Conocimiento del Intervalo de Confianza por Futuros Profesores de Bachillerato

ResumenEl objetivo de este trabajo fue evaluar el conocimiento común y especializado del contenido de los futuros profesores españoles de bachillerato sobre el intervalo de confianza. Para lograr tal fin se propuso a un grupo de 73 futuros profesores un problema abierto sobre intervalo de confianza, similar a los propuestos en cursos anteriores a los estudiantes de Bachillerato en las pruebas de acceso a la universidad. Además, se les preguntó cómo explicarían a un estudiante el significado del intervalo de confianza y sus propiedades. Utilizando una metodología cualitativa de análisis de contenido, se estudia el planteamiento, cálculo, interpretación y definición del intervalo y las propiedades que recuerdan. Aunque la mayor parte de los participantes en el estudio plantea y calcula correctamente el intervalo, sólo el 28,8% de los futuros profesores lo interpreta correctamente. Se encuentran interpretaciones deterministas o propias a la metodología bayesiana, similares a las descritas en investigaciones con estudiantes. Otros o no proporcionan una interpretación. Pocos participantes fueron capaces de definir correctamente el intervalo de confianza cuando se les pide explicar a un estudiante su significado y recuerdan pocas propiedades del mismo. Se concluye la necesidad de reforzar el conocimiento del contenido sobre intervalo de confianza en estos futuros profesores. Palabras-clave: Intervalo de Confianza. Conocimiento del Contenido.

To achieve this aim, we proposed to 73 prospective teachers an open problem similar to those proposed to high school students in the previous years at the entrance to university tests. Besides, participants were asked to describe how they would explain the concept and its properties to a student. Using the qualitative methodology of content analysis we study the setting, computation, interpretation and definition of confidence interval and its properties. Although most participants correctly set and computed the confidence interval, only 28.8% of them made a correct interpretation of the same. Deterministic and Bayesian interpretations, similar to those described in previous research with students arose or there was no interpretation. Few participants defined correctly the interval when asked how they would explain the topic to a student; additionally, only a few properties of the interval were remembered. We conclude the need to reinforce the content knowledge of confidence intervals in prospective teachers. Keywords: Confidence Interval. Content Knowledge. Prospective Teachers. High School.
