In this paper, we make a qualitative analysis of didactic experiments performed with five 6 to 10-year-old children and five primary school teachers, starting from a structured game with probabilistic elements. The fundamental idea is to stimulate probabilistic thinking not only by playing a card game with decision making in uncertain situations,…

'The National Curriculum for England, History Programmes of Study: Key Stages 1 and 2'. https://www.gov.uk/government/uploads/system/uploads/attachment_-_History.pdf, 1) states that the purpose of studying history is to inspire pupils' curiosity, to 'ask…

What are the nature, forms, and roles of metaphors in mathematics instruction? We present and closely analyze three examples of idiosyncratic metaphors produced during one-to-one tutorial clinical interviews with 11-year-old participants as they attempted to use unfamiliar artifacts and procedures to reason about realistic probability problems.…

This study takes an in-depth look at parental acceptability (i.e., the ability to meet parent needs) of an intervention that has shown strong empirical support for treating and preventing childhood conduct disorder. The authors obtained acceptability data from 30 parents of children ages 5 to 12 years presenting externalizing behavior problems…

Six-year-olds, 10-year-olds, and 18-year-olds were studied in a probability learning experiment using a procedure analagous to that used in animal experiments. It was predicted that children, like rats, would choose higher probability alternatives more often with a noncorrection than a correction reinforcement procedure. (Author/DB)

Mixed Rasch models add latent classes to conventional Rasch models, assuming that the Rasch model applies within each class and that relative difficulties of items are different in two or more latent classes. This article considers a family of stochastically ordered mixed Rasch models, with ordinal latent classes characterized by increasing total…
