How many ways are there to prove the Pythagorean theorem?

Angielski

 

What do Euclid, 12-year-old Einstein, and American President James Garfield have in common? They all came up with elegant proofs for the famous Pythagorean theorem, one of the most fundamental rules of geometry and the basis for practical applications like constructing stable buildings and triangulating GPS coordinates. Betty Fei details these three famous proofs.

The Prisoner’s Dilemma

Angielski

Two perfectly rational gingerbread men, Crispy and Chewy, are out strolling when they’re caught by a fox. Instead of simply eating them, he decides to put their friendship to the test with a cruel dilemma. He’ll ask each gingerbread man whether he’d opt to Spare or Sacrifice the other. What should they choose? Lucas Husted dives into the classic game theory scenario: the Prisoner's Dilemma.

The greatest mathematician that never lived

Angielski

 

When Nicolas Bourbaki applied to the American Mathematical Society in the 1950s, he was already one of the most influential mathematicians of his time. He’d published articles in international journals and his textbooks were required reading. Yet his application was firmly rejected for one simple reason: Nicolas Bourbaki did not exist. How is that possible? Pratik Aghor digs into the mystery.

School Education Gateway published a useful list of European national websites for online and distance learning

All European countries have taken immediate measures to ensure that, although schools have closed during the COVID-19 crisis, teaching and learning can continue. Here we share many of the websites that are used in Member States to provide support and updated information for teachers and school leaders on an ongoing basis.

The Best MOOC Platforms

Angielski

While a certificate from a MOOC isn’t the same as a college degree, MOOCs are providing access to world-class education to anyone with an internet connection, which opens up a world of possibilities. For instance, a high school student can take a MOOC that allows them to determine which career path is right for them (before wasting time and money on a degree that they can’t or don’t want to use). Additionally, those who can’t afford to quit their job to go back to school to further or change their career path can take MOOCs in their free time.

15 Essential Strategies in Teaching Math

Angielski

We all want our kids to succeed in math. In most districts, standardized tests are the way understanding is measured, yet nobody wants to teach to the test. Over-reliance on test prep materials and “drill and kill” worksheets steals instructional time while also harming learning and motivation. But sound instruction and good test scores aren’t mutually exclusive. Being intentional and using creative approaches to your instruction can get students excited about math.
