This week, Stanford has started to roll out a new course, Einstein's General Theory of Relativity. Taught by Leonard Susskind, one of America's leading physics minds, this course is the fourth of a six-part sequence - Modern Physics: The Theoretical Minimum - that traces the development of modern physics, moving from Newton to Black Holes. As the title suggests, this course focuses squarely on the groundbreaking work of Albert Einstein. And, it's undoubtedly a plus that the course was presented in Stanford's Continuing Studies program, which means that it's tailored to smart non-specialists like you. You can watch the first lecture on iTunes here, or YouTube below. The remaining lectures will be rolled out on a weekly basis. If you would like to watch the longer sequence of courses, I have provided a complete list of links here. Enjoy.

In the heart of the home of the concept inventory--Physics

The argumet for external stakeholders is underscored, among other implications.

""We think that humans build relationships precisely for this reason, to distribute problem solving across brains," said James A. Coan, a a psychologist at the University of Virginia. "We are wired to literally share the processing load, "

A biological aspect of social learning, in an article about the power of human physical contact.

"The professor said he did find a way to greatly reduce cheating on homework in his class. He switched to a "studio" model of teaching, in which students sit in small groups working through tutorials on computers while professors and teaching assistants roam the room answering questions, rather than a traditional lecture. With lectures, he detected cheating on about 11 percent of homework problems, but now he detects copying on only about 3 percent of them. It might help that he shares findings from his study to his students, showing them that cheaters are much more likely to get C's and D's on exams than those who work out homework problems on their own. "

A physics professor figures out how to detect cheating on homework, (an assessment), triangulates with another assessment (OK, it's an exam) to determine the impact on student learning, and modifies his teaching practice, reducing cheating from 11% to 3%.

This is a happy ending and an interesting useful outcome from assessment. There is also a kind of "duh" quality to it, but that is not a problem. What I'm pondering, though, is the time and energy expended for a 7% gain. What I hope follows is further assessment of the gains for the other 93% relative to learning and attitude toward learning, school, and the subject matter.....

Lumina Foundation pushes a Eurpopean-style process to define education goals state- and nation-wide, with mixed success. "Chemistry, history, math, and physics have been among the most successful", whileothers have had a hard time beginning. "Supporters of the Lumina project say it holds the promise of turning educational assessment from a process that some academics might view as a threat into one that holds a solution, while also creating more-rigorous expectations for student learning. Mr. Jones, the Utah State history-department chairman, recounted in an essay published in the American Historical Association's Perspectives on History how he once blithely told an accreditation team that "historians do not measure their effectiveness in outcomes." But he has changed his mind. The Lumina project, and others, help define what learning is achieved in the process of earning a degree, he said, moving beyond Americans' heavy reliance on the standardized student credit hour as the measure of an education. "The demand for outcomes assessment should be seized as an opportunity for us to actually talk about the habits of mind our discipline needs to instill in our students," Mr. Jones wrote. "It will do us a world of good, and it will save us from the spreadsheets of bureaucrats."

"So far, the most useful tool to me, in physics, has been the rubric, which is used widely in grading open-ended assessments in the humanities. "

A focus on improving the grading experience, rather than the learning experience, but still a big step forward for (some) hard scientists.

In spite of all the as-of-yet unexploited benefits of technology, there is quite a lot to be said about physical interactivity..

Fine piece, transformative. "were students given the opportunity to attempt the assessment, without the requirement that they sit through lectures or otherwise proprietary forms of learning, then they would create their own learning resources."

"The difference between the alchemists and the chemists was that the printing press was used to coordinate peer review," he said. "The printing press didn't cause the scientific revolution, but it wouldn't have been possible without it." "The difference between the alchemists and the chemists was that the printing press was used to coordinate peer review," he said. "The printing press didn't cause the scientific revolution, but it wouldn't have been possible without it."

and at sub-group significance compared to interaction. She concludes: 'Readers should have a particularly high index of suspicion for controlled studies that fail to report between-group comparisons, because these likely represent attempts to "spin" null results."

"# Google says hackers from China got into its Gmail system # Bruce Schneier says hackers exploited feature put into system at behest of U.S. government # When governments get access to private communications, they invite abuse, he says # Government surveillance and control of Internet is flourishing, he says"

A security expert looks at who's spying on whom... (hint: it's not just China)

But China is clearly among the most aggressive in this area. I remember being taught in the military that most espionage is industrial (by governments for industry) but Universities are also targets for various classified research, such as DARPA funded research. I think of perhaps shock physics, for example. Certain kinds of spying are essential for peace--that which is to determine "intent" of the other helps eliminate the ill-affects of paranoia. Other kinds can be detrimental to peace, such as China's many successful attempts at acquiring U.S. military technological and operational information.

Nothing more powerfully engages students than video games. It's just be very difficult finding ways to exploit this for educational purposes without destroying that affect in the process. My own best idea on the holy grail of a truly addictive game useful for very general and comprehensive educational purposes is an RTS game from an FPS perspective beginning the neolithic times, in a persistent world. A student would begin as a primitive man and gradually work his way toward inventing all the technologies of the modern world in building his civilization. He'd invent each tool by learning the physics and usefulness of it. Then he could add it to the village he founds to expand it. The village and eventual civilization would be, along with its annals, would be a e-portfolio (why the world needs to be persistent, not starting fresh each time the student logs on--he must always be building upon the foundations already established). The student would design the economic system, etc. and his "subjects" would follow the rules he stipulates. He could trade with the villages of others for items he might need to get ahead but cannot produce them himself until he learns the principles behind the technology. The population might be given needs also for entertainment, thus poetry, etc. for a more pacified people. Many ideas can be added within this framework. It's a student's own world in which he can feel safe and for which he should develop more interest as it continue to operation even when he is offline (to increase engagement). And being multiplayer can also provide the social aspect and teamwork for shared goals.... like say, building a trading route and defending it from bandits, investing materials for construction of a dam and irrigation... etc. I have a basic design to build the infrastructure for this. There wouldn't by chance be any grants out there that might apply?

I really like this game idea. Seems like it would be a monster of an undertaking not just for the game engine itself, but more so for the content. Let me know if you get this one off the ground.

I realized while writing this that it would be difficult to for education professionals to understand this concept. I should have known Shirey would get it. After so much experience in software, one starts to see two personality types--those who design software from a philosophical perspective and those who do so from an immediate, practical point of view. The philosophicals enjoy designing and writing new kinds of software. They are also the kind of people who tend to enjoy RTS games. The immediates struggle trying to write software from scratch, except for where they understand some pre-known framework for writing software of the particular class. They are more often relegated to debugging and tweaking software. These people tend to prefer FPS games. Systems administrators tend to fall more into this category, as well. It's a good complement, I think. I design and they maintain. Philosophicals tend not to be such good maintainers. Immediates tend to make good systems administrators, too. What this all suggests to me is that the only way non-philosophicals (the particular type I mean--don't use the term too generally) are unlikely to "get" the concept until the can see and use it. I would love to be proven wrong. I designed a framework that I think would make building it not so difficult or time consuming. But yes, building content is a chore. Therefore, the way I designed the framework is to allow run-time additions and modifications. That is, you can start simple and gradually add content over time. I think this makes sense in any case because as knowledge changes, so should educational content. Educational methods may also evolve. So I think it is very important that the mechanism for adding and editing be as easy to use as possible. This is where you want the input of non-software engineers.....even non-gamers.

This is about games to improve employee work.

This is about using online games to engage employees in work. This is very much the core of what I was talking about, except for education. For those more knowledgeable about software design: my thoughts so far were on using Google's V8 Javascript engine and a 3D engine, such as Ogre3D, perhaps wrapped by QT or SDL. The worlds would be managed on the server but code for each object type shipped to the clients and run, sychronized there. Everything would be an "object"--even a world itself (a container object). Each object would comprise of four code modules plus its media files (3D models, sounds, etc.): Affector -- this receives sensory input then filters and translates that to the object's internal properties. Intrinsor -- this is the object's behavioral programming. For example, it can be the functions of an espresso machine object or the AI and/or user-interface connector of an animate object, etc. Mitigator -- this is the code that controls the internal environment of any objects contained within this object. It mitigates the effects of contained objects to the affects of others. For example, a world object, a boat, a house, or a bag. The physics, weather, and such will depend on what they are contained within. The mitigator may also initiate effects to contained objects. Effector -- this provides the API for action attempts to the Intrinsor. It then filters and translates the action attempts to the objects actual action attempts that are read by this object's containor. (Yes--I mispelled some words above intentionally) This design provides a framework for a persistent world of decent individual performance. The V8 engine compiles to fast machine code (and caches). Only very minimal data need be communicated over the network. Objects can run in parallel precisely the same, so if a client fails the system continues. Updates of virtually any kind can be made on-the-fly without stopping the game. New object types will be relatively easy to b

FYI, Toulmin was the primary influence on the first WSU Critical Thinking Rubric. (Carella was the other philosopher.)
