Yes! I am really interested in this, especially as it aligns with what I am wanting to do within my organization, Siyavula. We are based in South Africa and produce openly licensed Science and Maths resources for Gr 4-12.
I am the coordinator for Gr 4-9 Natural Sciences and Technology. You can view the Gr 4-6 content here: www.thunderboltkids.co.za. (Gr 7-9 website still coming). The "technology" curriculum that we had to follow, set by the Department of Education, is quite outdated though and focuses mostly on building physical models, such as making a bridge or a water purification system, etc. I do perhaps understand why they might have approached it as such, as there are many different contexts and learning environments in South Africa, most of which are rural and under resourced. In these contexts, they can only hope to complete very basic technology projects with the resources that they have.
However, at Siyavula, we are still interested in developing a more engaging, relevant curriculum to implement in place of the existing one. I would like develop a curriculum that educators can follow in their Technology lessons which also supplements and integrates into the Science curriculum. And Art and Drama lessons can also be used to then communicate the project in some creative way. I think projects that span different subjects at school could be very meaningful and provide a more real world experience. Just like Dan said - multi-stranded. And also like Lindsay said - project-based learning and the 4Cs are NB.
I would like to look at the Gr 4-9 age group, specifically at how to scaffold different technology tools/programmes/etc through the years, so that they build on each other. I would then want to take this general scaffold/curriculum and see how to integrate it so that it relates to our South African Natural Sciences curriculum.
Sorry, this is a bit of a long post!
Perhaps we could start a Google Doc and start to sketch out a curriculum? Just general points at first with links to the types of projects/tools/programmes you would suggest for each year, and building on each other?
