Learning Outcomes

As a result of this workshop training, participants will be able to:

1. Demonstrate an understanding of evidence-based practice

2. List one empirical study related to improved outcomes and instruction

3. Describe features of the TEACH-M instructional package

4. Apply the TEACH-M instructional package to clinical examples

Instruction Defined

Teaching (i.e., therapy, training, coaching, mentoring, etc.)Sharing knowledge/skills with othersIn this course…

Explicit, systematic instructionSevere brain injuryNew learning IS possible!

Rationale: Why focus on instruction?Focus of rehabilitation on training/teaching

Regardless of the treatment domain, we are all instructors

Maximizes client success/goal achievementNot all university training programs provide coursework dedicated to instructionHave to “do more with less”

e.g., less money, treatment time, etc.

Why focus on instruction?

Example: “Do more with less”Outpatient for TBIAverage # of visits 2005:

30-60 visits/calendar year, combining physical, occupational, and speech therapiesMinimal # of sessions with Oregon Health Plan (i.e., 1-2 per year for SLP)

Why focus on instruction?

“…in particular [the field of cognitive rehabilitation] has neglected for over two decades the accumulated wisdom in educational psychology, special education, etc. This neglect has cost billions of dollars and yielded countless hours of largely unsuccessful intervention for people with TBI. We have an opportunity to turn this around.”

Mark Ylvisaker, personal communication, 2003

Why focus on instruction?Teaching is complex

Teaching IS rocket science (Moats, 1999)

Information CAN be taught Instructor is responsible for learning

Frame problems around what instructor can control/manipulate*** Incorrect response is learner’s best attempt to be intelligent

More carefully taught = More easily learned

Rationale:Evidence-Based PracticeWhat is Evidence-Based Practice (EBP)?

“the conscientious, explicit, and judicious use of the current best evidence in making decisions about the care of individual patients”

Sackett, D. L., Rosenberg, W. M. C., Gray, J. A. M., Haynes, R. B., & Richardson, W. S. (1996). Evidence-based medicine: What it is and what it isn’t. British Journal of Medicine, 312, 71-2.

“the integration of best research evidence with clinical expertise and client values”

Sackett, D. L., Straus, S. E., Richardson, W. S., Rosenberg, W., & Haynes, R. B. (2000). Evidence-Based Medicine: How to Practice and Teach EBM. New York: Churchill Livingstone.

Evidence-Based Practice

Not a new phenomenonThink of “Efficacy” and “Accountability”

Focus on improving client outcomesMakes us better cliniciansRemember science of rehabilitation

Clinical scientist and Research scientistClinical work as a marriage between art and science (Apel & Self, 2003)

Evidence-Based Practice

EBP is a process for decision making

1. Identify need for clinical information2. Ask a searchable clinical question3. Search for the evidence4. Critically evaluate the evidence5. Integrate evidence with clinical

expertise and client values6. Evaluate effectiveness of treatment

Evidence-Based Practice

Integrate and make a decision for your individual client

Best available evidence

Client’s values and preferences

Clinician expertise

EBP

Evidence-Based Practice:Insufficient Research

Evidence

Focus: Provide a rationale for your decisionsTreatment should at least be theoretically groundedClinicians have a responsibility to track outcomes and document changesBottom Line:

Take data, Measure progress, and Document gains!

Integrate research evidence with clinical expertise and client’s values

Instruction

Common Types of InstructionTrial and errorMentorship/experiential learningExplicit, systematic instruction

Exchange of knowledge/skills from the instructor to the learner

Involves learning

Learning and Memory

Learning requires memoryTypes of memory

Short-term memory “Working” memory

Long-term memory“Fact” memory“Event” memory “Procedural” memory

Types of Long-Term Memory

”Fact-Event” memory (or “Explicit” memory): acquisition and intentional recollection of facts, concepts & events

“Procedural” memory: knowledge of procedures/skills or tasks without intentionally remembering the experience of learning

(Baddeley, 1995; Brandt & Rich, 1995; Tranel & Damasio, 1995)

Errorless Learning (EL)Brain injury generally does NOT affect “procedural” memory, but does affect “explicit” memory.Impaired “explicit” memory makes it difficult to remember and correct errors. Errors stick: “Trial and error” learning is therefore risky!

Goal of EL:Avoid errors while learning something new!!!

How do we achieve EL?

Errorless learning works by using high amounts of correct practice.Distributed practice (e.g., spaced retrieval) also facilitates EL.Target skill therefore becomes “routine”, “firm”, “solid”.

(Evans, et al., 2000; Wilson, Baddeley, Evans, & Shiel, 1994)

Direct InstructionDirect Instruction (DI):

well-established, systematic instructional methodology used across many different populations, particularly individuals with learning disabilitiesused across many different subject areas (e.g., reading, math, social skills)

Errorless learning is a key component of DI

DI components:* See Direct Instruction Strategies handout

Examples:Evidence in Support of DI/Errorless

Learning for Individuals with Cognitive Impairment

Research: Mozzoni & Bailey (1996) Improving training methods in brain injury

rehabilitation

Research Goal: To evaluate and improve the teaching effectiveness of therapists in an in-patient rehabilitation settingParticipants: Six therapists (speech, OT, recreation, nurse, cognitive rehab.) and five patients with severe TBI (Rancho Levels 5-6)Intervention: Daily feedback on therapists teaching skills using a checklist of specific behaviors Outcome measure: Patient performance on Functional Independence Measure (FIM)Level of Evidence: Level 2

Mozzoni & Bailey: Skills Checklist

Is the cuing clear?Is the patient attending to the therapist?Is the therapist using a task analysis?Is treatment consistent between sessions?Is therapist prompting systematically?Is the patient practicing the skill more than once?

Research:An instructional package

TEACH-MEvaluation of an instructional

sequence for persons with impaired memory and executive functions

(Ehlhardt, Sohlberg, Glang, & Albin, 2005)

Level 2 Evidence

TEACH-M!Task analysis: Know your content. What is the target skill?

Break it into small steps. Chain steps together.

Errorless learning: Keep errors to a minimum during the acquisition phase. Model target step(s) BEFORE client attempts a new skill/step. Carefully fade support. Don’t let an error sneak by! Demonstrate the correct skill/step right away and ask client to do it again.

Assess performance: (initial)-assess skills before treatment; (on-going) - probe performance at the beginning of teaching session and/or before introducing a new step.

Cumulative review: Regularly review previously learned skills.

High rates of correct practice trials: 5 trials is not enough! 30-50 or more is like it!

Metacognitive strategy training: self-evaluation of one’s own performance

Research QuestionsIs there a functional relationship between implementation of the E-Steps program and:

1. The percentage of e-mail steps learned, in sequence?

2. Are treatment effects maintained at one month following the cessation of treatment?

3. Do treatment effects generalize to use of a similar e-mail interface with added features (i.e., altered interface) and/or a computer game with no shared features?

4. How many training sessions are required to reach the criterion for mastery?

Methods:Materials & Task Analysis

Simple email systemNot a “live” system for this studyHypothetical partners (e.g., counselor)

Task Analysis1. Click on start2. Click on inbox3. Click on picture4. Read message/click on reply5. Click on answer (yes or no)6. Click on send7. Click on quit

Methods: E-Steps program (IV)Phase 1: review - model - practice Phase 2: metacognitive strategy training

(reflection-prediction using screenshots)“Which step(s) will be easy? Which step(s)will be difficult?”

Phase 3: spaced retrieval (immediate recall, 30 seconds, 1 minute, 2 minutes)

Phase 4: metacognitive strategy (reflection using screenshots)“Which step was easy? Which step was difficult?”

Program implemented 4-5x weekly
