Until now, there is no known specific and unified theory of the physics teaching. There are several currents of thought from which curricula, classroom activities, and extracurricular activities are designed, which consider in different ways the learning processes, the meaning, and purpose of education.

For this, we must consider the true meaning of the didactics of physics.
