  2. Podcasting:A topic of great interest • See: • www.mercurynews.com • Itconversations.com • Dangillmor.typepad.com This is a podcast!

  3. Agenda • What is podcasting? • Emerging Technology (ET) • Define and understand ET • Where podcasting fits into ET • Disruptive Technology • Define and understand podcasting • Podcasting nuts and bolts • How to create a podcast • Podcasting tools • Summary • Benefits of podcasting • Downside of podcasting • Conclusion, credits and conversation

  4. Emerging technologies of the past • Portable phones once niche players in telecommunications • Hard to use • Cumbersome • Expensive • Now considered one of the three things everybody has • Wallet/purse • Keys • Portable phone • Continuing to change face of society, this tech is still emerging

  5. What is Emerging Technology?What are some emerging technologies? • The adjective emerging has 3 meanings • Coming into view • Coming into existence • Coming to maturity • Internet + Weblogging • The read-write web • Dan Gillmor, “We the media” • User enabling software-hardware • Common computers over 1 billion instructions a second (Super Computers, “Lethal Weapons”) • Media creation applications such as iMovie, iPhoto etc. • Portable devices • OQO, Sony devices, Nokia and “Scoble” phones • Always-on broadband in the home • Cable-DSL • Ubiquitous connectivity, “digital dial tone” • 802.11, Cellular, RSS, (wireless plus download) • See: • www.answers.com • www.bushin30seconds.org

  6. Understanding ET“Disruptive Technology” • Sustaining verses emerging “disruptive” technologies • Disruptive, in this case, means products and technologies that disrupt established solutions and markets, but sustain the underlying process • In an educational setting this can be viewed as methods that offer easier, faster, better and/or cheaper ways improving learning outcomes See: The Innovator's Dilemma, Clayton M. Christensen

  7. Impact of Disruptive Technologies • At turn of the 20th Century the steam train was the transportation system of choice to meet underlying need to get from place to place • Safe • Comfortable • Fast • Relatively convenient • Internal combustion engine could not compete in core market and developed in niche market

  8. Impact of Disruptive Technologies • By end of 20th Century, internal combustion engine has replaced steam engine in what was steam engine’s core market • Steam engine has become niche player • Railroads have declined, focused on freight, and are no longer a predominate mode of long distance travel • Disruptive Emerging Technologies • Change markets, processes and paradigms • Existing paradigms are not secure • Start and develop in niche and often obscure markets

  9. Podcasting and Emerging Technology • Podcasting is a subset of RSS which is a subset of Emerging Technology • Podcasting uses RSS v. 2.0 • Enclosures • Includes video podcasting • XML based • Download based • Not dependent on high bandwidth • Thrives on relatively pervasive connectivity • Technically it is pull technology • Push / pull convergence • Subscription required • Has push characteristics • “Long tail” technology • Infinite number of channels!

  10. Podcasting is • Mixing of the words iPod and broadcasting • A web-based broadcast medium • Audio files (most commonly in MP3 format) • Made available online • Software (like iPodder & xPodder) • Automatically detects new files • Based on RSS v 2.0 enclosures • Downloads the files • For listening at the user's convenience • Allows time shifting • See: • www.wikipedia.org

  11. Understanding Podcasting • A podcast is like an audio magazine subscription • Subscribe to a feed • Subscriber receives regular audio programs delivered via the Internet • Can listen to them at their leisure • Differ from traditional internet audio in two important ways • They can be listened to at any time because a copy is on the listener's computer or portable music player (hence the "pod" in "podcasting") • Are automatically delivered to subscribers, so no active downloading is required • Podcasting is functionally similar to the use of timeshift-capable digital video recorders (DVRs) • such as TiVo which lets users record and store television programs for later viewing • Push / Pull convergence • See: • www.wikipedia.org

  12. Podcasting is not just for audioVideo podcasting!(Vodcasting) • See: • ABC News Video

  13. Any file can be in a feed, “x.casting” • See: • www.feedforall.com

  14. Podcasting is not just for iPods • See: • www.edupodder.com • www.itconversations.com • www.engadget.com

  15. XML code of a podcast • See: • www.edupodder.com

  16. Not just for news!Some uses for podcasting in education • For distance learning • To facilitate self-paced learning • For remediation of slower learners • To allow faculty to offer advanced and or highly motivated learners extra content • For helping students with reading and/or other learning disabilities • For multi-lingual education • To provide the ability for educators to feature guest speakers from remote locations • To allow guest speakers the ability to present once to many sections and classes • To allow educators to escape the tedium of lecturing • To offer a richer learning environment • See: • www.edupodder.com

  17. How to subscribe to a podcast? • Started with iPodder.org • Had to download a client • Note the number of supported platforms! • Find a podcast • Use the tools • iTunes and iPodder have built in directories • You can search on-line or in iTunes • Started with ipodder.org • Note categories • Oh, you can always Google! • You can also selectively download using a browser

  26. How to do a podcast? • See: • www.graperadio.com

  27. Video vs. Audio PodcastingThings to consider

  28. Producing a podcast • There are a lot of options • Macintosh • Use GarageBand and iTunes, etc. • Similar Windows programs • Audacity is cross platform • On-line options increasingly available • Generating Feed • The XML feed can be generated automatically using tools • Feeder is a middle way of generating the feed • You can copy a feed that validates and change the information in the XML file manually

  29. AudioblogEric Rice • See: • www.audioblog.com

  30. This is Odeo • See: • www.odeo.com

  31. Odeo offers some attractive features • Access Control Lists (ACLs) on the roadmap • Can control who can get access to content • Easy to use user interface • Evan Williams, former co-founder of Pyra Labs • Pyra created “Blogger” • Blogger is now owned by Google • See: • odeo.com • Flickr.com

  32. Audioblogger • See: • www.audioblogger.com

  33. Feeder:A feed centric approach? • See: • www.reinventedsoftware.com

  34. One podcasting kit • See: • www.pwop.com Less than $400!

  35. One podcasting kit • High-quality gear that is also compact and affordable • You don't need a computer in order to record your voice • The mic plugs into the preamp. The preamp plugs into the recording device's line input, and the headphones plug into the recording device's headphone jack • Only the preamp requires AC power • Recording device uses a single AA battery which lasts a long time • See: • www.pwop.com

  36. Lifeblog • See: • mobile.kaywa.com • www.nokia.com

  37. Podcasts to Go!Podcasts to/from your phonePodcasting and Skype

  38. Transparency • By nature RSS is transparent • This can be good or bad • Invites the world into the classroom • Some solutions for this • Use application layer security (SSL/SSH) • Tools like Odeo to feature ACLs • Do we adapt to provide more transparency, or do we adapt the tool to provide greater security? • Route around nature of Internet may make it difficult to not be transparent

  39. “When it comes to podcasting, we are all newbies”~Doug Kaye • Tools are making podcasting easier and easier • Podcasting can be done from and to everything from desktop computers to cell phones • The key to podcasting is RSS • Download verses streaming • Low bandwidth tolerant • Podcasts are XML files • Platform and device agnostic • Dependent on capabilities of receiving device • A non-proprietary solution • Extends reach of Internet • Files are local • Works with cell phones • The browser can be taken out of the equation • An entire course can be contained in an RSS 2.0 feed • See: • Itconversations.com

  40. Speech to textvs.Text to speech • Speech to text hard part, the holy grail! • Searchability • Access to hearing impaired • Shares this issue with all content that is speech based • Text to speech huge strength of Podcasting • Can be a channel to supply information to visually impaired

  41. Downsides of podcasting(and RSS) • Depends on a relatively pervasive connection to the Internet at some point • Upside, can be via telco • By nature it is transparent • Major changes in faculty/student relationship • Value of human interaction cannot be ignored • What about the student peer relationship? • Amazonization of education • May prove to be a barrier to faculty and/or students who are tech challenged • Lack of searchability • Potential for information overload

  42. The future of RSS 2.0 “xcasting” • Change of role of podcast journalist • Free Agency or Aggregation Model? • Niche Programming (The Long Tail) • Tons of new tools! • Secure RSS of some kind • ACL’s • Certificate based? • The feed could provide the initial handshake • Increase in types of content delivered this way • Move beyond audio • The aggregator becomes the browser • As E-mail fails, increase in RSS as a trusted source communication channel • Education specific tools • Challenge to browser based solutions • Speech conversion • More searchability • Better metadata
