Five educational innovations
can be attributed either directly or indirectly to operant conditioning
principles:
(1) instructional
objectives
(2) programmed
instruction (and its offshoot, computer-assisted instruction)
(3) mastery
learning
(4) contingency
contracts
(5) applied
behavior analysis
Operant conditioning is
supposed to work on a system of reinforcement and punishment
(i.e., reinforcement for behavior to be increased, punishment for behavior
to be discouraged.) Punishment should be used effectively.

Instructional Objectives
In operant conditioning,
the terminal (or desired) behavior should be specified in precise, observable
terms before conditioning begins; instead of "instructional objectives,"
then, the ideal is a behavioral objective, with three specified components:
(1) an observable, measurable outcome; (2) explanation of the conditions
under which the behavior should be exhibited; and (3) the criterion for
judging the acceptable performance of the behavior. (e.g., On weekly
written spelling tests, the student will correctly spell at least 85% of
the assigned spelling words for the week.)
Advantages and
Usefulness of Objectives
Objectives help with clear
goal-setting for teachers trying to choose the most effective method of
teaching a lesson and for students trying to understand what they're supposed
to be able to do after the lesson. Objectives are easily communicated
between teachers, students, parents, etc. Objectives also facilitate
the evaluation of the student as well as the instructional program.
Instead of just lower level
skills, such as knowing or understanding (being able to define or translate
into your own words), students should also be doing things like applying
(using info. in a new situation); analyzing (breaking info. into its constituent
parts; synthesizing (constructing something new by integrating several
pieces of information); or evaluation (critiquing or judging the value
of info.).

Programmed Instruction (and CAI)
PI (programmed instruction)
is a technique for instruction involving, originally, a "teaching machine"
and, recently, computer programmed instruction (computer assisted instruction).
Typically, PI uses "frames," or discrete segments, with a small piece of
information and a question about it. The student responds to the
question and turns to the next frame to get the answer and the next small
piece of information, etc. Intrinsic to programmed instruction are
several concepts and principles based on operant conditioning, including
the following:
1. terminal
behavior -- goals of instruction are specified at outset
2. active responding
-- the student is required to make a response in each frame
3. shaping -- instruction
begins with info the student already knows; new info is broken up into
small pieces, and instruction proceeds through a gradual presentation of
increasingly more difficult pieces, with the terminal behavior gradually
shaped
4. immediate reinforcement
-- because of the gradual shaping process, it's highly probable that the
student will give correct answers to the questions asked; each correct
answer is reinforced immediately with feedback that it is correct

Mastery Learning
This is an approach to
learning in which a student must learn one lesson well before proceeding
to the next lesson. Mastery learning usually includes the following
components:
1. small, discrete
units -- each with a small amount of material
2. logical sequence
-- units are sequenced so that each basic concept is foundation to later
units (the process of identifying and sequencing course content, going
from simpler to more complex, is called task analysis)
3. demonstration of
mastery at the completion of each unit -- before going on, students
get feedback and reinforcement that they have "mastered" the content by
taking and passing a test
4. a concrete, observable
criterion for mastery of each unit -- mastery level is specified in
concrete terms (e.g., answering 90% of questions correctly)
5. "remedial" activities
-- activities to reteach or extra practice activities are provided for
students needing extra help or more practice -- students who don't exhibit
mastery on the first try have additional support and resources

Contingency Contracts
A contingency contract
is an agreement between a student and a teacher that specifies certain
expectations for the student (the terminal behavior) and the consequences
of the student's meeting those expectations (the reinforcer). The
formal structure and "one-at-a-time" goals of this type of approach seems
to be effective in addressing diverse problems such as poor study habits
and drug addition

Applied Behavior Analysis
Applied behavior analysis
-- also called ABA, behavior modification, behavior therapy, or contingency
management -- based on the assumption that behavior problems are the result
of past and present environmental circumstances, ABA encompasses a number
of procedures whereby an individual's present environment is modified to
promote the reinforcement of acceptable behaviors and the nonreinforcement
of inappropriate ones; can be used with individuals, small groups, or large
groups (notable types: group contingency, token economy with backup reinforcers).
Typical tenets of ABA are
as follows:
1. present and
desired (target) behaviors are specified in observable, measurable terms
2. an effective reinforcer
is identified and a specific intervention or treatment plan is developed
3. behavior is measured
both before and during treatment (using frequency counts, rate of response,
or time sampling (dividing time periods during which individual is being
observed into equal intervals, checking to see whether the targeted behavior
occurred in that interval, and what reinforcement or other behavior management
procedure was used)
4. the treatment is monitored
for effectiveness as it progresses and is modified if necessary
5. measures are taken to
promote generalization of newly acquired behaviors (one of the criticized
components because some of the behaviors don't generalize well)
6. treatment is phased
out after the desired behavior is acquired

Using
Punishment in Classroom Settings
-
time out -- a punishment
that involves placing the misbehaving individual in an environment with
no reinforcers (i.e., a dull, boring situation); a key is that the inappropriate
behavior must stop before the child is released from the time-out situation
(a negative reinforcer); release from time-out is contingent on appropriate
behavior
-
response cost -- withdrawal
of a previously earned reinforcer; appears to be most effective when combined
with reinforcement of appropriate behavior
-
reprimands -- scolding
or admonishing as punishment; reprimands are often more effective when
they are accompanied by eye contact or a firm grip -- or spoken quietly
in close proximity to the child being punished
-
restitution and overcorrection
-- restitution and overcorrection require people to take actions that correct
the results of their misdeeds. In restitution, a misbehaving individual
must return the environment to the same state of affairs it was in before
the misbehavior (e.g., a child who breaks a window must pay for a new one;
child who makes a mess must clean it up). Restitution is a good example
of a logical consequence, where the punishment fits the crime. There
are two types of overcorrection: (1) In restitutional overcorrection, the
punished individual must make things better than they were before the inappropriate
behavior (e.g., a student who throws food in the lunchroom has to clean
the whole lunchroom).
-
positive practice --
(2) In positive-practice overcorrection, an individual must repeat an action,
this time doing it correctly, perhaps in an exaggerated fashion (e.g.,
a student who runs dangerously down a corridor might be asked to go back
and walk (perhaps in slow motion) down the hall).

Guidelines
for Using Punishment Effectively
-
The punishment must be
punishing. True punishment decreases the response it follows.
Sometimes adults make assumptions about what consequences will be punishment,
but sometimes a common punishment might be reinforcing (e.g., the child
for whom time-out is a pleasure; the kid who hates school suspended for
nonattendance).
-
The punishment must be
strong enough to be effective, but not overly severe. Punishment
that is too short or mild is not effective (e.g., fines are not sufficient
deterrents for many drunk drivers; threat of getting a bad grade is not
sufficient to keep many students from not studying). Punishment that
is overly severe may have undesirable side effects, such as resentment,
hostility, or escape behavior, and may reappear at its original level once
the punisher has left the scene.
-
Punishment should be
threatened once before it is administered. People should
be warned ahead of time, since punishment is most likely to deter behavior
when an individual knows that the behavior will lead to punishment, what
that punishment will be, and that the punishment is, in fact, likely to
occur as promised.
-
The behavior to be punished
should be described in clear, concrete terms. Students should
understand exactly which responses are unacceptable. (e.g., students told
"disruption of the class is unacceptable" might not actually know what
"disruption" means, exactly, and if "getting out of your seat without permission"
is included, the student needs to know that).
-
Punishment should be
consistent. Punishment is much more effective when it is
a consistent consequence of a particular response. When a response
is punished only occasionally, the response disappears slowly, if at all.
-
Whenever possible, the
environment should be modified so that the misbehavior is less
likely to occur. The temptation to engage in a misbehavior should
be reduced or, if possible, eliminated. (e.g., people on diets should
not stock their kitchens with junk food; cheating on exams can be reduced
by having students sit apart from one another or by administering two different
forms of the exam)
-
Desirable alternative
behaviors should be taught and reinforced. Punishment is
more effective combined with reinforcement of appropriate behavior.
A misbehavior is more likely to be permanently suppressed when alternative
behaviors are reinforced, especially when those behaviors are incompatible
with the punished behavior. (e.g., if punishing playground aggression,
reinforce appropriate social behavior)
-
Whenever possible, punishment
should immediately follow the inappropriate behavior. Effectiveness
of punishment decreases dramatically when delayed, although if punishment
cannot follow the misbehavior, the punished behavior must be clearly described.
-
An explanation of why
the behavior is unacceptable should be given. Punishment
is more effective when reasons why certain behaviors cannot be tolerated
are given. (e.g., "When you talk without permission and when you
get out of your seat during quiet reading time, you keep other children
from getting their work done.") The advantages of this are that providing
the reasoning for the punishment lessens the critical factor of immediacy
in the punishment, increases the likelihood that similar misbehaviors are
also suppressed (the effect of the punishment generalizes to other behaviors),
increases likelihood that the misbehavior will be suppressed even when
the punisher is absent, and helps with older children's expectation that
they be told why they cannot engage in certain behaviors and are less likely
to be defiant when reasons are provided.
-
Some punishments that
are particularly ineffective and should be avoided. Not generally
effective and not recommended are physical punishment (especially with
older children), psychological punishment, extra classwork, and suspension
from school. Alternate to suspension is in-house suspension (in-house
time-out), which does not reward misbehaving students by removing them
from the school environment but prevents interacting with peers that most
students find rewarding.
-
Punishment should be
used sparingly. An effective punishment is one that does
not need to be administered very often to be effective. When punishment
is a frequent occurrence, the numerous disadvantages of punishment are
likely to appear (i.e., anger, resentment, avoidance, etc.).
