Teaching with Clickers for Deep Learning

  1. 1. Teaching with Clickers for Deep Learning Derek Bruff, PhD – Center for Teaching – Vanderbilt University
  2. 2. Your sister calls to say she’s having twins. Which of the following is more likely? (Assume she’s not having identical twins.) 0% A. Twin boys 0% B. Twin girls 0% C. One boy and one girl 0% D. All are equally likely
  3. 3. Instructor Poses Question (<1 Min) Students Answer Independently (1-3 Min) Peer Instruction via Clickers Instructor Views Results (<1 Min) If Most Answer Correctly, Briefly Discuss Question (1-3 Min) If Most Answer Incorrectly, Backtrack (5+ Min) If Students Are Split, Have Students Discuss in Pairs and Revote (1-5 Min) Instructor Leads Classwide Discussion (2-15 Min)
  4. 4. Agile Teaching
  5. 5. Good Questions, Deep Learning
  6. 6. Traxoline is a new form of zionter. It is montillated in Ceristanna. The Ceristannians gristerlate large amounts of fevon and then bracter it to quasel traxoline. Traxoline may well be one of our most lukized snezlaus in the future because of our zionter lescelidge. Based on this information, how is traxoline quaselled? 0% 0% 0% 0% A. B. C. D. Via gristerlation Via bracteration Via lukization Via montillation
  7. 7. Factual Recall Question When you hear the term “water boarding,” what comes to mind? 1. Olympic Event 2. Fraternity Initiation 3. Interrogation Technique 4. Surfing 5. Torture John Jameson, History, Kent State University
  8. 8. PLNs in Action
  9. 9. CONCEPTUAL UNDERSTANDING
  10. 10. Concept Questions Your sister calls to say she’s having twins. Which of the following is more likely? (Assume she’s not having identical twins.) A. Twin boys B. Twin girls C. One girl and one boy D. All are equally likely. “IMG_9936e2,” Abby Bischoff, Flickr (CC)
  11. 11. Concept Questions Adam List, Chemistry, Vanderbilt University
  12. 12. Concept Questions Suppose that (1) earlobe attachment is dictated by a single gene, (2) unattached earlobes dominate, and (3) attached earlobes are recessive. From this information, you can conclude: A. Attached earlobes are seen less frequently than unattached earlobes in a population. B. Attached earlobes are seen more frequently than unattached earlobes in a population. C. Either phenotype could be seen more frequently in a population: you need more information. Jennifer Knight, Biology, Univ. Colorado-Boulder
  13. 13. Times for Telling Schwartz & Bransford (1998)
  14. 14. Representation Questions Which solution best represents HF disassociation in solution? (What does the equilibrium picture look like?) HF(aq) H+(aq) + F-(aq) K = 6.8 10-4 A B Barbara Reisner, Chemistry, James Madison University C
  15. 15. APPLICATION & ANALYSIS
  16. 16. Application Questions Consider the view of the northeastern horizon shown at a certain date and time. Which of the following best describes the positions of these constellations 24 hours later? 1. 2. 3. 4. 5. Slightly lower in the sky, closer to the NE horizon. Exactly the same place Slightly higher in the sky, farther up from the NE horizon Somewhere just above the SW horizon Not visible at all above the horizon Patrick Len, Astronomy, Cuesta College
  17. 17. Application Questions Consider two mice from the same inbred strain. These mice have identical MHC II alleles. For MHC I: • Mouse X has two alleles each of B, F and G. • Mouse Z has a mutation in one of its MHC I genes, and has two B and F alleles and one G and one H. If you transplant skin from one mouse to the other: A. X can accept a transplant from Z and Z can accept from X B. X can accept from Z, but Z will reject tissue from X C. Z can accept from X, but X will reject tissue from Z D. Neither mouse can accept a transplant from the other mouse Molecular, Cellular, & Dev. Biology, CU-Boulder
