This interview with Don Evans, Director
of the Center for Research on Education in Science, Math,
Engineering, and Technology at Arizona State University,
took place on the campus of Arizona State University on May
14, 2001.
Susan Ledlow: . . . I’m here
today with Don Evans, who is the director of the
Center for Research on Education,
Science, Math, Engineering and Technology
and the Director of the
Foundation Coalition Engineering
Project here at ASU. Don, I’d
like to start by asking you a little bit about your
background in engineering.
Don Evans: Well, I’ve been in
engineering for a long time—about thirty-five years. When I
entered into undergraduate school, I thought I wanted to go
into industry and sometime own my own business. When I got
my bachelor’s degree, I decided I didn’t know enough about
anything in-depth. I knew a lot of things about many
fields, but not much in-depth. I went to graduate school,
and that is when I became interested in teaching. I did
work for General Motors when I was in the undergraduate
program, and then I came straight . . . to ASU. That was a
long time ago, and I’ve been in engineering since that
time. I’ve been a department chair or interim department
chair and now the director of a Center.
Ledlow: How did you get
interested in engineering education or science, math and
technology education?
Evans: . . . It’s a long story
that I can’t tell totally here. But, briefly, about the
mid-eighties, [university staff] came to me and said . . .
“You’re using [computers] more than anyone else on the
faculty. We need to revise the freshman program to keep it
modern. We want to get some computer centers. Would you do
that?” I said, “Absolutely not!” I was not interested in
teaching freshman. They worked on me for about six months
or so . . . and finally I decided to give it a try, . . .
and I’ve been doing it ever since. That is in the education
side. Ever since, my interest has deepened. When I
participated in things like the
ASEE and
the
FIE, I
realized there were a lot of things that we really did not
know about how people learned (that we were using anyway)
and started doing some research and investigations into how
that might be done.
Ledlow: The
Foundation Coalition
stresses active or cooperative learning as an important part
of its curriculum. What are some of the driving forces that
are making you promote cooperative and active learning in
engineering education?
Evans: Before the coalition
started we had done several classes using cooperative
learning. When the schools that ultimately became the
Foundation Coalition got together, we decided there were
certain student attributes we wanted to address. To do that
. . . there were really three main approaches. One was to
address the interfaces between students and between students
and faculty. That’s where the cooperative, the active
learning strategies, and the teaming come in. The next was
[the] use of technology. At that time, we were thinking
about power tools: MAT Lab and MAYPOL— things of that sort.
The third was integration of materials. . . integration of
topics and subjects so there was a uniform approach to the
materials in engineering—so that subjects didn’t seem to
stand alone, disconnected from anything else. So, these
were the three main thrusts . . . that we thought would
generate the student attributes we wanted to see.
There was also an assessment component
. . . to check and see if we were doing any good or not.
Because we had experience with active and cooperative
learning, we became the initial drivers on that part of the
coalition. I myself got involved in [cooperative learning]
after attending a workshop that
Karl Smith
ran. I decided there might be something to this, so I tried
it in my classes and it seemed to work. I had an
opportunity to teach a summer class . . . . I had never
done it before, and I had no interest in teaching a summer
class at the time. But it needed someone, since the person
who was going to teach it couldn’t. They asked me and
worked on me for another few weeks, so I decided I would try
it, . . . and I would use cooperative learning. We did a
class in dynamics. . . in five weeks. I think I would
rather turn over a dynamics problem to that class than any
other class I’ve had up to that time. They knew more about
dynamics [from using active, cooperative learning] than they
had with me telling them to do things. That is really what
got me started, and I have used [cooperative learning] ever
since.
Ledlow: The
Foundation Coalition
is not the only group of universities looking at [learning
in engineering education]. At a national level, what is the
push . . . to improve science, math, engineering, and
technology education?
Evans: There are several things
going on. One: U.S. students are not doing very well
compared to other countries. We could argue about how far
we are behind everybody else, but it turns out that our
students really don’t learn the things that we think we are
teaching. So, there is a big movement, especially in
science and mathematics education, to do what is called
inquiry-based learning. This lets the student generate
the question, become curious about things . . . [and] lets
them deal with some topic before [a teacher] does a lecture
on it. Part of that [learning method] is to get the
students to work together and talk to one another. The
teacher [is] just a monitor of that—not the leader of it—to
guide them through that discovery period and make sure that
information is stored away in the correct way, so it is
usable. That’s continuing on up through colleges and
universities, I think. It’s going slowly, because
[teaching] is different for college faculty. We have time
problems and limitations . . . . We have a lot of subject
matter that has to be covered, [and these] are deterrents to
doing [cooperative learning]. But one has to stop and ask,
“Do you want [students] to learn the material or just
memorize it up to the next exam?” So, I think that
is driving the use of active learning strategies to improve
the quality of the learning. There is also another reason.
If we are successful in converting all of K-12 to this type
of learning philosophy, will the students want to come to
university, to sit in our classes, and listen to a talking
head? This is another big problem we have to face up to.
One of these days we will have to change, or we are going to
lose those students.
Ledlow: How did the ABET 2000 [Accreditation
Board for Engineering and Technology]
Criteria fit in with this movement towards active,
cooperative learning and inquiry-based learning?
Evans: The ABET 2000 Criteria
learning came out with about eleven different student
outcomes. One of the criteria is that students should be
able to work in multi-disciplinary teams. Most of us over
the years have just put the students together in teams of
three or four, or whatever, and said, “Go at it!”—sometimes
with disastrous results. Sometimes it worked, sometimes it
didn’t. What we found over the years, as we’ve been in
existence as a coalition, [is that] if we give students some
training in interpersonal skills and training in . . . how
to run the process as a team, the success rate is much
higher. It’s not one hundred percent. You do still have
dysfunctional teams and have to learn how to deal with
those, but the success rate over all is much better and the
quality of work is much better. So, we are all struggling
to meet the criteria imposed by the ABET, the EC [Evaluation
Criteria] 2000. Somehow, we are going to have to deal with
that problem, or that challenge, of working with
multi-disciplinary teams.
Ledlow: Let’s talk about some
of those challenges a little more specifically. I know
individual faculty face challenges when they are trying to
change their teaching [methods]. From your perspective as an
administrator, what are some of the challenges [that arise]
. . . at the department level or at the school level when
you are trying to make these changes?
Evans: One of them is . . .
that we impose an assessment process on essentially all of
our classes. Students fill out instructor evaluation
forms. During the times when you are trying to make a
transition, you are not always sure what to do. . . .
You’re going to make some mistakes. If we continue to
assess everything that we do, even transitions to new
things, we are going to run into problems; because,
occasionally, students may not like something that you have
tried. That dislike shows up in the ratings, and somebody
gets penalized for it. During those transition periods, we
have to back down and take a different view about assessment
. . . and say this was a transition period. We’re finding
throughout the Coalition and throughout several other
projects that are going on at the Center [Center
for Research on Education in Science, Math, Engineering, and
Technology] that it takes three to five
years for that faculty member to make that transition . . .
from lecturing as an expert in class to one who can guide
the students through their learning—to judge whether
[students] are learning or not, listen to their dialogue,
and make sure they store this information away in ways that
it is useful and correct.
Ledlow: What advice would you
give a department or a school if they want to change their
curriculum to be more inquiry based?
Evans: Well, I think the big
change is to change the evaluation process during those
transition periods. Also, [they need] to reward faculty for
doing it. . . .
The Carnegie Foundation for the
Advancement of Teaching
makes two distinctions. They talk about “scholarly
teaching” and “the scholarship of teaching.” Everyone
should be using scholarly teaching. That is, [faculty
should be] using the best teaching practices in the
classroom, and they should be trying things like cooperative
learning. They should be doing things like using teams,
perhaps. Not all classes need to use teams, but that is
something that should be done in several places in a
continuous way throughout the curriculum. And [there is
also] the use of technology. All those things should be
used to do teaching in a scholarly way, an informed way:
“What do we know from the research base and how do we use
that?”
The other is the scholarship of
teaching, which means that, as an instructor, I’m going to
put that material out . . . for critique by others and for
use by others . . . like we do in the research side. We do
a project in research and we publish those results for
whoever wants to use them or for criticism. We don’t do
that in teaching. I think, if we were to approach teaching
the way we do research, we wouldn’t have the dilemmas that
we are in today. I think we would have a much better
learning environment.
Ledlow: . . . Why are you,
personally, a proponent of active and cooperative learning?
Evans: I think the big reason is
that I have used it in my class, and I have seen a
difference in my students. You can see the light bulbs go
on in their heads when they get it, after they have
discussed it, and as they have tried to explain it to
others. I’d . . . very seldom seen that before . . . except
for some very bright students who will do this anyway. But
the majority of the students really don’t quite get it. . .
. [Sometimes] they will get it later when they are doing
their homework, but you are never sure what process they’ve
gone through in the solution of these problems and
challenges you’ve sent out as out-of-class work. With
active strategies, you can see that [process] happening in
the classroom. You know if they are thinking correctly
about these ideas. You know how they are interpreting them,
because they have had to articulate their thoughts on what
they are doing. And you have been able to monitor some of
that (not all of it) because some of it is going on in the
classroom. You can go around to different teams and do spot
checks to see that everybody is on track. I think it helps
everybody overall.
The first time I used [cooperative
learning], I asked a couple of questions and gave them time
to work on something. I picked a random person from each
team to go to the board and draw a free-bodied diagram on
the board. I saw eight free-bodied diagrams, because there
were eight teams and each one had a free-bodied diagram.
What I had been used to was telling [students] the best way,
in my view, to work that problem. Now I see eight diagrams
the way [students] thought to work the problem. Now I have
a chance of discussing each of those [ways]. I never had
that before. So, that’s the real reason I’ve done it. I’ve
seen an improvement in class; Certainly, [I’ve seen] an
increase in interest and the involvement of the students.
Ledlow: Thank you.
