was team teaching; now FACTS?

While I agree that students do not remember all of the details that have
been presented to them in each course, one of the advantages to presenting
a wide array of content is that students become at least vaguely familiar
with terminology and information that they will eventually remember. In
other words, a "fact" that they have been presented with in a first year
course may not be remembered specifically, but when they hear about that
fact again in another course they remember their previous exposure to it
and are more likely to absorb it. I am a firm believer that many students
learn content only after repeated exposure (and use). One of the major
pieces of evidence that has led me to this conclusion has come from my
involvement in a team taught organismal course taught to our freshmen.
Many of our students come to us from high schools that have focused on
animal and/or human biology (often the equivalent of a human anatomy and
physiology), and have given little attention to plant biology. These
students complain that plant biology is SO hard and that the words used in
plant biology are impossible, but they are not bothered at all with the
words that are used to name the bones in the human body, or the processes
occurring in humans. Those few students who DID receive reasonable
exposure to plants in high school are not as likely to believe that plant
biology is any harder than animal/human biology. If they are not
intimidated by first time exposure to terminology and concepts they are
much more receptive to them in my course.
So, to belabor the point, sporophyte and gametophyte generations are
impossibly confusing the first time around, less intimidating with repeat
exposures. This is not intended to argue against teaching process, or
active learning. It is just a reminder of one of the many reasons why
content is important as well, even in introductory level courses. My
personal contribution to the problems posed by a lack of plant exposure in
the grade schools is to volunteer early and often to give presentations
about plants in the local schools. Unfortunately, this can only be done
in those grade levels in which plant biology is an official part of the
curriculum, which in some school districts ends at 7th grade.
