We are all time travelers... drifting through time at a steady pace, one moment at a time. In what direction are we moving through time? Or does time move through us? How many dimensions of time are there? Though slightly allegorical, three-dimensional time offers physics new parameters, accounting for conventional and exotic physical phenomena, while maintaining the conservation of energy and symmetry groups found in physical law.  I began playing with the idea that all of physics could be reduced to just interactions between spatial and temporal coordinates. I wondered if inertia and momentum might be composed strictly of temporal components. This would require extra time dimensions. Could inertia or momentum be used as indicators of multi-dimensional time? What about charge, spin, and other properties of matter? Answers to some of these questions appeared to reside in neutrino research, specifically neutrino flavor oscillation.  The universality between Thermodynamics and Temporal Mechanics can reduce the fundamental forces of nature into a single expression, a new equivalence principle, which can be used as the generator for the evolution of time. Once Quantum Mechanics is seen through the lens of three-dimensional time, the EPR paradox looses its mystique. The speed of light may be restricted to a set speed limit within each individual frame of reference, however, frames of reference can undergo periods-of-time at varying rates of the passage-of-time. If the positive side of absolute zero is a state of condensed matter, what is on the negative side of absolute zero? Uncondensed matter?  The anti-matter aspect of the Dirac equations may have been misinterpreted. The convention is to assume that "matter" is composed of "particles" distinctly different from "antimatter" composed of "antiparticles". The assumption of one time dimension locks in this interpretation of the Dirac Equations. However, the uniform production of particles and antipa

"Conversation is key . Sawyer succinctly explains this principle: "Conversation leads to flow, and flow leads to creativity." When having students work in groups, consider what will spark rich conversation. The original researcher on flow, Mihaly Csikszentmihalyi, found that rich conversation precedes and ignites flow more than any other activity.1 Tasks that require (or force) interaction lead to richer collaborative conceptualization. Set a clear but open-ended goal . Groups produce the richest ideas when they have a goal that will focus their interaction but also has fluid enough boundaries to allow for creativity. This is a challenge we often overlook. As teachers, we often have an idea of what a group's final product should look like (or sound like, or…). If we put students into groups to produce a predetermined outcome, we prevent creative thinking from finding an entry point. Try not announcing time limits. As teachers we often use a time limit as a "motivator" that we hope will keep group work focused. In reality, this may be a major detractor from quality group work. Deadlines, according to Sawyer, tend to impede flow and produce lower quality results. Groups produce their best work in low-pressure situations. Without a need to "keep one eye on the clock," the group's focus can be fully given to the task. Do not appoint a group "leader." In research studies, supervisors, or group leaders, tend to subvert flow unless they participate as an equal, listening and allowing the group's thoughts and decisions to guide the interaction. Keep it small. Groups with the minimum number of members that are needed to accomplish a task are more efficient and effective. Consider weaving together individual and group work. For additive tasks-tasks in whicha group is expectedtoproduce a list, adding one idea to another-research suggests that better results develop

Editorial about a recommendation by the AFT Pres to develop a professional certification for teachers.  It's about time...

Mark & Michelle, thank you for your comments. When I posted this I knew the words "standardized test" would be a flashpoint. It is for me too. With nearly 40 years in the classroom, teaching a creative art (music) to all different levels (kindergarten through college and well beyond), I have often railed against reducing any education, any student, to a number. Very little in what I have taught can be measured with a pencil-and-paper test. What I see here is different than this. It is the union that she is saying should be the "gate-keeper" to our profession, rather than some generic government standard test. Yes, tests would be a part of the certification, but from what I read, so would much more, including actual classroom work. The certification would be similar to the AMA for physicians or the Bar for attorneys. These are certifications designed and administered by the profession - not the government - and validate a candidate's readiness to practice. Yes, I too am strongly against the government, or any organization outside of our profession, to certify, to validate, a teacher's ability to do the job. But we have to admit there is a problem with teacher certification and validation. There are people who simply should not be in the classroom (haven't we all seen them?). It is very difficult to remove folks who are dragging the respect for our profession down. Yes, there is remediation. Yes, it should be a difficult process to remove someone in order to protect against administrative abuses. But what is talked about here is the profession policing itself - something that the teacher's unions, in general, have steadfastly refused to do. What the AFT Pres is suggesting is that the best thing we can do to raise the status of teaching as a profession is to take action ourselves to make it happen. Really, if we in the profession do not do this, then it will be imposed from those outside who do not know what we do, how we do it and why we do it.

You are still talking about a standardized test. Let's face it--doctors have to have specific knowledge to do their job. Whether or not they are creative or engaging is not as important as their knowledge base. The same with lawyers--knowledge of the law is essential, and everything else is secondary. However, in teaching, although educational theory and knowledge of their subject area is important (and already tested, by the way) the most essential aspect of teaching is how you can creatively engage students, interact with parents and peers, and stay organized and motivated. These things CAN'T BE TESTED. Right now, teachers already go through extensive training, evaluation, and continuing education. Do you REALLY think that a standardized test will really improve teaching? I know a lot of university professors who can easily pass a test, but few of them can teach worth beans.

MacArthur Foundation Study - Friendship chapter

"I thought it was appropriate to ask the question to my PLN (or what I perceive as my PLN) via Twitter. I asked if anyone had a definition for a PLN, or if they knew the difference between a personal learning network and personal learning environment (PLE). I received varied responses, and the majority of these are pasted below."

As we work together to restore hope to the future, we need to include a new and strange ally-our willingness to be disturbed. Our willingness to have our beliefs and ideas challenged by what others think. No one person or perspective can give us the answers we need to the problems of today. Paradoxically, we can only find those answers by admitting we don't know. We have to be willing to let go of our certainty and expect ourselves to be confused for a time

what if our expertise is imagined or false. What if what we think is so, just ain't so. This might be more common than we care to admit, and it is worth considering the source of this difficulty and its implications. 

What if every student (and educator) was a good online researcher?  I know, you don't have the time to teach information fluency skills.  What if you could get a significant advance is skills with just a 2 -3  hour time commitment?  Here's a great Prezi 'fly by" of the new Information Investigator 3.1 online self paced class.  Watch the presentation carefully to find the link to a free code to take the class for evaluation purposes. 

Of course you could always have you school librarian/media specialist teach information skills to your students! That's what they do!

I couldn't agree more. Library Media Specialists, especially when they can collaborate with classroom teachers, are the best resource for teaching these skills. However the problem of access to a Librarian and the issue of scale are real barriers. I've been creating content for Librarians for a decade. They are the best! You'll find years of free resources at: http://21cif.com This resource will help them reach more students. We had 1000 teens take this course at the Center for Talent Development. It really does work. We're hoping to reach teachers and librarians everywhere so we can pass along the skills and the opportunity. If American education was marginally rational there would be professionally staffed library media centers in every school. Since that isn't the case, I hope Internet based resources can keep the lights on for a new generation that really needs information fluency.

"What to do if your batteries leak out into a device of yours, and how to prevent it happening in the first place."

Adults love to ask "What if...?" questions too. It is a model that can be a catalyst for change when used in the right way and when combined with some other questions.
