I just got back from three awesome days at the Annual CUE Conference in Palm Springs. Sessions I attended:Applying Best Practices in 1:1 (Cheryl Morris, Andrew Thomasson, Sam Patterson)Slide Deck (see for lots of student creation examples)Students have a digital portfolio on WeeblyAutocrat can let students fill out a form and be emailed a document; teacher is still owner (still not sure how this is better/easier than Doctopus; need to explore)Pixlr functions like photoshop (14.99/year for

infinity-imagined:This animation shows a human brain in cross-section. A head was frozen in a block of ice, sectioned with a macrotome, and photographed repeatedly. 700 horizontal sections with a thickness of 174 microns were produced and imaged. The animation starts near the top of the head and proceeds down towards the neck, then reverses and returns to the top.Images produced by the Visible Human Project, National Library of Medicine; http://vhnet.nlm.nih.gov/

The lessons we learned from the Ryu-Takayanagi formula, the firewall paradox and the ER=EPR conjecture have convinced us that quantum information theory can become a powerful tool to sharpen our understanding of various problems in high-energy physics. But, many of … Continue reading →

The Norwegian Academy of Sciences and Letters has announced that the Abel Prize for 2015 will go to American mathematicians John F. Nash, Jr. and Louis Nirenberg “for striking and seminal contributions to the theory of nonlinear partial differential equations and its applications to geometric analysis.” Read full details on the Abel Prize website. by

The golden ratio is greatly hyped, partly for its beautiful mathematical properties but also for nonsensical reasons. Distinguishing between the two requires understanding that mathematics is about structures and relationships, not just numbers in isolation.

the diagram is, essentially, traced from bruce e.~meserve’s _fundamental_concepts_- _of_geometry_ (dover reprint of 1983; originally addison-wesley 1959). but i added in the colors. with which, one has as follows. there’s a red line, a blue line, and a yellow line. to start with. all sharing a point. then two “triangles” are constructed: each of these […]

My older son and I are currently studying how angles and circles interact. I though that a good way for him to review some of the basic properties would be to give a short, sort of mini lecture on three of the properties. First up, what happens when the angle is on the circle: Next…

Another post from Tap Into Teen Minds. Enjoy!
There are two groups of students I used to see forming in my math classroom and my teaching & assessment practices were the main reason why they formed.
