The explosion of educational
technologies in the past decade or so has led everyone to wonder whether the
landscape of higher education teaching and learning will be razed and
reconstructed in some new formation. But whatever changes might occur to the learning
environments we construct for our students, the fundamental principles
according to which human beings learn complex new skills and information will
not likely undergo a massive transformation anytime soon. Fortunately, we seem
to be in the midst of a flowering of new research and ideas from the learning
sciences that can help ensure that whatever type of approach we take to the
classroom—from traditional lecture to flipped classes—can help maximize student
learning in our courses.
One fascinating implication of this
growing body of research for me has been a greater awareness of the edges of a
traditional class. Environmental biologists have dubbed landscapes that sit on
the edge of two different ecosystems (such as a forest and a grasslands
environment) an ecotone. These spaces are known for having rich
biological diversity, because they can support creatures from both sides of the
ecotone, and encourage mixing between the bordering zones. The especially rich
nature of the ecotone has also become known as the “edge effect.”
The ecotone of a traditional college
class would be the first and last few minutes of the class session, when
students are walking in the door from their busy lives outside of the
classroom—coming from meals with friends, from exercise or sports activities,
from socializing either in person or through their phones—and entering this
more formal learning space. Too often these first and last minutes of class are
frittered away with administrative details, hurried reminders about due dates
or admonitions about upcoming assignments. But what if we saw those ecotones of
the classroom exactly as we saw them in the natural world—as especially rich
and fertile periods, ones in which we can begin and end the process of
promoting deep learning for our students?
Two key cognitive activities seem to
me especially promising in terms of their ability to maximize student learning
in the ecotones of higher education: predicting and retrieving.
Predicting. In a 2009 article in the Journal of Experimental
Psychology, Kornell, Hays, and Bjork describe a series of experiments in
which they gave participants test questions on subject matter before they had
the opportunity to study or learn it correctly. One of their interests was
determining whether incorrect answers on a pre-test—which are likely to happen
when the subjects have not yet been exposed to the material—would create
further difficulties for the learner down the line. In other words, if learners
give a wrong answer on a pre-test, will that answer stick in their heads and
make them more likely to repeat it on subsequent exams?
Not only did the researchers
discover that wrong answers on pre-tests do not interfere with subsequent
learning—they also discovered that asking learners questions about subject
matter before they learned it actually improved their performance on
subsequent tests. The authors speculate that this happens because an initial
attempt to construct a response to a question “create[s] a fertile context for
encoding the answer when it is presented.” In other words, the learner
confronted with a difficult question marshals associated ideas and facts in
their effort to come up with an answer; in doing so, she prepares a “fertile context”
which enables her to learn the true answer more deeply when she hears it.
The activity of prediction seems
tailor-made for the edges of a class period. In the opening moments, we can ask
students to make predictions about problems that will be solved in class, about
how theories from last night’s reading might apply to current events, or about
how an experiment will turn out. In the closing moments, we can ask them to
speculate about how the novel they are finishing for the next class will end, about
how the theory presented today might be critiqued in a subsequent class, or
about how a course concept might predict future political events.
