Scientific Teaching
Goals: • to introduce ST/AL (scope, need for it, evidence of benefits)• to practice some ST/AL methods.• to critically examine some of its claims
& Active Learning
objectives: after this session, you should be able to:- explain the core concepts behind ST/AL;- find and critically read some primary research papers on
evidence for ST/AL effects- find more ST/AL resources and tools - devise ways to transition a course unit from a passive
(lecture-only) to a more active mode.- anticipate the challenges that may arise when doing this.

What happened (or didn’t happen) in lecture 1?
Could this have been taught more effectively ?
How? (Think-Pair-Share)
What should I do next (in lecture 2) ?(Think about this, – Pair to discuss - Share your
conclusions)
Why “scientific” teaching?
EmpiricalInquiry
Creativity
Rigorous
Data
Interest Real content
bringing the spirit and the standards of research from our lab/field to the classroom
developed by science researchers (but has older, broader philosophical roots)
for those, trained as researchers, who also teach science
Spirit ? Standards/methods?
WonderCuriosity
StatisticsControlled
A major, broad-based effort.....
Why scientific teaching ? - broad science literacy
• high overall loss rate from STEM majors (~ 50%) - shift to other majors - drop out of college
- scientifically skilled workforce
• loss rate higher &/or advancement lower for - poorer students- some (cultural, ethnic) minorities- women

Effects of lecturer performance:video lecture on genetics of calico cats
fluent lecturer dysfluent lecturer
“In the fluent video, the instructor stood upright, maintained eye contact, and spoke fluidly without notes. In the disfluent video, the instructor slumped, looked away, and spoke haltingly with notes.”
Carpenter et al.,, Psychonomic Bulletin & Review May 2013
Effects of lecturer performance
“The fluent speaker was rated as significantly more organized,knowledgeable, prepared, and effective than thedisfluent speaker, ts > 8.77, ps < .001, ds > 2.70 .....”
“Participants who viewed the fluent speaker also indicated that they learned the information better (M = 3.48, SD = 1.03), as compared with those who viewed the disfluent speaker (M = 1.76, SD = 0.89)......”
Carpenter et al.,, Psychonomic Bulletin & Review May 2013
Effects of lecturer performance“After watching the video, participants ... were asked to predict how much of the content they would later be able to recall.....” and were tested, after a 10 minute interval, on how much they actually recalled. Results:
