In recent studies, some researchers were eager for the answer of how to group a perfectly dream team. There are various grouping methods, e.g. random assignment, homogeneous grouping with personality or achievement and heterogeneous grouping with personality or achievement, were proposed. Some instructors could put some students in a team better via their experiences than some algorithms. And some algorithms would match students perfectly but in chance teams assigned by instructor also good enough. This phenomenon would stay continuance until a baseline algorithm is to be proposed as a baseline of comparison. Based on the above discussions, author has proposed a team-forming algorithm for heterogeneous grouping that could be used by other researchers to compare with.
