XOCamp 2

The XOcamp 2 miniconference, which was scheduled for late November, has recently been postponed until early January. Specific dates will be announced shortly and will likely be immediately before or immediately after FUDCON in Boston (Jan 9-11). The purpose of the XOcamp is to help frame our long-term software development effort. In addition, we will work on prioritizing requirements, features and goals for the next major feature release called XO Software Release 9.1.0 and the Sugar 0.84 release. It will probably be similar to XOcamp 1 in nature.

Subject Matter

Please submit proposals for topics to cover. These may include, but are not limited to:

Top concerns and requirements of users and countries including reviews of available feedback
Learning priorities and tools needed to support them
Technologies, applications and software design proposals
Process and infrastructure proposals
Current and needed research

Agenda

on hold pending rescheduling

This is a very early proposed agenda : please feel free to edit and improve it!

Mon : Administrivia, introductions, and negotiation of a detailed talk schedule, followed by vision, goals, process, & review of current feedback

Tue : country feedback review + scheduled talks

Wed : brainstorming + more talks

Thu : more talks + scheduling/resourcing discussions

Fri : summarize actionable items, publish week in review, update the roadmaps

Sat+ : reflection for the next miniconf; thoughts for Jan's community conference

Proposals

User and Country Requirements Definition

Who is the user and what do they want?

A summary of user input from deployment leads, students and teachers. An aggregated look at the top items requested. An in depth look at the motivation of a few specific requests. Time permitting, can include a discussion of how to turn user feedback in to actionable requirements. Can include a detailed "use case" explaining the technical environment and social context of a target school.

Distributing OLPC

Summary:Making OLPC models of communities and development more decentralized, OLPC has to encourage communities of free software developers around the world, has to listen to teachers and students inquires and has to give them ways of making them happen.

The distribution has to be in all the layers, technological, content, and pedagogical.

Communication between this layers has to be improved, developer meetings like the XOcamp must be also done in major deployment sites. RafaelOrtiz

i18n and l10n: 9.1 and beyond: The areas I would like to cover include:

Input methods: Out current input system (XKB) is not enough for Chinese/Japanese/Korean, and even existing customers like Ethiopia have needs which are met with considerable difficulty with XKB. For 9.1, I propose that we switch to SCIM[1], which should take care of most (if not all) of our current requirements.
Multiple, non English fallback languages: Many of our users will probably be multilingual. A Aymara speaker would like to see the UI strings falling back to Spanish translations in absence of Aymara instead of the normal, default English. We have the existing infrastructure in our core i18n infrastructure, implementing this is simply a matter of making changes in Sugar (and maybe Rainbow).
Language packs: The current system of language packs is not very reliable (it overwrites the original translations in the system, installations cannot be easily undone, no versioning, etc). I want to switch to a RPM based language pack system for 9.1, which will be easier to deploy (especially if the customization key mechanism gets support for RPM). This will require support for multiple locale directories, and I'll talk about that as well (Ubuntu uses a similar approach - I plan to reuse their patches if possible).
User modifiable translations: There has been a number of ideas on this - initially (during my last visit to 1CC), we were thinking of a "Translate Activity" which would let children add/modify translations, and optionally let them share the translations over the mesh. SJ and Scott have recently suggested a wiki-like editable UI, which would, definitely be much cooler ;-). I want to brainstorm on this, and try to figure out the amount of time we need to do this, the advantages, risks, tradeoffs involved etc.

Whether and how we want the volunteer community to help us with 9.1

If OLPC-the-organizations says that we support the open-source mentality and that we encourage volunteers, we should articulate exactly what kind of volunteer support we want and need, the kind of relationship the organization would like to have with the community, and the kind of support (including support and resources that are conditional) we can provide them with. Mchua 16:54, 29 October 2008 (UTC)

I personally think that it is especially important to articulate the kind of volunteer projects we won't support and do not have resources for, so that community members know what they have to do completely independently of OLPC. Knowing the answer is a no is better, for planning and getting-things-done purposes, than remaining in a nebulous "maybe?" state. Mchua 16:54, 29 October 2008 (UTC)

What does an electronic textbook look like?

Since the 1960s there have been experiments in high-powered educational software, but not a lot of textbook development that integrates this software into the text, and very little classroom experience. This session will look at the available materials, the types of software and content available, and the implications for future curricula.

What do we know? What examples do we have and what do they show us?

What opportunities can we see? How do we make this happen? What questions should we ask next?

Examples:

Edison Talking Typewriter to teach reading and writing to pre-school children
Ken Iverson's textbooks, Arithmetic, Algebra, and Calculus
Smalltalk and the Dynabook concept
Matlab, Mathematica, and other powerful software
Notebook and workspace formats and capabilities
Teaching programming to children: Smalltalk, Logo, APL, others
