Unit 4: College Teaching
• Behavioral analysis of college teaching and
student studying behavior
– Article by Dr. Jack Michael
• Why do PSY professors administer more exams and
require more assignments than professors in other
departments typically do?
• Why do I structure PSY 4600 the way I do with study
objectives, frequent essay examinations and hand
out a grade sheet
• Why, from a behavioral perspective, might your
study behavior differ in this class vs. other classes?
• Why do some (most of us) procrastinate - studying
for exams, writing papers, preparing conference
presentations, etc?

Introduction/Overview to the Michael article
• The teaching technology discussed in the article is
relevant for the “typical” college class with a course
enrollment of 35-40 or more and a clear “factual content.”
• It is not relevant for fine arts (dance, sculpting, painting,
writing) or other skill training such as public speaking,
mechanics, etc.
• While this technology can be used with small classes (15
or fewer students), there are also methods that can be
equally effective
• Most university classes at colleges and universities are
the type discussed in the article
4
Overview of Michael article, cont.
• Begins by discussing student motivation to study.
That is, what types of factors motivate students
to study hard?
• He discusses a number of factors that are often
mentioned by individuals (intrinsic interest in the
subject matter, approval/disapproval of others in
the study setting, long-range payoffs of learning
the material, etc.)
• He argues against each one, concluding that the
course grade is the only effective motivational
variable and the only one over which the
instructor has control.
5
Overview, cont.
• However, even the grade will not be an effective
motivator if the grade is not important to the
student
• He further states that if the grade is not important
to the student, then there is nothing an instructor
can do to motivate students to study
• Many say that grades should not be emphasized
- Michael disagrees with that perspective - the
grade is the only motivative factor that the
instructor has under his/her control and thus
should be emphasized
6
Overview cont.
• Next, he describes how to structure a course so
that the course grade is an effective motivator
• Three factors that must be present in order for
students to study hard (SO 12, but stated
positively):
– The grade must be important to the student
– The exam/assignment grades must be closely
(and explicitly) linked to the course grade; and
– Studying must be closely (and explicitly) linked
to the exam/assignment grades
(how many, assignment/quiz, have no idea how it relates to final grade - 10%, 20%,
maybe checkmark; how many I didn’t study at all, aced the test; I studied very hard
and didn’t have a clue? 2 exams - chapter 4 - graduate course - didn’t know passed/failed)
7
SO 1: Creativity?
• This type of course structure is very controversial and
has been criticized for a number of reasons
• The first criticism: This type of course does not teach
creativity or new knowledge, but only teaches
students how to parrot back old knowledge.
• Michael’s response?
Creativity requires an extensive familiarity with what is
already known - an extensive knowledge base about which
one can be creative.
For example, If you don’t understand reinforcement, punishment,
shaping, etc., you cannot create an effective instructional system or
develop an effective training program for individuals with developmental
disabilities.
(need to know the basics so you have something to be creative about)
8
SO 2: What is the two for one rule?
What does it imply for getting an A or a B?
• In order to get a C in a course, students should
spend 2 hours outside class studying for every
hour in class.
– 3 credit hour course: 2 x 3 = 6 hours outside
of class studying (each and every week) to
get a C
– Full credit load of 12-15 credit hours,
students should be studying 36-45 hours per
week for C-level performance
– MORE than 2 hours of study per credit hour
should required for an A or B. For example, 3
hours outside per credit hour, 9-10 hours.
(most don’t require that, this class - 6 hours per unit)
9
SO 3: What are two main problems with intrinsic
interest in the subject matter as a motivational factor?
• While the subject matter may indeed be interesting
to students, it is usually not sufficiently interesting
to maintain the amount of study required to master
the material
– Love behavior analysis, love 460, but that is not likely to
maintain 9-12 hours of studying each week
• Competing activities that are not postponable
while studying is. You can “always study tomorrow”
- but sometimes tomorrow never comes
– Friend drops by - let’s go out
– Baby/child gets sick
– Football game/play isn’t available at any other time
(in general, second reason is main reason)
10
SO 4: Why is it that short-term advantages from the
newly acquired material do not motivate studying?
• Many content courses, unlike automobile
mechanics, do not have many short-term
advantages to the student; rather
• They are important for further learning
– You can’t run before you can walk
– You can’t master the material in 460 unless you
have mastered the material in 360
– You can’t master algebra unless you master
arithmetic
(Both points are important if I ask this on the exam!)
11
SO 5:
Briefly describe the weakness of longrange payoffs related to the details of the
study assignment.
Note: the answer is not the delay or temporal
remoteness, even though that is a problem as well.
• It is easy to believe that you can contribute to the
human condition - that is, be a successful
behavior analyst - without understanding the
specific details of the study assignment
– It is easy to believe that you can be an effective human
service worker, OBM practitioner, clinical psychologist,
etc. without knowing SOs 5, 14, 20 and 26 from Unit 4
in Dickinson’s PSY 460.
12
SO 6: So why are grades the best motivational factor
to motivate student studying?
• It is the one motivational factor over which the instructor
has control - the only one (we can’t control intrinsic
interest, we can’t control whether others in the
environment support scholarly performance, etc.)
• It can be easily related to the details of the study
assignment (we can make SOs 5, 14, & 20 from U4
important by relating them to the exam/assignment)
• It is a factor of considerable strength - that is, it is
important to most students as evidenced by the intensity
of study/work right before an exam or right before an
assignment is due
13
SO 7: Vicious vs. Friendly Competition and their
relationship to norm-referenced vs. criterionreferenced grading practices.
• Many criticize emphasizing grades because it generates
“competition” and competition is bad.
• Michael distinguishes between “vicious” and “friendly”
competition, and agrees that “vicious” competition is,
indeed, bad, but “friendly” competition is not.
• He then describes grading practices that produce “vicious”
competition and those that produce “friendly” competition.
• Norm-referenced grading practices produce vicious
competition and hence should not be adopted, while
criterion-referenced grading practices produce “friendly”
competition which is OK.
14
SO 7: Norm-referenced grading produces vicious competition
• Norm-referenced grading
– The grade you receive depends not only on your grade
but the grades of other students in the class
– Grading on a curve: 10% of the students get As, 20%
get Bs, 50% or so get Cs
– If one student gets an A, it decreases the opportunity
for another student to get an A
– This produces vicious competition between students;
you may be happy when someone doesn’t get an A or
a B; you are not as likely to help someone - if you do,
that person may get an A, which decreases the
opportunity for you to get an A
– In fact, some students may actually engage in
behaviors that will harm another’s student chance to
get an A (steal relevant books from the library)
(physio course, comp exams)
15
SO 7: Criterion-referenced grading produces friendly
competition
• Criterion-referenced grading
– The grade you get depends only on your grade; not on
the grades other students get
– Dickinson’s PSY 460 grading practices; any student
who gets 92% of the points, gets an A.
– Friendly competition: Student wants to have the
highest point score in the class or a student wants to
“beat out” another student.
– But this does not produce the type of competition that
makes a student rejoice in the misfortune of other
students or refuse to help another student because it
might decrease his/her own grade.
16
SO 8: Study procrastination scallop
• Many people maintain that an exam or assignment is an
example of a FI schedule of reinforcement, which produces
the typical scallop of responding. (not much behavior in the
beginning of the interval, more and more behavior as the
interval progresses and reinforcement gets close).
• Not so! And the reasons are the same as the reasons we
examined last unit with respect to why a paycheck is not an
example of a FI schedule.
• So how do we explain the scallop in studying/working that
occurs right before the exam?
• How is that scallop behavior related to the exam grade and
the course grade?
17
SO 8 Continued: Procrastination Scallop
• To understand this, it helps to know that the analysis
Michael presents is a molecular analysis.
• Underlying position that if a consequence follows a
behavior by more than 5 to 60 seconds, it is not a directacting contingency; that is, that consequence cannot
directly affect the behavior as reinforcement, punishment,
etc.
• Rather the effect that the consequence has is due to other
variables, such as verbal behavior.
• Michael is a molecular behavior analyst (as most others in
the department) and thus explains the procrastination
scallop using a molecular analysis where the consequence
of studying must occur within 5 to 60 seconds after the
behavior of studying
18
SO 8: Procrastination Scallop, A molecular behavioral analysis
• The relationship between two factors affects
studying (Note carefully, not just one or the other!)
– Task completion: how much of the task the student has
completed
– Time passage: the time left before the exam or
assignment
• Task completion and time passage together
determine the aversiveness of the situation at any
point in time in the interval relevant to the
exam/assignment
(be careful not to put this in your own words)
19
SO 8 Continued
• To have completed most of the task and have a good deal
of time left is “safe” or “nonaversive”
• But to have completed very little of the task and have very
little time left is a condition that is dangerous or “aversive”
• It is the aversiveness that generates escape behavior
• Usually, the only relevant form of escape under these
circumstances is studying (or working on the assignment)
• The reinforcement for studying is the escape from the
aversiveness - the change in status to a less “dangerous”
condition with respect to the task-time relationship
• That is, the studying behavior decreases the existing
aversive condition - the decrease in the aversiveness is an
immediate negatively reinforcing consequence
20
SO 8: What reinforces studying?
• The reinforcement for studying is NOT the avoidance of a bad
grade on the exam/assignment
– The grade is too delayed, it does not occur within 5 - 60 seconds after
studying
• To repeat: The reinforcement for studying is the decrease in
the pre-existing aversive condition; immediate negative
reinforcement (escape)
MO (aversiveness):R (studying)-->Sr- escape
(decrease in aversiveness)
As soon as you study, there is a decrease in the aversiveness.
21
SO 8: What produces the scallop? That is why do (most)
students study more and more as the time interval passes?
• Because the aversiveness increases as the time
interval passes and they have not completed the
task/assignment
• That is, the pre-existing aversiveness becomes
stronger and stronger the closer the exam if
students have not completed the assignment.
(last slide on this)
22
SO 9: End-of-Course Activity
Why does an end-of-course activity (like a final exam or
paper worth 50%-75% of the student’s grade) weaken the
relation between the exam grades and the course grades?
Students can quite correctly believe that a low score on an
earlier exam or assignment can be compensated for by a
high score on the final exam or paper.
But what often happens? You run out of time because all of
your courses “kick in at the end.”
So no final exam in Dickinson’s PSY 460!!!
23
SO 10: Reasons professors give for their unwillingness to
clearly specify what is going to be on the exam
• Many professors are highly critical of study objectives on
the grounds that we are “spoon feeding” students.
• Professors often give two reasons for not wanting to specify
what is going to be on the exam
– You will only learn what the professor tells you to learn;
without specification you will learn all of the other things
you wouldn’t learn if you didn’t know what was going to
be on the exam
• Dickinson says not so! If you are examined over 4-5 chapters,
do you really learn everything in those 4-5 chapters?
– Part of the scholar’s repertoire consists of bringing order
out of chaos and dealing with the instructor’s vague
assignments is a good opportunity to learn this skill
• Not so again!!! (read material out of “interest”)
24
SO 11: In large enrollment classes what controls
attendance and what does NOT control attendance?
• What does control attendance?
How essential the lecture material is for doing well
on the exam - (note material in red!)
• What does NOT control attendance?
How interesting or inspirational the lectures are
Faculty do not have to do “dog and pony shows”
to get students to attend class.
Of course, all things being equal, interesting is
better than boring!
(shy)
25
SO 12: The three conditions under which the threat
of a low grade will NOT motivate studying
• If the grade is not important to the student
• The relation between the exam grade and the
course grade is not clear
• The relation between studying for the exam
and the grade on the exam is not clear
26
SO 14: Exam frequency and motivation to study
Provide two reasons why exams that are given once every three
weeks (let alone two exams per semester) will not have the same
motivational effect as exams that are given weekly.
1. The procrastination scallop: most students will wait to
study until the week of the exam
If I require 6 or more hours of outside studying for each
exam (for a C), if I gave an exam every three weeks
instead of every 1 1/2 weeks, it would require 12 or more
hours of study. If I gave just a mid-term and final, that
would be about 7 weeks or about 4.5 units, which would
require 27 hours or more of studying.
It is absurd to think that students will spend 27 hours
studying for the exam during that one week.
(one reason why professors use norm-referenced grading - no one does well)
27
SO 14: Second reason why exams that are given
once every three weeks (let alone twice a semester)
will not have the same motivational effect as weekly exams.
2. I have 1 1/2 hours for the exam, regardless of how often I
give the exams. If I gave an exam only once every three
weeks, I could not sample as much material from the
study objectives - that is I could not ask questions over
as many of the study objectives
– Why and how does this affect student studying?
Students know that I cannot test over all of the study
objectives, hence they will begin to try to guess which
ones I will ask and not study all of the objectives.
They will “gamble” about which items I will have test
questions over
(also less accurate assessment for me, but that is not related to student studying, faculty
Who give out 70 or more SOs for the exam and then only ask questions on very small
28
Proportion)
SO 15: Why learning can’t be fun and easy
• Many argue that learning should be fun and easy.
Not so, says Michael. He says it can’t be fun and
easy for two reasons.
– Intensity: there is too much to learn in too little time
– Assessment: there is a chance that the student will not
get the grade he/she wants on the exams and
assignments
Note carefully, it is NOT simply that the exams and
assignments are given - if every student got an A on
every exam/assignment, then assessment would not
cause students a problem
(Learn each factor and be able to explain them.)
29
Not for exam but why should grades be
emphasized?
Grades are the primary motivative variable,
which means that current standing in the
class and progress toward the final grade
should always be clear and frequently
brought to the student’s attention.
Hence, the grade sheet.
