A US Federal Appeals Court rejects software patents unless "if the math in question complicated enough that "as a practical matter, the use of a computer is required" to perform the calculations"

When the great mathematician Isaac Newton explained the colours of the rainbow with refraction the poet John Keats was horrified. Keats complained (through poetry of course) that a mathematical explanation robbed these marvels of nature of their magic, conquering "all mysteries by rule and line". But as we will see, the mathematical explanation, requiring just the basic geometry of lines and circles, is just as elegant as the rainbows themselves.

From the abstract: :The first aim of this discussion is to suggest a framework for designing serious games based on game features in commercial games, opinions of fourth graders and their teachers, literary studies, contemporary learning theories, as well as successful and unsuccessful similar endeavours. The second part of this paper describes a concrete example of a maths game based on the proposed framework that implicitly tests math and collaboration skills. The game is made of three components: the game itself, a social network, and a teacher reporting tool. Despite a growing interest in GBL, some teachers are reluctant to use serious games in school. To increase usage of serious games as resource, it is important to equip teachers with information and address their concerns. The paper concludes with the idea that serious games need to be designed well in order to provide the immersion and collaborative active learning that most learning theories recommend."

During the live online event Saturday January 14th 2pm ET, Shad Moarif, the founder of Karismath, will lead brainstorming about mathematical videos and dynamic mathematics in general. Event challenge! What types of the Grid do you see from the pedagogical perspective?

Shad is exploring ways of breaking this connection down into a sequence of transitional steps by distilling them visually. Shad has categorized the Grid into eleven types according to their uses for storing, sorting, and displaying numerical information (see below). What pedagogical types of the Grid come to your mind?

Abstract "This article reports on a case study of the web-based educational maths application, Mathletics. The findings are drawn from an ethnographic study of children's technology use in Melbourne, Australia. We explore the experience, governance and commerce of children's Mathletics use, and offer insights into the developing possibilities and challenges emerging through the adoption of Web 2.0 applications for learning and education."

"A research team led by Carnegie Mellon University's Robert Siegler has identified a major source of the gap -- U. S. students' inadequate knowledge of fractions and division. Although fractions and division are taught in elementary school, even many college students have poor knowledge of them. The research team found that fifth graders' understanding of fractions and division predicted high school students' knowledge of algebra and overall math achievement, even after statistically controlling for parents' education and income and for the children's own age, gender, I.Q., reading comprehension, working memory, and knowledge of whole number addition, subtraction and multiplication. Published in Psychological Science, the findings demonstrate an immediate need to improve teaching and learning of fractions and division."

This site features a math category, math concepts explained informed by the principle that "math is no about equations than poetry is about spelling .. .[but exist] to convey an idea."

It would be interesting to build a set a links to similar research results as this and discuss the implications this has for what we do as math teachers in our classrooms.

New research from Vanderbilt University has found students benefit more from being taught the concepts behind math problems rather than the exact procedures to solve the problems. The findings offer teachers new insights on how best to shape math instruction to have the greatest impact on student learning.

This just confirms what all the other research has been saying. The issue is getting all of us who didn't learn math conceptually, and who were not trained in college conceptually, to teach this way.

This multimedia resource includes interactive math activities, print activities, learning strategies, and videos that illustrate how math is used in everyday life. The resource addresses the following mathematics topics: Fractions; Integers; Percentages; Rate/Ratio/Proportion; Square Roots; Exponents; Patterns; Algebra; Linear Equations; Polynomials; Angles; Circles; Surface Area and Volume; Area and Perimeter; Triangles; Pythagoras; Trigonometry; Similarity and Congruence; Transformations; Shape Classification; Data Display and Graphs; Central Tendency and Distribution; and Probability.

A great general maths site with lots of tutorials, activities and games which will help your students at school and at home. http://ictmagic.wikispaces.com/Maths
