Theoretical Framework Science & Values Chris Borgmeier, PhD Portland 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 Learning Theories Behaviorist & Constructivist Constructivism as a Learning Theory • “Discovery Learning” or “Experiential Learning” learning involves constructing one's own knowledge from one's own experiences • Promotes a student's free exploration within a given framework or structure • Teacher acts as a facilitator who encourages students to discover principles for themselves and to construct knowledge by working to solve realistic problems. Constructivism: What the researchers say • Based on the results of their research, these authors do not support the idea of allowing novices to interact with constructivist learning environments contexts – Paas, 1992; Moreno & Mayer, 1999; Mousavi, Low, & Sweller, 1995; Chandler and Sweller, 1992; Sweller & Cooper, 1985; Cooper & Sweller, 1987 • Ill-structured learning environments rely on the learner to discover problem solutions. Novices should be taught with "well-structured" learning environments. – Jonassen, 1997 Constructivism: What the researchers say • After a half century of advocacy associated with instruction using minimal guidance, there appears no body of research supporting the technique. In so far as there is any evidence from controlled studies, it almost uniformly supports direct, strong instructional guidance rather constructivist-based minimal guidance during the instruction of novice to intermediate learners. Even for students with considerable prior knowledge, strong guidance while learning is most often found to be equally effective as unguided approaches. Not only is unguided instruction normally less effective; there is also evidence that it may have negative results when student acquire misconceptions or incomplete or disorganized knowledge” – Kirschner, P.A., Sweller, J. & Clark, R.E. (2006). Why minimal guidance during instruction does not work: An analysis of the failure of constructivist, discovery, problem-based, experiential, and inquiry based teaching.

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 ABC 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 Student is asked to do a math problem in front of the class Student tries to do the problem at the board, but struggles NEXT DAY Student is asked to do a math problem in front of the class What happens today??? C Peers laugh at student and one says aloud, “that one is so easy” Reinforcing Consequence AB C Rewarding or Desired Consequence If the consequence is rewarding/desired, the subject learns the behavior is functional for getting what they want Behavior Increases in the Future Punishing Consequence ABC Punishing or Undesired Consequence If the consequence is punishing/undesired, the subject learns the behavior is not functional for getting what they want Behavior Decreases in the Future ABC’s of Instruction Across the Continuum of Learners Instruction Antecedent Behavior Consequence Prompt Student Response Teacher Feedback Mainstream “What is the capital of Sweden?”…. Bueller, Bueller Student thinks “Stockholm” Sporadic verbal praise Student self reinforcement “I got it right!” Direct Instruction Reading Showing card with word “cat” – saying “this word is ‘cat’, what word?” “cat” Yes – that word is cat; “c-ar” No, this word is cat Significant Disabilities “Choosing food at lunch” Most to least prompting -physical guidance Student Response (hand over hand) -Physical -Gestural DIFFERENCES across Continuum -verbal - # of trials to mastery - explicitness of instruction Reinforce response -tangible reinforcer -verbal praise -access to natural reinforcer “get lunch” Reinforcing Consequence AB C Rewarding or Desired Consequence If the consequence is rewarding/desired, the subject learns the behavior is functional for getting what they want Behavior Increases in the Future A-B-C A-B-C A-B-C A-B-C A-B-C A-B-C Instruction & Support Student Independence Phases of Learning/Teaching Alberto & 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 reinforcement A-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 settings A-B-C Reinforcement Continuum & Phases of Teaching Stages of Learning/Teaching Acquisition 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 praise Can usually anticipate that academic success or social benefits will continue to maintain desired behavior.
