Children develop rich concepts of social categories throughout early and middle childhood. Whereas we know much about the development and consequences of many social categories individually, we know less about the development of representations at the intersection of multiple categories--for instance, how children think about race and gender…

The identification, diagnosis, and categorisation of students who qualified for special education have created long-standing controversy. This article explores Maximilian P. E. Groszmann's measurement practices, which were intended to facilitate instruction in the early twentieth-century United States. In 1900, Groszmann established a private…

In this article, we integrate two constructionist approaches--the theory of constructed emotion and rational constructivism--to introduce several novel hypotheses for understanding emotional development. We first discuss the hypothesis that emotion categories are abstract and conceptual, whose instances share a goal-based function in a particular…

Media for children reflects societal views about appropriate childhoods in that the content has been chosen based on adults' views of what is appropriate for children to engage with. In this article, the mathematics in puzzles and handicrafts in a selection of Danish children's magazines from 1925 to 1930 are analysed to understand the childhoods…

Integration of teaching protocol is an original creation of China's basic education. This model emphasizes the balance between the student as the subject and the teacher as the dominant. "Target-Guided Teaching" refers to the use of target guidance strategy to improve teaching, enabling students to effectively use information tools and…

What is it about afterschool that gives it so much potential to powerfully influence educational best practices around the world? This paper will explore what truly defines "afterschool" beyond the time- and location-based pedagogy of the term and will make the case for the use of "expanded learning" or "expanded…

ACECQA has published the second in its series of occasional papers, analysing one of the most challenging quality areas -- Children's Health and Safety. Quality Area 2 addresses one of the primary objectives of the National Quality Framework -- to ensure the health, safety and wellbeing of children attending education and care services. The paper…

In this article, the authors examine policies and interventions concerning special children in the United States and Europe from 1900 to 1960. They focus on concerns about, and interventions on, children defined as having "special needs". They explore interventions, both in the form of words and practices, and examine their effects on…

This article draws on data from an ethnographic study that begins with the experiences of educational professionals doing the "work" of educationally supporting students with long-term health conditions in a paediatric health-care setting in Victoria, Australia. The study was conducted over the same period of time but separately from the…

Is processing of conceptual information as robust as processing of perceptual information early in development? Existing empirical evidence is insufficient to answer this question. To examine this issue, 3- to 5-year-old children were presented with a flexible categorization task, in which target items (e.g., an open red umbrella) shared category…

The ability to infer the referential intentions of speakers is a crucial part of learning a language. Previous research has uncovered various contextual and social cues that children may use to do this. Here we provide the first evidence that children also use speech disfluencies to infer speaker intention. Disfluencies (e.g. filled pauses "uh"…

Two studies examined how children between ages 4 and 6 use body shape (i.e., the waist-to-hip-ratio [WHR]) for sex categorization. In Study 1 (N = 73), 5- and 6-year-olds, but not 4-year-olds, selected bodies with increasingly discrepant WHRs to be "most like a man" and "most like a woman." Similarly, sex category judgments made by 5- and…

How does understanding the decimal system change with age and experience? Second, third, sixth graders, and adults (Experiment 1: N = 96, mean ages = 7.9, 9.23, 12.06, and 19.96 years, respectively) made number line estimates across 3 scales (0-1,000, 0-10,000, and 0-100,000). Generation of linear estimates increased with age but decreased with…

Fourteen children with autism spectrum disorders (ASD) and fourteen age-matched typically-developing (TD) controls were tested on an adapted version of the Twenty Questions Task (Mosher and Hornsby in Studies in cognitive growth. Wiley, New York, pp 86-102, "1966") to examine effects of content, executive and verbal IQ factors on category use in…

Two experiments demonstrate that 14- to 18-month-old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some…
