2. Discipline vs. Career
2
Dunning-Kreuger effect:
• Expertise in a discipline probably makes us
underestimate our knowledge/skill.
• A lack of expertise in teaching probably makes us
overestimate our knowledge/skill.
Teaching is a fundamentally social activity,
regardless of topic or academic discipline.
Should a surgeon know the medical science?
Should a teacher know the science of teaching?
We should all be social scientists!
3. Scholarly Teaching
3
Goal 1:
Apply the rigor and scholarship of our
academic disciplines to the discipline of
teaching.
Goal 2:
Choose teaching methods that are strongly
informed by the best empirical evidence
available.

7. How Do People Like to Learn

Do we ever enjoy learning?
Possible candidates:
8. Common Elements?

Feedback is (nearly) instantaneous
Failure is expected (desired?)
The cost of failure is very low
Mastery requires iterative learning
Contrast this with a typical feedback loop in the
classroom…
9. COMBINED IMPACT
9
Deslauriers, et al. (2011):
Novice teachers with evidence-based teaching
techniques more than doubles student learning,
compared to an experienced and highly-rated
traditional instructor. Effect size of 2.5!
“[…] other science and engineering classroom
studies report effect sizes less than 1.0. An effect
size of 2, obtained with trained personal tutors, is
claimed to be the largest observed for any
educational intervention.”

I love talking and working with faculty,
don’t hesitate to get in touch.
Jeff’s results: Depending on the class 60-80% of my students do their WarmUps, self-reporting that they spend ~40 minutes reading/responding (very consistent average)
Average = 37%
Total participants 232
Faculty 175
Administrators
Higher Ed IT 32
Students 25
Is this bad? I don’t know! But given what we know about the relative value of lecture it certainly worries me. Is how you spend your class time grounded in evidence?
Quote from Deslauriers: “The standard deviation calculated for both sections was about 13%, giving an effect size for the difference between the two sections of 2.5 standard deviations. As reviewed in (4), other science and engineering classroom studies report effect sizes less than 1.0. An effect size of 2, obtained with trained personal tutors, is claimed to be the largest observed for any educational intervention (16).”
