Diseño de una unidad de enseñanza potencialmente significativa para el concepto de agujero negro

Abstract

The following research proposal aims to design and implement a Potentially Meaningful Teaching Unit (UEPS) for the learning of the astronomical object black hole in the classroom. Building upon the eight (8) sequential aspects proposed by Moreira (2005, 2011, 2014) for the construction of a UEPS that aims to lead to a re-signification of the concept of black hole, it is guided by the perspectives of meaningful learning proposed by Moreira (2005, 2011, 2014) and Camino (2011, 2021). Through an inventory of general concepts (IGC) about the concept of black hole, the methodological and didactic strategy used for teaching the astronomical concept aims to be validated. The UEPS was implemented with secondary school students. The success of the PMTU implementation process was analyzed using two instruments: 1) Formative evaluation of students' understanding of the concept of black hole, documented in the design and model of the UEPS as the final sequential steps in a qualitative manner. 2) At the end of the UEPS implementation, the conceptual gain achieved by the students regarding the concept was evaluated using the Bao and Redish (2011) statistical measure. This statistical evaluation reflects the students' mental state or model and their conceptual evolution, allowing for a quantitative validation and evaluation of the design of the PMTU for the concept of black holes.
