Intereitng comment from someone who hides behind the name "someone". Is there a reason you don't use your real name? At least I use my real name and have told you where I teach and live. Any reason you fail to do the same?
Silly "someone", I'm teaching at a public college my name, teaching qualification and where I teach are all a metter of public recored.
If you would stop bashing teahcers you would find I am an award winning instructor and two of my students have been recogined for their acheivments (what I taught them) by the Preseidnt of the United States.
Can you say the same? Or are you one of those people that just goes arond basing teachers who do a good job?
'Doug' your comment above has to be some sort of record here at this forum for sudden grammar gone south
Sorry to be 'that guy' to point it out, but just look at it
Did somebody accidently spill vodka or grappa onto the keyboard while the speech recognition program was running?
You do have a valid point. My reply was written on a small screen device, with a funky auto-correct/spell checker while I was driving my car. To pay homage to Mark Twain.... I’m sorry I did not have the time to make my post shorter of correct the spelling pr grammar.
But here’s the think... does it really matter? “Someone” has become a troll and has an agenda which apparently included bashing instructors and has nothing to do with the original post or subsequent questions. If “someone” were posting serious meaningful posts I would take the take to provide grammatically correct responses.
I will say this again, I really would like to thank those whol provided meaningful quality responses to my original question. I might be an instructor/profesor but I tool am always learning. Most of the folks here have given me wonderfull information which I’ve already used in my classroom and on conference calls with other instructors so they will teach their studnets.
As i stated previously it’s been decades since I have used a scope so being a buy one to use as a demonstration device in the classroom will be a real treat for my studnets. I teach computer networking so now I will be able to show my studnets the actual network signals and even decode one or two.
What “someone” may not understand is when one works with networking equipment one is not always working with low voltages. Studnets are working wth 48 vdc and mains or 120/208 and 220vac.
For the past 20 years the $8,00 eBay multimeters have been fine. (Although someone is telling me they aren’t safe and one my studnets is going to get killed). Well that has not happened. In all my years of teaching I have never had even one student get seriously injured. Worst injury is getting poked with a screwdriver, getting pinched with a pair of pliers or getting zapped. I think the worst injury I have seen in 25 years in a technology class is a paper cut. Now I’m sure someone is going to say I’m irresponsible for using paper in my class and that a studnet could die form getting cut and infected. Yes that is possible and I am sure it happens but the reality is many of these kids if they were not in school would be doing other things more risky LSU he as stealing copper wire from street lights in our campus parking lot. (Yup, that has happed 3 times so far). At least if they take my class they will be able to use a voltage probe and multimeter to test the wire to see if it is energized befor they cut it. I think this would make someone happy knowing I might be saving the life of a thief who is stealing copper wire.
