The MBA classroom experience will often resemble actual management experience wherein students are encouraged to examine problems, explore alternatives and apply theories and concepts to derive solutions. This approach helps hone critical-thinking, logic and problem-solving skills, preparing students for the daily challenges in the business marketplace. This experience is typically delivered in the form of discrete learning modules that may comprise a number of classes, activities and assignments ranging from just a couple of weeks to a full semester of studies. In fact, elements of one module may span an entire MBA program of studies. They may be taught by individual instructors or by teams of instructors, and they may be presented as independent classes or as an integrated unit.
