Re: [Phys-l] The attack on science is political, not philosophical



But, Skip, isn't the context of the flight simulator wuite different?
1. When I got in a simulator, I already new how to fly and could relate the simulator responses to those of a real aircraft.
2. When, as happened more than I care to remember, I screlwed up in the simulator, I not only survived to screw up another day, but I could remind myself that in real life I might not get the second chance.

I'm not convinced that the flight simulator analogy is applicable to the classroom.
Regards,
Jack

Thanks Brian. I know that simulators can be quite effective in learning to fly, particularly fly instruments. I wonder, though, if students have the same trust in concepts they struggle to piece together using simulators vs. the "real thing". Certainly they have their uses, (e.g. Interactive Physics scenarios) especially in tightening up relationships hinted at in lab investigations.

This is in the nature of an anecdotal response to Skip's question which
may possibly shed a little light.

Late last century, I needed to model the observable effects of
using some test equipment on a Navy trainer (simulation).
The equipment in question was a time domain reflectometer,
and a frequency domain reflectometer, which were (are?) used
to check aircraft signal cables operating at high frequencies.

It was not difficult to code an arbitrary signal generator with the noisy
spectral response that the data was intended to represent, with a
peak or dip at a particular frequency intended to define the ltransit time
and hence cable length to a discontinuity.

The time domain reflectometer display was also suitably presented
(I thought), with steps representing impedance changes at the
required variable distance and value and reflections and junctions
and terminal impedance....

A Navy user was not impressed however - the time domain was far
too clean for his taste. So then with the appropriate injection of
quasi random noise, the customer was satisfied.

This tale is meant to show that a simulation can portray more clearly,
more simply, than the real thing.
But what gains in clarity, loses in reality. There is a balance.

As a teacher who employs both simulated and real experiments,
I'd like to see a reference that the latter works better.
Do you recall where you read that, John?

The issue of dissection of animals is easily solved in HS. There are
virtual dissections available on the web, and according to some research I
have seen, they work very well. Indeed it is possible they might work
better than real dissections. .....
