Ricardo Moran was awarded a 2010 Google Summer of Code (GSoC) scholarship to create new tools for Etoys. The European Smalltalk Users Group (ESUG) was selected as a mentoring organization for the 2010 GSoC. The idea for the project Ricardo chose was submitted to ESUG by Randall Caton, a member of the Squeakland Education Team. Ricardo's project was selected as one of the top 5 ESUG entries. Randall Caton and Markus Gälli mentored Ricardo. http://www.pcs.cnu.edu/~rcaton/ESUG/ESUG.html

There is a DVD that can be seen on-line that looks at the educational role of Squeak http://www.squeakland.org/resources/audioVisual/. (It's called 'Squeakers' but could as well be called 'Etoyers'!)

The Etoys version of Squeak can be run either within a browser or standalone. The user interface is modified slightly to make it easier for the novice user. For example there are only 2 flaps: Navigator and Supplies; also selecting the desktop does not bring up a World menu - you have to press the escape key for the World menu. Programing is done using scripts which can be called up for any object from the object's Viewer halo. Tiles representing commands are dragged into a script on the desktop. There are a limited number of control structures available.

Stef Ducasse's "Squeak, Learn Programming with Robot" has an excellent 25 page chapter on the basics of using Etoys. His book is available at reduced cost from http://www.bookpool.com/
