INTRODUCTION
Empathy Teaching/Learning

DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Consider the following “alphabet” (60 secs):
Exercise: Now write my office phone#: 89425771 ?
Exercise 1
1. 2. 3. 4. 5.
6. 7. 8. 9. 0.

Exercise 1 (cont’d)
So what is the point? Random information is really hard to remember We learn (efficiently) by associating (building)
new unknown information / with (on) old known information
1. (One of the many) roles of the teacher is to build on known* knowledge [ empathy! ]
2. Knowledge is constructed as a result of the learner’s
activity
*/ assumed prior knowledge
Constructivism = base teaching on what the learner does

Empathy
About helping(/teaching) others:
Basically: empathy! Know/anticipate what your students know (/don’t know)!
"At man, når det i sandhed skal lykkes en at føre et menneske hen til et bestemt sted, først og fremmest må passe på at finde ham der, hvor han er, og begynde der.
Dette er hemmeligheden i al hjælpekunst. Enhver der ikke kan det, han er selv en indbildning, når han mener at kunne hjælpe en anden.
For i sandhed at kunne hjælpe en anden, må jeg forstå mere end han - men dog vel først og fremmest forstå det, han forstår. [ empathy! ]
Når jeg ikke gør det, så hjælper min mere-forståen ham slet ikke. Vil jeg alligevel gøre min mere-forståen gældende, så er det fordi jeg er forfærdelig stolt, så jeg i grunden i stedet for at gavne ham egentlig vil beundres af ham.”
-- “Brudstykker af en ligefrem meddelelse”, Kierkegaard, 1859

IMPERSONALIZATION
A language for teaching impersonalizes teaching
© CLAUS BRABRAND[ 11 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
A taxonomy / language for teaching impersonalizes teaching
Emotional detachment (aka. “dissociation”) The teacher is good/bad
identity: good/bad teacher The methods are good/bad
behavior: good/bad method knowledge: good/bad method
With dissociation: more capable of dealing with critique better to listen
to constructive advice (…just like with our research)

“SUSAN AND ROBERT”
Good student vs. Bad student

Consider two Students
Susan: Robert:
“It’s just the way the students are; either good or bad”
Note: this labelling (conveniently) defers reponsibility: In particular, we cannot do anything about it!
Good student
Bad student
“Good student–bad student” perspective:
© CLAUS BRABRAND[ 15 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Levels of Thinking about Teaching
Level 1: what students are “Blame-the-students” (Good vs. bad students)
Exam = “sorting good from bad students - after teaching”
Level 2: what teachers do “Blame-the-teachers” (Good vs. bad teachers)
Acquiring an armoury of teaching techiques and tricks
Level 3: what students (should) do Maximize likelihood of students using depth learning Minimize likelihood of students using surface learning
process + productperspective(teaching outcome)
© CLAUS BRABRAND[ 16 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
“Blame-the-Students”
Level 1: Unfortunately a predominant view: “Blame-the-students”:
“My students are lacking the ability to learn…!” “Why won’t they learn the interesting bits?” “So many bad students; they just don’t understand!”
Deferring responsibility: “Nothing’s wrong with my teaching; I state things clearly!” “I taught them (right); they didn’t learn!”
Level 3: Now, let’s instead: Focus on teaching process & product (“learning outcome”):
“what the student (should) do”…

Two Relevant Quotes
”Learning takes place through the active behavior of the student: it is what he does that he learns, not what the teacher does.”
Ralph W. Tyler (1949)
”If students are to learn desired outcomes in a reasonably effective manner, then the teacher’s fundamental task is to get students to engage in learning activities that are likely to result in their achieving those outcomes. […] It is helpful to remember that what the student does is actually more important in determining what is learned than what the teacher does”
Thomas J. Shuell (1986)
“Level 3 perspective”: Focussing on what the students (should) do:

DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Roles (Teaching/Learning Collaboration)
During learning period (i.e., before the exam): Teaching/Learning collaboration:
Student = “Learner” Learning responsibility
You = “Teacher” (To the best ability) aid students in learning
During the exam period: Student = “Performer”
Demonstrate what (s)he has learned
You = “Evaluator” (Neutrally) assess the students level of understanding

DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Returning to Susan & Robert:
Susan: Homo Sapiens Goal: likes to get to the
bottom of things; to reach understanding (often reflects about possibilities/ implications/applications..)
Characterized by: preference for depth learning spontaneously uses the
higher cognitive processes basically teaches herself (we
almost cannot prevent her from learning)
Robert: Homo Sapiens Goal: just wants to pass
exams; get a degree and get a decent job (doesn’t really care about learning in itself)
Characterized by: preference for surface
learning will only apply higher
cognitive processes if he really really has to
will cut any corner
Now we can do something about it (= Robert’s learning)!

COGNITIVE-LEVELS
“The SOLO Taxonomy”:
- to memorize, … vs …, to theorize
© CLAUS BRABRAND[ 22 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
“The SOLO Taxonomy”
Cognitive levels of understanding: SOLO 5 (aka. “extended abstract”):
theorize, generalize, hypothesize, …
SOLO 4 (aka. “relational”): compare, analyse, relate, apply, …
SOLO 3 (aka. “multistructural”): enumerate, describe, perform algorithms, …
SOLO 2 (aka. “unistructural”): identify, memorize, simple procedures, …
SOLO 1 (aka. “prestructural”): no understanding: misses point !

Often, examiners and censors distinguish “good” and “bad” student performancebased directly on this taxonomy (and often, without being consciously aware of it)!

Course Objectives
“What are the students supposed to learn”? State explicitly (as verbs) the skills they are to acquire
Makes it clear what they are supposed to be able to do They are able to check themselves against it

ALIGNMENT ()
Course objectives = exam assessment
© CLAUS BRABRAND[ 30 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Alignment ()
$2000 Question: “How do we make the students learn what we want
them to”?
Answer: “Alignment”:
Exam measurement := Course objectives ! …and let the students know this (!)
© CLAUS BRABRAND[ 31 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
e.g.- memorize
Alignment () Unaligned Course: Aligned Course:
Teacher’sintention
Student’sactivity
Exam’sassessment
Teacher’sintention
Student’sactivity
Exam’sassessment
e.g.- explain- relate- prove- apply
e.g.- memorize- describe
Phenomenography = learner’s perspective (not teacher’s intention) defines learning
Robert: will “deal with the test”:- “Are we supposed to learn this?”- “Is this going to be on the test?”
CS: “it commutes”

DEFINITION: GOOD TEACHING
Maximize #students doing (cognitively) high-level learning
© CLAUS BRABRAND[ 34 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Definition: “Good Teaching”
Definition:
“Teach so that Robert behaves like Susan”
Good news: We now know how to do this:
Explicitly defined course objectives (as verbs)! Alignment!!! Discourage surface-learning! Encourage depth-learning! “Less-is-more”: depth rather than breadth of coverage! ()
”Good teaching is getting most students to use the higher cognitive level processes that the more academic students use spontaneously”

DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Year 2005
Susan and Robert graduated 20 years ago (and both became teachers):
Susan has 20 years of teaching experience Reflective teacher (aka. “reflective practitioner”) i.e., reflects before, during, and after teaching courses
Robert has 1 year of teaching experience
…repeated 19 times ! Ok no need to change Bad blame-the-students / blame-the-administration

MOTIVATION BEYOND GRADES
Explain how the knowledge may impact “daily life” (which advantages)
© CLAUS BRABRAND[ 37 ]
DAIMI, UNIVERSITY OF AARHUS, DENMARK NOV 25, 2005
Motivation Beyond the Exam
Motivational problem: “Why bother learn the course material?”:
Tell them why it is important to learn these things: How could these skills benefit them in their work/life/…
(focus on advantages)

What discerns a really good programmer from one that is not so good is the capability of moving (consciously or unconsciously) between the concrete world of programs and the abstract world of semantic models (via abstraction and concretization).
Specifically, such a programmer is capable of (consciously or unconsciously): - 1) abstracting programs into models - 2) reasoning about the models - 3) concretizing the insights back into the world of programs

Notes on Skill Acquisition
From the world of psychoanalysis [Maslow]: Skill acquisition progresses according to the following
stages of learning: 1. Unconscious incompetence 2. Conscious incompetence 3. Conscious competence 4. Unconscious competence
5. Capacity for moving consciously between stages 3. and 4.: [ required by a teacher ]

(My Personal) Bag of Tricks
“Bag of Tricks”: Positive (and respectful) answers Reflective timeout (1-2 minutes neighbor discussion)
Questions sanctioned (“approved” as relevant by neighbor)
Better questions (they thought and talked about them)
Jokes (to ease atmosphere) Competitions (to stimulate creativity+provide incentive) Variation (to keep interest and focus) Interaction (to activate the students) Metaphores (to associate with prior known knowledge) Breaks-by-need* (*/ not your need)
However, for these kind of things:ask somebody with more teaching experience…
Mazur: peer-instruction
