The Texas Instrument CBRs (calculator based sonic rangers) have
been great.
They only need a TI-8x graphing calculator, so no need to hook up
the CBLs. Our experience with the TI-83 has been great. Most new
users (including teachers) seem to pick-up the operation quickly.
I would still want CBLs for other experiments.
< Our resourceful tech people just acquired a $70,000 grant for
"science
< laboratory technology" to be shared by our HS and Jr High
science
< departments here in Chartucky. A large chunk of that change will
go for
< laptop PC's, as we have no realistic way of accomodating desktop
models.
< Most of the rest we want to put into calculator-based and
computer-based
< interfaces, probes, detectors.
<
< Obviously we would like to get the biggest bang for the buck.
What has
< worked best for you folks that already have this technology in your
labs?
< We are looking at TI-8x CBL stuff and at Vernier's stuff; would that
be
< money well-spent? Pasco? What is the equipment you just
couldn't live
< without?
