Dear discussion group,
The missing link is knowing how the software works. My students learn
how to use a paper Stereonet, but also learn to write their own simple
Stereonet program. For the ones who succeed the modeling software is
not a black box anymore.
The problem is that nowadays students have to learn so many more
things than I had to in the seventies so time is short. It is so
tempting to cut corners, leave out the basics and learn to push buttons.

All of you,
I agree with Luiz. But the mining students have to know what buttom
use to produce good diagram. On ArGis, Gemcom, and blabla, they have
to choice between Schmidt and Wullf projection. Have a look ! Most of
the diagram are plotted in Wullf superior with structural structures!
Nobody see that...expect one day a manager!
So,some hours to explain Wullf and Schmidt diagram are quite important !

Dear all,
I am in agreement with Mike and Alex, we have exactly the same
problem in Brazil. I spent 6 years as a structural geology
demonstrator, and every semester I heard the classical question: why
should we learn how to make plots on stereographic projections if we
have a computer program to do that. Even my class mates did the same
when we were all undergraduate students. And, believe you or not, are
working on petroleum and mining industry here in Brazil. In fact, to
get job in many of the mining and petroleum companies (and we are not
talking about small companies here), the candidates have to know
Vulcan, ArcGis, bla bla bla. You don´t need to know even to make a
simple 3D sketch, or to plot a foliation on a Schimidt-Lambert net,
but if you know which buttons you have to push in such softwares, you
will be certainly hired with a very good salary. I am not saying that
computer stuff are rubbish, of course they aren´t. However, we must
remember who we are, which training we had and have, and show to those
people that we are not simple monkeys to push buttons on a keyboard.
Maybe we will hear that we came from the OLD SCHOOL (I´ve heard that
when I was doing field mapping with a master student which believes
that field relationships were not important if we have mass
spectometer...hahahahahahah), BUT WHO CARES? I was really bad on 3D
visualization when I began to study structural geology, sometimes I
still have terrible fights with the equal-area net, but I believe that
with patience and lot of effort, we can do good work on structure and
tectonics using pencil, field notebooks and paper sheets, and a net to
plot structures.
sorry for my english & all the best to all,
Luiz
