Theoretical FrameworkScience & Values
Chris Borgmeier, PhDPortland State University
Questions• How should special educators make decisions about choosing
practices to support student needs?
• Why are research, theoretical frameworks and data each important for guiding decision making and choosing professional practices in special education?
• How does research inform practice?
• How do I identify research based practices when I need interventions for a student challenge?
Research Based Theoretical Framework
• What if there isn’t really a research-based curriculum or intervention for the individual needs of my student?– No random control trials; no group research– Look to single case research
• Application of Research Based Principles• Grounding in a sound theoretical framework
Behavioral or Learning TheoryAssumptions of Behavioral Theory• Behavior is Learned• Focus on the observable and measurable• Behavior is related to the environment in which it occurs• Behavior serves a purpose• Focus on how environmental variables can be manipulated to effect changes in
behavior & learning• Measure student outcomes & learning
• Educational approaches that have emerged from behaviorism include:– applied behavior analysis– Functional assessment– curriculum based measurement and progress monitoring, and– Direct instruction have emerged from this model– Discrete Trial Training– Modeling, shaping, fading, reinforcement, contract, extinction, etc.

Foundations of Behavior
Behavior
• Identify the Target Behavior– Desired Behavior or Non-desired Behavior
• Behavior must be identified so that it is observable & measurable– Define the behavior so that someone else could go
into the room and both of you could measure the behavior without question
Operational Definition
EXAMPLESWhat the Behavior Looks Like
NON-EXAMPLESWhat the Behavior Does NOT Look Like
Provide a range of examples •try to provide examples that delineate the boundaries of what the behavior looks like
Provide a range of non-examples
• try to provide examples that delineate the boundaries of what the behavior does not looks like
Behavioral Definition: Observable & Measurable definition
Operational Definition
EXAMPLESWhat the Behavior Looks Like
NON-EXAMPLESWhat the Behavior Does NOT Look Like
Student is:• Sitting at desk working with feet on floor and hands on work•Standing in line with hands at side and without bumping into other students•Sitting on floor and gently nudges another student by accident•Teacher asks students to hand out books to class•Playing tag at recess and gently tags another person to be it
Student is:•Kicking peer under the desk or poking the peer to get their attention•Hold on to another students arm so they can’t get away from them in line•Purposefully run into or push a student sitting next to you on the floor•Throws a pencil at another student when the student needs a pencil•Chases a peer during recess and touches them after the peer asks you to stop
Hands, Feet and Objects to Self: Student does not touch other students with their hands, feet or objects, with intent to hurt, bother or get peers attention at inappropriate times
ABC’s of Understanding BehaviorOperant Conditioning
• What happens before (A or antecedent) the
behavior occurs? – Trigger
• What is the behavior (B)?• What happens after (C or consequence) the
behavior occurs? – Response or Outcome of the Behavior
A B C
Antecedents What triggers the behavior?
• What happens immediately preceding the problem/target behavior?
• What triggers the behavior, be specific...– What activity?– What peers?– What tasks?– Describe in detail
• If you wanted to set up the student to engage in the problem behavior, what would you have do?
Consequence What is the response to the behavior?
• What happens immediately following the behavior?– How do peers respond?– How do the adults respond?– What are the consequences for the student?– How many times out of 10 do each of these responses
occur following the problem behavior?
• What is the student gaining as a result of engaging in the behavior? – How is it paying off for the student?
Learning
A B C
Student Learns through repeated experience, that under these specific Antecedent conditions, if I engage in this Behavior, I can expect this Consequence
Learning & ABC
A B CStudent is asked to do a math problem in front of the class
Student tries to do the problem at the board, but struggles
Peers laugh at student and one says aloud, “that one is so easy”
NEXT DAYStudent is asked to do a math problem in front of the class
What happens today???
Reinforcing Consequence
AB CIf the consequence is rewarding/desired, the subject
learns the behavior is functional for getting what they want
Behavior Increases in the Future
Rewarding or Desired Consequence
Punishing Consequence
A B CIf the consequence is punishing/undesired, the subject
learns the behavior is not functional for getting what they want
Behavior Decreases in the Future
Punishing or Undesired Consequence
ABC’s of InstructionAcross the Continuum of Learners
Antecedent Behavior Consequence
Instruction Prompt Student Response Teacher Feedback
Mainstream “What is the capital of Sweden?”…. Bueller, Bueller
Student thinks “Stockholm”
Sporadic verbal praiseStudent self reinforcement “I got it right!”
Direct Instruction Reading
Showing card with word “cat” – saying “this word is ‘cat’, what word?”
“cat”
“c-ar”
Yes – that word is cat;
No, this word is catSignificant Disabilities
“Choosing food at lunch”
Most to least prompting-physical guidance (hand over hand)-Physical-Gestural -verbal
Student ResponseReinforce response-tangible reinforcer-verbal praise-access to natural reinforcer “get lunch”
DIFFERENCES across Continuum- # of trials to mastery- explicitness of instruction

Student Independence
Phases of Learning/TeachingAlberto & Troutman, 2009
• Acquisition – student’s ability to perform a newly learned skill/response to some criterion of accuracy
• Fluency – describe the rate at which students accurately perform a response; learner begins to build speed & efficiency in use of the skill or knowledge (but may not remember skill/knowledge over time without prompting)
• Maintenance – student is able to recall & use the skill/ knowledge with a high rate of accuracy over more extended spans of time with limited review
• Generalization – student generalizes skill or knowledge to novel contexts and as prior knowledge for learning new information
Acquisition Phase
• Acquisition – student’s ability to perform a newly learned skill/response to some criterion of accuracy– Strong use of reinforcers– Regular prompting & error correction– Modeling & Guided practice
• Model-Lead-Test/Model-Prompt-Check/I do-We do-You do
• Important to have critical background knowledge & prerequisite skills
A-B-C
Fluency• Following skill acquisition -- focus on
improving the RATE at which the learner performs the behavior
• What is an appropriate rate required for functional performance?– Reading, bus money, small talk, etc.
• Teaching Strategies– Frequent structured practice– Fading to intermittent reinforcementA-B-C
Maintenance
• Once learners can perform a skill fluently, it is important to maintain the skill over time– What
• Teaching Strategies– Make sure you are teaching functional/useful skills– Student access to natural reinforcers– Over-learning– Delayed reinforcement A-B-C
Generalization• Learners can use skill across settings other than the initial
instructional conditions– Train for generalization v. Train & Hope
• Teaching Strategies– Vary training across (Antecedent stimuli):
• Settings• People• Signals/Prompt types
– Teach the universe of examples– Intermittent reinforcement w/ link to natural reinforcers (Consequences)– Reinforce occurrences of generalization– Reinforce response across settingsA-B-C
Reinforcement Continuum & Phases of Teaching
Stages of Learning/TeachingAcquisition Fluency Maintenance
Continuous Intermittent…………fading…Rates of Review & Reinforcement
Continuous – provide reinforcement/corrective feedback on every occurrence of behavior – reinforcement may be tangible paired w/ verbal praise
Intermittent – fade tangible, continue w/ intermittent verbal praiseCan usually anticipate that academic success or social benefits
will continue to maintain desired behavior.
