SCHOOLS about design theory

i’d like to apply to some schools of design theory(industrial design),i have browsed many design school webpages,but i could’t find who can help,any information is appreciated.

I am not certain I have understood your question correctly. But if you are searching for a university with solid theoretical foundation you might want to look into the industrial design programmes offered by Delft University of Technology. You find more information on their webpage

If you are just searching for general advice on where to study design browsing the forum should give you a number starting points.

Good luck with your university hunting!
