A lot has changed since the release of version 0.1 last September. We now have 10+ learning activities including the subjects mathematics, English, and geography. You can download the Karma-2.xo bundle if you have a Sugar environment handy or you can try them right away using your web browser if you have Firefox 3.5 or Google Chrome. Unfortunately, the examples do not currently work on Safari.
One new Karma lesson that I am particularly proud of is the Karma version of "Conozco a Uruguay," or "I know Uruguay." Gabriel Eirea created the excellent original using pygame. If you aren't already familiar with "Conozco", it is a simple but extremely enjoyable lesson on Uruguay's geography. I was able to code up an incomplete but usable version of Conozco in just a couple of days. I have also created four-part tutorial series on how you can create your own "I know my Country" using Karma.
We are making a lot of progress at the moment and expect to have 60 fully working and classroom-tested Karma lessons by April. Why am I so optimistic? OLE Nepal has committed substantial resources to converting all of its lessons currently written in Squeak to Karma for reasons of performance and storage space.
There is also online presentation that you may find informative.
Thanks to OLE Nepal and Sugar Labs for their continued support of Karma.
