Elizabeth Borneman explores how cartography and cartographic projections help and hinder our perception of the world."How do you think the world (starting with our perceptions) could change if the map looked differently? What if Australia was on top and the hemispheres switched? By changing how we look at a map we truly can begin to explore and change our assumptions about the world we live in."Geography doesn’t just teach us about the Earth; it provides ways for thinking about the Earth that shapes how we see the world. Maps do the same; they represent a version of reality and that influences how we think about places. Tags: mapping, perspective.

Important to help us all understand how we and others see the world.
Using our keyboards saves us lots of precious time, but writing by hand has lots of benefits.
Researchers have shown that children who know how to write by hand learn to read faster. They are also better at retaining information and coming up with new ideas.
“When we write, a unique neural circuit is automatically activated. There is a core recognition of the gesture in the written word, a sort of recognition by mental simulation in your brain,” Stanislas Dehaene, a psychologist at the Collège de France in Paris, told The New York Times.
A study conducted at Indiana University, in the US, reported that when children write by hand three areas of the brain are activated—the left fusiform gyrus, the inferior frontal gyrus and the posterior parietal cortex. These are the same areas that are set in motion when adults read and write. Kids who typed or just traced letters didn’t show any activation in these areas.

Interesting critique of the "Taylor Swift-boating" of today's news.
“ Understanding the basics of the Cognitive Load Theory and applying them to your instructional design is an absolute must, particularly if you want your learners to get the most out of the eLearning course you are creating. This guide will offer you a detailed look at Cognitive Load Theory, including how it can be applied in learning settings. Check the Cognitive Load Theory and Instructional Design article and presentation to find more.”

Important information for maximizing student achievement
Autistic children have an excessive amount of synapses, or brain connections between neurons, which doesn’t alter as it should with age, US scientists have revealed. This could help develop a drug normalizing their number even after diagnosis.
“Chunking is a critical element of the learning process and explains how we can learn and retain increasingly complex information.”
Tom Perran's insight:
This article explains how chunking works and how to apply it in the classroom. Is based on the principle that it's easier to remember small sets of information and a large set. For instance, is it easier to remember 3054269547 or 305–4 26–9547?
"How Sugar Affects the Brain http://bit.ly/1m7zQU3 is a TED-Ed lesson that I stumbled upon this evening while looking for a YouTube video about making sugar glazes (by the way, this is the one I was looking for). In the TED-Ed lesson students learn why sugary foods and beverages can become addictive and how the human body processes sugar."
Recent research suggests that the difficulties dyslexia creates with reading may not be hard-wired. Instead, experience may play a big role in exacerbating reading problems and, potentially, in easing them.
"Have you ever considered letting your students listen to hardcore punk while they take their mid-term exam? Decided to do away with Power Point presentations during your lectures? Urged your students to memorize more in order to remember more? If the answer is no, you may want to rethink your notions of psychology and its place in the learning environment. Here are 35 critical thinking strategies, straight from the mind of Sigmund Freud." | by Sara Briggs

Good strategies to incorporate when planning instruction. (some we already use!)
Researchers develop novel method to image worm brain activity and screen early stage compounds aimed at treating autism and anxiety. A research team at Worcester Polytechnic Institute (WPI) and The Rockefeller University in New York has developed a novel system to image brain activity in multiple awake and unconstrained worms. The technology, which makes it possible to study the genetics and neural circuitry associated with animal behavior, can also be used as a high-throughput screening tool for drug development targeting autism, anxiety, depression, schizophrenia, and other brain disorders. The team details their technology and early results in the paper "High-throughput imaging of neuronal activity in Caenorhabditis elegans," published on-line in advance of print by the journal Proceedings of the National Academy of Sciences . "One of our major objectives is to understand the neural signals that direct behavior—how sensory information is processed through a network of neurons leading to specific decisions and responses," said Dirk Albrecht, PhD, assistant professor of biomedical engineering at WPI and senior author of the paper. Albrecht led the research team both at WPI and at Rockefeller, where he served previously as a postdoctoral researcher in the lab of Cori Bargmann, PhD, a Howard Hughes Medical Institute Investigator and a co-author of the new paper. To study neuronal activity, Albrecht’s lab uses the tiny worm Caenorhabditis elegans (C. elegans), a nematode found in many environments around the world. A typical adult C. elegans is just 1 millimeter long and has 969 cells, of which 302 are neurons. Despite its small size, the worm is a complex organism able to do all of the things animals must do to survive. It can move, eat, mate, and process environmental cues that help it forage for food or react to threats. As a bonus for researchers, C.elegans is transparent. By using various imaging technologies, including optical microscopes, one can literally see into the worm and watch physiological processes in real time. In addition to watching the head neurons light up as they picked up odor cues, the new system can trace signaling through "interneurons." These are pathways that connect external sensors to the rest of the network (the "worm brain") and send signals to muscle cells that adjust the worm's movement based on the cues. Numerous brain disorders in people are believed to arise when neural networks malfunction. In some cases the malfunction is dramatic overreaction to a routine stimulus, while in others it is a lack of appropriate reactions to important cues. Since C. elegans and humans share many of the same genes, discovering genetic causes for differing neuronal responses in worms could be applicable to human physiology. Experimental compounds designed to modulate the action of nerve cells and neuronal networks could be tested first on worms using Albrecht’s new system. The compounds would be infused in the worm arena, along with other stimuli, and the reaction of the worms’ nervous systems could be imaged and analyzed.
