Re: The Truth about Gender and Math

There was no relation between a teacher’s [level of] math anxiety and her students’ math achievement at the beginning of the school year. By the school year’s end, however, the more anxious teachers were about math, the more likely girls (but not boys) were to endorse the commonly held stereotype t...

Re: Protect children from Obama!

The district I teach in has ordered teachers to not show the live webcast/broadcast or whatever it is. The district will record the speech and make available to taechers the recordings to view and decide what is approriate for their particular class. Mostly a PR CYA kind of solution, but also relati...

Re: Theories on education

It's 9:00... time to be naturally curious about triangles but not big numbers. Stop! It's 9:50... time to go be naturally curious about American literature but not haiku. ... As long as this is the structure of the educational system it seems rather silly to think any style of instruction is going t...

While he does write Sci-Fi exclusively, he is very versatile moving from cyber punk to comedy, hard science fiction to science fantasy, alternative history to modern space opera, and even detective stories set in sci-fi land.

Re: Calculus has me lost

I don't believe you need any trig functions for this problem. Pythagorus and implicit differentiation (noting things that remain constant/have no change) are all that are necessary.

Re: Ten Myths About Canadian Healthcare, Busted

I wish I could find the particulars so I could find a link to this, but I read some time ago about a hospital where some economists (I think?) took a look at the heart attack response procedure.... Malcolm Gladwell wrote about it in Blink (I highly recommend it). A Cook County administrator noticed...

Re: Math bloopers heard in math classes

Not exactly heard...but I will from time to time be working some long trig problem on the board and writing rather quickly when there will be a few chuckles and giggles from the class...looking back at my work I have sadly written sex in place of sec x. ( Hmm... it's much funnier when it happens in ...

Re: Why is the cosecant "co"?

You could feed them some bull about making the pythagorean identities nicer... sin 2 x +cos 2 x = 1 1 + cot 2 x = csc 2 x tan 2 x +1 = sec 2 x Notice how all the co's go together so nicely... You could also spew forth about all of the basic derivatives of sec x, tan x, csc x, cot x being nicer since...

Re: Factoring Binomials

Another variation * on the "it works (provided there is no common factor) just don't worry about the details" that some of my coworkers teach that makes me want to cry and bang my head against the wall. I'll just work through the same example everyone else has been doing: 20x^2-7x-6 Just l...

Re: Ways of making a team

This is a very common mistake many of my students make (and I made when I was a student). A is a boy and 123 are girls. If we try to do a calculation where order matters and then divide by the number of repeats (4! for this case), we need to make sure our method gets all of the arrangments. A123 wil...
