Polar Sea Ice Cap and Snow – Cryosphere Today – iPhone friendly puts data in your hands

Before jumping on the ice-melt bandwagon, we should arm ourselves with the facts. This university science center website offers visual data, both historic and current.

The adaptation to the iPhone demonstrates how education is being changed by hand-held devices. Just this past week, a school in the U.K. gave iPhones to every student. Imagine trying to argue and debate with ubiquitous access to data in the palm of our hands.

Of course, critical thinking skills are still needed to sort through the vast array of opinion and conjecture and to skillfully help others release their death grip on old ideas without losing face.

VoiceThread – Group conversations around images, documents, and videos

Very likely VoiceThread is one of the best Web 2.0 tools for classroom use to come around in awhile. Very powerful and embeddable just about everywhere. Check out this short explanation and try one yourself. Family reunion? Old family pic you wanna post and encourage some comments from others? Too much fun.

But can it improve learning? Certainly fits the constructivist paradigm. How about a self reflection on a themed unit? Or a review of best practices for tech integration for diverse learners? Listening to others think aloud can boost our own critical thinking skills.

Powerful tool with lots of potential. Worth the time and effort to become skilled therein, don’t you agree?

10 Ways Social Media Will Change In 2010

The forces at play here are intriguing, no? Social web is a platform and attitude behind which is a full spectrum of philosophies about what should take center-stage.

Is there an inherent tug-o-war between those wanting to exploit and those merely wishing to connect? Will the psychographic experts hound us and chase us down until we are caught by the enterprising enterprises??

Is the social web the new platform for serving cleverly disguised spam? Mmm… mashups and gravy! My favorite ;-)

What are Educational Technologist Leadership Competencies?

December 1st, 2009

The cool possibilities about the more than 200 real-time web 2.0 tools under development (Like Google Wave) is that sync and async are being melded together along with multi-dimensional communication tools such as voice, text, image, video, etc.

When semantic web becomes the standard (searchable text becomes recognizable object) then tagging and bookmarking values will be reduced and personal and group collections will become more useful.

Such collections will not simply consist of some items “saved” to another location, but more likely will consist of “searched” items and “pointed to” results. http://popurls.com is demonstrating the real-time value of aggregating crowd sourced and theme specific topics. Studying such real-time results can be a great source of discussion for critical thinking development.

The most important quality for Ed Tech leaders is to understand trends and adapt their craft to emerging innovations. Higher education may do students a disservice by focusing too much on tool techniques and too little on trend research.

Community is Not Superficial…

November 5th, 2009

Cooperation is working toward a common goal. Collaboration results in collateral material. However, community may or may not be present and/or result from either cooperative or collaborative efforts.

AND COMMUNITY IS THE GOAL!

Which is why teachers should be careful about assigning cooperative and collaborative work without a clear goal in mind of fostering community.

Community cannot exist without a sense of trust and belonging; a sense that each member’s contribution is valued and necessary; and the belief that what the community produces bears significant impact on MORE than the community itself.

I have pondered this phenomenon a great deal recently due to my position with iMMEDIA and have come up with our Mission statement as follows: Shaping communities of impact through professional development targeting technology integration.

My point is that unless we visionize our student groups with the why; then the “what” and the “how” remain irrelevant and dysfunction results. The assignment may get done but not community resulted and in my opinion, we have done nothing more than drive the herd to market. I find this distasteful to the uttermost.

If there is not impact, members feel like they are given busy work. If the only goal is self enlightenment, members grow tired of the monotony of self centered foci.

If we ask them to cooperate, there must be a bigger reason than the subject matter alone. If we ask them to collaborate, the resulting collateral material should impact a wider audience than the group/class itself. It may work for awhile. But eventually everyone will see through the gloss and look elsewhere to satisfy their innate need to pursue the greater good.

Social Bookmarking’s Ultimate Demise…

October 19th, 2009
Listen to this Post. Powered by iSpeech.org

Social bookmarking began long ago and some of us who are old enough remember card catalogs. Libraries used this social bookmarking system to standardize a way of classifying books by author, title, or Dewey Decimal System.

Social Bookmarking on the web is a 2.0 platform created to allow groups to classify, store, and retrieve internet resources.

What is lacking is a standardized classification system like Mr. Dewey’s decimals. :-)

Hence, the cons already mentioned.

Another con not mentioned is when the link goes dead. Would be like a library book that gets removed. If the card remains in the catalog, many seekers may be led to a vacant shelf. And similarly with the web-based system.

GOOD NEWS though! The semantic web will cure this ailment of dying links. Rather than tying knots to link pages with bookmarks, Semantic Web will tie a pretty bow which can be removed, updated, and re-tied when necessary (or at least we hope so).

I suspect ‘favoriting’ pages will become more useful so that others can search my tagged favorites which will only contain those favorited items that still exist. Make sense?
