[Sugar-devel] Adding support for new datastore to the XS...
Tomeu, Sugaristas, looking at the new DS as implemented in SoaS. To confirm, is this http://wiki.sugarlabs.org/go/Development_Team/Datastore_Rewrite what is implemented in 0.84? Maybe tagging the wikipage with a version moniker helps? Something at the top that says Sugar 0.88... cheers, m -- Forwarded message -- From: Martin Langhoff martin.langh...@gmail.com Date: Tue, May 5, 2009 at 4:52 PM Subject: Re: [Server-devel] backup : problem opening /library/users//datastore-x/store To: Hamilton Chua hamilton.c...@gmail.com, XS Devel server-de...@lists.laptop.org Hi Hamilton, Let's keep this on the list.

Great Sugar Digest and pointers, thanks. Walter Bender walter.ben...@gmail.com writes: Diego is of the believe that creativity is a skill that can be taught; For the sake of conceptual clarity, I would myself consider creativity as a meta-skill: the skill to activate other specific skills and make something out of them. Specific skills are those with a specific object/purpose: repair a bike, solve an equation. Creativity is only a generic skill, with no purpose pre-defined. Obvious hypotheses: 1. traditional teaching is good at teaching specific skills; 2. creativity can not be directly taught, only indirectly encouraged; 3. teaching creativity is meaningless unless teaching is creative itself, and focuses on creating the right environment for such a meta-disposition to engage into something interesting. As far as I understand it, Sugar is a digital version of such an environment. ... Food for thought for the next SugarCamp?

Re: [Sugar-devel] [IAEP] versus, not
My take on this over the years has excluded labels and categories for a variety of reasons. But I do think thresholds are important for most areas of learning. For example, at what level would an actually literate person consider a high school graduate to be fluent in literate actions and thinking? At what level would a mathematician consider a high school graduate fluent in mathematical actions and thinking? This is very different from asking questions about the level that a professional would need to attain. At levels below these two, we are talking about areas of study that are neither about literacy nor about mathematics, but something else. The something else could be useful (for example, reading street signs and goods in stores, or adding up simple sums). My main complaint about most schooling processes whether official or grassroots is that for a wide variety of reasons they settle for the something else rather than try to find ways to help the students learn the real deals. If the real deals are chosen, then the interesting question is what kinds of processes will work for what kinds of learners? If it is some non-trivial percentage of direct instruction, then this is what should be done (and depending on the learner, this percentage could range from 0% to a surprisingly high number). However, part of the real deal is being able to *do* the pursuits, not just know something about them, so all pedagogical approaches will have to find ways to get learners to learn how to do what practitioners do who above the two thresholds of fluency and pro. Tim Gallwey is one of the best teachers I've ever observed, and he had a number of extremely effective techniques to help his students learn the real deal very quickly (and almost none of these were direct instruction -- partly because, as he liked to say, The parts of the brain that you need to do the learning very often don't understand English!). But if he could see that the student had gotten on a track that couldn't be influenced by guided discovery, then he would instantly tell them to do it this way. In other words, he was not religious about his own very successful method, but instead did what his students individually needed and that worked the best for them (which happened to be learning by doing).

I would see direct instruction as a must for autistic children but don't see that it follows as a general model for all education (special needs are special) or that we should even think it is possible to have a correct general model. I don't think there is one and good teachers swap between multiple models all the time. no one on this list has argued overtly against the enlightenment or that local culture ought not to be taken into account, eg. Ties said think practical, the response was of the nature that our context demands we do a certain course of action however, I do think the roll back of enlightenment principles is not well understood (http://learningevolves.wikispaces.com/nonUniversals) and that a better understanding might persuade more people of the need to keep searching and struggling for different ways to go against some of the tide of local culture - there is a recent interesting comment thread on mark guzdial's blog which is worth reading from this point of view http://www.amazon.com/gp/blog/post/PLNK3F4TMBURELZZK ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

I think it's a great idea, very much in the spirit of the the Sugar UI design. I see a strong parallel to the proposed Text to Speech function, which would allow a user to highlight any text and then ask Sugar to pronounce it, or type text into a field provided by a frame device. In fact, I think that the Dictionary should also be a frame device, and the popup window should be a notification palette connected to that device. The question of key bindings is very interesting. In both cases, the functionality is useful to many users, but not all, so assigning a permanent binding seems excessive. However, clicking through the frame greatly increases the effort needed to use the feature. As a compromise, perhaps we can assign keyboard shortcuts of the form Frame key+letter to frame devices. This formula seems clarifying to the user, while also avoiding the hotly contested Ctrl- and Alt- shortcut spaces. --Ben signature.asc Description: OpenPGP digital signature ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
