          Abstract

          La selección de los contenidos conceptuales en la química constituye un aspecto clave cuando se quieren enseñar. Este trabajo analiza cómo y qué del tópico "la materia" se presenta en los programas de estudio de primaria y secundaria chilena de las disciplinas de las Ciencias Naturales y Química, mediante el uso de conceptos y mapas de frecuencia. De esta forma, se determinaron la amplitud y diversidad conceptual según los niveles de representación utilizados en química. Los principales resultados indican que la selección de contenidos es muy variada, pero se caracteriza por ser discontinua y no estar bien estructurada. La mayoría de los conceptos son cualitativos y macroscópicos, contrario a los conceptos microscópicos y simbólicos que son presentados tardía y abruptamente en los programas, concentrados al final de primaria y al inicio de la educación secundaria. Estos resultados tienen un impacto directo en el diseño del curriculum que orienta los programas de química y cómo se enseña, en la formación inicial y continua de los profesores de ciencias y en la mejora de la calidad de los resultados del aprendizaje.

          Translated abstract

          The selection of the conceptual contents in chemistry constitutes a key aspect when approaching its teaching. This work analyses what of and how the topic "matter" is presented in the Chilean primary and secondary curriculum of the disciplines of Natural Sciences and Chemistry, by means of using concepts and frequency maps. Consequently, range and conceptual diversity were determined in accordance with the levels of representation used in chemistry. The main findings indicate that the selection of contents is varied, however characterized for being discontinuous and not well structured. The majority of the concepts are qualitative and macroscopic, conversely microscopic and symbolic concepts are introduced late and abruptly in the programs, being concentrated at the end of primary and at the onset of secondary education. These findings have a direct impact on the design of the curriculum that guides the chemistry programs, on how these are taught, on the initial and continuous training of science teachers, and on the improvement of the quality of the learning outcomes.
