Analyzing and selecting tasks for mathematics teaching: a heuristic

In planning units and lessons every day, teachers face the problem of designing a sequence of activities to promote learning. In particular, they are expected to foster the development of learning goals in their students. Based on the idea of learning path of a task, we describe a heuristic procedure to enable teachers to characterize a learning goal in terms of its cognitive requirements and to analyze and select tasks based on this characterization. We then present an example of how a group of future teachers used this heuristic in a preservice teachers training course and discuss its contributions and constraints.

Un imperativo moral: la enseñanza de la estadística no puede dejarse al azar

La conferencia aborda la enseñanza de la estadística, destacando tres modelos específicos del área: la guía GAISE, el ciclo investigativo PPDAC, y el ambiente para el aprendizaje del razonamiento estadístico SRLE. Además, se centra en el desarrollo del pensamiento estadístico según la jerarquía cognitiva de alfabetización estadística, razonamiento y pensamiento estadístico.
