OLPC Courseware Review

This article is a stub. You can help the OLPC project by expanding it.

Introduction

There is a body of Open Source courseware that already exists. Please evaluate these programs and write a detailed review on this page. If you know of a program that should be reviewed, add it to the list.

Note that some of these existing projects may need to be ported in order to be usable. For instance changing the GUI from KDE to GTK. Please note this in the reviews.

Courseware to be Reviewed

• Isard
• KSEG
• Dr. Geo, GTK+ interactive geometry

Detailed Reviews

Interactive Geometry

Isard

• "only works under VisualWorks". A non-commercial version of VW is available, but requires registration. So it seems a deal would be required. The VisualWorks product manager's email is on the webpage. Perhaps Isard might be ported to squeak.
• Manual.
• Direct manipulation + macros + smalltalk.
• Unclear if internationalized (but I haven't even looked at the source).

Dr. Geo

• "Due to a lack of resources and time, I have decided to not maintain any more Dr. Geo. However it does not mean Dr. Geo will not evolve anymore, it is up to its users to do so. Therefore, if you think you can take over its maintenance, please do so and inform the Dr. Geo users throught its mailing list. Hilaire Fernandes, 20/10/2006". Is on sourceforge.
• Requires GTK and Guile.
• Manuals in Dutch,English,French,Italian,Spanish (but English is "completely out of date"). English google translation of the Spanish manual.
• Direct manipulation + macros + scheme.
• Internationalized.

KSEG

• Requires Qt3.
• manual.
• Direct manipulation + macros. No programming language.
• Internationalized.

Kig - KDE Interactive Geometry

• handbook.
• Direct manipulation + macros + python.
• Unclear whether internationalized or not.
• KDE's attempt to replace KSEG, Dr.Geo, KGeo(dead), etc. But seems to currently be missing much.

GRACE

• Looks long dead. Java.

GeoNet

• Java
• Internationalized? ENglish-ification of the website doesn't seem to be working, so its hard to tell how much is available in other than german.
• Linux installers (with and without jre) failed on an up-to-date x86_64 redhat. No rpms.
• Looks interesting, and rich. But java.

C.a.R.

• Java

Gambol

• Java

GeoGebra

• Java
• docs
• Direct manipulation. Macros planned.
• Internationalized (at least the docs are).
• Award winning. Wiki. I tried a mandrake rpm on a x86_64 2ishGHz redhat (current). The UI was sluggish. And had minor problems (an unreadable menu). 310MB memory. Otherwise nice. Resource usage makes this a non-starter, yes?

Other topics

PyGeo

• 3D "Interactive" Geometry
• 3D (may be a performance issue?)
• Python programatic interface. No direct manipulation for construction. (Someone needs to write a GUI wrapper;).
• Interesting in its own right, but not a competator for an olpc "interactive geometry" package.

Synthesis

Interactive Geometry

http://en.wikipedia.org/wiki/Interactive_geometry_software

Kig seems a locus of future progress, and is python scriptable. But it is not as featureful as others. KSEG(Qt3) or Dr.Geo(may be dying) might be added for features. But I've not actually _used_ any of them yet! And the wikipedia page suggests there are other possibilities worth considering! 66.30.117.127 18:43, 9 January 2007 (EST)
