I've worked for Plan Ceibal in Uruguay since it began, in some official and some unofficial activities.
I think I have a comprehensive field look on how Sugar is used in schools and how developers communities can contribute. Part of my experience is documented in the blog: proyecto-ceibal.blogspot.com; some of its articles have been translated by volunteers in olpc-ceibal.blogspot.com.
I'm currently working on two research projects related to Plan Ceibal and the 1:1 educational model:
- Proyecto Flor de Ceibo with Universidad de la República.
- ILATIS (Social Impact of 1:1 projects in Latin America and the Caribbean) with Fundación DESEM, within an international research team supported by IDRC-CRDI.
I recently produced the book "Ceibal en la sociedad del siglo XXI", which can be downloaded here.
Now we are organizing a second Ceibal Jam!, engaging local communities to develop software for Plan Ceibal.
