At university introductory physics courses, often problems are solved as a direct application of theory, as if they were exercises. In this paper we present evidence that students tend to solve problems in a superficial manner, without applying fundamental problem-solving strategies such as qualitative analysis or hypothesis making which prevents them from arriving at a correct solution. Using as a point of reference the solving of a problem that is usually regarded as an exercise, we propose some approaches that could serve as guidelines for problem-solving in Physics teaching, and stimulate reflection among students to find solutions, as well as use scientific procedures.
