<p>Yeah, but I can totally show you the burn marks from where my charger burst into flames. Completely scared the fark out of me.</p>
<p>See, that's the problem with the academic mentality, dude. We can draw up as many grandiose and ornate plans as we'd like, and say that this is the way it really <em>should</em> be, but who's gonna implement 'em? It's not that I disagree with you, I just don't see how, in the reality we live in, your ideas can be put into practice. I see the difficulty of engineering education as being, in part, a failsafe mechanism so that people who <em>won't</em> be able to hack it as engineers can get out while they still have time to fully pursue other career options. Because if you flunk the PE repeatedly, then by that time, you've already invested eight years in engineering! It's kinda too late! (At this point, if I had the time or the energy, I'd go through and address all the titchy little points that sakky's inevitably going to bring up, like how failing a class or two would hurt someone's chances of getting into another field... I would, for example, counter that with the idea that a failing grade is something you can kinda see coming down the avenue, and that students have a responsibility to take advantage of their ability to drop classes before it's too late... but how's about we stick to the big picture here?)</p>
<p>But even more importantly, at the end of the day, like wrprice said (thanks, dude, this is the more immediately relevant point I was looking for), engineering's about attention to detail. In my case, <em>inattention</em> to detail can kill people, and that blows, to put it mildly. The fact that engineering's pretty darned objective allows professors to grade harshly only reflects and promotes good habits in a practicing engineer: attention to detail, and a high level of accuracy. I made an adding error on an exam in a design course and the prof took off 12 points. I squawked, of course, as soon as I got it back, protesting amid my colleagues that 12 points was kind of harsh, and the prof countered, "You should be able to add two one-digit numbers by now, Amy."</p>
<p>Embarrassing... sure... but boy-howdy, did my arithmetic accuracy skyrocket. One simple act of oppressively harsh grading did the trick. </p>
<p>If you watch a really masterful engineer work... and I've had the fortunate pleasure of having done so on numerous occasions, with numerous masterful engineers... They are lightning fast and ridiculously accurate. Click click click click click, bang. Answer.</p>
<p>The engineering process, overall, is pretty long, and is very cumulative. If you make a dumb and careless error back at the beginning, y'know how much time you waste? I can crank out about ten pages of calcs a day, and by the end of the day, those calcs have been copied and handed to colleagues, who will take my numbers and go off and crank out ten pages of calcs of their own. If, two days later, as once unfortunately happened to me, you find that you screwed something up at the beginning, that sets <em>everybody</em> back, by a lot. </p>
<p>Accuracy's so key. Harsh grading promotes accuracy, and I speak from personal experience on that. And it's not just me, I'm not the only one who shaped up from harsh grading... When I started out grading my students' papers as a TA, their work was atrocious. I couldn't read any of their papers, their thoughts weren't presented well, and their answers were invariably waaay off. It was their first design class. I graded harshly*, and told them that I'm their client, and if I can't read it, I'm marking it wrong, because it won't do me any good. Your clients and colleagues have to be able to read your work, because engineering is a collaborative process. Their work improved EXPONENTIALLY. It was fantastic. By the end of the course, their stuff was spotless, and the ones who put in the work aced the final.</p>
<p>So, it promotes healthy engineering habits. It's the nature of the beast. If you don't like having to be accurate, don't major in engineering. If you want to major in engineering, suck it up!</p>
<p>*Say I'm mean if you want to, but then tell me how many of your TAs would go through your work, count off for a mistake at the beginning, then follow through with your incorrect numbers and not count off if your process was correct. I'd handwrite answer keys with full explanations, and at the students' requests, I held copious review sessions, the same session at multiple times during the week, to accomodate everyone's schedules. I'd write up review packets, I'd bring post-it flags so they could mark up their codes, I had a separate IM address so that they could IM me with their questions whenever I was awake, and I gave out my home and cell phone numbers and would stay up until 3 AM the night before problem sets were due... So no more of this crap about "omg aibarr must've been such an awful TA!" =P</p>
