Introduction to Podcasting
What Is a Podcast?
iPod
+ broadcast =
podcast
What Is a Podcast?
• podcast:
– An audio (and possibly video) recording that can
be listened to (and viewed) via an iPod, other MP3
player, a computer, or a mobile computing device.
– Many podcasters will offer an RSS feed to alert
users of new podcasts available at the site.
Why Podcasts?
Weather-related schedule
changes and cancellations.
Why Podcasts?
How can I
possibly squeeze
all of this material
into my class?
Pressure to cover
more material in
courses than time
allows.
Why Podcasts?
Professional
responsibilities.
Presenting at a
conference.
Engaged in
research.
Faculty Use of Podcasts
1. Repetition of lecture material covered in class:
– A second look at the material.
– A different approach to the material.
2. Supplement to class activities:
– Remediation for slower learners.
– Enrichment for advanced or highly motivated
learners.
– Assistance for students with certain disabilities.
– Support for English language learners.
Faculty Use of Podcasts
3. Added benefits:
– Facilitates self-paced learning.
– Frees up class time for other group and
interactive activities.
Popularity of Podcasts
• Blurring of work and fun.
• Popularity of mobile computing devices.
In a 2006 study, Student Monitor surveyed
1,200 students from over 100 U.S. colleges
and found that 73% ranked iPods first on
the What is In list, even ahead of Facebook
and beer (Snider, 2006).
Popularity of Podcasts
• Study by the Pew Trusts (Rainie & Madden,
2005):
– 29% of all iPod users have downloaded a podcast.
– Nearly half of all college-age iPod owners have
downloaded a podcast.
• iTunes University currently distributes
thousands of free college-level podcasts from
over eight hundred universities.
Podcasts Improve Student Learning
• Researchers are beginning to find that
podcasting can improve student learning
outcomes.
– McGarr (2009) suggests that podcasting can
improve student learning by increasing student
motivation and engagement.
– McKinney, Dyck, and Luber (2009) found that
students watching a lecture podcast significantly
outperformed a group of students who only
viewed the lecture in person.
Three Steps to Implementing
Podcasting in a Traditional Classroom
1. Choose a medium for delivery that is
appropriate to your technology skill level.
– Podcasting: Use free or inexpensive audio
recording software on a computer to record your
voice.
– PowerCasting: Easily record a lecture within an
existing PowerPoint presentation.
PowerCasting is a term coined by Dr. Steve to describe
an easy & creative alternative to traditional podcasting.
Three Steps to Implementing
Podcasting in a Traditional Classroom
2. Choose material that is appropriate for
podcasting.
a) Ideally, select course topics:
• Can be presented at any time throughout the course.
• Independent of material you are presenting in class at
that time.
Allows you to introduce podcasted topics whenever a
schedule change occurs.
Three Steps to Implementing
Podcasting in a Traditional Classroom
b) Choose material that is easy for students to
grasp after one hearing, and that does not
require two-way interaction.
c) Alternatively, choose more technical or tedious
material that students might want to hear
several times (e.g., chemical names and symbols,
names and dates, lists, sequential steps in a
process). Remember that students can control
playback of material.
Three Steps to Implementing
Podcasting in a Traditional Classroom
3. Deal upfront with the validity of the
assignment as a part of the course
requirements.
a) Establish a policy of reserving the right to switch
to “distance mode” during a cancelled class.
b) List the policy in your syllabus, and indicate how
you will communicate when you are switching
into this mode.
Three Steps to Implementing
Podcasting in a Traditional Classroom
c) Create an assignment to accompany the
podcast, one that will require that the students
have listened to the podcast.
• As you introduce the assignment, caution students that
they must be able to hear the podcast.
Three Steps to Implementing
Podcasting in a Traditional Classroom
d) Specify an appropriate due date for the
assignment that accompanies the podcast.
• In my experience, many students will view the
cancelled class as a “day off” and will complete the
assignment at a much later time, unless this material is
required in preparation for the next class meeting.
e) Refer to the material that was contained in the
podcast at a subsequent class lecture, or hold a
follow-up in-class discussion about the material.
Questions/Discussion
• Could podcasting or PowerCasting benefit
your classroom? How?
• When might you use this technology in your
classroom?
• Any thoughts or questions so far?
PowerCasting with PowerPoint
PowerPoint and Podcasting
• “True” podcasting:
– Audio (possible video).
– Syndication capabilities (RSS feed subscription).
• PowerCasting (PowerPoint podcasting):
– Easy way to add “podcasting” to your teaching.
– Focus on content, not on the tool.
– Utilize presentations you already have.
Examples of PowerCasts
• Let’s listen to some examples of PowerCasts I
have used to help students learn remotely
about various technology concepts.
“Safety Issues”
“Copyright”
“Programming”
Narrate an Entire Slideshow
• PowerPoint will allow you to record
continuous narration (lecture) as you run the
slideshow as you usually would in class.
• As you narrate, the time you spend on each
slide is also recorded. (You can opt
to use or dismiss the slide timings
at any time.)
Edit the Narration
• In reality, PowerPoint records a separate
narration for each slide. This allows you to:
– Preview each slide narration individually.
– Edit the sound for each slide individually.
– Begin re-recording from a particular slide,
stopping at any point.
Steps in Recording Narration
Purchase an audio
headphone instead of
a hand-held
microphone to
increase quality.
Steps in Recording Narration
Select this tool to begin
recording the narration.
Steps in Recording Narration
• Set microphone level (in Office 2003).
Set up and
adjust
microphone if
needed.
Steps in Recording Narration
• After you hit “OK,” the presentation will run as
usual.
– Recording begins immediately. Begin speaking.
– Advance slides by clicking as usual.
– If you are using custom animation, click during
narration as usual.
• Hit ESC to end early, OR record until you hit
the end of the presentation.
Steps in Recording Narration
• PowerPoint will ask if you want to save the
slide timings.
After recording
in PP 2003.
Before recording
in PP 2010.
Hint When Recording Narration
HINT: On each slide, pause for
1 second before and after
speaking to ensure all of
your words are recorded.
When a Student Listens
• When the slideshow is played back:
– The presentation automatically advances using
your saved slide timings (if you saved them).
– If a student begins playing the slideshow from a
particular slide, the narration begins from that
point.
– A student can click to advance the slide early,
clipping your sound file.
Editing Narration
1. Navigate to the slide you want to re-record.
2. Select slideshow—record narration.
– Continue recording on subsequent slides.
– Press the ESC key to end recording.
PowerPoint Extras
• You can also add any of these PowerPoint
interactive “extras”:
– Use animation to build slides and maintain
learner attention.
– Navigate to a Website using an action button.
– Link to files (documents, spreadsheets).
– Embed or link to a video.
– Use animation to provide embedded questions
about the lesson, and triggered animation to
feedback.
LET’S TRY IT!
•
Let’s try recording continuous narration
using a PowerPoint presentation to create a
PowerCast.
Remember:
•
–
–
Recording begins immediately.
Advance the slides as usual – your timings are
saved as well.
Distribution of PowerCasts
• PowerCasts are just files. How can you
distribute them to students?
– Post on BlackBoard.
– Post on a course Website.
– E-mail directly to class members.
– Burn to CD-ROM.
Questions/Discussion
• How might you use PowerCasting in your
classroom?
• What types of material might be suitable to
offer through podcasting in your classroom?
• What potential problems might you encounter
in incorporating PowerCasting into your
classes?

Scripting a Podcast
• Prepare – don’t make it up as you go along.
– Moderate end: Create a bulleted list/outline.
– High end: Create a script.
• Don't focus on creating the perfect script for
your podcast. You don’t have to follow the
script exactly when you record—use it as a
guideline.
Once you have created an outline for your podcast,
use it later to make notes to publish later in your
blog.
