<p>Anitaw, I am not the parent of an engineering student, but I think my comment came pretty close to jmmom's in intent. I understand that engineers have to sometimes make fast decisions -- but so do lawyers & political leaders who often come from a very different type of education in the humanities. I am not sure that the best way to build the ability to make such fast decisions is through intense pressure during undergraduate exams -- I think it would be much better to work to ensure a thorough understanding of the material, building up the skill level and familiarity with situations that left more time for thought and reflection. Let the hurried judgments be made by those who have already acquired the foundational mastery of the subject matter so that they don't have to combine their quick reaction time with wrestling to remember basic facts and formulae that a few years down the line will have become second nature to them. </p>
<p>Here's why I dropped chemistry and abandoned a science major: I got a B. </p>
<p>What disturbed me is that I spent the whole semester feeling almost clueless about what was going on, went into a final exam with hardly any sleep, was confronted with questions that didn't seem to make sense, and somehow a glimmering of an answer just came to me during the exam... so I went with my gut and wrote it down and I turned out to be o.k. with it. In a class with 400 students I had done very well.</p>
<p>But I didn't <em>understand</em> what I had done. I didn't think I could do it again. And I felt if I continued.... I would just end up with future B's in settings where I didn't have a clue as to what or why I was doing whatever I did to pull it off. And I wasn't comfortable with that ... because I knew that I did not have B-level mastery -- or even D-level mastery -- of the subject. </p>
<p>I'm good under pressure, so it is not at all unusual for me to find that the answer just "comes" to me like it did on that exam... but that's not too reliable. It's more like a skater who can occasionally nail a double axel but lacks the technique to do it consistently - that skater needs a lot more practice before competition. </p>
<p>I don't have a problem with the idea that a good exam will have some questions that may take the student a step further and require some real thought -- but I think edad's comment about the range of questions and evaluative purpose on an exam make a lot more sense, if the real goal is educating the student. I'm not sure whether, in some schools, the primary goal is simply to weed out the weakest third of the class rather than to educate everyone. </p>
<p>I think the downside of such an approach is that it discourages a lot of students from entering the sciences. I've noticed that one of the qualities that women's colleges like Smith and Barnard are quite proud of is their ability to encourage women to pursue sciences and excel in them... and I'm wondering how much of that simply stems from a more supportive, and ultimately more effective, approach to teaching the basics.</p>
