A big challenge for student authors, especially when investigating a topic
they have limited knowledge of— and this would include cases where they might
think they are experts when, in fact, they are not—is fi guring out which sources to
trust. It might be useful to engage students in a discussion of how they determine
(PTSD) among veterans of the recent wars in the Middle East. Rather than relying
on a defi nition from, say, Webster’s, the author would be much better served using
the defi nition given in the most recent edition of the Diagnostic and Statistical Man-
ual of Mental Disorders (DSM). What ever Webster’s has to say would be far too gen-
eral for a paper on PTSD for a psy chol ogy course— even an undergraduate one. You
might ask students to consider this example: you could pres ent it to them as a case
of which source would be the better one and, further, ask why using the fourth
edition of the DSM would be a less effective choice than using the fi fth edition in
terms of presenting trustworthy information. Such a discussion will help students
to realize the need to match the sources they use— even for things like defi nitions—
with the audience(s) they’re writing for in terms of creating an ethos of trustworthi-
ness. Doing so will involve choosing the most relevant and up- to- date information
pres ent (often projecting into the future), and then ending up in the pres ent
moment again. Annual reports and policy documents like the Livable City report
that look toward the future modify this strategy in vari ous ways.
Other strategies include defi ning, describing (generally in rich detail, as in
the excerpts from Gourevitch’s “Mr. Brown” on pp. 270–72), providing concrete
examples, comparing or contrasting specifi c examples cited, and analyzing causes
and effects— basically, any technique that can be used in developing a text. And
as discussed on p. 254, an orga nizational strategy in many of the social and physi–
cal sciences is the IMRAD (Introduction, Methods, Results, and Discussion) format.
Katryn Sheppard’s full essay in Ch. 28 (pp. 620–35) uses the IMRAD format.
