As part of a composition course, students were asked to write
an expository piece on a scientific topic in a manner appropriate
for a lay audience. In preparation for this assignment, students
were given many models to examine including excerpts from
Annie Dillards Pilgrim at Tinker Creek, articles
from The New Yorker, and articles from The New
York Times science edition.

What the work shows
a
Writing: The student produces a report that:
engages the reader by establishing a context, creating a
persona, and otherwise developing reader interest;
develops a controlling idea that conveys a perspective on
the subject;
creates an organizing structure appropriate to purpose, audience,
and context;
includes appropriate facts and details;
excludes extraneous and inappropriate information;
uses a range of appropriate strategies, such as providing
facts and details, describing or analyzing the subject, narrating
a relevant anecdote, comparing and contrasting, naming, explaining
benefits or limitations, demonstrating claims or assertions, and
providing a scenario to illustrate;
provides a sense of closure to the writing.
The work
engages the reader immediately with a provocative question and a
humorous response.
The work establishes the persona of a knowledgeable person in the
third paragraph when the student gives some of the scientific information
behind the initial conversation.

Writing: Produce a report. |
The work
develops a controlling idea that conveys a perspective on the subject,
i.e., that most of us have not been aware of the fact that flowers
usually contain both the male and female reproductive organs. This
phenomenon is explained throughout the work.
The work
creates an organizing structure appropriate to a specific purpose,
audience, and context. For example, the work makes the assumption
that most people have limited knowledge on this topic, and, in order
to help the novice reader, goes from the general (Did you
know fruits are ovaries?) to the specific (the explanation
of cross-pollination).
The student successfully engages and maintains the readers
interest by addressing the audience directly as you.
The work incorporates information drawn from multiple sources. The
student utilized two reference texts and interviewed two experts
on the subject.
The work incorporates a range of appropriate strategies, such as:

the inclusion of numerous facts and details to explain the role
of fruit in plant reproduction;
the use
of simple, concrete language to explain the subject to a lay audience;
the use
of humor in the initial conversation and throughout;
the use
of a conversational tone which is successful in imparting scientific
information while keeping the reader engaged; and

the use of metaphorical anecdotes and pedestrian terms to convey
complicated information.
The work
provides a sense of closure. After providing numerous details throughout
the report concerning how flowers become fruit, the student explained
at the end how some flowers have actually evolved to the point where
they look, smell, and feel like female bees, thus further
serving the process of pollination.
There are some errors in spelling (e.g., pistol instead
of pistil), and usage (e.g., it instead
of its at the bottom of page 14 and flowers
instead of flower at the bottom of the third to the
last paragraph).
The report contains some errors of science. The work does not stick
with its original purposeto explain how flowers become fruit.
It digresses into an explanation of pollination and fertilization
but does not fully explain this process either.
There are some errors in terminology, for example, the term pistil
is generally no longer used and the stamen is not necessarily yellow.
Also, in the second last sentence of the first page, the student
used the term bond when fuse or meld
would have been more appropriate words to describe the process of
the sperm combining with the egg to form a totally new entity.
The description of the reproductive parts of the corn, the function
of the wind in corn pollination, and the generalization that the
stigma must come in contact with pollen grains from another flower
in order to reproduce are incorrect.
