Advancing Educational Technology
EDIT 9990
Goals



Critique the stateof-the-art of
educational research.
Describe applications of
“design-based research.”
Encourage new thinking
about why and how we do
research.
Improving the
quality of
teaching and
learning
through
educational
research is
critical to our
survival.

The lack of
scientific
literacy is
appalling in
even the
most
developed
countries.
Bad News
Most educational
research has
little impact on
practitioners and
yields few
discernable
benefits.
Oh...no!
The Failure of
Educational Research
– Vast resources going into
education research are
wasted.
– They [educational
researchers] employ weak
research methods, write
turgid prose, and issue
contradictory findings.
The Failure of
Educational Research
– Too much useless work is
done under the banner of
qualitative research.
– Qualitative research….
[yields] ….little that can be
generalized beyond the
classrooms in which it is
conducted.

improvement in
education over the
last 30 years, despite
a 90 percent increase
in real public spending
per pupil.”
 Promotes randomized
controlled trials as
used in medical

What Works
Clearinghouse
The What Works Clearinghouse
(WWC) has been established by the
U.S. Department of Education’s
Institute of Education Sciences to
provide educators, policymakers,
researchers, and the public with a
central and trusted source of
scientific evidence of what works in
education.
Slavin’s 5 Questions for Valid
Educational Research
Is there a control group?
 Are the control and
experimental groups
assigned randomly?
 If a matched study, are the
groups extremely similar?
 Is the sample size large
enough?
 Are the results statistically
significant?

Robert Slavin
“What Works” Position
“Once we have dozens or
hundreds of randomized
or carefully matched
experiments going on
each year on all aspects
of educational practice,
we will begin to make
steady, irreversible
progress.”
 NCLB funds “scientifically
based research.”

Robert Slavin
“It Won’t Work” Position
Double blind experiments
impossible in education
 Implementation variance
reduces treatment
differences
 Causal agents are underspecified in education
 Goals, beliefs, and
intentions of students and
teacher affect treatments

David R. Olson
Medical and health knowledge
is rarely applied sufficiently.
Another “It Won’t Work” Position



The What Works Clearinghouse
(WWC) standards “ignore the
critical realities about social,
organizational, and policy
environments in which
educational programs and
interventions reside.”
Advocates “decision-oriented”
evaluation research over
“conclusion-oriented” academic
research.
Recommends extended-term
mixed-method (ETMM) designs
as a viable alternative.
Madhabi Chatterji
American Evaluation Association
The priority given to randomized controlled
trials “manifests fundamental
misunderstandings about 1) the types of
studies capable of determining causality, 2)
the methods capable of achieving scientific
rigor, and 3) the types of studies that support
policy and program decisions. We would like
to help avoid the political, ethical, and
financial disaster that could well attend
implementation of the proposed priority.”
Randomized controlled
trials are the only way
we’ll ever be able to prove
“what works” in education!
Randomized controlled
trials promotes
pseudoscience and will
limit effective change!
Educational
researchers
have failed
to make a
clear appeal
to the public
for their
support.
People
learn
when
…..
Ellen Lageman argues
that educational
researchers, in a
misguided effort to be
“scientific,” have
turned away from the
pragmatic vision of
John Dewey.
 She attacks the
excessive emphasis
on quantitative
measurement.

Kieran Egan argues
that progressive ideas
from Herbert Spencer,
John Dewey, and Jean
Piaget are responsible
for the “general
ineffectiveness” of our
schools.
 He also assails the
notion that education
can be improved
through research as
traditionally conceived.

Thomas Kuhn
The Structure of Scientific Revolutions
"I'm not sure that there can now be such a
thing as really productive educational
research. It is not clear that one yet has
the conceptual research categories,
research tools, and properly selected
problems that will lead to increased
understanding of the educational process.
There is a general assumption that if
you've got a big problem, the way to solve
it is by the application of science. All you
have to do is call on the right people and
put enough money in and in a matter of a
few years, you will have it. But it doesn't
work that way, and it never will."
Complexity of Interactions
We cannot store up
generalizations and
constructs for
ultimate assembly
into a network.
 When we give
proper weight to
local conditions, any
generalization is a
working hypothesis,
not a conclusion.

Lee Cronbach
Learning Styles
“Research into learning
styles can, in the main, be
characterised as smallscale, non-cumulative,
uncritical and inwardlooking. It has been
carried out largely by
cognitive and educational
psychologists, and by
researchers in business
schools and has not
benefited from much
interdisciplinary research.”

Educational technology researchers
are not doing much better than other
educational researchers.
NCLB Requirements
"every student is
technologically literate
by the time the student
finishes the eighth
grade," and
 "that technology will be
fully integrated into the
curricula and
instruction of the
schools by December
31, 2006."

Abundant technology
has not led to
extensive use of
computers for
“tradition-altering
classroom
instruction.”
 The small percentage
of computer-using
instructors only use it
to maintain existing
classroom practices.

Teachers have legitimate concerns.
Is it simple enough for
me to learn quickly?
 It it versatile?
 Will it motivate students?
 Is it aligned with skills I’m
expected to teach.
 Is it reliable?
 It it breaks, who will
help?
 Will it weaken my
classroom authority?

Ed. Tech Research Reality
Isolated researchers conduct
individual studies rarely linked to
a research agenda or concerned
with any relationship to practice.
 Studies are presented at
conferences attended by other
researchers and published in
journals few people read.
 Occasional literature reviews
and meta-analyses are
published.

Ed. Tech Research Reality
Many educational technology
studies claim to have predictive
goals (testing theories) and use
quasi-experimental designs with
quantitative measures.
 Research reviewers usually
must reject 75 percent or more
of the published studies to find
the few worthy of further review
or inclusion in meta-analyses.

Ed. Tech Research Reality
Dillon & Gabbard’s 1998 literature
review of “Hypermedia as an
Educational Technology” highlights
problems with IT research.
 Major conclusion: “Clearly, the
benefits gained from the use of
hypermedia technology in learning
scenarios appear to be very limited
and not in keeping with the generally
euphoric reaction to this technology
in the professional arena.”

Ed. Tech Research Reality
Fabos & Young 1999 literature review
of “Telecommunications in the
Classroom: Rhetoric Versus Reality” is
another bad sign.
 Major conclusion: “…many
of the expected benefits of
telecommunications
[enhancing writing,
multicultural awareness,
and economic possibilities]
are inconclusive, optimistic,
and even contradictory.”

Sir John Daniel - UNESCO
… the futile tradition of comparing
test performances of students
using new learning technologies
with those who study in more
conventional ways…is a pointless
endeavor because any teaching
and learning system, old or new,
is a complex reality. Comparing
the impact of changes to small
parts of the system is unlikely to
reveal much effect and indeed,
“no significant difference” is the
usual result of such research.
Chewing Gum More Effective than
Interactive Multimedia CD-ROM
Dr. Ken Allen at NYU
wanted to compare CDROM with lectures
 Wrigley’s wanted to fund
chewing gum study
 Combined study
 Gum chewers = BAbstainers = C+
 CD-ROM no better

Media comparison studies are akin to
comparing copper bracelets with
voodoo dolls as medical cures.
Experimental approaches to
educational technology research
won’t work in the way that they do
in medical research!

Good News
There are new strategies
for conducting “designbased research” that can
improve our research
so that it can
become
a socially
responsible
enterprise.
Thank
goodness!
Educational researchers often fail
to distinguish between research
goals and methods.
Six Ed. Tech research goals:
Theoretical
Predictive
Interpretivist
Postmodern
Design/Development
Action/Evaluation
Theoretical Goals
Focus on explaining
phenomena through
logical analysis and
synthesis of
principles and results
from other studies
 EXAMPLE: Gagne’s
theory of the
conditions of learning

Predictive Goals
Focus on determining
how education works
by testing hypotheses
related to theories of
learning, teaching,
performance, etc.
 EXAMPLE:
cooperative learning
and control studies by
Hooper, Temiyakarn,
and Williams

Simon Hooper
Interpretivist Goals
Focus on determining
how education works by
describing and
interpreting phenomena
related to learning,
teaching, performance,
etc.
 EXAMPLE: Delia
Neuman’s observations of
disabled children using
commercial software

Delia Neuman
Postmodern Goals


Focus on examining the
assumptions underlying
educational programs with
the goal of revealing
hidden agendas and
empowering
disenfranchised minorities
EXAMPLE: Ann
DeVaney’s analysis of IT in
relation to race, gender,
and power
Design/Development Goals


Focus on dual
objectives of
developing creative
approaches to solving
problems and
constructing reusable
design principles
EXAMPLE: Sasha
Barab’s “Quest Atlantis”
project and “Learning
Engagement Theory”
Action/Evaluation Goals
Focus on describing,
improving, or estimating
the effectiveness and
worth of a particular
program
 EXAMPLE: Hill and
Reeves four-year
evaluation of ubiquitous
computing initiative.

Methods should not be selected until
goals & research questions are clear:
 Quantitative
 Qualitative
 Critical
Theory
 Historical
 Literature
Review
 Mixed-methods
So what
does
designbased
research
look like in
the real
world?
Design-Based Research Collective
Goals of designing learning environments
and theories are intertwined
 Development and research occur in
continuous cycles
 Research on designs leads to sharable
theories relevant to practitioners
 Research must account for how designs
function in authentic settings
 Development of accounts relies on methods
that connect actions to outcomes

Design-Based Research Strategies
Define a pedagogical outcome and create
learning environments that address it.
 Emphasize content and
pedagogy rather than
technology.
 Give special attention to
supporting human
interactions.
 Modify learning
environments until
outcome is reached.

methods in their
student teaching
experience and
eventual practice.
Learning Environment Design
 Identified
the critical
characteristics of a
situated learning
model.
 Developed an
interactive multimedia
learning environment
based on those
characteristics.
Situated Learning Model
Herrington 1997





Provide an authentic context
reflecting the way the knowledge
will be used in real-life
Provide authentic activities
Provide access to expert
performances and the
modeling of processes
Provide multiple roles
and perspectives
Support collaborative
construction of knowledge
Situated Learning Model
Herrington 1997
Promote reflection to enable
abstractions to be formed
 Promote articulation to enable
tacit knowledge to be made
explicit
 Provide coaching and scaffolding
at critical times
 Provide for integrated
assessment of learning within
the tasks.

Mixed Methods Design
Videotaped
preservice teachers
using program
 Interviewed teachers
and their supervisors
in schools during
student teaching
practicum
 Logged usage data

Findings

Problem Solved:
– Novice teachers acquired
advanced knowledge while
engaging in higher order
thinking
– New knowledge and skills
applied in practicum

What
challenges do
we face in
adopting
design-based
research
approaches?
Design-Based Research Challenges
–Sampling bias
–Response bias
–Researcher bias
–Overwhelming data
–Confounded variables
–Dissemination
–Scaling up
Ann Brown
Design-Based Research Collective
We suggest that the
value of designbased research
should be
measured by its
ability to improve
educational
practice.
Because we are a
design profession
(not a discipline),
educational
technologists should
pursue designbased research that
integrates the desire
to solve problems
with the search for
knowledge.
“The status of research
deemed educational
would have to be
judged, first in terms of
its disciplined quality
and secondly in terms
of its impact. Poor
discipline is no
discipline. And
excellent research
without impact is not
educational.”
- Charles W. Desforges (2000)
