All authorities on the teaching of physics are agreed that the beginning work of a class in high school physics should be distinctly concrete in nature. It should consist of such subject matter as will readily connect up with the acquired concepts of the student. It is best not to begin with the unfamiliar, abstruse concepts of force, motion and acceleration usually placed first in the high school text.
