    • Schon reflection model

4
My kindergartener
  • Rachael (age 5 years)
  • Virginia (age 3 years)
5
How do I teach my kids
… how do they learn?
  • Do we really need ACGME speak to answer these questions?
  • Don’t we teach already?
  • What do we already know but don’t realize that we know?
6
How do we teach residents?
  • Read one
  • See one
  • Do one


  • The apprenticeship model (is this the best way)
  • Can apprenticeship model measure any outcomes?
7
Rachael learning to ride a bike
  • What her learning process was NOT…
    • Read one, see one, do one
    • She cant read! (yet)
    • Watching me ride a bike wont help!
  • All learners progress through stages of learning (the Dreyfus model)
8
Paradigm Shift
The Dreyfus model of skill acquisition
  • Stages of competence
    • Novice
    • Beginner
    • Advanced beginner
    • Proficient/Competent
    • Expert (not everyone reaches this stage)
9
Status quo:
Norm referenced global evaluation
  • Global evaluation form (peer benchmarked)
    • Excellent surgeon (>75%)
    • Good surgeon (50-75%)
    • Fair surgeon (10-50%)
    • Bad surgeon (<10%)
10
The Dreyfus model for Evaluation using defined behavioral anchors
  • Stages of competence Samples of behavior
    • Novice Prep, Drape, Anesthesia
    • Beginner Capsulorhexis
    • Advanced beginner 1 handed techniques
    • Proficient-Competent 2 handed techniques
    • Expert < 15” case
11
The Dreyfus model for Evaluation using defined behavioral anchors
  • Stages of competence Samples of behavior
    • Novice Turn on laser
    • Beginner Fire few spots, know how
    • Advanced beginner Performs + supervision
    • Proficient-Competent Independent laser Rx
    • Expert Teaches others
12
The problems with “Norm referenced criteria”
13
Is Rachael “above average, average, or below average” for learning to ride a bike?
  • Does that information help at all?


  • Practice under supervision
  • Practice with training wheels
  • Remove training wheels
  • Practice, practice, practice
  • Go ride your bike…don’t forget your helmet
14
Tae Kwon Do
  • Rachael: Dad, how many years?
  • Dad: What?
  • Rachael: How many years do I have to go to class to get my black belt?
  • Dad: It doesn’t work like that, you have to progress thru Dreyfus stages, engage in Ericsson’s deliberate practice, & self reflect on progress with the Schon model
  • Rachael: Huh….Daddy…How many years?
15
How many years?
  • How many years does it take to become a PGY 1: One
  • How many years does it take to become a PGY 2: Two
  • Regardless of what color belt you actually are!!!!! (scary)
16
Old accreditation model
“Minimum numbers”
  • Procedure Class I Class I + III
  • Cataract 45 75
  • Strabismus 10 15
  • Cornea 0 5
  • Glaucoma laser 5 10
  • Glaucoma filter 5 10
  • Retina/vitreous 3 10
  • Other retinal 10 10
  • Oculoplastics 15 25
  • Globe trauma 4 6


  • Class I: Direct supervision by faculty
  • Class III: Resident first assistant
17
PGY system is also minimum numbers
  • How long until I am a second year…one year
  • How long until I am a third year…one year
  • Tae Kwon Do does NOT work like that so why should medical education?
18
Paradigm shift: Ericsson model
  • Practice, practice, more practice
  • Wet lab practice
  • Capsulorhexis (small parts of cases over and over again until comfortable)
  • Do one part of an otherwise perfect case
  • Keep practicing within Dreyfus stage until ready to proceed to next level
  • Repetition & refinement
19
It’s not about number of times!
  • How many times?
  • As many as it takes to move to the next level in the Dreyfus model
  • How many is that?
  • It might be 1, it might be 100
  • Every learner is different!
20
Schőn’s model of reflective practice
  • Reflection in action (“thinking on your feet”)
    • Surprise (response to unexpected)
    • Information seeking
    • Solve problem
  • Reflection on action (information => knowledge)
    • Review & reflect after event
    • Evaluate information
    • Apply knowledge & enhance practice
  • Goal: Knowing in action (Reach “expert” level)
21
Systematic approach to reflection in practice
  • Cognitive knowledge (read one)
    • Reflection on knowledge
  • Assist and observe (see one)
    • Reflection on action
  • Perform under direct supervision
    • Reflection in action
  • Perform without supervision (do one)
    • Knowledge in action
22
Teaching vs. learning (blatantly stolen from my friend Karl)
  • Me: I taught my five year old daughter how to use my Blackberry device
  • Karl: Wow, that’s great how’d you do that


23
Teaching ≠ Learning
(from my friend, Karl Golnik)
  • Me: Well, I gave her a lecture on the mechanics of the device, then each day I show her how I use it, & then I give her the Blackberry to practice
  • Karl: Wow, let me see her use it
  • Me: I said I taught her to use the Blackberry not that she actually learned to use it
24
Teaching ≠ Learning
25
Structure-Process-Outcome
  • Old paradigm
  • Structure-process
    • Lecture schedule
    • Titles of talks
    • Rotation schedule
    • Faculty members
    • Teaching venues
    • Apprenticeship model
  • New paradigm
  • Outcomes
    • Pre-/Post-test
    • Chart audit
    • Practice based improvement
    • Visual outcomes
    • Learner satisfaction
    • Patient satisfaction
    • Proof of learning
    • Competency model
26
Methods
  • PubMed search: “English language” (1966 to 2006): Search terms: “ophthalmic lasers”, “curriculum” & “education”
  • Titles reviewed for topicality, selected abstracts & full papers reviewed for “good practices”
  • Non-physician, paraprofessional, or pre-professional sources excluded
27
Guiding principles
  • Educational inventory of existing teaching encounters, tools & infrastructure rather than creating new tools
  • “Piggy-back” ophthalmic laser teaching on to existing teaching encounters (e.g., grand rounds, lecture, existing resident curriculum)
  • Teach & Assess simultaneously
28

How four Iowans saved One Billion lives
  • Norman Borlaug
  • Henry Wallace
  • George Washington Carver
  • Etta May Budd
46
But…no Borlaug without
Henry Wallace
  • Born: Adair County, Iowa 1888
  • Iowa State College at Ames 1910
  • High-yielding strains of corn 1913
  • Secretary of Agriculture (FDR) 1933
  • Vice President of United States 1940
  • Interred Glendale Cemetery, Des Moines
47
Henry Wallace
  • 1940, Henry Wallace: vacation in Mexico
  • Wallace noted yield of corn was much lower than his native Iowa
  • Idea - start an agriculture experimental station like Iowa
  • Rockefeller foundation funded
  • Pioneer Hi-bred International (1926)
48
The Mexico Agricultural Station
  • Borlaug selected for agricultural station in Mexico started by Henry Wallace
  • Wheat & corn hybrids in arid climates
  • Norman Borlaug single-handedly prevented worldwide famine & saved an estimated one billion lives!
  • But that’s not the cool part…
49
Who influenced Henry Wallace
  • As a child (his father was a Iowa State dairy professor), Henry Wallace used to take walks with a student at ISU named ….George Washington Carver
  • “His (Carver’s) faith in me aroused in me a natural instinct to excel and deepened my appreciation of plants in a way I can never forget.”—H. Wallace
50
George Washington Carver
  • Born a slave
  • Orphaned in infancy
  • Mother kidnapped by slavers
  • Couldn’t get an education because of the color of his skin
  • Started formal school at age 12
51
Who helped Carver?
  • First black student at Simpson College (Iowa) studying art & piano
  • Etta May Budd was his art professor
    • Helped him find gardening odd jobs
    • Encouraged him to study plants
    • Helped admit to Iowa State (1894) where her father was Professor/Chair of Horticulture
  • Carver => First black student & first black teacher at Iowa State before his amazing career at Tuskegee
52
The Peanut story (Tuskegee)
  • 325 products from peanuts
  • >100 products from sweet potatoes
  • Carver never made nor sought any money for his discoveries
53
Why am I telling you this story?...
  • You might not be a Norman Borlaug
  • You might not be a George Washington Carver
  • You might not even be a Henry Wallace
  • But you can be, should be, are an Etta May Budd!
54
Now what is the most important part of your job?
  • Clinical care
  • Research
  • Education (mentorship)
55
We hope that you have been…
  • Energized
  • Empowered
  • Enthusiastic
  • Goal: Educate your educators
56
Thanks for your time & attention
