Statistics education research, Project-based learning, Teacher development, Statistical thinking


This paper describes the evolution of “recognition of need for data” and “strategical thinking”, two types of thinking identified by Wild and Pfannkuch in their Framework for Statistical Thinking in Empirical Enquiry, as well as its relevance for math teacher professional development. The research was carried out with ten in-service secondary-school math teachers during an educational experience (at Bogotá, Colombia), who, in the beginning, showed high performance in procedural knowledge of data analysis. The experience was founded on project based learning that participants proposed and conducted via a survey concerning implications of a Bill, relevant for their job context. These teachers made mistakes and showed difficulties during the two first stages of the investigative cycle, problem formulation, and research planning,  due possibly to their inexperience in designing an empirical inquiry. Teacher educator’s guidance, to turn mistakes into learning opportunities and teachers’ active participation, promoted the development of statistical thinking, especially linked to the types aforementioned.

Abstract: Spanish

Este artículo describe el desarrollo de “reconocimiento de la necesidad de los datos” y “pensamiento estratégico”, dos de modos de razonamiento identificados por Wild y Pfannkuch (1999) en su marco para pensamiento estadístico en investigación empírica, así como su importancia en la formación de profesores de matemáticas. La investigación se lleva a cabo con diez profesores de matemáticas en ejercicio, durante una experiencia de formación (Bogotá, Colombia), quienes al inicio del curso mostraron un buen nivel de conocimiento procedimental en análisis de datos. En el marco del Aprendizaje Basado en Proyectos, los profesores propusieron y desarrollaron una encuesta relacionada con las implicaciones de la implementación de un proyecto de ley, relevante para ellos. Los profesores cometieron errores y mostraron dificultades durante las dos primeras partes del ciclo investigativo, formulación del problema y planeación de la investigación, debido a su falta de experiencia en la formulación de un estudio empírico. La orientación del formador, para convertir las debilidades en oportunidades de aprendizaje, y la participación activa de los profesores favorecieron el desarrollo de razonamiento estadístico, especialmente asociado a los dos tipos de razonamientos ya mencionados.
