While the law requires teachers to use evidence-based
practices in their classrooms, the field has not yet determined
criteria for evidence based practice nor whether special education
has a solid foundation of evidence-based practices. Also, those
teaching strategies that have been researched are difficult for
teachers to access.
On the topic of evidence-based practice, there
is one point of agreement: The law says teachers must use evidence-based
teaching practices (EBPs) to ensure their students receive the highest
quality instruction. From there the discussion splinters into a
myriad of issues, ranging from how much evidence is needed to give
a practice credibility to acceptable research methods to the lack—or
abundance--of research on students with special needs. Then there
are the questions concerning EBPs in the classroom: how do teachers
access EBPs, do teachers use the methods correctly, and how can
teachers meld EBPs and the craft of teaching.
While these issues may not be resolved they are
important, because EBP and high quality teaching go hand-in hand.
Teaching techniques that have been proven to be effective can help
students make more progress in shorter amounts of time. When these
practices are added to teachers’ professional skills and knowledge
of their students, you have a winning combination when it comes
to teaching and learning.
While this seems pretty straightforward, the difficulty
lies in making the concept a reality. Special education, and education
in general, is struggling to define and standardize EBPs. The next
hurdle to be overcome is getting EBPs to the teachers. And finally,
teachers need to have the time, tools, and resources to implement
the practices.
Evidence-Based Practice—Where
We Are
The Research
The very concept of EBP raises
a host of unresolved questions. The foremost is what type of information
counts as evidence for good practice. The Department of Education’s
Institute for Education Sciences has stated that the randomized
control trial (RCT) is critical to establishing evidence of an instructional
technique’s effectiveness. These are studies that measure the effectiveness
of a strategy by randomly assigning students to a control or intervention
group.
While special education researchers agree
that RCT is a valid and important measure, many say it is only one
method that should be considered for students with disabilities.
Because of the complexity of disability population, other types
of research can offer valuable information about the effectiveness
of a teaching strategy.
“In special education, many issues are complex:
the type of disability, the setting the student is in, the content
we teach, the available supports,” says Rachelle Bruno, professor
at Northern Kentucky University and chairperson of CEC’s Evidence-Based
Practice Workgroup. “Large scale studies don’t take that into account.”
Therefore, special educators say we need
to also consider other types of research. Experimental or single
or group design research, in particular, can yield valuable information
on the effectiveness of a teaching strategy. In single or group
design research, an individual or set of individuals participate
in a study that measures their performance before and after a strategy
is implemented. Other research methods, though they may not have
as direct a relationship, can still yield important information
on effective instructional strategies for students with disabilities.
These include research methods such as correlational research, which
shows an association between two factors, such as class attendance
and grades, and qualitative research, which describes a phenomena
and involves techniques such as observation, oral histories, interviews,
and content analysis.
A second issue involves the lack of standards
for EBPs. While one researcher may decide a teaching strategy has
enough evidence to give it high marks, another researcher, using
different criteria, may give the research a lower rating.
Some also question whether enough research
has been done on students with disabilities. One concern is that
much educational research, particularly large-scale studies, has
not included students with special needs. However, others say special
education is ahead of the game. Because special education has conducted
20-30 years of research, we have a solid, empirically supported
series of practices in assessment and instruction that special education
teachers can rely on, according to Doug Fuchs, professor at Vanderbilt
University and CEC’s 2004 Outstanding Research Award Recipient.
“Special education researchers, in partnership
with practitioners, have been involved in developing evidence-based
practice long before No Child Left Behind,” says Fuchs. “As a result,
there is a considerably strong and impressive literature base on
instructional practices and behavior support for students with disabilities.”
Evidence-Based Practice in the Classroom
Even with the above issues resolved, some roadblocks still deter
teachers from using EBP. EBP is not easily accessible to many teachers,
particularly after they have completed their formal preparation
program. Current sources for EBPs include a few books; professional
development events such as CEC’s convention and division and state/provincial
conferences; educational journals such as TEC, EC, and CEC’s division
journals; and a small number of Web sites.
But having the information available is
only part of the solution. It needs to be in a format teachers can
grasp quickly and easily, and that is rare. Teachers say they need
information that tells what the practice is, the students for whom
it is effective, how to implement the practice, and how the practice
is rated (good, okay, don’t go there). (The Practice Alerts produced
by CEC’s Division for Research and Division for Learning Disabilities
and the practices on CEC’s Web site best meet these criteria).
“The field is at a point where it is elaborating
and identifying practices that have evidence of being effective,”
says Sam Odom, Otting Professor of Special Education at Indiana
University. “There may be a lag between needing to use it (the research)
now and the research being accumulated and available.”
Another issue that arises with EBP is that
of fidelity, or whether teachers correctly implement the strategy.
Some fear that EBPs aren’t effective if teachers don’t use the procedures
as they are designed. That can be difficult for teachers to do if
their only contact with a strategy is by reading. Though training,
which can be problematic for teachers to attend, gives teachers
more insight into a strategy, some teachers say even that isn’t
enough. For teachers to use EBPs with fidelity, they need to have
the support of an expert in the strategy as they implement it in
their classes, says Connie Miller, CEC’s 2006 Clarissa Hug Teacher
of the Year.
“That is the way you get the strategy going
in daily instruction and you have the materials to do so,” she explains.
“You must make it real practical for teachers.”
A final issue is how teachers are to wed
EBPs and the craft of teaching. There often comes a point when teachers
modify the strategy for one or all of their students. While that
may compromise the integrity of the strategy, many researchers do
not find it surprising, especially in special education. After all,
the basis of what we do in special education is to individualize
according to students’ needs, says Odom. He recommends that teachers
begin using a strategy exactly as it is proposed. As the teacher
gains experience and collects information about the students’ performance,
he or she may make modifications where needed.

What Teachers Say About Evidence-Based
Practice Special education teachers
believe in EBP. They want it, look for it, and use it. In fact, special
education teachers are always searching for new ways to help their
students succeed. They look for conferences that present research-proven
techniques. Or, they find a strategy that looks interesting, and then
delve deeper to find the research on it. “Every
good teacher uses evidence-based practice,” says Jane Humphrey,
CEC’s 2004 Clarissa Hug Teacher of the Year. “….You are preparing
your students for something further on…. My job is to help my students
get there, and evidence-based practice helps me get them there.”
Though teachers value EBPs, they differ
in the amount of evidence they require before trying a particular
technique. Some prefer to use strategies that have a large amount
of research behind them, sometimes as much as 10 years’ worth. Even
then, the teachers may not give the strategy a go. Instead, they
will augment the written literature with other teachers’ recommendations
and insights on a researched strategy’s effectiveness. This also
allows teachers to prepare for any pitfalls or negative effects
on particular students that may occur with a new teaching technique.
“I want to see evidence, because these are
my babies,” says Carol Dinsdale, CEC’s 2005 Clarissa Hug Teacher
of the Year. “I won’t try a strategy with them if I don’t see some
evidence that it will work.… I won’t jump into a new strategy”
Others will try an intriguing technique
that sounds promising even if it has little research evidence to
back it up. They are unwilling to wait for several years for the
research to be verified.
“Who are we to say that because a technique
hasn’t been proven with a huge population that it isn’t successful?”
says Miller, who implemented a video-teaching technique though it
didn’t have a lot of evidence behind it with great success. “We
can’t be closed-minded.”
Whether they require a lot or a little research,
teachers use research-based strategies to improve their students’
success. When Miller wants to try a strategy that is new but shows
promise, she gets permission from her students’ parents. She tells
them she learned of this new strategy, that she’d like to try it,
and how she will implement it. Dinsdale even informs her grades
2-3 students with behavior disorders that the strategies they are
using are research-based. While she now has to contend with questions
such as “Where did you find this information?” and “Is it based
on research?” she says it gives her students more confidence in
the strategy and they buy in to using it. Finally, the research
often validates the work the teachers are already doing.
However, many special education teachers
say they rarely stick to the letter of an EBP. Rather, once they
learn the core principles of the research, they usually tweak the
strategies to fit their students. For instance, the research for
the video strategy Miller used was based on teaching functional
skills. She modified the strategies to teach her students to read.
As important as EBPs are to special education
teachers, most said getting access to it is difficult. While many
teachers read research journals, they find the articles difficult
to translate into usable terms, especially given their limited time.
Therefore some teachers rely on their state departments and districts,
who have textbook adoption committees to ensure that materials and
texts chosen for classroom use are evidence-based, according to
Matty Rodriguez-Walling, CEC’s 1994 Clarissa Hug Teacher of the
Year. Additionally, because of time and budget cuts, it is often
difficult for teachers to attend professional development events,
particularly if they pertain only to special education.
One way to enable teachers to access to
EBPs is for schools and districts to support them. In her school,
action research is part of teachers’ evaluations, says Dinsdale.
That is, the teachers take an idea that was researched and use it
in their classes for improved scores and behavior. Additionally,
the school hosts a “Professional Sharing” once a month, at which
faculty members present new, researched teaching strategies. They
share whether the strategy worked in their class, if they modified
it, and its results. The school also made a professional library
for teachers to find books with researched instructional strategies.
Another effective method of giving teachers
access to research is to involve them in it. Not only do the teachers
learn the correct way to implement the strategy, they also get the
supports, materials, and someone to talk to about the strategy.
“Give teachers the opportunity to participate
in research, and news of the strategy will travel by word of mouth,”
says Miller.

What CEC Is Doing on Evidence-Based
Practice CEC is taking a leading role
in defining and presenting EBP for the field. CEC’s Professional Standards
& Practice Committee has developed a comprehensive proposal for EBP.
The proposal will select appropriate criteria to identify EBPs and
develop a process by which CEC would identify EBPs. Additionally,
CEC’s Division for Research has made recommendations to the Institute
for Educational Sciences. CEC-DR said IES should promote research
for children ages birth – 21, not just school-age children; research
should include social and transition skills; and IES should coordinate
with the Office of Special Education Programs regarding the implementation
of the Individuals with Disabilities Education Act, among others.
