===Logo===
Seymourt Papert developed a lot of work around teaching kids programming. What could an updated version of Logo be? ...maybe logo
scripting for kids (instead of php or java) :-)


====Cons====
==Introduction==
;Vaporware?: There are more than 150 different versions of Logo. Few of them are free, fewer are multi-lenguage, fewer have a nice GUI, none? On top of that Turtle Graphics is not really Logo. Kturtle is just Turtle Graphics and with the current version of KTurtle not even [http://mondragon.angeltowns.net/paradiso/Construcciones.html construct 24] can be drawn accurately.


Much of what passes for educational software in the commercial market is dreadful. Nearly always, it is either boring or uneducational. Often it is both boring and uneducational. We need tools, not just textbooks. There is a great deal of decent [[Linux education packages|educational software in Linux]] distributions which could be [[Sugarizing|Sugarized]].
====Opinions====
* Logo could be an excellent way to introduce programming and logic. I started with it!! I think this should be an starter way, but definitely and impreved new version (with more than one "turtle" at least). Today's children can understand easily and faster everything related to computers. And could be some kind of art too if are given the propers tools. (filling closed shapes, or maybe object oriented). Could be a very nice piece of soft!! --[[User:Gandolfi|Gandolfi]]


==Programming for Kids==
* LOGO is certainly a fun way to learn programming and/or to just play with a computer. Many modern implementations have multiple screen turtles. Perghaps at its simplest this can be found in ''MSWLogo'' (for Windows). - FREE. Newer flavors of LOGO are ''StarLogo'' and ''NetLogo''. They offer powerful ways of controlling large swarms of turtles and their environment - the great benefit being to encourage truly distributed ways of thinking and programming. --[[User:L Pfeffer|L Pfeffer]]
[[Programming for Kids|Programming]] is important for many reasons. It helps kids to learn math and logic. It helps them learn to clearly describe something in a structured and unambiguous way. It helps them to understand their computer, showing them that the XO is a non-magical device that functions according to logic. It provides the opportunity to share code with each other, including buggy or hostile code, making obvious the value of source code availability.


===Software to create Text Adventures===
===Squeak===
Squeak is an open source version of the Smalltalk programming language / environment. It can be used by children at the eToys level to program graphically by assembling objects and scripts; ( http://squeakland.org/ ) . Logo type graphics, learning and applications can be done in eToys as well, including the programming of multiple turtles for simulating complex behavior. Squeak can also be used by developers to write professional programs. The image runs identically on Linux, MS and Apple OS's; there is a separate virtual machine for each OS.


Also known as [http://en.wikipedia.org/wiki/Interactive_fiction Interactive Fiction]. However, MOOs are a bit more engaging but they need some sort of central server in which to create "the world". A central server might not be available where these laptops will. See [[Talk:Educational_Software#MUSEs_or_MOOs discussion]].
Connectors are one of the built in features of Squeak. Connectors allow you to easily create concept maps, flow charts, etc. with boxes and connecting links.


In that discussion it is argued that a MOO environment wouldn't work because it would require a central server to install "the world". Couldn't this obstacle be surmounted by allowing the creation of "personal worlds" or houses, that one child can share and another child can access when both computers are within WiFi reach? It seems that this kind of application is exactly what the OLPC should be focusing on, consider:
Active essays can be developed in Squeak. These are similar to books where each page can contain simulations running in real time. Active essays combine a written essay, live simulations, and the programs that make them work in order to provide a deep explanation of a dynamic system. The reader works directly with multiple ways of representing the concepts under discussion. By “playing with” the simulations and code, the reader gets some hands-on experience with the topic.

Constructivist Learning Using Simulation and Programming Environments
MIE2002H Readings in Industrial Engineering I
Calum Tsang
May 5th, 2004
The third, a multiplayer environment called [http://www-static.cc.gatech.edu/fac/Amy.Bruckman/thesis/index.html MOOSE Crossing], touches
on a previously minimized area of constructionism, that of social
relation. Ego syntonicity has already been covered as a required
characteristic, however, the social interaction and structure for
these activities has not.
Papert described the Latin samba school as a constructionist
activity with the added benefit that a social environment was also
present. MOOSE Crossing, a multiuser game similar to a Multi User
Dungeon (MUD) is both programming exercise, creative writing outlet
and social scene. Students are invited as an after school project
to play and build in this virtual space, programming automated
interactions and crafting textual descriptions of people and
objects in this microworld. "Knowledge is not passed from teachers
to students but is developed by everyone through their activities
and interactions with one another" (Resnick et al. 1996b: 48).
The environment is a social place, and there is a desire to share
creations in it. Many aspects of real-life relation are present
in this community context, and manifest themselves as part of
creating projects or experiences in the virtual world. In one case,
the authors noted the students built social capital by creating
objects others liked. Also unique to MOOSE Crossing is its verbal
aspect: While other projects highlighted so far have leaned towards
mathematics and science, this environment encourages writing.
Objects in the virtual world must be described, appealing to
students who have strong verbal skills. The authors also suggest
this as a way to link verbal skills to developing analytical
abilities.
One can draw parallels with other constructionist activities:
The students in MOOSE Crossing work on projects that are very
personal, often driven by personal interests and meanings. At the
same time, this is expanded into a social context that goes beyond
the individual.


==Software to Support Education==
====Cons====
This refers to software that does not teach anything directly but is available to facilitate learning. Examples include wireless chat and dictionaries.
;Bulky: Will it be able to run in the available hardware?


===3D Communication===
===A Concept Mapping Tool===
http://www.aprendelibre.net/wiki/index.php/Software_Libre_y_Mapas_Conceptuales
[http://www.sketchup.com Sketchup] is a very powerful 3D modeling program that is very intuitive and easy to use. After watching me for only an hour, my little 6 year old sister was making some pretty cool looking houses with rooms, stairs and such with absolutely no help. This ability to communicate in 3D is a very useful skill. The creators of the product have shown a deep commitment to helping advance education, (E.G. software is free for students and educators), and might be interested in this project if someone contacted them.


Or FreeMind basic MindMapping tool (built in Java) http://freemind.sourceforge.net
But is there a Linux version? --[[User:Walter|Walter]]


===Unit Calculator===
:It is closed software. Sketchup was bought by Google recently. It is unlikely (but not impossible) to have this software under a free license. -- [[User:Mathias Schindler|Mathias Schindler]] 02:30, 4 April 2006 (EDT)
A calculator that takes into account the units of the numbers. Some tool to be able to make calculations like [http://futureboy.homeip.net/frinkdocs/index.html#SampleCalculations these].


===Dictionary software===
:No Linux version, non-free, we will certainly not ship this. --Ivan Krstic
synonyms, antonyms, definitions, English/Spanish (or other language) translations, pronunciation


There are lots of dictionary programs available, defined file formats, and dictionaries. One of the formats is [http://sdict.com/en/format.php SDICT] which is used by various client programs including various types of mobile phone. Because they have already done the work to make a small compressed format we should leverage that and use their dictionary files. [http://swaj.net/sdict/index.html Alexey Semenoff] has a page discussing the work of the sdictionary project.
===Concept Mapping Tools===


A Python client for Symbian S60 can be downloaded from [http://www.fir.st/michael/pydict.html this site]. It shows how to read the sdict format (conv.py) and how the dictionary can be further compressed to use on a device like a mobile phone or OLPC (src/pydict.py).
Something like Inspiration/Kidspiration but with better networkability for collaborative editing. I like the concept of CMapTools, but its a a big java app.


In summary, Sdictionary is a dictionary that uses its own dictionary format. Unlike ptkdic or gtkdic, MySQL isn't needed; you can work with dictionary files directly. It uses Unicode, meaning that words and articles all are in UTF-8. There are two index levels, compression, and tools to convert from text files to .dct and vice versa.
View Your Mind (http://www.insilmaril.de/vym/) is an open source Linux mindmapping program which runs in a small memory space. It is included with the Puppy Linux distribution. Free Mind (http://freemind.sourceforge.net/wiki/index.php/Main_Page) is another open source mind mapping program; it may have a larger memory footprint, however.


Many dictionary databases are already available, some of them in target languages like Hindi, and Brazilian Portuguese. The fact that Python tools are available makes it easier for application and content developers to integrate this into their projects.
Mind Manager Smart is a discontinued mindmapping product for elementary school children from Mindjet (www.mindjet.com). It is very well done application and is a pleasure to use. It is useful for adults too. Perhaps Mindjet would consider donating this product to the OLPC effort. It could get them some free advertising for their commercial product. --DaveRaftery


===Arithmetic training software===
The Connectors package in Squeak (see above) allow easy creation of concept maps, flow charts, and directed graphs, with boxes and connecting links.


[http://www.4x4software.nl RekenTest] is a software package to train arithmetic skills, by offering arithmetic problems based on the child's performance, and throws in extra practice if needed. While this is training software, it might be good tool to include, as arithmetic skills are a basic part of a child's education.
===Touch Typing Software ===
Currently work is done to create a small size, low memory consumption version to run under WINE. Also an attempt is made to build a Linux binary with Kylix. Spanish and English are available, a Portuguese translation will be available soon.


[http://tux4kids.alioth.debian.org/tuxmath.php TuxMath], also known as "Tux, Of Math Command", turns flash cards into a game. It is a native Linux program. It has been translated into numerous languages including right-to-left ones.
A version of some Touch Typing software and typing games to teach these kids to touch type, the faster you can work with a keyboard whatever age you are then the faster you can get on with solving the worlds problems and letting the world know about your solutions... ' eg unjustified government spending on military budgets that will eventully only lead to one thing, more War to justify more spending etc..."


===Software to enable Participatory Simulations===
It should be noted that many keyboards are laid out far more logically than the Latin-alphabet QWERTY and its near relatives in France (AZERTY), Germany (QWERTZ), and elsewhere. Indic-alphabet keyboards have all the vowel signs on one hand and all the consonants on the other, and have the consonants grouped logically by sound type--for example t, th, d, dh, in one column. Also, the spelling rules are much simpler. So it is much easier to learn typing in languages that use these alphabets.


;Participatory Simulations : http://ccl.northwestern.edu/ps/ps.shtml
Also someone thing that is not clear but you don't need to be cranking the computer while you use it. Some one else could or if nobody else is available, you can crank for a while, and then type. Or you could use batteries charged from solar power arrays.


===Software to create System Dynamics models===


Like predator/prey models, scarce resources, snow ball effect (reinforcing feedback), dynamics of drug addiction, growth of human populations, exponential spreading of deseases, conflict escalation, dynamic equilibrium. These are the current software implementations all of them are non-free software http://sysdyn.clexchange.org/links_software.html
I found the follwoing list of Touch typing software that exists already, there are also a number of other existing companies that provide Typing Tutor Software (Mavis Beacon etc) and I would hope that for a project such as this the companies would be able to provide opensource alternatives.

==Teaching Software==
A description remains on the web.
[[Teaching Software]] refers to applications whose primary goal is to deliver educational content. In the western world this is often very poorly implemented in CBT (Computer Based Training) modules or tedious drill and practice software. These approaches are often shallow and demotivating. When provided with an engaging interface, or when external motivation is supplied, it can work.


===Ebook Reader===
http://www.howstuffworks.com/vios1.htm
This is teaching software that takes the rich and detailed content of textbooks and encyclopedias into the OLPC. ([[Book reader feature set]]).


===Story Teller===
There are also some notes on ViOS in the following document,
For children who are not advanced enough to make use of the Ebook reader, the computer should be able to read interactive stories out loud.


=== MIT Sketching ===
http://jlombardi.blogspot.com/2004_10_01_jlombardi_archive.html
[http://www.youtube.com/watch?v=NZNTgglPbUA Video demo]


===Interactive Assistants===
I wonder if I may please suggest that the ViOS look is worth considering as a way of indexing information sources for the users of the $100 laptop.
'''Drill software''' is based on the idea that some knowledge simply must be memorized.


On the other end of the spectrum is '''simulation software'''. Here the kids asks the questions and the computer do the computing. Afterwards the kids has to interpret the results. The idea is that computers are computing tools, and kids are researchers. A common problem is that the simulation model is deeply flawed. For example, a [[SimCity]] user learns that disconnected railroad fragments are a superior transportation network and that normal roads are unworkable.
It might perhaps be possible to have the display done by a relatively small program and the data in blocks which could be fetched from a server as needed.


A third model is called '''interactive assistants'''. Interactive assistants is assistants to the teacher, because they ask the kids questions in relation to a subject matter or a process the kids has to master: Like performing an interview: Which type of questions to ask, how to focus the questions etc.
William Overington


In this model the stand alone computers or more often web servers are programmed (preferably by using a user friendly backend, like a [http://en.wikipedia.org/wiki/Content_management_system CMS]) by teachers or text book authors to ask the questions that interactively (hence '''interacive''' assistants) leads the kids through the subject matter process in relation to the specific project they have (for example: To do an interview with a certain person). The model: Computers as structuring the kids' learning process (scaffolding), and the kids as the working and thinking part.

===The "ready-to-test" concept===
When teachers and kids around the world have access to computers and (hopefully) to the internet, the vision must be to develop a universal "open source" educational library of interactive assistants to assist kids to develop their competencies.

http://www.users.globalnet.co.uk/~ngo/ast00000.htm

===Virtual Manipulatives (for math learning)===


One argument for the design of virtual manipulatives has been saving money (physical manipulatives can be expensive, can be lost, can come in limited quantities). There is a library of virtual manipulatives available online http://nlvm.usu.edu/en/nav/vlibrary.html that provides a variety of activities and manipulatives for learning different math concepts.

:Please, let's not forget that the OLPC is for the delivery of content as well as applications. It is not a tech toy. I agree that physical objects that can be manipulated will make it easer to teach maths. But they don't need to be virtual. Include material to teach the children how to make manipulatives out of scrap wood or palm leaves. Include measuring tools so the kids can check their dimensions by holding the objects up to the screen. Integrate the construction of manipulatives into the learning process.

:No can do; we will not shipping or supporting Java on the laptops. --Ivan Krstic

===Java will not be available on the laptops - idea for possible alternatives, one for short term use and one for long term use===

I have noticed the comment about not shipping or supporting Java on the laptops in the section above and I seem to remember previously seeing somewhere that Java would not be used on the laptops because it was a proprietary product, even though, I seem to remember, there had been an offer of a free licence by Sun.

One key feature of Java is the portability of Java across platforms and such portability would be good for the future. So I am wondering whether the idea is the following document would be of interest.

* [[http://www.users.globalnet.co.uk/~ngo/catalyst.htm]]

If such a system were implemented in ISO/IEC 10646 (to which Unicode is locked) then the possibilities of a portable object code could be achieved without the proprietary aspects of Java.

William Overington

16 May 2006

Are the objections to Java based SOLELY on its non-open status? If Sun follows through on its recent announcement that it will open source Java, will this decision be re-visited?

jeffa
17 May 2006

It's safe to say that the largest impediment is the lack of an open jre from Sun. Sun has been making noises about open sourcing Java under an acceptable license for years. We would need action, not rhetoric. And we're already building out software in Python so the longer that they wait, the less chance it will be worth it to use Java. A couple of months ago we sent an olive branch to Sun and they rejected it so the ball is in their court.

Introduction

Much of what passes for educational software in the commercial market is dreadful. Nearly always, it is either boring or uneducational. Often it is both boring and uneducational. We need tools, not just textbooks. There is a great deal of decent educational software in Linux distributions which could be Sugarized.

Programming for Kids

Programming is important for many reasons. It helps kids to learn math and logic. It helps them learn to clearly describe something in a structured and unambiguous way. It helps them to understand their computer, showing them that the XO is a non-magical device that functions according to logic. It provides the opportunity to share code with each other, including buggy or hostile code, making obvious the value of source code availability.

Software to create Text Adventures

Also known as Interactive Fiction. However, MOOs are a bit more engaging but they need some sort of central server in which to create "the world". A central server might not be available where these laptops will. See Talk:Educational_Software#MUSEs_or_MOOs discussion.

In that discussion it is argued that a MOO environment wouldn't work because it would require a central server to install "the world". Couldn't this obstacle be surmounted by allowing the creation of "personal worlds" or houses, that one child can share and another child can access when both computers are within WiFi reach?

Teaching Software refers to applications whose primary goal is to deliver educational content. In the western world this is often very poorly implemented in CBT (Computer Based Training) modules or tedious drill and practice software. These approaches are often shallow and demotivating. When provided with an engaging interface, or when external motivation is supplied, it can work.

This is teaching software that takes the rich and detailed content of textbooks and encyclopedias into the OLPC. (Book reader feature set).

Story Teller

For children who are not advanced enough to make use of the Ebook reader, the computer should be able to read interactive stories out loud.

Interactive Assistants

Drill software is based on the idea that some knowledge simply must be memorized.

On the other end of the spectrum is simulation software. Here the kids asks the questions and the computer do the computing. Afterwards the kids has to interpret the results. The idea is that computers are computing tools, and kids are researchers. A common problem is that the simulation model is deeply flawed. For example, a SimCity user learns that disconnected railroad fragments are a superior transportation network and that normal roads are unworkable.

A third model is called interactive assistants. Interactive assistants is assistants to the teacher, because they ask the kids questions in relation to a subject matter or a process the kids has to master: Like performing an interview: Which type of questions to ask, how to focus the questions etc.

In this model the stand alone computers or more often web servers are programmed (preferably by using a user friendly backend, like a CMS) by teachers or text book authors to ask the questions that interactively (hence interacive assistants) leads the kids through the subject matter process in relation to the specific project they have (for example: To do an interview with a certain person). The model: Computers as structuring the kids' learning process (scaffolding), and the kids as the working and thinking part.

olpc and interactive assistants

When teachers and kids around the world have access to computers and (hopefully) to the internet, the vision must be to develop a universal "open source" educational library of interactive assistants to assist kids to develop their competencies.

Virtual Manipulatives (for math learning)

One argument for the design of virtual manipulatives has been saving money (physical manipulatives can be expensive, can be lost, can come in limited quantities). There is a library of virtual manipulatives available online http://nlvm.usu.edu/en/nav/vlibrary.html that provides a variety of activities and manipulatives for learning different math concepts.

(Shameless plug) I am also working on creating a new kind of virtual manipulative - one that attempts to build a bridge between artistic design efforts and mathematical learning. My desire to do this partially stems form the fact that I think some learners are more comfortable in either art or math, and that through this bridge they can step a little bit outside their comfort zones into the realm with which they are less comfortable (but still in a context they like). So, if you are very excited about art, you can try some math through your design activities, and if you like math but don't feel like you are very good at art, you can create some neat patterns that solve challenges posed from the mathematical perspective. I am interested in working with this laptop project.

I think that whatever (virtual) math manipulatives are available should be considered for this project. I would also like to see more of these virtual manipulatives developed for general use, but it seems like instances where money matters so much, this solution does not add any cost and would be useful.

Please, let's not forget that the OLPC is for the delivery of content as well as applications. It is not a tech toy. I agree that physical objects that can be manipulated will make it easer to teach maths. But they don't need to be virtual. Include material to teach the children how to make manipulatives out of scrap wood or palm leaves. Include measuring tools so the kids can check their dimensions by holding the objects up to the screen. Integrate the construction of manipulatives into the learning process.

Nelements is a generic 3d knowledge representation system that can be used to represent knowledge in a language of thought.

Educational Wikis

GiveThought.com (GT) is a wiki-based social entrepreneurship concept. GT will gather wiki lesson contributions to form coherent customizable learning curricula to be offered for free around the world to

  • Those who are unable to access formal education.
  • Those who wish to complement their formal educations
  • Those who wish to access information about subjective topics from an organized and coherent source.
