.... One more question that seems to have come up. The student found today that saving the project in 3.9 (as a PR) doesn't seem to be reliable. At least that's the report I have. The symptom specifically, is some of the tiles that trigger on and off scripts don't seem to work after being saved into a PR file (and then being reloaded). I have no idea at the moment is this is the inexperience of someone new to Squeak or if its something else. From the students' experience, saving the project to a PR file is disabling some scripts whereas saving it in an image seems to be just fine.
I have almost no experience with etoys in 3.9, so can't speak to this issue -- sorry.
I've not heard of such issues arising in the versions of Squeak in which the etoys piece has been actively maintained, i.e. Squeakland and olpc/etoys. It would be interesting to hear if your students encounter the same problems using one of those systems -- if so, please send along a project illustrating the problem.
Finally, one last time, if you want a modern, up-to-date, documented, *supported* etoys experience, you'd be well advised to use the olpc/ etoys squeak image (or the forthcoming Squeakland release derived from that). These are *not* dumbed-down Squeaks; the "dev" versions are full-scale, industrial-strength Squeak systems, encompassing all of 3.8, plus Connectors, and incorporating countless enhancements and fixes. And a responsible and responsive development team. And, blessedly, an update stream.
There are two mailing lists devoted to uses of Squeak in education -- see:
