Ask HN: Case study approach to teach computer science fundamentals?

There was a thread in HN on how to teach coding / computer science subjects. I couldn't help but relate to my MBA days and juxtapose it with my Comp Sci undergrad days. In MBA classes, case studies are the norm.A real world situation is given, the students go through the case, find possible solutions, discuss with professors and the professor introduces the theory only at the end of the case. Students go through dozens of case studies in each of the subjects as part of the course and are judged on the merit of their arguments and some assignments. What does HN think of introducing such an approach to teach CS fundamentals (Algorithms , DS and advanced topics)? Does such a thing already exist?

Edit : Forgot to add that the case study approach certainly helps relate theory to practise and make a student hit the ground running.
