Abstract (es)
En este trabajo desarrollamos un material didáctico sobre el tópico de la difracción de la luz pues consideramos que este es un punto de partida para el estudio de diversos fenómenos ondulatorios. La propuesta didáctica consistió en la elaboración de un folleto para introducir al estudiante y captar su atención hacia el análisis de dicho fenómeno, posteriormente se realizó la experiencia de laboratorio orientando al estudiante a confrontar sus argumentos antes y después de observar el fenómeno. Los resultados obtenidos demostraron que el hecho de plantear la situación mentalmente y buscar explicación en la lógica común para luego confrontar con la experiencia real genera un impacto mental que contribuye a la construcción de conocimiento, no como la búsqueda de alguna verdad, sino como la búsqueda de explicaciones lógicas y científicas a lo observado en el mundo natural.
Abstract (en)
In this work we develop a didactic material on the topic of diffraction of light as we consider that this is a starting point for study different wave phenomena. The didactic proposal consisted in the elaboration of a brochure to introduce students and to capture his attention towards analysis of this phenomenon, after that, laboratory experience was developed, orienting the student to confront his argumentations before and after observing the phenomenon. Results obtained showed that the fact of mentally posing the situation and seeking explanation in the common logic and then confronting with real experience generates a mental impact that contributes to knowledge construction, not as the search for some truth, but as the search from logical and scientific explanations to what is observed in the natural world.
