A workshop that took place February 14, 2011 to February 16, 2011, facilitating discussion of "what is important about journal publishing to mathematicians," just released its final report.
According to Nancy Kimberly of HASTAC, this set of video games won the 1st National STEM Video Game Challenge: "Numbaland!, produced by graduate students Derek Lomas of Carnegie Mellon University, Dixie Ching of New York University and Jeanine Sun of the University of California at San Diego, was the winner of the Collegiate and Impact Prizes and will receive $50,000 in total. The collection of four games allows children in kindergarten to grade 4 to construct a set of skills that helps develop their sense of number concepts"
This website is K-12 with algebra tiles, fractions and interactive games on the computer. It also has a "grapher" that graphs up to 3 functions. I use it to find x and y-intercepts of lines or parabolas
National Center for Academic Transformation (NCAT) describes the success of the "Emporium Model" in college math teaching with examples of institutions that have put best practices into effect
Prolific science writer Aczel offers a grab bag of biographical sketches of important mathematicians: starting with the "rope-pullers" in ancient Egypt, who determined property lines for farmers
How mathematics affects our daily lives in sociological, economic, and historical perspectives. Three volume set, 490 articles, published in October 2011
"Several of our classes involve students using mathematical expressions, but there was no way for us to automatically check this work. The stated solution to a problem may be x+y, but if a student answers y+x, our system needs to understand that this is also correct." "sympy, an open source Python library for symbolic mathematics," is proposed as a solution.
