THE PERILS OF POWERPOINT
Thomas R. McDaniel, Converse College, and Kathryn N. McDaniel,
Marietta College
College professors everywhere are incorporating PowerPoint presentations
into their classroom lectures. Faculty often pressure their deans
to make every classroom a "smart classroom," and those
fuddy-duddy faculty too slow to embrace this quickly-emerging
technology are considered Luddites, resisters to change, out of
step with modern student expectations. Technology can be a boon
to pedagogy, but it is not without its perils. Before jumping
headlong into the rushing tide of PowerPoint presentations, consider
these cautions and criticisms about this popular teaching tool:
1) It's Inflexible.
When you use PowerPoint to convey information and ideas, it limits
not only the content you can convey, but also the pace at which
you present. If a student has a question (which the format of
PowerPoint discourages anyway), the presenter may lose the flow
of the PowerPoint in trying to answer it. If the student's question
requires a quick jump ahead to a later point, the presenter will
(if the program will allow it) have to scroll through upcoming
points to address it. This can lead to confusion and a sense of
disorder for both the presenter and the students. If the presenter
has included too much information on the slides, students may
delay the presentation by insisting that they "haven't finished"
copying everything down. If you find out that your audience has
a different level of knowledge than you expected (for example,
if they didn't do the reading they were supposed to), the presentation
cannot easily be adapted to fit the new situation. What all of
these "ifs" demon!
strate is that there's insufficient flexibility in the presentation
form to allow for any surprises-those wonderful "teachable
moments" that energize a lesson.
2) It's Risky.
How many times have you seen a PowerPoint presentation where
some technical difficulty
a) made it impossible to start the presentation on time?
b) caused the presenter to lose the presentation entirely and
end up fumbling halfheartedly
through the presentation?
c) made it difficult to change the "slides," making
every transition a long or clumsy process?
d) created a problem with the sequencing of points such that the
presenter lost his or her place?
e) all of the above?
Technology is a wonderful thing, but its use also opens up all
kinds of possible delays and technical difficulties. The real
trouble with PowerPoint technology is that the presenter becomes
too dependent on it and often cannot simply abandon the technological
"enhancement" to perform the lesson anyway when technical
difficulties arise, as they invariably do.
3) It's a Crutch.
PowerPoint often serves as a crutch that prevents academics from
developing real teaching skills. This is particularly a problem
for academics who have spent most of their training in relatively
isolated activities (researching in labs and libraries and then
writing up their research) and who often have introverted tendencies.
Instead of having to develop a pedagogy that engages the class
at some level, instead of having to learn to communicate ideas
to the individuals within the class, the professor can spend hours
laying out a PowerPoint presentation that resembles a scholarly
publication more than a lesson and that presents the information
in a way that stifles communication between teacher and students.
This is "presentation," not teaching.
4) It's Boring.
One of our students talks about PowerPoint classes as a "Zone-Out
Zone." Not only is it easy for students to zone out during
a presentation, it's often actually difficult for them to stay
focused and attentive. This occurs for several reasons. First,
a PowerPoint presentation seems to signal to students that they
will not be necessary for the next 50 minutes or so, that their
presence is purely as an audience, and as a result many students
automatically disengage even at the very outset. (Having the lights
out provides a cue.)
Second, presenters often put all of the salient points of the
presentation on the slides, bullet-pointed for clarity-and sometimes
they even distribute a handout of the information on each slide.
Why does a student need to listen to the presenter read through
each of these, even if there is a longer explanation? The pacing
seems to slow down painfully; the students never have to figure
out for themselves what the key ideas or points are; they have
become merely scribes, copying down information. No matter how
many "cool graphics" you have, if they don't relate
to the material (and are just "frills"), students will
tune out everything of substance.
5) It's Style without Substance.
The stylish presentation that PowerPoint offers often occurs
at the expense of substance. Instead of spending time researching
and studying the content, the presenter spends hours figuring
out how to have the bullet points "fly" in. Examples
end up watered down because of technological limitations or the
lack of an appropriate graphic. Complex ideas are reduced to bullet
points and clever images which don't allow for nuance, multiple
perspectives or definitions, or points of contention. Excessive
stylish features slow the pace of the lesson and reduce the amount
of material that can be conveyed effectively.
Even the best PowerPoint presentation is impressive not because
of the insights and ideas conveyed, but because of the skilled
use of technology it represents. In thinking about whether or
not a PowerPoint presentation was effective, people will often
focus on the technologies used, the frills and graphics, the smoothness
with which the technology functioned. This is the last thing you
want students to be getting out of your lesson-that you, the teacher,
are good with technology.
Like Any Tool . . .
While PowerPoint can be a great addition to a teacher's pedagogical
repertoire, it is no magic bullet guaranteed to make professors
better (and more impressive) teachers. Like any tool, it can be
misused or abused, and when that happens teaching effectiveness
may be undermined instead of enriched. Effective pedagogy means
knowing the benefits of any given teaching tool. Those who know
the "perils of PowerPoint" are most likely to avoid
its pitfalls.
