While some people prefer to process information upon the outer world (extroverted), others prefer to process it reflectively (introverted). This difference leads to distinct experiences and therefore to distinct learnings, despite the students being in the same learning environment. The research problem was the learning asymmetry in Production Planning and Control (PPC) by students with different Active-Reflective learning styles in a business game-based learning environment. The research question was: does the use of a business game generate a more effective learning process for students with an Active learning style? The main objective was to test the meshing hypothesis of the Active-Reflective learning style with the learning environment. The learning outcomes were assessed by means of an exam. Using Bloom's taxonomy (ANDERSON; KRATHWOHL, 2001) the exam assessed learning outcomes of the cognitive processes (remembering, understanding, applying, and analyzing) and of the types of knowledge (factual, conceptual and procedural). Active-Reflective learning style of each student was assessed using the Felder and Silverman (1988) inventory of learning style (ILS). Two quasi-experimental pre-test and post-test with separate samples were conducted; the first one, with 375 students, to evaluate the differences in the learning of students with different learning styles (Active-Reflective). The second one, with 100 students, aimed to study the effect of the increase of reflective activities on asymmetry of students learning due to their learning styles (Active-Reflective). The first quasi-experiment showed lower learning by Active students. To explain the results, the Kolb, D. (1984, p. 42) experiential learning theory was used. The experiential learning relies on the four stages of a cycle: concrete experience, reflective observation, abstract conceptualization and active experimentation. It was assumed that, the lower learning of the students with Active learning style, was caused by the lack of reflective activities during the business game. The Reflective students, who prefer the transformation of knowledge by reflective observation (introspection), were encouraged, by the game, to experiment actively the knowledge. They would have been able to close the learning cycle more effectively than the Active students: by reflecting, due to their personal preferences, and, by acting, due to the circumstances imposed by the business game. To confirm this assumption the second quasi-experiment was developed increasing the reflective activities of the experience. The results, then, led to the acceptance of the learning equality of students regardless of their Active-Reflective learning style. Based on the references and data observed in this study, it is suggested that the learning agents consider, in their teaching and learning plans, the cyclical nature of experiential learning, as defined by Kolb, D. (1984). In accordance with the studies of Felder and Spurlin (2005), of Belhot and Seno (2009) and of Felder (2010), it is suggested providing learning opportunities in a balanced way to students with any learning style. To the educators that already use games, it is important to encourage students, especially the Active ones, to review the results of the game and make reflective observations.
