To help with this, I have started looking at how I can use SOLO to structure the process of design development.
Earlier this year, I made this questions sheet to refer to when helping students analyse their research work. I thought that this could also be the starting point to make the steps through design development.
Here is my first thoughts on how this could be put together :-
Unistructural - they identify the main features of existing products that are similar to what they are thinking about designing.
Multistructural - they combine elements of what they have researched and list / label / describe the main design elements they have included.
Relational - analyse what they have drawn already in terms of shape and add design elements. These decisions are analysed and explained.
Extended abstract - further development drawing fulling successful elements together. Analysis explaining next steps.
Here is the support work I put together for this and I have tried it out on my Year 10 group.
