Recent worldwide epidemiological surveys of autism conducted in 37 countries are reviewed; the median prevalence of autism is 0.97% in 26 high-income countries. Methodological advances and remaining challenges in designing and executing surveys are discussed, including the effects on prevalence of variable case definitions and nosography, of…

The English learner (EL) population has grown by 35% in the last 20 years. However, in addition to new students being identified as ELs, the EL subgroup is being inflated by students who are not being reclassified within a reasonable and developmentally appropriate timeframe. These students, often labeled long term ELs (LTELs), are a product of…

Digital sandbox games such as "Minecraft" can be used to assess and support creativity. Doing so, however, requires an understanding of what is deemed creative in this game context. One approach is to understand how Minecrafters describe creativity in their communities, and how much those descriptions overlap with the established…

Purpose: This paper presents a reclassification of markers for mixed reality environments that is also applicable to the use of markers in robot navigation systems and 3D modelling. In the case of Augmented Reality (AR) mixed reality environments, markers are used to integrate computer generated (virtual) objects into a predominantly real world,…

Since the early 2000s, the use of the term presentism has rapidly increased in both the historical discipline and public discussions of history. Most recently, presentism has been widely discussed and debated in articles about the pulling down and defacement of statues in countries around the world inspired by the 2020 Black Lives Matter protests.…

This work provides a characterization of the learning of graph theory through the lens of the van Hiele model. For this purpose, we perform a theoretical analysis structured through the processes of reasoning that students activate when solving graph theory problems: recognition, use and formulation of definitions, classification, and proof. We…

Infrastructures support and shape our social world, but they do so in often invisible ways. In few cases is that truer than with various documents that serve infrastructural functions. This article takes one type of those documents--technical standards--and uses analysis of one specific standard to develop theory related to the infrastructural…

Michael Young has written extensively about "powerful knowledge" as the type of knowledge that should be central in education: knowledge that is -- among many other things -- reliable and potentially testable, that helps us understand the natural and social world, and offers us a language to engage meaningfully in moral and political…

From the point of word formation, the phenomenon of lexical blending is a common productive process, entailing the notion of combination of lexemes in so many languages. In the vast majority of literature on blends, they preserve a linear formation of segments with a shortening of both lexemes. However, in sign languages where morphological…

This chapter provides a primer on the evolution of terminology used to classify the Latinx/a/o population in the United States, the origins of the term "Latinx," and an analysis of how community colleges currently use the term.

As higher education institutions begin to reemerge from the global pandemic, they are reimagining how multimodal learning environments (MMLE) can be used to help shape future delivery modes. This article explores definitions for multimodal learning environments in terms of pedagogy, implementation, and management. According to this study,…

Background: Individuals with autism spectrum disorder (ASD) form a heterogeneous group, posing a challenge for clinical definition. Additional problems regarding the diverse clinical presentation arise from changes in diagnostic criteria according to the latest Diagnostic and Statistical Manual of Mental Disorders (DSM-5), with exclusion of…

Traditional Mongolian Language evolved through the history taking in its purview the Buddha's teaching of the Dharma through the route of the Tibetan language. This research study examined the chronology of the evolution of the Mongolian language and literature, the influence of Tibetan on its grammar and on the written Mongolian. The focus of the…

This article aims to propose a practical model for intra-lingual translation or "paraphrase" in another term. Paraphrase is a restatement of a text, rewording something written or spoken, especially to achieve greater clarity. This approach could help a troubled translator who is having issues translating a complex text into a receptor…

This study seeks to uncover the theoretical bases for the production of the classical Arabic phonetic terms and their elements in the means of generating terms for both lexical semantics and conceptual semantics. The research problem is concerned with examining the roots of generating these phonetic terms and determining the categories of their…
