Activity theory has an interesting approach to the difficult problems of learning and, in particular, tacit knowledge.

Quite a different approach to the same idea (read: not science), but certainly interesting.

It could be an interesting approach but, I mean what do you do?

We've had rather an interesting approach from an Italian publisher.

"It's a very interesting approach that has worked well," he said.

Not one I'd want to repeat, but certainly an interesting and thoughtful approach to its difficult subject.

This is a highly interesting approach, and one to which we wish to give our firm backing.
