Moral Psychology: The Cognitive Science of Morality: Intuition and Diversity (Bradford Books) (Volume 2) (9780262693578): Walter Sinnott-Armstrong: Books Make It Stick — Peter C. Brown, Henry L. Roediger III, Mark A. McDaniel To most of us, learning something “the hard way” implies wasted time and effort. Good teaching, we believe, should be creatively tailored to the different learning styles of students and should use strategies that make learning easier. Make It Stick turns fashionable ideas like these on their head. Drawing on recent discoveries in cognitive psychology and other disciplines, the authors offer concrete techniques for becoming more productive learners. Memory plays a central role in our ability to carry out complex cognitive tasks, such as applying knowledge to problems never before encountered and drawing inferences from facts already known. Many common study habits and practice routines turn out to be counterproductive.
Maxwell's Equations. From Einstein Light Maxwell's equations: symmetric form Although the equations are simple, they are notated in a few different ways, for use in different circumstances. The variable quantities are the electric field E (written in bold here to indicate that it is a vector), the magnetic field B, the electric charge density ρ (the amount of charge per unit volume) and the electric current density J (the amount of electric current flowing through unit area). There are also properties of the medium, even if it is vacuum. ε is the dielectric permittivity. It is a property of a medium that determines the strength of the electric field produced by a given electric charge and geometry. Greater values of ε mean that more charge is required to produce the same electric field (for all materials in the liquid or solid phase, ε is greater than the vacuum value). μ is the magnetic permeability of a medium. Isn't that lovely?
The Wrong Way to Teach Grammar - Michelle Navarre Cleary A century of research shows that traditional grammar lessons—those hours spent diagramming sentences and memorizing parts of speech—don’t help and may even hinder students’ efforts to become better writers. Yes, they need to learn grammar, but the old-fashioned way does not work. There is a real cost to ignoring such findings. In my work with adults who dropped out of school before earning a college degree, I have found over and over again that they over-edit themselves from the moment they sit down to write. They report thoughts like “Is this right? These students are victims of the mistaken belief that grammar lessons must come before writing, rather than grammar being something that is best learned through writing. Happily, there are solutions. There are also less immediately apparent costs to having generations of learners who associate writing only with correctness.
8 Reasons The IQ Is Meaningless Humans The average person has an intelligence quotient of 100. An unsourced claim gives O. J. The first standardized attempt to measure the human’s mental capacity was courtesy of Alfred Binet and Theodore Simon, who formulated a test to measure verbal ability. Once an average person reaches the age of 15 or so, the IQ test is no longer important, since the mental age has reached maturity. Extremely high scores are routinely inaccurate. 180 on the Standford-Binet is typically the top of the scale, and anything measured over it has few precedents for comparison and should be taken with a grain of salt. All the various tests can do is discover the very low scorers among children, and these scores are quite accurate. Quite a few IQ tests measure “general knowledge.” As general knowledge goes, the intent is to ask questions to which everyone on Earth, at an age of 5, should know the answers. IQ tests were invented for the purpose of scoring children. Children are mean. Close
Study: You Really Can 'Work Smarter, Not Harder' - Nanette Fondas Research shows that reflecting after learning something new makes it stick in your brain. This Year's Love/Flickr Two weeks ago, my oldest son taught my youngest son how to perform a corner kick during half time of my middle son’s soccer game. Learning is more effective if a lesson or experience is deliberately coupled with time spent thinking about what was just presented, a new study shows. In the lab portion of the study, participants completed a math brain teaser under time pressure and wrote about what strategy they used or might use in the future to solve the problem. The study also tested the adage that the best way to learn something is to teach it. For younger students, teaching someone else is a good way to practice synthesizing content after a lesson.

Knocked out in bar fight, man wakes up as a genius TACOMA, Wash. -- Fate has no place in mathematics, yet fate played a role for Jason Padgett and his new fame for being a mathematical genius. Growing up in school, math played no role for Padgett. "I was one of those kids that said, 'When are you going to use math and how can that apply in the real world?'" "They got in a full run behind me and hit me in the back of the head," Padgett said. Doctors told him he had suffered a severe concussion and had some kidney damage from getting beat up. "I see things differently, I started seeing things as pixels, small squares, like the kind that would make up a TV screen," said Padgett, who spent years of therapy adjusting to what was happening to him. He began suffering from PTSD and became OCD as result of the injuries and this new mental state he was felling. He would see life as if it was being presented to him in a grid -- lines and all.
