Subject: Glowscript files
It was told that Glowscript was mentioned on the Modeling list.
Glowscript is a really nice idea from Bruce Sherwood, Ruth Chabay, and
David Scherer. Glowscript runs in most browsers (Firefox better than IE)
and is a 3D world that can be populated with objects that move around
runs in all browsers on all platforms, plus WebGL, which adds 3D
functionality. At least that's what I understand.
I have played around with Glowscript with the goal of enabling students to
deal with interactive simulations at home. It turns out that this is not so
simple after all. Some students don't have a functioning computer, and some
are not nearly as adept at using a browser on a desktop as they are on
their phone. And again, older computers run slower. As always, faster is
better. At any rate, some students are able to play around with the
simulations and others are not. Time is on our side, though. Eventually it
will work out, I think.
The other goal is to get students interested in programming. Some useful
programs can be very short and simple.
All of the Glowscripts I have played around with are at
It is not a pretty site, but there are some things in there that may be of
use to someone. All of the programs can be copied and pasted into your own
(free) account. Then you can make them better and more useful to your own
Caveat emptor. I am not a skillful programmer. But you may be able to see
possibilities to go forward. My dream world be to have simulations that
deal with the models of interest to us, simulations that students could
play with at home. Time will tell.
