I'm currently a sophomore in college. I am
tired of sitting in class, waiting for some
other lackey in class to punch in the simple 3
digit multiplication into his calculator while
the teacher paces back and forth carrying an
eraser waiting for an answer to (3.74*8.21).
I propose a whiteboard
eraser with a small
scientific calculator built into the back side to
allow for quick calculations.

A little epoxy should create this simple useful thing. |
|
| |
agreed, but thats not quite as marketable
as i had envisioned. I'm thinking it would
be recessed into the foam on the back or
the eraser. Why the [-]? |

I think possibly because it's just two widely available items stuck together, despite its possible usefulness. Similar ideas that might not attract buns could include a t-shirt with a clock in it, a mouse-mat with a clock in it, or perhaps a dog, with a clock in it. |

Baked. It's called a watchdog. |

[bleh]: Is it that the teacher doesn't have a calculator and he has to ask someone in the class to provide him with the answer? Lazy bugger! |
|
| |
I'd have a lot more respect for the teacher if they just gave an approximate answer. This would convey the messages that: a) the correct approach to solving a problem is more impotant than the answer itself; and b) being able to approximate the answer before you punch it into a calculator is an important skill. |
|
| |
Ah, but asking a student to do a calculation is a form of audience interaction - rather than genuinely needing a student to do the maths. Admittedly, it might miss the mark as mode of class engagement... |

Agreed on both counts, but as i will not
be attending a *real* college until fall,
i'm stuck with the lazy fools. I've had a
few good teachers who either have
worked the problem out in advance so
they dont have to wait, or will give
approximations. Those are my favorite
teachers. Alas, I am now stuck with a
fool in charge of a chemistry class. |

also agreed, but I think a more valuable
form of engagement is having the class
provide the formula, not the answer to
the maths. |

Absolutely, as long as the teacher/lecturer doesn't use, what I call, "The Assassination" method. One lecturer I used to have would pick on someone to answer a question and then just move to the next person etc. until someone got it. |
|
| |
It would be really embarrassing when he got to the 10th-plus person. He would get incredulous and accuse the class of being lazy and/or idiots. He didn't think for a second it could be because of his crap teaching! |

This is useful only if it's followed by the abbreviation "o.w." - something I use constantly and stands for "or whatever." |
|
| |
We have those digital whiteboards in a lot
of the rooms. Most of the teachers just
write on them with regular markers. I'm
telling you I'm being taught by fools. |

I think of that link often, as I practice my
estimation skills all the time while others
rely on calculators. Its a great idea. |
