Definitions and Examples
• Podcasting: “distribute (multimedia files) over the internet for playback on a mobile device or a personal computer” (Wordnet)

Value for Teaching & Research
• OF COURSE: record your lectures for your class• BUT: There are many other pedagogical uses:– Record presentation in one context and provide as
supplementary info in another class or context– Record presentation in face-to-face class to
possibly use online– Record your presentation at a conference to
disseminate it more broadly via your CV, etc. (some conferences are now run this way)

A bit of media history/theory
• Podcasts (audio, video, synchronized .ppt) capture and recast the “lecture”
• Lecture: action of reading, perusal: “That face, whose lecture shewes what perfect beautie is” (Sydney, 1586)
• Words not separated scripta continua
• St. Ambrose of Milan: some say hewas the first to read silently

Lectures as Reading Aloud• Was a way of reproducing texts
before the printing press• A text by an ancient authority
would be “read”• One of the first people to
lecture by reading text of their own composition was Fichte, in the 1790’s

Contradictory form of Lecture
• “Guide on the side” vs. “Sage on the stage”• “Chalk and Talk;” “industrial model” • Randy Pausch Last Lecture; Walter Lewin,
lectures on classical mechanics• mediatrans.ca/test/Sean_B_Franzel.html• New Media Studies Centre: nms.tru.ca • Lecture as oral genre; combines with
text/multimedia with great flexibility

Technology needed for Slideshare
• Presentations: pdf, ppt, pps, pptx, ppsx, pot, potx (Powerpoint); odp (OpenOffice); key, zip (Apple Keynote).
• Documents: pdf, doc, docx, rtf, xls (MSOffice); odt, ods(OpenOffice); Apple iWork Pages
• MP3: the only audio format• 100 Mb upload limit

Technology: Second Option

the last 4 years will have a mic built in

Audio editing & converting
• Free software (is good for recording on your laptop too)
• Need to download a separate file for .mp3 conversion: http://learningspaces.org/lame_enc.dll
• Will demonstrate this later• Can upload mp3 file in isolation
for download

Tips and Tricks
• Try different settings in converting audio to mp3 to “satisfice” file size and quality
• Use a photo (with an appropriate CC license) from Flickr for your title slide
• You can delete the “ums” and “aahs” from your audio file easily using Audacity
• Re-load the audio-to-slide synch tool in Slideshare if controls not showing initially
