A experimentação problematizadora na visão de Delizoicov: Aplicabilidade em modelos atômicos

Abstract

This work aims to analyze the problem-experimentation in teaching Atomic models based on Delizoicov view by checking their methodological contributions to student learning of the 1st year of high school. Held the exhibition of some theoretical points, seek to provide contributions to the topic discussed, creating ways and means to the chosen path. Featuring the theme, we present the understanding that the student can use their previous knowledge about the nature of matter, and the experimental problem, improve their understanding of the world, going to have a more formal basis, ie closer to the concept scientific accepted. To teach atomic models present three educational moments of Delizoicov, where the first is the initial questioning, the second time, the organization of knowledge and the third and final time, the application of knowledge. We observed in this study that the application of teaching moments Delizoicov contributed to the pedagogical practice of professor of chemistry, encouraging the participation of students and allowing more efetividadena learning.
