| Abstract (English): |
The objective of this study was to promote among university students the use of significant language to define chemical concepts. An active and participative methodology which includes initial survey, class exposition of fundamental concepts, personal work, debate and clarification of concepts, was tested. Two subjects were explored: the definition of differences between elements and compounds, and the different behaviour between metallic and non metallic elements. Exposition of the experimental results and development of didactic units revealed that greater precision was established in the use of chemical languages as well as producing reasoned exposition on the behaviour of the substances. It is concluded that the methodology is valid since students became actively involved in the learning process and positively valued the experience. [ABSTRACT FROM AUTHOR] |

El objetivo de este trabajo es fomentar el uso del lenguaje significativo para definir conceptos químicos en estudiantes universitarios. Se ensaya una metodología activa y participativa, que consiste en sondeo inicial, exposición en clase de los aspectos fundamentales, trabajo personal, debate y aclaración de conceptos. Se exploran dos temas: establecer la diferencia entre elementos y compuestos y el distinto comportamiento de elementos metálicos y no metálicos. Se constata en la exposición de los resultados experimentales y en la elaboración de de unidades didácticas una mayor precisión en el uso del lenguaje químico y una razonada exposición del comportamiento de las sustancias. Se concluye que la metodología es válida, ya que los alumnos se implican activamente en el proceso de aprendizaje y valoran positivamente la experiencia. [ABSTRACT FROM AUTHOR] |
