Every student regardless of ability goes through the same sequence. Then it's off to algebra at which time the kids get tracked. Nonetheless, they all learn algebra, some just go a bit deeper than others.<BR/><BR/>Here are the <A HREF="http://www.singaporemath.com/Placement_Test_s/86.htm" REL="nofollow">placement exams</A>. They are no walk in the park.<BR/><BR/>You really shouldn't need a math degree to teach elementary math. But when schools fail to teach math properly at the K-12 level anyone without a math degree tends not to know enough math to be able to teach basic math effectively.KDeRosahttps://www.blogger.com/profile/06853211164976890091noreply@blogger.comtag:blogger.com,1999:blog-25541994.post-1158607805335210682006-09-18T15:30:00.000-04:002006-09-18T15:30:00.000-04:00The problem with the traditional textbooks is that...The problem with the traditional textbooks is that too many students were not mastering math. Sure, they were great for that top 20% of the class. That group learns using pretty much anything. The bar is set low.<BR/><BR/>I think, however, that these traditional books were not written with the average math student in mind, not to mention the lower performers. These kids need the concepts broken down a bit more finely and they need much more practice than the traditional textbooks provide before they will understand and retain the material.<BR/><BR/>We've learned a lot since the old traditional textbooks were in common usage. Singapore Math, Saxon, and CMC all represent improvements on traditional math.KDeRosahttps://www.blogger.com/profile/06853211164976890091noreply@blogger.comtag:blogger.com,1999:blog-25541994.post-1158607185130144512006-09-18T15:19:00.000-04:002006-09-18T15:19:00.000-04:00I think I am going to scan a few pages of my kids ...I think I am going to scan a few pages of my kids 3rd grade math text books next time they bring them home. Its all bright and cheeful... has lots of fun little facts... and not bogged down with all those bothersome numbers and problems.<BR/><BR/>One question. I was under the impression that Singapore math was mostly concentrated at the elementary and middle school levels? At least in elementary school, surely even the typical liberal arts degree teacher should be able to teach the level of math required at this age. Middle schools and high schools would be the ones that would really need the qualified teachers. Unfortunately, teachers are paid well compared to college graduates with liberal arts degrees, but are poorly paid compared to graduates with engineering, science and math degrees. There needs to be more flexibility to pay people comparative with their skills, instead of the one pay scale fits all. I would love to be a math teacher, but the average starting salary here for a new teacher with a math degree is around $30,000. If I was willing to accept that amount of money, I might as well just get a degree in basket weaving.roryhttps://www.blogger.com/profile/07402069244849123343noreply@blogger.comtag:blogger.com,1999:blog-25541994.post-1158606099516810812006-09-18T15:01:00.000-04:002006-09-18T15:01:00.000-04:00when, and why, did the curriculum move backI belie...<I>when, and why, did the curriculum move back</I><BR/><BR/>I believe the answer is the early 90s in response to the NCTM's original math standards. Though certainly trouble was afoot before that.<BR/><BR/>I went to a Catholic high school in the early 80s which offered two years of Latin and a year of Greek. Latin was clerly on the wane, though; only six students were in my Latin II class. I transferred in my mid-Junior year to another Catholic high school that did not offer Latin -- so I only wound up with a year and a quarter under my belt.KDeRosahttps://www.blogger.com/profile/06853211164976890091noreply@blogger.comtag:blogger.com,1999:blog-25541994.post-1158602253795951112006-09-18T13:57:00.000-04:002006-09-18T13:57:00.000-04:00Why rewrite the textbooks?

In my high school (grades 9-12), the college prep math track was Algebra I, Geometry, Algebra II/, Introductory Calculus, with trig spread across the junior and senior years. I suppose a lot of what we did in junior high could be called algebra, at least pre-algebra math.<BR/><BR/>I was, btw, the last class in our high school who were able to take two years of Latin (they were just phasing Latin out nationally).Anonymousnoreply@blogger.com
