Development of probabilistic understanding in fourth grade

We analyzed the development of 4th-grade students’ understanding of the transition from experimental relative frequencies of outcomes to theoretical probabilities with a focus on the foundational statistical concepts of variation and expectation. We report students’ initial and changing expectations of the outcomes of tossing one and two coins, how they related the relative frequency from their physical and computersimulated trials to the theoretical probability, and how they created and interpreted theoretical probability models. Findings include students’ progression from an initial apparent equiprobability bias in predicting outcomes of tossing two coins through to representing the outcomes of increasing the number of trials. After observing the decreasing variation from the theoretical probability as the sample size increased, students developed a deeper understanding of the relationship between relative frequency of outcomes and theoretical probability as well as their respective associations with variation and expectation. Students’ final models indicated increasing levels of probabilistic understanding.

Escenas de la vida de Santo Domingo de Guzmán

Resumen: “Escenas de la Vida de Santo Domingo de Guzmán” es el título otorgado a la bella obra atribuida al pintor Pere Nicolau, uno de los máximos representantes del Gótico Internacional en Valencia. Esta obra nos informa de la imagen simbólica de Santo Domingo, creada a partir de la literatura hagiográfica y las manifestaciones artísticas en la Edad Media, “cada una en su lenguaje, su riqueza y sus límites, y en ellos reside su belleza, su capacidad de sugerir y de permitirnos soñar o recrearnos”.
