The difficulties of learning chemical concepts have been the subject of research for several years. The explanations that have emerged from them are classified in two groups: the first are those derived from the teaching process, and the second are those derived from nature and complexity, typical of the abstract nature of chemical concepts. Other approaches to the study of these difficulties include, on one hand, those arising from the relationship between the mental capacity of students and the demand for a task and, secondly, the lack of meaning and conceptual discrimination by students regarding signifiers associated to communication processes in the chemical context.

While it is true that research is as a way to solve problems, man has used it as a tool for a long time, their entry into the field of education, as a teaching strategy to enhance learning is relatively recent.Teaching and learning research is the development viewed from two aspects; one as the most used by researchers in science education in Spanish and Latin American contexts and another is the Anglo Saxon. This paper presents sorne ideas of inquiry as a context within research stands as one of the forms of active learning and describes two aspects mentioned about teaching and learning through research.
