This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of 'normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement digitalcommons.unl.edu

In this work the results of organizing the scientific game “Young scientists” are shown. This game was carried out in three secondary and high schools in Bogota with about two hundred students from 9th grade. Different teams of students competed with each other answering questions and doing special tasks in this game. This activity, outside normal classes, showed positive results in increasing level of students’ interests to study science subjects and provided space for raising motivation, stimulating learning and developing high levels of skill in students. Key words: scientific game, young scientists, motivation, extra-class activities.

<span>El propósito de este artículo es analizar las nuevas oportunidades que nos brinda Internet para la enseñanza de química. Escogemos los aspectos más interesantes del uso de Internet como fuente de información científica y educativa. La educación a distancia también es de importancia en este análisis. Los nuevos medios educativos en la escuela, el laboratorio, el aula y la clase virtual de química merecen consideración por parte de profesores e investigadores. Mostramos además algunas perspectivas que brinda Internet para la educación de los educadores. Esperamos que este artículo proporcione información útil a los lectores y los alimente para que continúe la discusión sobre cómo contribuye Internet al servicio de la educación de Química.</span>
