I taught computer literacy to fifteen-year-olds.

Teaching requires, in addition to subject matter competency, skill in 
classroom management and lesson planning and presentation.  I was hired 
having a CIS degree, but with no training in the other areas.  If you 
don't know what to watch for, the kids will go crazy.  Toss in the kids 
who weren't raised right (for whatever reason), and the situation 
becomes unmanageable.

Additionally, a typical school teacher takes an enormous amount of work 
home.  That takes its toll as well.

I quit after seven months.  My replacement worked for less than two 
years before moving on as well.

Regards,
John

I would have thought the biggest problem is that kids don't want to 
learn anything, don't give a damn what you're talking about, and will 
basically go to any lengths to avoid being taught.

_That_ is why I'm not a teacher.

Err, you do realise why it's called Manhattan geometry?

ID asserts that "life was designed by an intelligent, concious entity". 
That's all it says.

Now, if you mean "life was designed by an intelligent, concious entity 
AT THE START OF EARTH'S HISTORY", then you start to be able to make some 
predictions.

The first prediction is that the genome of every creature that has ever 
existed and will ever exist must have been somehow encoded into the very 
first lifeform(s) that the designer seeded the planet with.

By a trivial pigeon-hole argument this is laughably impossible.

It also pre-supposes that the designer knew exactly what habitats would 
exist in 4 billion years' time, which is also absurdly impossible.

(The best human scientists, equipped with mountains of measurement data, 
cannot even predict what the weather will do in 5 days' time, never mind 
what it will do over geological time. And you're suggesting that the 
designer /could/ predict all of this with /no measurement data at all/? 
I think not.)

To see how severe the problem is, consider the video I watched the other 
day. D. Attenborough visited an ancient lava flow in New Zealand. In one 
place, it had cut off an area of forest about 300 yards across. And in 
this one tiny island of green surrounded by barren rock, there lives an 
entire ecosystem of plants and animals. There are species of fruit flies 
there that live in this 300 square yard patch of ground, and live 
nowhere else on the face of the Earth.

You seriously expect me to believe that some designer 4 billion years 
ago could have predicted that the lava flow would move in this exact 
direction to leave this specific patch of green free for colonisation? 
Pull the other one, it's got bells on.

Well, that's a nice idea, but do we not teach children about World War 
II, because some lunatic claims that it didn't happen? Do we not tell 
them that the world is round, because a few lone idiots claim that it's 
flat?

Isn't part of the job of education to get the facts straight, so that 
kids know what to believe?

Now, that's not always possible of course. There are cases where we 
really aren't sure what the facts actually are. And IMHO that is a 
useful lesson too. If you're talking about the /origin/ of life on 
Earth, nobody has really conclusively figured that out yet. There's a 
bunch of plausible theories, but nobody is really anywhere near sure. 
But if you're talking about the /evolution/ of life... apart from a few 
lone crackpots, everybody unanimously agrees on the matter. So that's 
what we should teach.

Personally, I think they /should/ teach ID in schools. As an example of 
how to tell the difference between scientific fact and crude falsehood. 
(Apparently some people can't do this yet...)

Because it applies to the topology of the streets of Manhattan?

Like I said, I'm sure there's lots of other, similarly abstract things 
to which it also applies. It does /not/ however apply literally to the 
three-dimensional space that we all see around us.

But in all the cases I've found, it comes from them when they reach the 
limit of their knowledge - then they fall back on "God did it" because 
they can't explain any further.

  While there most probably are such people in existence, I think it's
pretty rare for somebody to have the opinion "I have no idea how complex
life came into existence, but I don't think it was by natural processes"
without also believing that some kind of god or other intelligence did it
as a conscious and deliberate act. I have never heard of a hardcore atheist
proclaiming that he doesn't believe that life could have formed by natural
processes (although I'm pretty sure there a few of those as well, but as
said, the are probably are very small minority).

  Attributing unexplained phenomena to a god (much less to the Christian
God of the Bible) is one of the oldest fallacies, and one which gets
narrowed down more and more as science progresses. Nobody in their right
mind, not even the most hardcore fundamentalist believers, would claim
nowadays that eg. the flu is caused by supernatural demons or that lighting
bolts are supernatural manifestations of a god. Why? Because nowadays we
know exactly what causes them, so there's no need for a supernatural
explanation. The "God did it" explanation recesses further and further to
the more basic elements of nature. Some hundreds of years ago almost
everything was caused by some supernatural phenomenon, but nowadays the
argument has had to recess so much that there's almost nothing left. The
only couple of things left are the tired old "where did the universe come
from" and "how did life from on Earth", and that's about it. About everything
else has already been explained by science so clearly that not even the
most fundamentalist of believers can resort to them anymore.

  This is basically the "god of the gaps" argument, and it's getting pretty
flimsy.

  So what you are implying with that sentence is that the concept of geometry
being used to measure and describe the real world is bogus?

  (And if what you are implying is that geometry is not an accurate
representation of the real world, making it a non-science, then by the
same logic Newtonian mechanics is not science. Heck, General Relativity is
most probably not science by the same argument.)

Except that they do, of course.

Heck, Bill O'Reilly (one of the FOX News guys) just recently tried to say 
that nobody understands how tides work, and that's proof that God exists.

Of course, he's no astrophysicist (unlike Neil DeGrasse Tyson, who 
answered that question for him on The Colbert Report last week <g>), but 
even I know how tides work.  And I understand how the sun goes up and 
down every day, too (which O'Reilly didn't seem to know, either).

  The theory of evolution != the theory of life's origins.

  The theory of evolution says nothing about how life first came into
existence on Earth. That would be abiogenesis.

  Basically the only thing that the theory of evolution postulates is that
the genes of large populations change over time (something even the most
hardcore young-earth creationists don't deny) and that some changes get
preserved while others disappear due to natural selection (again, something
the creationists don't deny). That's about it.

  The public doesn't get to decide the truth. That's just silly.

  So now teaching the theory of evolution is a government conspiracy. Right.

  Guess what happened to your credibility just now.

  Would you also allow holocaust-deniers, 9/11 conspiracy theorists and
anti-vaccinationists to teach at public schools, just for "balance"?
