And the more step sequences they cram the more dancing they have learned. Teachers often succumb to this market pressure, and besides, anyone can teach step sequences but few can teach dancing. At least not simultaneously to many students, all of whom have individual needs. The rest is just so many patterns. If you wanted to learn a language, the infrastructure of culture and grammar would be essential.
Any dictionary can supply any number of words.
Anyone who thinks they can learn a foreign language by translating word for word with a dictionary would be as foolish as someone who wants to learn to dance by concentrating on step sequences. Later I realized that those step sequences are purely didactic constructs designed to teach and practice smaller units. They are like molecules, and eventually you learn about atoms, and how to assemble your own molecules from these atoms. As I see it, dancing is not steps. Dancing is posture, balance, connection, leading, following, weight-changes, harmony, flow, and music.
