It is well known that many different formulations of nonrelativistic quantum mechanics are used and applied at a graduate-level quantum mechanics course. The various formulations differ dramatically in mathematical and conceptual overview, even though they make identical predictions for all experimental results. Why should one care about different formulations of quantum mechanics if each provides identical predictions for experimental results? The main reason is related to the circumstance that some problems are difficult in one formulation and easy to manage in another. Our intent, in this presentation, is to critically scrutinize these distinct formulations looking at the simplest way, and at the same time the most effective one, to introduce quantum mechanics at high-school level. In particular, we comment on why the Copenhagen interpretation is still nowadays the widely used approach.
