Help Chumly teach 'lectrical!

I took a position teaching Apprentice Electricians at a local institution, as y'all might know.

I wish to move away from the usual blackboard / lectures / standing in front of the class fielding questions kind'a thing, as other instructors here are doing.

I would like to move towards a more interesting overall presentation using more of the senses:

- Blackboard
- Overhead projector
- Flip-charts
- 3D flatbed camera
- PowerPoint & Laptop & wifi fed to ceiling projector
- Music
- Handheld calculator integrated into the presentation
- Mobile printer to generate on-the-fly printouts of parts of the presentation
- Animation of machines, phasors & waveforms via Laptop to wifi to ceiling projector
- Student-held remote controllers for real-time quiz's
- Other stuff

The reason is that in addition to being an Electrician I am a Musician (I have had zero time to play since I started teaching) and I use a lot of high-tech toys in my one-man band. I want to bring that same level of interactive involvement to the students, and I want to use more of the student's five senses to increase the chances for learning. I understand the more senses you involve in the learning process the higher the retention may be.

I figure a decent portion of the presentation part of the lesson plan could end up on the hard drive of the laptop, in concert with a hand held calculator, hand outs, and the other stuff as mentioned above.

I don't mean that I would dismiss the traditional blackboard / lectures / standing in front of the class fielding questions etc but I want to expand on the usual stuff.

Surely this must have already been done with teaching Apprentice Electricians?

Alas, no one at this institution, nor anyone else I have heard of, has done such a thing in this context. I have hopes that some of the more forward thinking institutions may have instructors that have been successful at this.

Here is some of the stuff I teach:

LC resonance
Phasors and vectors
Single phase and three phase theory
Power factor
Electrical code
RLC circuits
Generators and motors
Motor control
Algebra and trigonometry
Inductance and capacitance
AC waveforms
Lighting and power
Transformers
Programmable logic controllers
RC and RL time constants
All sorts of laws from Kirchoff, Watt, Ohm, Faraday etc
Wiring methodology

I teach a lot of math, but it's at the trades level not university physics level, so it's more directly related to actual practices.

We don't get into quantum theory and chemistry etc, plus guys like Newton, although indirectly referenced, are not addressed much, if at all.

So instructors teaching physics / chemistry / atomic theory / complex electronics would have lesson plans not really adhering to where I need to be at the trades level, although some of their stuff would be applicable.

It would be cool if I did not need to filter through reams of PowerPoint data, Pdf files, Word files and Video files etc to extract what I need to teach.

I would appreciate some direct contact information that might help me on my way!

Here is a website from an instructor Socratic Electronics. He seems, from casual observation at least, to have some stuff in common with me, but I gather he is not teaching Apprentice Electricians, he is teaching university level electronics. I could be wrong on this; I've contacted him so we shall see.

In any case, if you good A2K people can hook me up, please let me know either on this thread or by PM.

Chow,

Chum

Listen, if you can just get them to put the black wire on the brass screw and the white wire on the chrome screw and the green wire on the green screw, you will have accomplished a lot.

The most important thing to teach them is this: Never trust that the other person has turned off the breaker. Always test it for yourself. In fact, never take your own word that the electric is off. Test it anyway.

If only it were that simple!

In the US I understand that the scholastic demands put on apprentices is much less, but here in Canada apprenticeships are no less than 4 years and sometimes 5 (as mine was).

Canadian apprentices need 70% to pass, and most of the schooling is in the classroom not with tools. It's fairly in-depth math related to power factor, three phase, RLC circuits, transformers, power distribution, etc.

My chief instructor made a point in reference to the US / Canadian training differences just a few days ago. In the US electricians often specialize and the training reflects this narrower skill set. In Canada we are expected to know-it-all-do-it-all.

@Chumly,
The best way to teach anything, Chumly, is to make theory as practicable as possible. While this may seem like a no-brainer, it is exceedingly difficult for many people to figure out good ways to show the real life relevance of anything that is being taught.

@JTT,
Good point!

Luckily, at least to some reasonable degree, I can relate the math/theory I teach to specific real-world conditions. Not all by any means however.

And it has to be in the context of the student's experiences, otherwise the impact is substantively lessoned (pun).

This is one area where I think, and I say I think, because I don't know enough about electrical/wiring to comment fully, that the laws you have to teach COULD be demonstrated in a real life fashion that would make them easier to grasp and see the significance of.

@JTT,
Which particulars do you feel have the least chance of a real-world translation?

I hated my circuits coursework...

I can make a pretty cool solenoid gun with a PVC pipe, a spool of speaker wire, and a computer power supply though...

That's probably outside of your curriculum though...

@Chumly,
If you use negative-reinforcement delivered through electrical current, I'm sure you could find practical application of just about any electrical law.

Good luck.

@Chumly,
Hey, I'd be happy to help out if anything beyond resistance in parallel vs. series circuits wasn't beyond me...

I might learn more about M.C. Esher as it turns out that (presumably) the grid he used to template his art has intuitive/mathematical underpinnings.

I teach vectors, phasors and geometric planes; these collate with resistance, inductance and capacitance calculations.

Maybe I could lace the drinking water with LSD and give them all M.C. Esher artwork to study.
