Editor's Notes

  • #2 A skill relevant to ALL liberally educated adults.
  • #3 Statistics courses play important role in item 1. Other departments have crucial role in items 2-4. Steen 2004
  • #5 What we’re after: conditioned responses! That’s right! 53% of fatalities take place over 43% of the days…days likely involving more than 50% of the driving!
  • #6 Body: “more than doubles the risk of life-threatening cardiovascular complications” But what is the original (or ultimate) level of risk? Never mentioned. (NYT article reveals 1.47% vs. .67%. But time period unspecified. And buried in last paragraph and after the jump)
  • #8 How do we attract involvement from other fields? Meet them where they are at.
  • #9 We ALL want students to argue effectively and persuasively Not saying all QR is rhetoric—but good argument demands QR!
  • #11 Examples of questions periphery answers
  • #12 Importance of periphery in potential QR instruction at Carleton
  • #13 Some evidence of student awareness, but much work to be done
  • #14 Richard Light, Making the Most of College, Characteristic of Faculty who make a difference Weasel words rip my flesh—slate Introductions to lit reviews—not inherently QR assignments
  • #15 Other examples
  • #16 More effective introductions.
  • #17 And this has been limited by enrollment caps
