fair, though grades would still be artificially high. That isn’t as large an issue at community colleges where the student turnover rate is higher and there are no persistent institutions like fraternities that can hang onto answers like that. At the very least, the cheaters are going to have to work for it.</p>
<p>That said, I am not trying to imply that early mathematics courses couldn’t use a nice improvement in quality. The thing is, people who play the weed out card and claim the professor is simply out to fail everyone are just making excuses 99 times out of 100. The real problem is multifold and much more complicated to fix.</p>
<p>For one, students are often unprepared for the rigors of a university math course for a number of reasons ranging from poor high school preparation to poor study habits, and they often struggle at first in the university setting, which just happens to coincide with when all the “weed out” classes occur. No one ever seems to stop to consider that the reason later classes don’t seem as ridiculous and hard may just be that they have gotten wiser and developed better habits. They are just too quick to play the victim card.</p>
<p>Another part of the problem is that the newest professors with the least teaching experience often get assigned to those early classes that none of the older tenured folks want to teach. Generally, the older faculty put in their time teaching those low level courses and really would rather spend their teaching time teaching the more specialized courses associated with their interests. They often get their way.</p>
<p>The last thing is that those early, large classes are increasingly taught by part-time faculty (adjunct professors). They are generally paid very poorly and have 4 or 5 courses to teach in a semester. Even the best teachers can be quickly demotivated by being extremely overworked while extremely underpaid. In engineering departments this isn’t usually a problem because they have enough money to pay for tenure-track faculty, but in some of those early departments like chemistry and math, adjunct faculty outnumber tenure-track faculty. It’s a real problem.</p>
<p>When I was in the first year or so of my undergraduate studies, I probably would have been right there with a lot of the folks here talking about weed out classes and being mad that professors were intentionally making life hard on the students. After spending time getting to know a sizable number of professors personally and getting closer to the issue and teaching classes myself, I really can say that I believe the actual occurrence of that is quite rare. You get a few real jerks who are teaching to make people miserable, but the vast majority legitimately would like to see their students succeed. Instead, the problems are the ones listed above, and they aren’t easy to solve.</p>
<p>To solve the first one, you have to reform K-12 education, which means tackling some powerful national political forces and institutional inertia. It needs to happen, but it is not something that will come easy. The second issue is easier to fix, as you just need to convince departments to require older faculty to teach earlier classes from time to time. Of course, then the younger professors are just going to be earning their sea legs in the higher classes, so you are pretty much screwed either way there. The last one could be solved pretty simply if someone could convince US News to include the adjunct to tenure-track ratio (or else not count adjuncts in the faculty to student ratio) in their rankings and penalize schools who fall to far on the wrong side of it. Otherwise the schools have no economic incentive to rectify that.</p>
