From bert at freudenbergs.de Wed Feb 4 05:38:44 2009 From: bert at freudenbergs.de (Bert Freudenberg) Date: Wed Feb 4 06:44:49 2009 Subject: [Squeakland] Technical Report on OLPC Etoys Message-ID: A new Technical Report has been posted to the VPRI website, titled "Etoys for One Laptop Per Child" by Scott Wallace, Yoshiki Ohshima, and Yours Truly: http://www.vpri.org/html/writings.php Abstract We present an overview of the ?OLPC Etoys? system, describe the intensive two-year development effort that produced the system, and discuss lessons learned. OLPC Etoys is an end-user authoring system for children, which was chosen to be distributed with the OLPC XO laptops at an early stage of the OLPC project. Since we planned to derive OLPC Etoys by evolving an existing, mature system (?Squeakland?), it was expected to be a relatively straightforward undertaking. However, the OLPC XO platform?s special hardware characteristics, the evolution of the Sugar software stack, and the fundamentally international and multilingual nature of the project, all conspired to make the development effort challenging. Over the two-year course of the project, we successfully kept up with the challenges, and delivered usable Etoys systems for every OLPC release. We steadily improved the UI, added a few high-leverage features, and ?xed bugs, with a small and widely-distributed team and with help from the community. - Bert - From kbrown at mac.com Tue Feb 10 07:47:47 2009 From: kbrown at mac.com (Ken G.

This article describes a teacher, Ms. Hogan, who is an early adopter of a technological innovation: the authoring tool Squeak. We analyze email messages from Ms. Hogan applying Rogers' model for the diffusion of innovation. We find that this maverick teacher was quickly persuaded and decided to adopt the tool even before her knowledge of the tool was complete.

Which is not too much of a problem because the target group is different. And, maybe you can make it to Squeakfest California instead :) - Bert - From kim.rose at vpri.org Sat Feb 14 08:10:46 2009 From: kim.rose at vpri.org (Kim Rose) Date: Sat Feb 14 08:45:32 2009 Subject: [Squeakland] ANN: Squeakfest Brasil 2009 In-Reply-To: <86prhl7dr6.fsf@blue.stonehenge.com> References: <44C82D66-4454-48F5-BD06-695024ED404C@waveplace.com> <98F0A4B1-F868-41ED-8855-A07D932A58EC@vpri.org> <86prhl7dr6.fsf@blue.stonehenge.com> Message-ID: <041E4874-86A4-4B8A-ABFA-28C1C6BE4C67@vpri.org> This is too bad, Randy -- however, to be honest, Squeakfest Brasil is looking to assemble and host a greater number of teacher/Etoy users and curriculum developers and perhaps fewer "software developers" or those who may be planning to participate at OSCON. Bear in mind, we are also hoping to have a gathering in Los Angeles in August and will be posting additional information on that soon. best regards, Kim On Feb 13, 2009, at 10:07 PM, Randal L.
