If one should develop naturally from students attempting to describe events, I certainly would acknowledge it, but on principal, tricks and gadgets should never replace authentic learning. memorizing these tricks can also interfere with the flexibility of thinking necessary for students to conceptualize math. SOHCAHTOA doesn't help anyone see tan as a height/distance ratio, a slope, a direction, or a secant line. It's more important for students to experience the tangent of an angle and how it's measure is affected by the height distance ratio. To recognize that a Trig ratio is the signature of a unique angle. Really, the only thing students should memorize are benchmarks that will help them solve or reason about other problems; benchmarks such as the tan of 27 or 63, and 45 that help them gauge to magnitude of other angles; relationships that they should reason about the tan of 90 and why m tan 91 is negative.   Mnemonics never hurt me. I learned SOHCAHTOA. But that did nothing to help me, and more importantly, nothing to help my students understand these relationships any better. The mnemonic in fat was a crutch my kids would desperately try to squeeze answers from on exams. Since I changed my pedagogy to a more active learning approach, my students' performance and understanding has soared.             -----Original Message-----         From: channel-talkmathhs-bounces@learner.org [mailto:channel-talkmathhs-bounces@learner.org] On Behalf Of teresa75         Sent: Wednesday, March 24, 2004 5:07 PM         To: conniemarie@cox.net; Discussion list for TEACHING MATH, GRADES 9-12         Subject: Re: [Channel-talkmathhs] mnemonics                           Yes Constance, Ssme can but for others the mnemonics help.

Sin, cos, tan? I myself can never remember all the mnemonics-what if they can't either? These kids can play computer games that'll knock your sock off-can't they recognize a few ratios?                                      _____                 From: channel-talkmathhs-bounces@learner.org [mailto:channel-talkmathhs-bounces@learner.org] On Behalf Of Jennifer Gwilt                 Sent: Wednesday, March 17, 2004 5:04 AM                 To: channel-talkmathhs@learner.org                 Subject: Re: [Channel-talkmathhs] mnemonics                                   A friend told me that they used Sohcahtoa which you pronounce Sock-ah-toe-ah                         ----- Original Message -----                         From: Don Flynn                         Sent: Monday, March 15, 2004 10:22 PM                         Subject: Re: [Channel-talkmathhs] mnemonics                                                   I had learned "Oscar Had A Heap Of Apples" for trig functions sine, cosine and tangent as opposite side, adjacent side and hypotenuse, myself in high school.                                                   Then one student offered "Some Old Hippy Caught Another Hippie Tripping On Acid", which while contrary to our drug use policy at school is very catchy for students.                                                   I tried "Some Obese Heifer Cow Always Had Taken Others Alfalfa" but it wasn't nearly as effective.                                 ----- Original Message -----                                 From: teresa75                                 Sent: Friday, March 12, 2004 4:32 AM                                 Subject: [Channel-talkmathhs] mnemonics                                                                   What are some mnemonics or memory devices that you use in you math classroom? One I came up with for my students is that you have to use the Law of Cosines in SASSy triangles to help them remember SAS and SSS is when the LOC is necessary.                    _____                                  _______________________________________________                 Channel-talkmathhs mailing list                 Channel-talkmathhs@learner.org          http://www.learner.org/mailman/listinfo/channel-talkmathhs                                  You may un-subscribe from this email list at any time by using the online form at the above URL.
