I’m not certain that effective learning would come to a halt merely due to the omission of technology tools in the classroom. However, 21st century skills would be severely lacking and yes, that could affect businesses depending on graduates armed with those skills.

My own experience tells me that the students are learning the technology without the teachers, classrooms and skills. They learn it at home, at their friends’ houses, watching TV and YouTube on someone else’s computer. They learn quickly how to SMS and update a MySpace status page. » More: Does Technology in Schools Guarantee Effective Learning?

Quantum Computers Revolutionalize Information Around 2021

A new revolution in computing may make computers exponentially faster than today.

It’s based on the strange behavior of matter at the quantum level. The basic unit of a quantum computer is a “qubit”—an electron spinning either clockwise or counter clockwise, representing a 0 or a 1. Because electrons can coexist in two places simultaneously, a single electron can carry two qubits, two electrons can produce four qubits, three electrons, eight, and 20 electrons could perform a million computations. The exponential growth raises the hope of infinite processing power.

A quantum computer could easily complete in seconds a task that would take a silicon computer billions of years. The first research prototypes are now running at Harvard University, the National Security Agency, and the Federal Reserve. These revolutionary computers may be on the market in about ten years.

How can social networking support distributed learning?

September 20th, 2009

According to Roy Pea’s “Distributed Intelligence” explication, learning does not simply occur cognitively inside our head. Learning includes social reasoning and intelligence. Learning occurs collectively, socially, when we are gathered and interactive (Pea, 1993).

Pea recommends four environments useful for augmenting our learning. Each of the four mentioned below, underscore the importance of social networking as a viable platform for learning.

1. Augmenting intelligence with computing – simulation.
2. Augmenting intelligence with guided participation – collaborative interpretation.
3. Augmenting intelligence with inscriptional systems – written symbols of language, math, science.
4. Augmenting intelligence with situated cognition – contextual application of knowledge.

We’ve come a long way in just the last three years. Blogging was the ultimate tool for teachers to encourage dialogue in the classroom. However, innovations like SMS and Twitter are changing the game-board on which we play and should be equally included in the lesson planning strategies. Facebook is only ONE social networking application receiving a lot of attention from the education world.

Mobile Learning Frees the Mind? Maybe. If…

I would venture to say most of us in the West do not know how to hunt a buffalo, skin it, prepare and store some of its meat for the winter, convert its hide to blankets and clothing, or make tools from its bones. I guess supermarkets have weakened our minds and we will never know the joy of the hunt or the satisfaction of a good feast after laboring for days. ;-)

Hurdles for Educators Concerning Mobile Learning…

September 15th, 2009
Listen to this Post. Powered by iSpeech.org

Hurdles for educators today concerning the rapid advance of the mobile-learning platform, are:

1. inadequate infrastructure
2. inequity of access to technology across student populations
3. gaps in professional development resulting in lack of use in standards-based lesson plans.

These three hurdles require money and time; two commodities greatly lacking among stakeholders.

I claim these are ‘hurdles today’ because current innovation trends will eliminate the infrastructure hurdle first, the access hurdle second, and time will cure the third hurdle. Question remains, do we have the time to wait??

21 designs for building online collaborative learning communities.

21 designs for building online collaborative learning communities.

I read Chih-Hsiung Tu’s excellent book about Online Collaborative Learning Communities (2004) and gleaned some useful tips for posting your teaching philosophy and what to include in it, according to quoted author and educator, L. Haugen (1998). Read Haugen’s full explanation here or my summary of Dr. Tu’s summary below…

  1. Describe what your students are to learn.
  2. Explain what it is you hope to foster, develop, facilitate, etc.
  3. Define your role and responsibilities as well as those of your students.
  4. Clarify specific ways you want to improve education in your field.
  5. Reference research about shortcomings in your field and how you will address them.

For more help creating online learning communities, get Chih’s book. Chock full of 21 specific designs any educator can begin implementing immediately. A quick and interesting read based on current research-based theory and oodles of practice.

New E-textbooks Grade the Students…

September 9th, 2009
Listen to this Post. Powered by iSpeech.org

Gotta love this headline! Traditional course management systems (CMS) have been fading with the advent of Web2.0 web-based tools. It is being thought among many that CMSs are only good for attendance and grading. But if the online textbook takes care of grading, isn’t a CMS a bit pricey for taking attendance? And is attendance worth measuring in a time-barrier free cyberworld?

New E-Textbooks Do More Than Inform: They Grade You
McGraw-Hill Higher Education is introducing e-textbooks that let students jump from a chapter to the relevant portion of a lecture and get their homework automatically graded.

Connectivism Explained by George Siemens…

September 8th, 2009
Listen to this Post. Powered by iSpeech.org

Recently I engaged in some blog posting with George Siemens and Dave Cormier (see related post) regarding connectivist theory of learning. George clarified his understanding this way…

“Knowledge is an emergent property of the manner in which we connect information.

What does this mean? Well, I have knowledge – a state of personal possession, there is no such thing as knowledge in a magazine or paper – based on how I’ve connected information. For example, when I place value on “social justice” and connect it as part of my conceptual framework and way of looking at the world, this new node influences and shapes what already exists. In a paper in 2004, I suggested that learning networks (I used the term connectivism) site at an intersection of chaos, complexity, self-organization, and network theory. Complex systems exhibit patterns based on the various ways in which its elements interact. And, when we add a learner, we amplify complexity. Knowledge connected (not constructed) will be influenced by the existing knowledge of the learner, her emotional state, experiences during the day, etc.

A person of liberal political orientation will assign value to different sources of information and draw different connections from someone with a conservative political orientation. The “what” (information) is connected (or not) based on the “who” (person) and “how” (medium and accessibility) and a myriad of other factors. We have, I think, much to learn from coming to a better understanding of complex systems.”

Delete Comment Thank you gentlemen, for the super clarifications. Enjoyed Dave’s article; thanks, George, for the link.

Guess we’re still trying to bridge the objective, fixed, Newtonian laws with the contrary, subjective, Quantum mechanics. One explanation of reality is objective, knowable, measurable, and predictable. The other is subjective and obscure. The two worlds mutually indwell each other yet operate by contrary laws. Nevertheless they verifiably exist.

I agree the mental frameworks we construct while learning are subjective and contextual. However, ‘what’ we are observing may be objective and the fact that no individual can perceive the whole without the input of the many, may serve to keep us humble and united. Thanks for the posts.

@Dallas – Dave is too humble to admit it, but he wrote an article on Rhizomatic Education that you might find interesting.

I would take it a bit beyond what both you and Dave suggest: Knowledge is an emergent property of the manner in which we connect information.

@dallas McPheeters I would go further and say that knowledge is something that we create, contextually, while we are engaging with the different streams of information and knowledge that are flowing. I think we’ve struggled, since the creation of writing, to reify knowledge in a way that only makes it confusing. In storing it, we changed it. Now that it gets to remain more fluid, it’s returning to something that is more situational and less objective.

Delete Comment I appreciate Pip Mules’ comment where she notes: “I am interested in the way that incorporating social media into our lives and teaching will change the way we perceive knowledge, and therefore how we will assess knowledge.”

It seems we used to consider knowledge a thing we could possess. It may be however, with the exponential doubling of the knowledge base that we now view knowledge as something we “access” rather than “possess.” Therefore, the most prepared would be those who command the greatest access on a superficial level, and who have the skill to ‘mine’ what they need, on a more intrinsic level.

New Open Source Business Practice of Google…

September 2nd, 2009
Listen to this Post. Powered by iSpeech.org

According to The Wired Campus today, “Google has donated cellphones to 11 colleges and universities for use in introductory computer-science courses this fall, hoping that students will build some interesting applications for the company’s cellphone software.” This is the type of new business practice we will increasingly see as companies compete for market share. Educational institutions shouldn’t wait on the sidelines but encourage creative business-school collaboratives that engage students in 21st century technology skills. Details of the story are here.
