Estrategia didáctica basada en el ciclo investigativo PPDAC para la enseñanza y aprendizaje de las representaciones gráficas de datos estadísticos en el octavo año de EGB

Abstract

In contemporary society, citizens face a large number of statistical graphs that have to be analyzed and interpreted for the understanding of facts and phenomena of reality. In that sense, the Ecuadorian National Curriculum of 2016 proposes the study of the Statistics and Probability since the first year of EGB. The objective of this project is to propose a didactic strategy based on the PPDAC research cycle, for the teaching and learning of graphic representations of statistical data in the eighth year of EGB. The project arises as a response to the problem identified in relation to the processing and representation of data. This is characterized by the low participation of students in the acquisition of their learning, as well as the use of statistical problems with a low level of complexity, which makes them less interesting and less useful for learning. The research assumes a mixed approach, therefore, the data collected are both quantitative and qualitative. The type of study is longitudinal, which is why results are presented in three moments. The results allow us to conclude that the intervention proposal contributes to the teaching and learning of the graphic representations of statistical data, because it includes the elements that make up a didactic strategy, making the learning show 76.9% (30/39) of students who correctly prepare the statistical graphs and 79.5% (31/39) that properly analyze the statistical graphs
