challenging subjects.
2001
No Child Left
Behind
By 2014 every student
will be at grade level.
Instructional methods
will be scientifically
based.
Educators will be held
accountable for
outcomes.
Everybody’s Talking
• Teacher accountability often offered as solution for
education troubles.
• Numerous proposals to pay and evaluate teachers
based on student performance.
o Proposals usually linked to performance on high stakes
tests.
Function of Accountability Systems
• Assure that all students are benefitting from
educational services.
• Student performance primary source of feedback to
educators about effects of interventions.
Scope of the Problem
Research to Practice
• Gap concern in many
disciplines.
• Education is not excluded.
• Scientist/Practitioner model
aimed to close the gap.
Gap or Chasm?

Research to Practice Issues
• The lag time from efficacy research to
effectiveness research to dissemination is 10-20
years. (Hoagwood, Burns & Weisz, 2002)
• Only 4 of 10 Blueprint Violence Prevention
programs had the capacity to disseminate to 10+
sites in a year. (Elliott & Mihalic, 2004)
How Big is the Gap?
550 named interventions for children and adolescents
Empirically evaluated
Behavioral
Kazdin (2000)
Cognitivebehavioral
Evidence-based interventions are less likely to be used than interventions for
which there is no evidence or there is evidence about lack of impact.
Goals for Evidence-based Practice in Education
• At its core the EBP movement is a consumer
protection movement.
o It is not about science per se.
o It is a policy to use science for the benefit of
consumers.
o “The ultimate goal of the ‘evidence-based movement’
is to make better use of research findings in typical
service settings, to benefit consumers and society….”
(Fixsen, 2008)
How is Education to Increase the Use of
Evidence-based Practices?
• No Child Left Behind (NCLB) requires that
interventions used to improve educational
performance are based on scientific research.
o In NCLB there are over 100 references to scientific
research.
• Individuals with Disabilities Education Improvement
Act [IDEIA] (2004) requires interventions that are
scientifically based instructional practices.
How is Education to Increase the Use of
Evidence-based Practices?
• Specific requirements of IDEIA include:
o Pre-service and professional development for all who
work with students with disabilities to ensure such
personnel have the skills and knowledge necessary to
improve the academic achievement and functional
performance of children with disabilities, including the use
of scientifically based instructional practices, to the
maximum extent possible.
How is Education to Increase the Use of
Evidence-based Practices?
• Scientifically based early reading programs, positive
behavioral interventions and supports, and early
intervention services to reduce the need to label
children as disabled in order to address the learning
and behavioral needs of such children.
How is Education to Increase the Use of
Evidence-based Practices?
• The Individualized Education Program (IEP) shall
include a statement of the special education and
related services and supplementary aids and
services, based on peer-reviewed research to the
extent practicable, to be provided to the child, or on
behalf of the child, and a statement of the program
modifications or supports for school personnel that
will be provided for the child.
How is Education to Increase the Use of
Evidence-based Practices?
• In determining if a child has a specific learning
disability, a local education agency may use a process
that determines if a child responds to a scientific,
research-based intervention as part of the evaluation
procedures.
The Ethical Basis
• Most national psychological and educational
organizations have ethical standards requiring
science-based practices to address problems.
o American Psychological Association Ethical Standard 2.04:
 Psychologists’ work is based on the established scientific and
professional knowledge of the discipline.
The Ethical Basis
• National Association of School Psychologists
o Standard III F 4.
 School psychology faculty members and clinical or field supervisors
uphold recognized standards of the profession by providing
training related to high quality, responsible, and research-based
school psychology services.
The Ethical Basis
• National Association of School Psychologists
o
Standard IV 4.
 School psychologists use assessment techniques, counseling and
therapy procedures, consultation techniques, and other direct and
indirect service methods that the profession considers to be
responsible, research-based practice.
The Ethical Basis
• Behavior Analyst Certification Board
o Standard 2.09a
 The behavior analyst always has the responsibility to recommend
scientifically supported, most effective treatment procedures.
Effective treatment procedures have been validated as having both
long-term and short-term benefits to clients and society.
o Standard 2.09b
 Clients have a right to effective treatment (i.e., based on the
research literature and adapted to the individual client).
Another Ethical Responsibility
• Education services are largely funded through public
dollars (taxpayers dollars).
• There is an implicit assumption that the money will
be spent for the public good.
• A fiduciary responsibility exists when one person or
organization is charged with managing another
person’s money.
Another Ethical Responsibility
• The primary responsibility of a fiduciary is to act
solely for the benefit of the other party.
• Being a fiduciary carries the weight of ethical
conduct.
• Those of us charged with providing education
services have a fiduciary responsibility to assure
that the taxpayers are receiving the greatest
possible return on their investment.
How Do We Meet Our Fiduciary Responsibility?
• Interventions that have an evidence base are more
likely to produce positive effects for students.
o Does not assure positive outcomes but increases the
probability.
How Do We Meet our Fiduciary Responsibility?
• The impact of a non-evidence based intervention
is unknown.
o Using a non-evidence-based intervention when
evidence-based interventions available may constitute
unethical practice.
o Use a non-evidence based intervention should be
considered research
 All of the safe-guards afforded research participants and their
families should be in place.
o Conducting research with tax-dollars provided for
education services may constitute a violation of our
fiduciary responsibility.
Becoming Evidence-based
• Clearly, the intent of Congress, the U.S. Department
of Education, and Office of Special Education
Programs is to rely on interventions that have a
scientific basis.
• Professional organizations place great value on
scientific knowledge.
• What does it mean to be evidence-based?
What is Evidence-based Practice?
• Evidence-based practice has its roots in medicine.
o Movement has spread across major disciplines in
human services:
 Psychology
 School Psychology
 Social Work
 Speech Pathology
 Occupational Therapy

What is Evidence-based Education?
• The term “evidence-based” has become
ubiquitous in last decade.
o Often used interchangeably with empirically supported
and best practice.
o No consensus about what it means.
o At issue is what counts as evidence.
o Federal definition emphasizes experimental methods.
 Preference for randomized trials.
 Definition has been criticized as being positivistic.
Identify
What Counts as Evidence?
• Ultimately, this depends on the question being
asked.
o Qualitative methods are best for answering social
validity questions.
• In EBP the goal is to identify causal relations
between interventions and outcomes.
o Experimental methods do this best.
Identify
What Counts as Evidence?
• Even if we accept causal demonstrations to be
evidence, we have no consensus.
o Randomized Clinical Trials (RCT) have become the “gold
standard.”
o There is controversy about the status of single subject
designs.
 Most frequently criticized on the basis of external validity.
 WWC has recently established standards for SSDs .
 No well established method for calculating effect sizes.
Identify
Distinguishing Between Evidence-based and
Empirically Supported
• Evidence-based refers to practices that have been
validated through a systematic review.
o Can involve meta-analysis.
o WWC reviews are systematic reviews.
• Empirically supported refers to practices that have
received support in peer reviewed journals.
o Have not been systematically reviewed to establish
strength of evidence.
Identify
Applying Best Available Evidence Construct
• If validated intervention available adopt it.
o Assuming it is appropriate to context.
• If no validated intervention select empiricallysupported intervention.
• If no empirically-supported interventions develop
intervention based on principles.
o Principles of scientific reading.
o Principles of behavior.
Identify
Applying EBP Framework
• Professional judgment involved at all levels of
selection an intervention.
• Interventions must fit competencies of those
implementing.
• Interventions must be acceptable to consumers and
fit values.
Identify
How Are Evidence-based Interventions
Identified?
• Identification is more than finding a study to
support an intervention.
• Identification involves distilling a body of
knowledge to determine the strength of evidence.
Identify
How Are Evidence-based Interventions
Identified?
• Distillation requires standards of evidence for
reviewing the literature.
o Standards specify:
 the quantity of evidence
 the quality of evidence

Identified?
• Two approaches to validating interventions
o Threshold approach:
 Evidence must be of a specific quantity and quality before an
intervention is considered evidence-based.
 What Works Clearinghouse
» Meets evidence standards.
» Meets evidence standards with reservations.
» Does not meet standards at this time.
o Hierarchy of evidence approach:
 Strength of evidence falls along a continuum with each level
having differential standards.

Choosing Between False Positives and False
Negatives
• At this stage, it is better to have more false
positives than false negatives.
False Negatives:
Effective interventions will
not be selected for
implementation.
As a consequence, less
likely to determine that they
are actually effective.
False Positives: Progress
monitoring will identify
interventions that are
not effective.
Role of Higher Ed in Identifying Evidence-based
Practices
• Conduct systematic reviews to identify effective
practices.

• Expand dissemination efforts.
o Specify “audience.”
 Different audiences may require different methods.
o Expand methods.
Diffusion of Innovation
Rogers, Diffusion of Innovation, 2003
• Diffusion of innovation is a social process, even more
than a technical matter.
• The adoption rate of innovation is a function of its
compatibility with the values, beliefs, and past
experiences of the individuals in the social system.
Principles for Effective Diffusion:
Improving the Odds (Rogers, 2003)
• Innovation has to solve a problem that is important
for the “client.”
• Innovation must have relative advantage over
current practice.
• It is necessary to gain support of the opinion leaders
if adoption is to reach critical mass and become selfsustaining.
• Innovation must be compatible with existing values,
experiences and needs of the community.
Principles of Effective Diffusion:
Improving the Odds
• Innovation is perceived as being simple to
understand and implement.
• Innovation can be implemented on a limited basis
prior to broad scale adoption.
• Results of the innovation are observable to others.
Q&A
Implement
Implementation: Bridging the Research-Practice
Gap
• Is identifying evidence-based interventions
sufficient to meet regulatory and ethical
requirements?
o Intent of both legal and ethical guidelines is to have
positive impact.
 Evidence-based interventions are assumed to give to give us
that chance.
• Identification is necessary but not sufficient to
assure that intervention will be effective.
Implement
What We Know
• Teachers are primary means of exposure to
interventions.
• Students will not benefit from effective practices if
they are not exposed to them.
• Data suggest that preparation programs are not
preparing trainees to use evidence-based practices.

Teacher Preparation Programs Under Scrutiny
By almost any standard, many if not most of the
nation's 1,450 schools, colleges, and departments of
education are doing a mediocre job of preparing
teachers for the realities of the 21st century
classroom.
Arne Duncan, Secretary of Education
Teacher Preparation Programs Under Scrutiny
Teacher education is the Dodge City of the education
world…it is unruly and disordered. There is no
standard approach to where and how teachers
should be prepared.
Levine, 2006
Teacher Preparation Programs Under Scrutiny
The nation’s leading educators concede that there is
presently very little empirical evidence to support
the methods used to prepare the nation’s teachers
Walsh, 2006
Is this really our choice?
Implement
Teacher Preparation Programs Under Scrutiny
• National Council on Teacher Quality reviewing all
1400+ teacher preparation programs in U.S.
o Graded on 17 standards.
 Classroom management
 Instructional Practices in reading, math, and ELL.
 Field work experience.
 Assessment practices.

Implementation: Where Good Interventions Go
to Die
• Implementation is not important unless it is done
with integrity.
• Evidence-based drug education programs are
implemented with integrity only 19% of the time.
(Hallfors & Godette, 2002)
o This may be a generous estimate.
o No reason to assume that other interventions fare better.
Implement
Why Treatment Integrity is Important?
• Kovaleski, Gickling, Morrow, & Swank (1999)
o Evaluated high vs low implementation of Instructional
Support Teams (IST).
 School-wide organizational change.
 Students benefited from IST processes only when implemented
with high fidelity.
 Implementing with low fidelity resulted in no better outcomes for
students than control group not exposed to IST processes.
 Having structures in place was not sufficient to assure high fidelity.
 Fidelity assessed one time per year.
Implement
Why Treatment Integrity is Important?
• Horner (2005)
o Effect of high fidelity vs low fidelity on office discipline
referrals.
 Schools that implemented with high fidelity had 25% fewer
office referrals for major rule violations than schools that did
not meet fidelity criterion.
 Fidelity measures taken 2 times per year.
• If we want to increase the integrity of
implementation we need a different training
model.

Challenges for Teacher Preparation Programs
• Adoption or adaptation?
o Must we implement exactly as prescribed or can we
adjust to fit local circumstances?
• Research suggests that programs are almost
always adapted.
• Presumably adapted to improve outcomes.
o Some adaptation for other reasons:
 Better fit teaching style.
 Do not like some elements of program.
Implement
Challenges for Teacher Preparation Programs
• If adapted is program still research-based?
o If teacher’s allowed to adapt then program more
acceptable.
o Teacher’s made better adaptation of reading programs if
they were well grounded in principles. (Klingner, Vaughn,
Hughes, & Arguellas, 1999).
Implement
Challenges for Teacher Preparation
• Teach principles of instruction or teach specific
methods of instruction.
o Principles of reading: 5 elements of scientifically based
instruction.
 Reading Mastery contains all elements.
o Not all schools use Reading Mastery.
 If train to Reading Mastery then may not be skilled at
implementing other reading programs.
 Principles are always expressed as part of a package.
 Not all packages created equally.
 There are more reading programs than is feasible to teach to preservice teachers.
Implement
Challenges for Teacher Preparation
• If emphasize specific curricula:
o May not be able to adapt because do not have principles
of instruction to guide decision making.
Training Methods for New Teachers
• How do we increase generalization from pre-service
to classroom?
o Clinical training Model gaining traction.
 Will require reorganization of much of training and field work
experience.
 How skills are taught at pre-service level.
 How mentors interact with trainees.
 How mentors are selected.
 How competencies of mentors are defined and evaluated.
 Length of training?
Additional Training Content: Seven Questions
Parents Should Ask and Why They Are Important
1. What is the evidence-base for this intervention?
o What is known about the effects for children like mine?
o What is known about effects in settings like this?

2. What are the other options?
•
Both Picture Exchange Communication System and
Sign Language are evidence-based for non-verbal
children with developmental disabilities.
o Usually practitioners recommend one without discussing
options.
Seven Questions Parents Should Ask and Why
They Are Important
3. Why is this intervention being recommended?
•
A good answer describes how the recommended
intervention is a good fit for a particular child.
o A less desirable answer is anything that does not describe
how it is the best match for this child.
Seven Questions Parents Should Ask and Why
They Are Important
4. What are the risks?
• All interventions have risks.
o A good answer reflects that risks have been considered
and steps taken to minimize when possible.
o Both PECS and Sign Language have risks:
 PECS requires the child always have access to the communication
system which can be difficult to transport.
 Sign language requires a community of others who sign.

They Are Important
5. Do those responsible for implementing have the
necessary training, skills, and knowledge to
implement with adequate levels of treatment
integrity?

7. How will the effectiveness of the intervention be
evaluated?
o How will the family be kept informed about effects?
o When shall we meet again to review progress?

Evaluate
Evaluating Evidence-based Interventions
Progress Monitoring
• Implementation of evidence-based intervention does
not assure success.
o Necessary to evaluate impact in local context.
 No intervention will be effective for all students.
 Cannot predict who will benefit.
o Progress monitoring is practice-based evidence about
evidence-based practices.
o Consistent with legal requirements and ethical standards.
Evaluate
Ethical Standards and Progress Monitoring
• National Association of School Psychologists
o Standard IV C 1b.
 Decision-making related to assessment and subsequent
interventions is primarily data-based.
o Standard IV 6.
 School psychologists develop interventions that are appropriate to
the presenting problems and are consistent with the data collected.
They modify or terminate the treatment plan when the data
indicate the plan is not achieving the desired goals.
Evaluate
Ethical Standards and Progress Monitoring
• Behavior Analysis Certification Board
o Standard 4.04
 The behavior analyst collects data or asks the client, clientsurrogate, or designated other to collect data needed to assess
progress within the program.
o Standard 4.05
 The behavior analyst modifies the program on the basis of data.
Evaluate
Legal Requirements for Progress Monitoring
• Fundamental to IEP process.
o Must report on same schedule that grades are reported in
general education.
• Response to Intervention is accepted as alternative
means for determining eligibility for Learning
Disability classification.
o Progress monitoring is the heart of RTI.
 All students routinely and systematically monitored to assure
adequate progress is occurring.

Progress Monitoring and Treatment Integrity
• Student data provides feedback about progress.
• If we know about adequacy of treatment integrity
then can make decisions:
o Adequacy of intervention
o Adequacy of implementation
 If implementation is inadequate then focus should be on
improving educator behavior.
 If implementation is adequate then focus should be on changing
intervention so student can succeed.
 Decisions can be made about increasing or decreasing intensity of
intervention.
