Study of two Indian tribes, one a partilineal society, the other matrilineal, to discover ability to solve a spatial reasoning task

"experiment performed by Loukas Balafoutas and Matthias Sutter, released February 2 by Science, involved three methods that provided an initial advantage to women in a math competition. The authors found that, in each case, women entered the competitions more readily, but the aggregate performance of the participants was unaffected, and sometimes even improved."

Researchers from Notre Dame and Harvard, in a paper to be published in the Quarterly Journal of Economics, discuss Soviet mathematicians' movement to U.S. institutions following the breakup of the Soviet Union, how Soviet mathematical study engaged in different areas of specialization from that of the west, and subsequently "a flood of new mathematicians, theorems and ideas."

Video games are hard, and that's official Super Mario, Donkey Kong and other classic games belong to class of hard mathematical puzzles, and could be used to solve real-world problems IF YOU have ever struggled to complete classic Nintendo games, don't feel bad?- they are officially difficult.

Abstract: Educational videogames can be designed to provide instructional feedback that is responsive to specific actions. However, existing research indicates that students tend to ignore videogame feedback and subsequently use less effective help-seeking strategies. Research on help-seeking in learning environments has primarily focused on the role of cognitive factors, the nature of the help, or issues of timing and frequency. There is a noticeable gap in understanding regarding how to motivate and increase the use of feedback for improved learning. Using a pre-algebra videogame, this study examined the relationship between an incentive to use feedback and math achievement. A randomized-control design was employed, which compared learning outcomes of students who received the incentive to those who did not. Results indicated that students given the incentive to use feedback had significantly higher normalized change scores on math items (d = .53), with stronger effects for students with low academic intrinsic motivation (d = .88 - 1.17).

Abstract "The relation between fidelity of implementation and student outcomes in a computer-based middle school mathematics curriculum was measured empirically. Participants included 485 students and 23 teachers from 11 public middle schools across seven states. Implementation fidelity was defined using two constructs: fidelity to structure and fidelity to process".

"SRI International, Worcester Polytechnic Institute (WPI), and the University of Maine have received a $3.5 million award from the Institute of Education Sciences at the U.S. Department of Education to evaluate the effectiveness of an online tutoring system for mathematics homework. The research team will study seventh-grade mathematics students and teachers in more than 50 schools throughout Maine using WPI's ASSISTments system. ASSISTments aims to transform homework by giving students instant feedback and tutoring adapted to their individual needs. It also provides teachers with customized reports each morning on their students' nightly progress. Teachers in the study will receive training in how to use these reports to adapt their lesson plans to better suit students' needs."

There are plenty of calculator apps in Google Play, but IDEAL WebMath is different because it shows students how to solve a problem.  IDEAL WebMath can help students with addition, subtraction, multiplication, division, comparing fractions, ratios, proportions, place values, and rounding.

"Among mathematicians, it is always a happy moment when a long-standing problem is suddenly solved. The year 2012 started with such a moment, when an Irish mathematician named Gary McGuire announced a solution to the minimal-clue problem for Sudoku puzzles." Article written by author of a recent book, "Taking Sudoku Seriously: The Math Behind the World's Most Popular Pencil Puzzle".

Review of 1999 book on cosmology demonstrating universal phenomena contingent on six numbers. "Forget those 1,000 things you need to do before you die, the 10 commandments and seven deadly sins. Concentrate instead on six impossible things that, as the White Queen advised Alice, you must try to believe before breakfast. Without them there would be no galaxies of stars, no chemistry, no people, no books and no breakfast."
