I'm a researcher, I'm italian, and in September I'm going to start a research putting two 3D printer in two school with 5 years old pupils.
We will try to verify the impact of Doodle3D and Tinkercad in the education method regarding creativity, espression and geometry.

If some teacher has some experience in this field I'll be glad to hear news about them.

Thanks
