[A posting on the NIU Faculty newsgroup] RE: FAHRENHEIT 451 - SOME MORE DATA Dave Rusin (rusin@vesuvius.math.niu.edu) 11 Jul 1996 17:24:44 GMT In response to recent discussions on TomPaine, I administered the following in the last 5 minutes of today's class (a review for a test on Monday). Response tallies and class demographics follow, along with a few comments. (I don't think it's worthwhile trying to infer too much from these little tests, although they can be fun.) I have shrunk the formatting for brevity. ====================================================================== POP QUIZ Each question answered correctly gets you one point EXTRA CREDIT on Monday's test. (This is in reality an informal data-collection project assessing the nature of our general education and science education program.) 1. Who is the current Vice President of the United States? 2. What is the capital city of Canada? 3. In what year did World War II end? 4. At what temperature does water boil? 5. What is the most common gas in the Earth's atmosphere? 6. An astronaut releases a rock from shoulder height while standing on the moon. Will the rock (a) float away (b) remain stationary (c) fall but more slowly than on Earth (d) fall as if in a vacuum on Earth Thank you for your time. dave ====================================================================== Responses (most correct answers listed first). Note that N=16. 1. (Al) Gore -- 13 Gorr -- 1 Dole -- 1 blank -- 1 (This one from a foreign national) 2. Ottawa -- 6 Quebec -- 4 Montreal -- 2 Vancouver-- 2 Alberta -- 1 blank -- 1 3. 1945 -- 11 1946 -- 1 1926 -- 1 blank-- 3 4. "212F or 100C" -- 2 100C -- 7 (one added, "...at standard temperature and pressure") 212F -- 3 99.9C -- 1 "220F, 100C" -- 1 100F -- 1 blank -- 1 5. Nitrogen -- 5 Oxygen -- 5 CO2 -- 3 Carbon -- 1 "Hydrogen, Oxygen -> Nitrogen" -- 1 [I don't understand that] blank -- 1 6. (c) -- 10 (a) -- 3 (b) -- 2 (d) -- 1 Those taking the test are mostly senior or incoming graduate students in mathematics. It is perhaps relevant that many in the class intend to teach at the secondary level. The class consists of one foreign female student, one black female, one "adult" female, and 13 "typical" young white English-speaking NIU students (8 female, 5 male). Comments on the questions: 1. Suggested by a TomPaine comment 2. The wife of a former Canadian ambassador to the US was heard to complain that Americans' eyes tend to glaze over when talk turns to Canada. "I don't know," she commented, "maybe we should invade North Dakota or something." [paraphrase] 3. Suggested by a TomPaine comment. I have heard of an incident in which some local high school students were asked to put into chronological order several US conflicts. Not only did someone place WWII before the Civil War, evidently one student put WWII before WWI. 4. In accord with a TomPaine discussion I will have no problem accepting 99.9C. I find it comforting that the metric scale was preferred and used correctly. I also noted that all except the foreign national (who might not even think about degres Fahrenheit) thought to mention the units used. 5. I also mentioned verbally the opportunity to name the third-most-common gas; no one accepted the offer. 6. Prompted by the "heavy boots" episode -- see http://clunix.msu.edu/~vanhoose/astro/0086.html [Now at http://lalaland.cl.msu.edu/~vanhoose/astro/0086.html --djr 1998/08/26] (Not only did the class in that story choose (a) more commonly, but those who did had to confront the fact that the astronauts themselves did _not_ float away. Typical explanation: "heavy boots".) The moon's gravity at the surface is about 1/6 as strong as Earth's at its surface. Comments on the quiz: I was not displeased by the students' responses. Actually I have had this experience before: that although the NIU freshman are disappointingly, um, undereducated, our graduating students and graduate students have a reasonable grasp of The Things Everyone Is Supposed To Know. This shows that either we can educate well, or the weak students go away, or both. (I am not quite as confident about our students' preparation _within_ their discipline, for which the standards are much higher.) By the way, I think my soon-to-be-high-school freshman daughter would have done well on the test; her brother two years younger would have some trouble. That should pinpoint what I consider to be the level of these questions. To be consistent with observations about freshmen, we must conclude children learn for 8 years, unlearn for 4, then learn back for 4 more. Incidentally, my son assures me the third-place standing of argon was in his science text (6th grade). dave
