MAP &　case study

想请教MAP和casestudy 的差别。Ross 网站上有如下说法。但很难想象和理解。能给点现身说法吗？多谢啦！

In MAP, student teams are not presented with a well-defined problem, and then asked to choose from several possible solutions. Rather, it leaves the sense-making phase to students thus affording them the opportunity to develop both problem-solving and opportunity sensing skills. This problem definition, project scoping, and opportunity sensing are vital phases of the MAP experience. The critical skills developed through action learning are much broader in contrast to those developed through case studies.

They've talked about it in one of the Q&A threads.
