Slide4: 

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

What is Emerging Technology?What are some emerging technologies?: 

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

Understanding ET“Disruptive Technology”: 

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

Impact of Disruptive Technologies : 

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

Impact of Disruptive Technologies: 

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

Podcasting and Emerging Technology: 

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!

Podcasting is: 

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

Understanding Podcasting: 

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

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

Video vs. Audio Podcasting Things to consider

Producing a podcast: 

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

Transparency: 

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

“When it comes to podcasting, we are all newbies”~Doug Kaye: 

“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

Speech to textvs.Text to speech: 

Speech to text vs. 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

Downsides of podcasting(and RSS): 

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

The future of RSS 2.0 “xcasting”: 

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
