I probably shouldn't sell the students short until I see who actually
shows up.

That's a big part of what I am saying.

But the impetus for the class was a request from a couple of
people who have already attended two previous entry-level
classes taught
by the radio club in the next town over. I saw their material; it's
good; anyone who managed to attend their class and not pass is either unmotivated or unteachable.

I'm not convinced. Did you sit in on the classes and see what was
actually presented? Were the students able to attend all the classes
or only some? Good material, by itself, isn't going to guarantee
success.

I suggest that if you have low expectations, the class will
live down to them, and if you have high expectations, they
will live up to them.

You have an excellent point, and I will try to act on it.

Thanks

On the other
hand, I do have to be realistic. I have to adapt the material to the
level of the people in the class, to the best of my ability and striving
not to pitch it so low that part of the class gives up in disgust.

That's true of any class, isn't it? Particularly one where attendance
is 100% voluntary.

With all due respect, if someone cannot grasp the
concept of what
a frequency is, they should not be a licensed radio amateur,
IMHO.
Such a lack of basic radio knowledge means the
person just isn't
qualified yet, and endangers both the person
and those around them.

I think you've gone too far because I went too far in my example.

I stand by my statement. There must be certain minimum
qualifications to be a licensed ham. That doesn't mean a
high level, but it does mean all hams should know the
basics of how radio works. Otherwise the whole purpose
of the ARS is undermined.

The students in this class live in rural Minnesota. Electronics is
foreign to most of them. They can run a GPS-controlled tractor
and
cover their fields without double-spraying a single row, but don't
expect them to understand the concepts of how GPS works.
Or want to.

I'm not saying they should understand GPS to a high level. But
being from rural Minnesota doesn't mean they are incapable of
understanding basic radio if presented properly.

It's a real challenge to teach electronics to this demographic.
For one
thing, their motivation to learn the material is 100% related
to passing
the exam; they really couldn't care less that 1 amp will
flow through a
resistance of 1 ohm if 1 volt is applied.

They don't have to *like* it, they just have to know it.

Some of it I can make "real"
-- bring in a long extension cord, measure the resistance,
discuss what
that means when you put a welder at the end.

BINGO! That's exactly it - tie the seemingly-abstract theory
to a real-world practical example. Another would be a demo
of why short thick jumper cables are better than long thin ones.

I can tell you from personal experience that most of a teacher's
job in such situations is finding an explanation that can connect
what the student already knows to what is being taught.

Most of these folks will never be electronics gurus. They
don't need to
be. They need to understand enough concepts to
understand how to
operate the equipment that they buy.

Agreed. The license tests are the starting point, too, meaning
the person who passes them has met the *minimum* qualifications,
not that the person is an expert.

Do they need to understand the
relationship between wavelength and frequency to do that?

Yes! (IMHO)

No.

Sorry, that's one of the most basic things about radio there
is. All it really requires is an understanding that low frequency
= long waves and high frequency = short waves.

The whole point of license testing is to insure that
licensees know the basics.

I'm not sure that's actually true. Why do we care
that a Technician
licensee knows Ohm's law?

Because it's basic to the operation of radio.

Real world example: There's a lot of electronics out there
that requires a certain minimum voltage to work properly.
Typically 11.5 volts or so for "12 volt" equipment.
Some things, like camcorders, have automatic minimum
voltage shutdown. Most ham gear doesn't have such
protection.

At least some amateur transceivers will emit spurious signals
if you try to transmit with them using too-low supply voltage.
Synthesizer unlock and similar stuff.
Spurs that can cause interference to other radio services.
On top of that, most rigs draw a lot more current on transmit
than receive.

So if our new Technician doesn't understand Ohm's Law in
at least a very basic way, s/he could hook up their rig using
wire that has too much R, and then transmit all kinds of spurs
because the rig is getting too low a voltage on transmit. Yet it
will receive perfectly because there's enough voltage when
not transmitting. Indeed, the ham could even start a fire by
overheating the power supply wires.

It seems to me that the point of license testing is to erect a barrier
to entry. If that were not the case, the license pool would look a lot
different. It would consist of regulations and practical knowledge that
was actually used on a day-to-day basis. It would consist of
material
that, to use your phrase above, is essential to insuring that the
licensee is not a danger to the person and those around him.

Ohm's Law isn't just theory. An understanding of it is a practical
necessity for radio amateurs. Otherwise they're not qualified to
do what the license allows.

Then you need more time. It's that simple. The time can be
class time, or it can be time the students spend reading and
learning on their own. But it takes time to learn this stuff.

But I don't have more time.

Doesn't have to be *your* time.

It's going to be hard enough convincing
people to come to six sessions spread over three weeks.
If I asked for
more time, I would get no students.

How do you know?

The goal is to figure out how to
best use the time I have.
If I'm really successful, I will be able to lure people back to a
followup class. That's the only way I'll ever get access to more of
their time.

At a certain point, they have to be interested enough to invest
the necessary time and effort.

"If it were easy, everybody would do it."

And we're back to the concept of the exam as a barrier to entry.

No.

It's not about "barriers". It's about a ham knowing the basics.

If you have zero barrier, you have CB.

I would phrase it as "zero requirements". But yes, you have cb.
And look how that turned out. Should amateur radio become
nothing more than high power multiband cb? I say no.

If you have infinite barrier, you have
no one entering.

Of course, but the license requirements are far from infinite. They're
just the basics.
