Thus, it does include classwork; there is also a separate grade awarded each term for oral participation in class. So teacher-pleasing behavior and homework completion are significant components of the Abitur.<br /><br />Theodore Dalrympole pointed out in 2005 that the French Bac's rigor has been significantly diluted: <i>French educational certificates have undergone the same grade inflation as British ones: for example, the proportion of children who pass their bac nowadays is more than five times what it was in 1970. In other words, the bac is not the guarantee of ability and accomplishment that it once was, and employers must make their choices on other grounds than a debased certification.</i>. http://www.socialaffairsunit.org.uk/blog/archives/000669.phpCranberrynoreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-2241354302798624862014-07-23T15:05:28.936-04:002014-07-23T15:05:28.936-04:00I can't resist commenting that no part of the ...I can't resist commenting that no part of the curriculum is under more continual threat here in England than A-levels. They are absolutely hated by the educational establishment who would much rather have a broader diploma, perhaps including more vocational elements, than have A-levels as the "gold standard" for university admission.

But here's my take: when it comes to mathematics, (or, for that matter, engineering, accounting, pharmaceuticals, surgery, piloting airplanes, operating machinery, or, dare I even say it, educating our children), "wanting to know which way is right" is a pretty reasonable desire--especially when it comes to one of the Common Core's main obsessions: all those "real-life situations." '</i><br /><br />In engineering,it is important to recognize when a method is correct, but it is also very important to realize that there is not just one way that is right. Indeed, engineering is all about finding right ways to solve problems, and there are few design problems that have only one solution. Students who are locked into "finding <i>the</i> answer" make poor designers and engineers. <br /><br />And engineers do need to learn how to write up their designs and their mathematics in a way that makes it clear that they have done it correctly. So the goals of Common Core are good at heart.<br /><br />But…<br /><br />There is little to write about mathematics in a meaningful way at the level of elementary school students, and even few high school teachers can tell what is important to write about and what is just drivel from a practical standpoint. So mandating that those who are clueless about what is important to write teach students to write something is unlikely to have a positive outcome.gasstationwithoutpumpshttp://gasstationwithoutpumps.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-3329097928901616502014-07-22T10:56:17.257-04:002014-07-22T10:56:17.257-04:00Shoot me now.

Sometimes the comparisons are quite illuminating. However, today's comparison does not really work. A speed test is very different from a concept-builder. The Everyday Math page looks like a concept builder. However, I completely agree that at some point, the curriculum needs to remember that building concepts is a stepping stone to the ultimate goal of getting right answers (without a calculator).S Goyahttp://www.blogger.com/profile/18373952981169252818noreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-2890541872958195102014-07-17T00:37:24.729-04:002014-07-17T00:37:24.729-04:00This is great.

In the college algebra classes I used to teach, I made a point of showing how, like CT, a minus sign is really a factor of minus 1. I would have students draw circles around each term and each factor of expressions and equations and have them put the negative signs in as factors of the terms. This clears up many problems for them. If the term was a fraction or a rational expression, I would show them how that minus one factor could be put in the numerator or the denominator. Putting a stray minus sign in the middle of a fraction (at the dividing line) was very confusing for them.<br /><br />I would show them that:<br /><br />-3/4 = (-1)(3/4)<br /><br />-3/4 = ((-1)/1)(3/4)<br /><br />-3/4 = ((-1)(3))/4<br /><br />-3/4 = (3)/((-1)(4))<br /><br /><br />How about<br /><br />-3/4 = (3)/((-1)^-1(4))<br /><br />Procedural fluency leads to understanding because fluency implies success and success in all problem variations implies understanding.<br /><br />Algebra II is very hard for students because they have to expand their simple algebraic understandings to ones that can handle the manipulation of any complex situation, as with minus signs. When they try to apply their simple understandings of algebra and fail, many see it as a sign of rote learning and use that to justify all sorts of silly educational ideas.<br />SteveHhttp://www.blogger.com/profile/03956560674752399562noreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-34566215726923808452014-07-15T14:54:02.586-04:002014-07-15T14:54:02.586-04:00I know she was right for the reason you pointed ou...I know she was right for the reason you pointed out.
