I even didn't know the squeak-dev image, but this last question seems a
good one. Most of the time Squeak has been oriented toward childs, and I
mean, really young childs, so what about "a system for children of all
ages"?. I'm trying to use Squeak with a pretty eclectic groups of
students in university (the only thing they share is that all them are
pregrade students) and I come to squeak after having previous
experience with Scheme and Python (that were previous sucessfull
experience with students with a more common background and interest in
"Computer Science", which I prefer to call "Informatics"[1]). It was a
pretty good thing to choose Squeak this time, I'm proud of that choice
and I will stick to it in the future. This construction was not an easy
one and is still being made. We need more content that can be used for
the students profile I talked before, here in LatinAmerica, and we're
trying to produce a selection of lectures and in the end some kind of
original material.

Now we can even make a little exploration of E-toys, but my feeling is
that the time is comming when we need to start learnings and asking
questions about Smalltalk.

I'm agree with this also. I think that both themes are not disjoint and
is a bridge for making "a system for children of all ages". Sorry if
this mail is taking too long, but I will try to talk more about bridges
and my previous experience teaching "Introduction to Informatics"
(anyway I read all of you a lot, so its time for revenge :-P )
In that course we try to make a first exploration of informatics from
the point of view of a "first in width" instead of the classical one (at
least here), the "first in depth" (you know, the one where the students
firs encounter with informatics is procedural structured programming, in
C/C++, then Object Oriented Programming, In Java/.Net, then Data Base,
etc... and in the end of their career studies they come with some kind
of revelation and they join the pieces and say "Ohhh this is
informatics"). In our first in width approach we try to know something
about story, social context, subfields in a panoramic way and the course
then goes to programming (because they need to being motivated and
prepared about the "now in depth" approach of the following courses). In
my previous semesters I tried to follow the path proposed by the people
of Teach Scheme Project, about:
1) Keep away from Machine Details (C/C++ is not enougth far from a
beginer point of view in my student and teacher experience) and
2) Focus on correctness instead of eficiency (focus on program desing).
and they key was the K.I.S.S. principle (Keep It Simple Sintactically).
Was really nice to see all the class having their first program working
and understood. And the teach scheme project has a emphasis on learned
oriented programming environments, so was nice to see programming seeing
as a "liberal art" instead of something teached for programers by
programers (in the same way that mathematics is not only for
mathematicians). To make a long story short, then I probed python
because it maintain the same K.I.S.S. principle and will be more like
the program languages they will find or have found in the rest of ther
studies. That was nice if all the people were students of informatics but...
This semester I have and eclectic group (the course was made an open
one), people from biology, informatics, engeenering, nutrition, some of
them are just starting their studies, some of them were finishing
them... and scheme and python were not the solution for that group. The
programming environment was "deprived"... was something like a "wordpad
with sintactical hightlighting"... their motivations where different, so
I need to appeal to a shared cultural background this time, and
computers where nice multimedia, connected, feature rich machine for
them. In that context Squek/Smalltalk was the answer. It provides a
bridge from computers in the world to computers in the classroom, and
different people were more motivated.
Now we need to start to make bridges from computers in the classrom to
programming as a part of a scientific discipline and even part of life,
and young children materials are not filling the gap for my students. We
need to make a bridge between our classroom and your community... that's
the reason why I'm here and I hope you help me.

Thanks for the advice. I will try to follow it, this week.

I feel that few bridges between communities are making education a
mission impossible... but I have made a log mail already...
