And this is supposedly the advanced class??? [seethes with rage] I missed that before posting my previous comment. x10 to everything I said in that post. Un-freakin-believable. Disgusting.
Top shelf teacher, excellent results borne out by nearly every CalcAB and every CalcCD student scoring a “5” on the AP test. The students really do master the material. So the problem is really a narrow one. Our local school district’s high school math administrator and the high school math teachers have simplified things for themselves, not that they will admit it. No teacher will take a single step to encourage the use of Reverse Polish Notation. They will NOT tell you that you and your student will sorely regret buying a high-end HP calculator (for about $145). But your kid WILL pay the price, almost as if being taught in German and having to translate everything on the fly into French (and suffering the attendant exhaustion). And though you may wish to continue to “fight the power” you WILL end up putting the HP in a drawer, knuckling under, and heading out on a lonely Sunday night in October to buy a TI n-spire CX or a TI n-spire CX CAS calculator for $160.00, only to find that nobody has any in stock (sold out).
