¿Se pueden enseñar contenidos procedimentales en las clases de ciencias?

The paper we present raises a central question: Can scientific processes be taught in science classes? To be able to answer this initial question some previous issues must first be considered: Are the learning of processes new in the teaching of Science? If both researchers and teachers do not conceptualize these ideas in the same way, what then should we understand by the learning of processes? How are these instructional contents being investigated at present? Beginning with the identification of research areas in this field, we attempt to answer further questions: - Are there different levels of complexity in a single process? - How could we use these ideas in the planning of instructional activities? To analyse some of these considerations we have used the contents Tabulated Data and Control of Variables.
