Thinking about Thinking

Metacognition: Have you ever taken a long road trip? You know where you're
beginning. You know where you want to go, but what is the best way to
get there? There are many different routes you could take. All lead to
the same destination, but some are faster and more efficient than
others. That is where metacognition comes
in. Metacognition is a buzz word heard often in educational circles
today. The term was coined by John Flavell of Stanford University in
1976, but the concept it describes has been around for more than 100
years. However, providing a precise definition for this concept has
proven tricky, even for experts in educational psychology. "Metacognition
is about being aware of and taking control of your cognitive
processes," explains George Wardlow, a professor of agricultural and
extension education. "Then, you can purposefully channel your cognitive
resources to solve problems. You could Many educational psychologists now stress
an instructional approach known as Cognitive Strategy Instruction (CSI)
as a way to develop these metacognitive skills. By using an approach
known as 'scaffolding,' teachers support, rather than explicitly direct
students as they learn, by providing learning prompts and checklists,
demonstrating proper procedure, and encouraging thinking aloud (see
Pate article). This technique encourages students to understand how they arrive at a solution, rather than just "knowing" the "right" answer. Once these thinking skills become familiar to students, they begin to exercise them unconsciously, which leads to greater efficiency in both learning and problem solving. |
Descartes said, "I think, therefore I am." A more updated version of
this quote might be something like, "I think about thinking; therefore
I think better." That is precisely what UA student Michael Pate
discovered when he began conducting research into cognitive function
and problem solving last autumn.
Pate became interested in various
techniques of learning and problem-solving during a course that he took
under agriculture professor George Wardlow on methods in agricultural
education. In it, Wardlow discussed alternatives to traditional
teaching approaches and pointed out ways in which teachers could
encourage their students to take greater control over their own
thinking and learning processes.
"I'm one of those instructors who thinks that lecture is very time efficient, but it's not necessarily very learning efficient for the students," Wardlow explains. "In most of the classes that I teach, we try to incorporate a lot of 'hands on' work, as well. I do that to model for our students that want to be teachers or industry instructors alternatives to lecture that can improve learning efficiency."
Intrigued by the ideas the class
raised, Pate applied for and received a research grant from the Bumpers
College to study the issue with Wardlow.
He then set out to put
these ideas to the test. His research focused specifically on a
technique known as Thinking Aloud Pair Problem Solving (TAPPS). TAPPS
is a technique designed to encourage metacognitive thinking (see side
bar) by ensuring that students verbalize their thoughts while working
through a task.
Pate tested students in a mechanics class as they
worked to troubleshoot and repair lawnmower engines. He divided the
class into two groups. All of the students were then given engines with
the same problem and asked to diagnose and repair them. Students in the
control group worked alone, while students in the second group worked
in pairs. In each pair, one student was assigned the job of
problem-solver, and the other was assigned to be the listener. The sole
responsibility of the listeners was to encourage their partners to
fully verbalize their thought processes while troubleshooting and
making repairs. They were told to meet even the shortest silences with
questions and prompts to keep their partners talking. Listening
partners were not allowed to offer suggestions or instructions but were
simply there as a 'sounding board' for the problem solvers.
Pate
discovered that students who used the TAPPS technique showed more than
double the success rates in repairing their equipment than did students
in the control group, and finished their repairs an average of six
minutes faster. The reason for this success, he found, lay in having
the students constantly verbalize their thoughts. By doing this, the
students were forced to become aware of their own thought processes,
which encouraged them to check themselves and correct faulty steps in
logic, thereby making the process more efficient.
"I think it
shows us another way to get our students to think in steps, to think
more clearly and to be more aware of what they are doing," explains
professor Don Johnson, one of Pate's advisers in the project. "Our goal
now is to move students from needing the listening partner, especially
since he or she isn't actually doing anything to help solve the
problem. We found that even though the control group was encouraged to
think aloud, none did. They don't use this process unless someone is
there to prompt them."
Pate and Johnson point out that the next
step is to develop successful techniques to train students in
metacognitive thought without needing to be prompted. This would
produce students with more efficient problem-solving skills, Johnson
notes.
For Pate, who plans to teach agriculture at the high school
and later college levels, the possibilities for classroom application
are intriguing.
"This represents a new way of teaching students how to think," he said. "They are going to face all kinds of problems on a daily basis both in school and outside of school, and this technique is effective on far more than just lawnmower engines."
