摘要：This paper analyzes the role that a group of college teachers of physics assigns to the comprehension of instructions and of concepts. Based on a text fragment, used to trigger answers, we discuss the "forms" that are attributed to the comprehension of this fragment. These results are compared with those obtained by the selection that this same group of teachers does about the factors that rule when favoring the teaching and learning of Newton’s laws
