Well, at least it's good to know it's not just me. I've been teaching

Physics for 30 some years now, and have never needed more than a

calculator with trig functions, yet all my students are required by an

engineering prof. to buy graphing calculators. Never mind that they're

clueless as to how to store a value in memory, etc. My "Required

Materials" list has been amended from including "a calculator with

trigonometric functions" to "a calculator with trigonometric functions

and knowledge of how to use it". I didn't used to set homework in lab (3

hrs in lab for 1 credit hour seemed enough.) These days though I set

uncertainty calculations as homework, and each student has to get a

homework perfectly correct before they pass my lab. If they don't get it

right, they get handed another. I haven't had to flunk anyone yet, but

I've had students get to HW#8 before getting it right. The upside is

that exams scores improved significantly after this "zero mistakes

tolerated" procedure was adopted,

cheers,

David

P.S. and I'm sick of them pulling out a calculator to find out what 7X8

equals................
