Science Debriefing
Higher-level learning
demands that students review, organize, analyze, clarify, interpret,
and evaluate new information. Personal meaning is created, and other
questions are generated for future thought. All of these processes
are internal. Direct observation will provide little evidence of student
effort or mastery. A structured debriefing in which students are asked
to verbalize their learning can provide indicators of progress. In
addition to monitoring student comprehension, the teacher has the
opportunity to supplement, correct, or elaborate on student perceptions
during debriefing.
Debriefing is significant in the learning sequence because it can
enhance comprehension in several ways. First, learning studies indicate
that the encoding of information in memory comes about because of
active processing and elaborating of material to be learned toward
the end of the process. It is then that new material is integrated
in meaningful ways with information already stored. Second, studies
indicate that learning processes leading to deeper understanding
are enhanced by, and may even depend upon, dialogue and interaction
with other persons. Third, research indicates that review affects
the level of mastery and comprehension. A period of debriefing brings
about each of these conditions.
Debriefing is significant because it allows for a check on the
level and accuracy of student comprehension of the unit just studied.
Research has demonstrated that individuals monitor their own learning
poorly, even when they are capable of doing so. Research has also
shown that active participation in checking other people's work
improves learning; this affirms the value of feedback that students
receive from dialogue during the debriefing period.
Debriefing strategies can be as simple as "think alouds" in which
students share their understanding of material they have experienced.
More complex activities include keeping journals that are read aloud
or composing a story that assumes a role for themselves. Similarly,
students could represent key themes or concepts pictorially or graphically,
or rank processes or events in their order of importance. It is
the dialogue from these activities that allows both teachers and
students to profit from the debriefing.
