The latter is the manner preferred by Ricardo Nemirovsky, a professor of mathematics education at San Diego State University and director of the Center for Research in Mathematics and Science Education, a joint program involving SDSU and the University of California San Diego. • Admissions requirements: master’s degree in math, biology, or physics or master’s degree in math education and with math courses during Ph.D. • Students serve on a variety of projects including school-based research on learning, pre-service teachers’ knowledge and beliefs, professional development of local teachers and translation projects for the public. The center’s purpose is to study how people learn math and science and then use that research to develop more effective K-12 and college curricula and better train educators to teach those subjects.
Graphing Inequalities « Zero-Knowledge Proofs
November 3, 2011 by John Scammell Last week, I mentioned to a group of teachers that I had never come up with a good way to teach kids where to shade when graphing an inequality. Vicky from one of our local high schools shared her method with me. It’s pretty nice. Vicky gives her students an inequality like She asks them to each find two coordinates that satisfy the inequality, and then plot them on a giant grid at the front of the room.

Earth has been around for awhile. So have humans. Or have we? According to this fascinating new picture I stumbled across on Google+ (via Ahmed Zeeshan ), humans would only represent, wait for it, 1 minute and 17 seconds if the entire Earth’s history was viewed as a 24 hour period. Takeaways: meteorites spent a lot of time bombarding our planet; the Earth took awhile to actually form; coal swamps (seriously, coal swamps?) and basically everything else on the planet, including the planet itself, has been around far longer than human life.
UTC is the new name for what used to be called GMT (Greenwich Mean Time). It is the time in London (where 0 degrees longitude is located) during winter. In summer, London's time is one hour different to UTC time.
World Population - Live Update
When I first started teaching, I would lecture for 30 minutes, and students would work for 60 minutes (I started in with a double block of math) during double block math classes, and in a 45 minute lesson, I would still lecture for 30 minutes, and students would get 15 minutes to practice and do other activities. I discovered early on in my teaching that the less time I talked, the more time students had to work on activities and exercises, and this led to improved understanding. I read research suggesting that adolescents could actively pay attention for about 10 - 15 minutes, so I focused on getting the lecture portion of my lesson down to this length, and on embedding more questions and subsequent discussion into my lecture. Today I tried something new.

You're living in a computer simulation, and math proves it
Is your life really your life, or is it actually the dream of a butterfly? Or is it a complex computer simulation indistinguishable from "real" reality? Don't worry, it's just a glitch in the Matrix.I’ve been collecting some great articles and finally realized how selfish it was that I wasn’t sharing them. So here’re a few: Who doesn’t love Legos?

By Jeffrey R. Young Perci Diaconis, a professor of mathematics and statistics at Stanford University, describes his latest foray into the mathematics of shuffling playing cards—and explains why his research matters.

The Magical Mind of Persi Diaconis - The Chronicle Review - The Chronicle of Higher Education
He was 14 years old and obsessed with magic, spending much of his free time in or around Tannen's Magic Store, on Times Square, where sleight-of-hand masters regularly gathered to show off tricks and to gossip. There, one of the most influential magicians of the past century, a card maestro named Dai Vernon, saw Diaconis's prodigious trick dealing and invited the young man to leave New York and join him on the road. Diaconis vanished from his regular life, dropping out of school and cutting ties with his family.Math Edreform
