El análisis de nebulosas planetarias: una secuencia didáctica aplicada con profesores de física en formación

Abstract

In this document, the development and implementation of a methodological proposal for teaching Stellar Spectroscopy with prospective physics teachers is described. A documental inquiry is initially shown, about the necessary theoretical references to design a didactical sequence. Such theoretical references are about: Astronomy teaching, Stellar Spectroscopy, planetary nebula, nebulae temperature, remote telescope, among others which allow to define the following structure in said sequence: Cover page, preface, objectives, teaching methodological proposal, theoretical framework, student workbook, suggested implementation and evaluation. The didactical sequence was implemented to eight students from the Bachelor in Physics program at the Francisco José de Caldas District University and eight students from the Bachelor in Physics program at the National Pedagogic University. Also, the realization stages for the proposal are described with detail, where the Universidad de la Punta’s remote telescope and the Planetary Nebula Spectra applet are used, and the results and analysis obtained from the implementation of the proposal are shown. On the other hand, an inquiry instrument is presented, validated by five Physics teachers which highlights the importance of teaching Stellar Spectroscopy. As way of closure, a general consideration is presented, from four cross-cutting aspects from the proposal development: i Construction of the didactical sequence, ii Implementation of the sequence, iii Definitive version of the sequence, iv Scope and limitations of the methodology within teaching.
