Applying--What is the best way to apply heuristic techniques to a
difficult problem or topic? Should we go into it with a predetermined plan or
allow full student autonomy?
Heuristics are general
problem-solving strategies that may be applied to a variety of problems, but
they do not guarantee a successful outcome (Ormrod). As such, heuristics may be
more applicable to ill-defined problems, i.e., unclear problems with missing
information or more than one answer. Ormrod gives the example of deforestation,
but I will use the issue of damming to illustrate how to use a heuristic
strategy to tackle an ill-defined problem.
In Loudon, County, Tellico Dam has
generated a firestorm of opinions over the last three decades. For opponents of
the dam, the problem to be solved was how to halt dam construction and stop
flooding of the area. Opponents took a number of approaches. Some made a moral
argument against the uprooting of families and destruction of Native American
settlements and burial grounds. Others made economic arguments to counter the
dam advocates. Opponents claimed the dam would not generate enough energy to
justify its existence. They also pointed to how capital could be brought in
through developing a tourist industry centered on trout fishing, mountain
scenery, and local, Native American culture. Finally, environmentalists pointed
to the irreparable damage the dam would cause both to the land and quality of
the water. This last approach stalled the dam the longest as an endangered
species was found in the waters; though, it was ultimately, successfully
transplanted to another habitat. With respect to this issue, a variety of
approaches were applied to the problem of closing the dam.
Students should learn how to apply
heuristics to complex, authentic problems such as the one listed above. We
cannot, especially for young students, allow for full autonomy in the heuristic
process. By this, I do not mean we do all of the work for the student. Rather,
we must directly instruct students on how to apply heuristics and scaffold them
to their desired end. With enough practice, and if they demonstrate a firm
grasp on developing processes to solve complex problems, we may allow for
increasing student autonomy. However, we must always be there to offer advice
for students and get them back on track if they ever become distracted.
Create--Construct a project that allows
students security that to take risks and at the same time can be evaluated.
Before
constructing my problem, I acknowledge that working memory puts a limit on how
much students can process at one time. I also realize that complex problems
require significant metacognition (Ormrod). To help students with the project,
I will explicitly state the goal(s) and procedures, break down the problem into
subcategories for the students, and encourage self-monitoring. All of the above
are effective strategies used by efficient problem solvers, according to
Ormrod. I will also make sure students are mastering the material before they
begin the project, and I will give students enough time to ensure they can be
creative and think critically.
My
project will require students to pick a historical figure and write a
biography. Students will have to research and reference materials outside of
the textbook to relate their characters’ experiences with what we are covering
in class. For instance, students might relate how Frederick Douglass’ experiences
with slavery and reform work might inform his attitude toward reconstruction. For
this project, I will give students enough time to do their initial writing. I
will allow them to make mistakes, receive my feedback, and correct their work.
I will set aside time for small group discussion of the activity, and I will
only grade after the third or so submission.
