The Powder Keg of Awesome!

Enjoyed chatting yesterday with Jerry Kennedy and Jackie Dotson on the 50th episode of The Powder Keg of Awesome radio program. We got into a range of topics including a.) the psychology of certain presidential candidates; b.) navigating the "space between" in educational curricula and c.) being non-linear in an otherwise linear world and many more topics that lack descriptive words.

Game Based Learning for Social Studies Teachers

The Global Challenge Project is a proprietary "game-based" educational program which has been tested with positive effects for nearly a decade in high school-level World History and U.S. Government courses. Though the game was designed as a new way to teach world history, it also covers geography and government and helps students to learn teamwork and understand the principles of money management.

Quick preview of the presentation by one of the many speakers to present tomorrow in Sacramento.
Many of today's youth spend their time in Internet-based virtual worlds like Second Life or in role-playing games like Final Fantasy and World of Warcraft.  What is this doing to their brains? Alex Terrazas, President and Chief Scientist at Media Balance, addresses this question through a discussion of his research on the hippocampus (the brain area critical to cognitive mapping).  He says that by living in virtual worlds and relying on technology like GPS devices, we may be letting the hippocampus out of its usual job of mapping events to their locations. The question is, what is the hippocampus going to be used for now?

Can exercise improve cognitive function?

The date of the article is November, 2007 - but the evidence seems strong that exercise improves cognitive function - and it is doubtful that it has been overturned.

According to the authors (see below):  "In people, fitness training slows the age-related shrinkage of the frontal cortex, which is important for executive function. In rodents, exercise increases the number of capillaries in the brain, which should improve blood flow, and therefore the availability of energy, to neurons. Exercise may also help the brain by improving cardiovascular health, preventing heart attacks and strokes that can cause brain damage. Finally, exercise causes the release of growth factors, proteins that increase the number of connections between neurons, and the birth of neurons in the hippocampus, a brain region important for memory. Any of these effects might improve cognitive performance, though it’s not known which ones are most important."
