Actividades de Estimación de Medida: La interpretación de los docentes de Educación Primaria

Abstract: Resumen Este artículo presenta la caracterización del conocimiento matemático y didáctico sobre el concepto de estimación de medida que poseen los docentes de primaria chilenos, a partir de la forma en la que proponen utilizar actividades diseñadas y orientadas para trabajar este concepto. Para el análisis utilizamos una definición del concepto de estimación de medida construida a partir del trabajo previo de diversos autores. La metodología utilizada es cualitativa y de carácter descriptivo e interpretativo. … Show more

“…There is another interesting group of results on argumentation, in this case, from practicing teachers. In primary education, Pizarro et al (2018) conclude that weaknesses in estimation knowledge do not allow teachers to argue adequately. In another paper on integer numbers, Solar (2018) shows the importance of some strategies for the professor to encourage argumentation: giving opportunities for participation, managing error and asking specific types of questions, such as questions that favor explanation, avoiding rhetorical questions, asking counter questions and questions that keep the focus on the discussion.…”

“…In the first case, the estimation is made according to three processes defined by [53]: assigning a value, to perceptively execute the task, and linking the perception with the previous knowledge or with the mental image of auxiliar object. In terms of the MWS, the graph's elements are used as semiotic tools, the individual makes a proportional calculus taking as referent the magnitude of the height of the rectangle from de grid's graduation.…”
