Background: Individuals with Down syndrome (DS) experience health disparities possibly associated with high levels of sedentary behaviour (SB). We systematically reviewed SB measurement, levels, patterns, correlates, consequences and interventions in people with DS across the lifespan. Method: We searched these databases: Embase; PubMed; Web of…

The ancient Greek astronomers devised ingenious methods for measuring the size and distances of the Earth, Moon and Sun. The concepts were beautifully simple and although in most cases could only yield approximate results, they have the advantage that they can be understood by anyone with a basic mathematical background. The emergence of…

A laboratory experiment characterized by a whole-class data-pooling approach to generate a data set that can be used to test a model of the influence of ionic strength on electrolyte solubility is described and discussed. The design of the experiment makes efficient use of the laboratory period and releases time for instructional and dialogic…

The Next Generation Science Standards list scientific argumentation as one of the essential skills for students in K-12 education. Unfortunately, many teachers enter the classrooms without sufficient experiences with or knowledge of, this skill. A discourse analysis of twenty-one preservice teachers was conducted to study how preservice teachers…

This paper describes analyses of the K-12 computational thinking (CT) integration activities collected at two NSF-funded workshops, "Developing an Interdisciplinary Framework for Integrating Computational Thinking in K-12 Science, Mathematics, Technology, and Engineering Education," held in August and November of 2017 at Education…

This article proposes a mock oral argument exercise that can be used periodically throughout the semester to enliven undergraduate business law classrooms and guide students to higher-ordered learning and deeper understanding: pairing students to argue the two sides of actual court cases that illustrate class topics, with the remainder of the…

The fact that children have acquired the habit of physical activity therefore becoming physically and mentally healthy individuals has an important role in the formation of a healthy society. Physical activities during childhood and adolescence ensure that sports performance is at the highest level and also contributes to overall health values…

The purpose of this review of literature was to explore intersections between movement and gesture, and to examine their effects on singing. Music educators have long championed the integration of movement into music instruction. The effects of movement have been studied and correlations found between an individual singer's intonation, internal…

This article considers the value and role of early years music and sound activities in museum spaces -- in relation to children themselves, as well as to their families and wider communities. The article reviews literature around early years music and sound activities; early childhood and the museum; and the use of music and sound in museum spaces…

This paper presents a case narrative of a university dean who is charged with instituting change within her faculty in order to resolve the faculty's financial issues. The case narrative explores academic conceptualizations of entrepreneurship and describes the dean's context in terms of: her executive leadership team, the financial issues she was…

This lecture reports on aspects of a larger research programme focused on studying mental mathematics in elementary and secondary mathematics classrooms. It specifically addresses an unplanned aspect that became salient through the work conducted in these classrooms. In this research programme, mental mathematics sessions are designed on a variety…

We report on and validate a system for ranking the cognitive demand of mathematical tasks. In our framework, task rankings are determined by the sequences of units and unit transformations students might use to solve each task. Using this framework, we ranked a set of 10 fractions tasks. We then interviewed 12 pre-service teachers to assess the…

For decades early childhood educators in high-quality programs have understood that the transition into reading and writing occurs naturally when young children are surrounded by opportunities to interact with print in ways that are meaningful to them. The original edition of "More Than Letters," first published in 2001, showed teachers…

To allow prospective teachers to see mathematics as a useful tool to make sense of the world we redesigned a university mathematics content course for prospective elementary school teachers in the context of exploring income distribution in the United States. This allowed the prospective teachers to learn mathematics in a meaningful context and…

Pedagogical Grammar has been notorious for a number of controversial issues, among them how necessary and effective it is in assisting foreign language learners at the moment of language production. If language is understood as a formal system that is activated when put to use and grammar as a meaning-negotiating resource, there are aspects of…
