Evaluating specialized knowledge for teaching statistics and probability: construction and validation of an MTSK-Stochastic Questionnaire ; Evaluando el conocimiento especializado para enseñar estadística y probabilidad: Elaboración y validación del Cuestionario MTSK-estocástico ; Avaliando o conhecimento especializado para ensinar estatística e probabilidade: Desenvolvimento e validação do Questionário Estocástico MTSK

International audience ; [Objective] This research presents the process of construction and validation of an MTSK-Stochastic Questionnaire. [Methodology] Through a process consisting of three phases – 1) bibliographic review; 2) construction of the initial version; 3) validation through expert judgment and subsequent implementation of the pilot (trial) – an open questionnaire was constructed to assist in gathering data for analysis and evaluation of aspects of specialized knowledge of in-service Primary Education teachers for teaching statistics and probability, based on the Mathematics Teacher’s Specialized Knowledge (MTSK) model and the Mathematics Teaching Itinerary Approach (MTIA). [Results] The evaluations and opinions of the experts were generally positive, although some elements of the initial questionnaire were eliminated and others were reformulated to improve clarity and ease of understanding. [Conclusions] The final version of the questionnaire, which consists of 5 items for the analysis of statistics and 5 items for the evaluation of probability, makes it possible to provide accurate evaluations of mastery of mathematical knowledge: knowledge of topics, mathematical structure, and mathematical practice; and, in the didactic domain, accurate evaluations of knowledge of learning standards and characteristics, as well as knowledge about mathematics teaching. ; [Objetivo] En esta investigación se presenta el proceso de construcción y validación del Cuestionario MTSK-estocástico. [Metodología] A través de un proceso que consta de tres fases: 1) revisión bibliográfica; 2) construcción de la versión final; 3) validación a través del juicio de expertos y la posterior aplicación piloto, se construye un cuestionario abierto para analizar y evaluar aspectos del conocimiento especializado del profesorado de Educación Primaria en activo para enseñar estadística y probabilidad, con base en el Modelo del conocimiento especializado del profesorado de Matemáticas (MTSK) y el Enfoque de los itinerarios de enseñanza de ...
