Rowling. http://www.mathetude.com:80/story/view/15452.html http://www.mathetude.com:80/story/view/15452.html Mathetude MrGreen 14/05/2012 The William and Flora Hewlett Foundation announced the winners of its Automated Student Assessment Prize, or ASAP, essay grading competition on Wednesday, after issuing a report last month that found automated essay-graders capable of replicating scores of their human counterparts. http://www.mathetude.com:80/story/view/15420.html http://www.mathetude.com:80/story/view/15420.html Mathetude MrGreen 11/05/2012 There's a ton of conversation swirling around how principal evaluations should look in the future—but how do school leader evaluations look right now? http://www.mathetude.com:80/story/view/15419.html http://www.mathetude.com:80/story/view/15419.html Mathetude MrGreen 11/05/2012 The National Assessment Governing Board released findings Thursday morning on earth, life, and physical sciences mastery on the National Assessment of Educational Progress, or NAEP. The average 8th grade score rose from 150 in 2009 to 152 last year; that’s a statistically significant increase, but still well below 170, science proficiency on the test’s 300-point scale. http://www.mathetude.com:80/story/view/15418.html http://www.mathetude.com:80/story/view/15418.html Mathetude MrGreen 11/05/2012 This problem provides a purpose for practicing the routine algebraic procedure of expanding brackets. For students who are unfamiliar with algebra, this problem is an excellent context for observing, conjecturing and thinking about proof. It can be a good introduction to the power of algebra, and to a related geometrical interpretation. http://www.mathetude.com:80/story/view/15417.html http://www.mathetude.com:80/story/view/15417.html Mathetude MrGreen 10/05/2012 This problem introduces students to the concept of different categories of real functions which permeate advanced mathematics. It focuses on understanding the properties of the categories as a whole rather than the properties of individual examples. Hopefully students will leave with the realization that smooth functions are a very special group of functions along with a wider understanding of functions, continuity and differentiability. http://www.mathetude.com:80/story/view/15416.html http://www.mathetude.com:80/story/view/15416.html Mathetude MrGreen 10/05/2012 When students meet polar coordinates for the first time, they are sometimes reluctant to engage with a new representation when they can already do so much with the powerful cartesian representation to which they are accustomed. This problem defines polar coordinates through the familiar idea of specifying a location using a bearing and a distance, and then offers students the opportunity to reflect on occasions when the polar representation might be better suited than the cartesian. http://www.mathetude.com:80/story/view/15415.html http://www.mathetude.com:80/story/view/15415.html Mathetude MrGreen 10/05/2012 This problem introduces students to different definitions or representations of trigonometric functions and challenges them to consider when each different representation is most useful. http://www.mathetude.com:80/story/view/15414.html http://www.mathetude.com:80/story/view/15414.html Mathetude MrGreen 10/05/2012 Children sometimes think there is only one representation of fractions; usually pizzas or cake slices! This game is designed to help children see fractions in many different ways: by looking at a range of images of one fraction they can begin to develop a deeper understanding of what a fraction is. http://www.mathetude.com:80/story/view/15413.html http://www.mathetude.com:80/story/view/15413.html Mathetude MrGreen 10/05/2012 This problem is designed to help children see numbers in many different ways. This can help them to develop the abstract idea of the numbers. This is sometimes known as "the two-ness of two". http://www.mathetude.com:80/story/view/15412.html http://www.mathetude.com:80/story/view/15412.html Mathetude MrGreen 10/05/2012
