I stumbled upon the joys
of podcasts when I was trying to make the DC and Baltimore traffic more bearable.
Now I say, “Traffic is backed up for 10 miles due to a car crash? Whatever - I
will just sit here and enjoy my podcast.” Of course, I started with podcasts
for fun, such as This American Life, Car Talk, Writer’s Almanac, and Wait,
Wait Don’t Tell Me. Then, as a fourth year student, I realized I could
listen to medically oriented podcasts as a way to keep up with new studies and
guidelines. This became especially useful as a PGY-1 resident. I recently found
myself short on time to prepare for a topic discussion on JNC8 (the new hypertension guidelines). Well, there’s a
podcast for that! After listening to it on my way home, I was able to more
quickly review the guideline document and prepare my notes for the discussion.
Since I love learning from podcasts so much, I suspect other learners might
find them useful too.
A recent study in the
Proceedings of the National Academy of Science found that STEM students who sat
through traditional lectures were 1.5 times more likely to fail than students who
were taught by professors that incorporated active learning techniques.1
However, incorporating active learning can be a challenge given the large
volume of material educators must cover in a pharmacy curriculum. While perhaps
not as flashy as video podcasts (aka vodcasts or vidcasts) with their dual
audio and visual components, we shouldn’t forget that podcasts are a useful
tool to free up time for active learning and flip the classroom. Podcasts are
easier to create than vodcasts, take up less computer / device memory, and
allow the listener to multitask, to a certain extent. Commuting, dishwashing,
and laundry folding can be turned into productive, intellectually stimulating
time with a great podcast on your mobile device! Don’t get too carried away
with trying to multi-task though, lest you interfere with your ability to
process and learn new information! (See The Multi-tasking Myth: Technology Use andInstruction Outcomes by Brent
Reed, Pharm.D., BCPS for more information.)
When podcasts were first
introduced as a teaching tool in higher education, they were largely viewed as
an add-on learning tool to a traditional lecture. Many studies demonstrated their utility when
used by students to review material.2 In one recent study, dental
students who received supplemental podcast instruction were shown to have
statistically significant improvement in scores on a multiple-choice test with
91.3% of the students reporting the podcasts were useful. However, 63% thought a podcast would be
inferior to having audio and video.3 The effectiveness of podcasts
versus vodcasts has not been evaluated but a study where lectures were offered
through Mediasite (video) and as podcasts, more students accessed Mediasite
recordings than listened to podcasts.
Thus, students appear to prefer video to audio only formats. But educational
outcomes were not measured in this study.4
Some educators have
evaluated the use of podcasts as a replacement for traditional lectures. In
2013, a small study (n=35) found that undergraduate nursing students who
listened to a 51 minute pharmacology podcast broken into 3 separate segments
scored higher on a multiple-choice and case-based assessment than did students
who received the same material via a traditional face-to-face lecture or a continuous,
non-segmented podcast. The difference in scores did not meet statistical
significance (due to the small sample size) but there was a clear trend. It
should be noted that the study did not include a student group taught using a series
of short, segmented face-to-face lectures – but, lets face it, that’s probably
not practical in terms of room scheduling.2
Podcasts are not just used
for formal education in degree programs; many professional societies and
journals deliver new research and guidelines through podcasts. The Society for
Critical Care Medicine (SCCM) was the first to produce a podcast for a national
medical society; its podcast iCritical Care features interviews with leaders in
the field of critical care medicine. Both the New England Journal of Medicine
and the Journal of the American Medical Association offer weekly podcasts
summarizing their latest issues. The American Journal of Health-System Pharmacy
produces a podcast that features studies it publishes. Other pharmacy news
sources with podcasts include Pharmacy Times and Pharmacy Practice News.
Assigning students a podcast versus a reading would introduce them to this
technology as a potential method for engaging in continuing professional
development after graduation. These podcasts can be found in the iTunes store.
If you want to make your
own podcast to supplement or replace a classroom activity, it’s both easy and
affordable. Audacity is free software that allows the creation and editing of
audio files. It’s available for numerous operating systems, including Mac,
Windows, and Linux. If you have a Mac, you have built in audio creation and
editing software — Garage Band comes on all Macs and can be used to create and
export podcasts. If ambient noise interferes with your recording, you can use a
USB headset with a microphone.
Podcasts can be delivered
through a secure Learning Management System, such as Blackboard, or they can be
made freely available on the web. The latter option allows use of Really Simple
Syndication (RSS), so students can subscribe and receive updates as new
podcasts are uploaded. Rosalind Franklin University College of Pharmacy shares
its podcast, Helixtalk, using the latter option. In either case, it is
important to review how to access and download podcasts with students as knowing
how to use the technology can be a barrier for some students.5 It
might also be helpful to highlight that podcasts can be downloaded to mobile
devices. In a study of nursing students, 70% of students who listened to
podcasts played them on a computer, even though 73% of the students had mobile
devices capable of MP3 playback.6 This indicates students may not
know or appreciate the advantage of mobility offered by a podcast.
While podcasts don’t
provide visual information like vodcasts, they can be used to augment live
classroom activities, video, and readings. Rosalind Franklin College of
Pharmacy’s podcasts focus on information relating to the Top 200 drugs and
provide students with an additional way to review material. Similarly, short
podcasts could be used to highlight essential material from a course, clinical
controversies, or provide clarification on those muddier points that baffled
students during lecture. By introducing podcasts as an educational resource in
the classroom, educators can expose students to a technology they can use to
stay abreast of new knowledge for the rest of their careers. I look forward to
including podcasts among my learning assignments as I embark on my career in
pharmacy education.
