Which are the best simulation-based learning solutions, case studies
or other educational tool to achieve participant interaction in a a
middle management course of strategic management?

Hi doitnow, 

I was unable to find an independent site that reviewed the type of
simulation you are interested in. However, I did find an association
called ABSEL (Association for Business Simulation and Experiential
Learning) at Townson University. They maintain a list of simulations
that teach a variety of  business concepts.
http://www.towson.edu/absel/Packages/packages.html

Members of ABSEL come from the public, private and academic sector.
Their goal is to improve business education through experiential
learning. I think this site and its list of simulations would be
especially helpful because of their emphasis on experiential learning
(aka participant interaction).

If you have any questions or need clarification, don't hesitate to ask
prior to rating this answer.

Thanks!
