The life of a teachers assistant is filled with anxiety,
blank stares and a certain appreciation for what teachers have to put up with.
For a year, I aided in the learning and practice of building circuits.
Introduction to Engineering Electronics at Rensselaer Polytechnic Institute in
New York could be one of the best 1-credit pass/fail courses, but because of
the lack of credit hours, it was refused to be taught another year.
I became the lead TA (teachers assistant) with open arms. I
would meet with the professor every Sunday and I would review material in the
lab section of the class and help them build circuits. The benefit of this
class was that the students could learn from other students, having multiple
methods to being taught the same information. I was in my second year at the
time and it was overwhelming to teach students, some of them having a broader
background in the concepts I was teaching than I did.
The room was equipped with the best lab machines. When I say
best, I don't necessarily mean brand new. By best I mean actual analog
equipment with all the knobs and connectors, the only digitized parts were the
screens. Ten stations were set up with an oscilloscope (without auto-scaling –
much to the dismay of older students who use such technology), multimeter, two
power supplies and a function generator.
These instruments are fundamental to learning. Every week
students would have to examine a waveform on the oscilloscope. Using the knobs
and switches gave students a better understanding of how the scaling works and
what certain terminology means. These bench-top instruments are beginning to
transfer to digital.
Part two of this series will run tomorrow (Wednesday). Be sure to stay tuned to find out which of the five senses are
necessary to be a successful teachers assistant in an electrical laboratory.
