Why It’s So Hard to Replicate Successful Programs
(Originally titled
“Trust But Verify”)
“School improvement programs that work in some places
don’t work in others,” say David Berliner and Gene Glass (Arizona State
University) in this Educational Leadership
article. Why? “Education… is a complex, intricate endeavor that entails inputs
we can’t control (for instance, family wealth, parents’ education, community
support, and special needs of children); variables we can’t easily identify or
measure (such as competing school and district initiatives, classroom culture,
peer influence, teacher beliefs, and principal leadership); and outputs we can
neither predict nor easily measure (such as resilience, grit, practical
intelligence, social intelligence, and creativity). No wonder we can’t find a
silver bullet for school problems, say Berliner and Glass – education is more
complex than rocket science!
In addition to the complexity of schools, three other
problems make it hard to transplant seemingly successful programs:
• The fine print in
research findings – How strong were the original results? Under what
conditions did the program work? Were there any negative effects?
• The problem of
replicability – It’s much more difficult to do “gold-standard” replication
studies in education than in medicine; fewer than 1 percent of educational
research studies have been replicated.
• The problem of
fading effects – A program that was successful in one situation may not
work in another because teachers, students, school culture, and assessment
instruments are different. And bringing a program to scale across many schools
poses even bigger challenges.
So what are school leaders to do? Read research very
carefully, be cautious applying it, do small trials before going to scale, and
always pay close attention to the local situation, say Berliner and Glass. They
also offer some general lessons:
-
Get
teachers on board. “Not much works well if teachers have things imposed on them
that they don’t believe in,” say the authors.
-
Less is
more. It’s a mistake to implement several new programs and ideas at once.
-
Put new
programs through a formative evaluation and if they are successful, use the
data to fine-tune them.
In a sidebar, Berliner
and Glass mention several of their “pet ideas” that they believe may travel well:
-
Recognize
that teachers often work in teams.
-
“Make
sure the evaluation system has no consequences for teachers associated with
student test scores,” say the authors, “but do include multiple classroom
observations and an evaluation of classroom artifacts – tests, papers,
projects, and the like.”
-
Make
sure that no school day for students starts earlier than 8:30 a.m.
-
Provide
libraries staffed with librarians and counseling offices staffed with enough
counselors so they can get to know students personally.
-
Get
students reading more and be very skeptical of packaged programs that claim to
improve reading.
-
Eliminate
tracking in grades K-6.
-
Eliminate
retention in all grades.
