In this article, James presents the Extended Hundreds Chart, a task he used with Year 6 students to explore their thinking about and representations of negative numbers.

This article explores the possibility that John Dewey's silence about which democratic means are needed to achieve democratic ends, while confusing, makes greater sense if we appreciate the notion of political technology from an anthropological perspective. Michael Eldridge relates the exchange between John Herman Randall, Jr. and Dewey in which…

The motion of a bead along a path restricted to straight lines (restricted brachistochrone), sliding without friction from rest and accelerated by gravity, is considered. For two shapes of path, the geometry of the route optimized to provide the least travel time from one point to another is obtained. The bead's travel times, path lengths, and…

This commentary expands the notion that models and modelling can be used as a basis to foster an integrated and authentic STEM education and STEM literacy. The aim is to synthesize key publications that document relationships between authenticity, models and modelling, and STEM education. The implications of the synthesis are as follows:…

We present a framework to help those working in Extension connect program designs with appropriate evaluation designs to improve evaluation. The framework links four distinct Extension program domains--service, facilitation, content transformation, and transformative education--with three types of evaluation design--preexperimental,…

Paradigmatic pluralism in educational technology is a largely unaddressed reality, and we have heretofore not provided guidance to professionals on how to navigate it. Pushing back against mainstream views of scientific progress (e.g., linear, progressive), we must recognize the processes by which paradigms are born, adopted, and rejected and that…

Objective: This study describes the use of the Nutrition Education DESIGN Procedure for developing the In Defence of Food Curriculum, a health education curriculum serving as the companion guide to the In Defence of Food documentary film based on the book with the same title. Design: The DESIGN Procedure is a systematic stepwise framework that…

An easy operating tool has been developed for the quick measurement of thermoelectric power. The setup is made using a tweezer which consists of two circular copper plate electrodes. These copper electrodes are fixed to two arms of the tweezer which act as hot and cold probes. The setup has the very important advantage of easy sample mounting and…

Purpose: The purpose of this paper is to identify the elements of education and training intervention that facilitate occupational transition intentions of undergraduates and encourage them to opt for entrepreneurial pursuit. Design/methodology/approach: The study, conducted in India, employed the nominal group technique (NGT) -- A systems science…

In this article I present some notes and reflections on possible ways to be adopted in teaching practice in Mathematics for the incorporation of meanings in teaching and learning of school mathematics in face of the cultural diversity in which the school is situated and constituted in the 21st century through the perspective of globalization. It…

In fashion design, pedagogy balancing a strong technical foundation with a more disruptive attitude during the ideation and development procedures provides the potential for diverse, emergent, aesthetically and critically poignant outputs. The ultimate goal in this is to offer a learning environment that is inclusive and accesses dormant design…

Utilizing the perspective of finite mixture modeling, this note considers whether a finding of a plausible one-parameter logistic model could be spurious for a population with substantial unobserved heterogeneity. A theoretically and empirically important setting is discussed involving the mixture of two latent classes, with the less restrictive…

There is an increasing demand in the field of science education for the incorporation of philosophical and sociological aspects that are related to the scientific enterprise in school curricula, to the extent that the incorporation of these aspects is now considered a necessity. Several of these aspects can be categorised within the framework of…

In 1932 Dewey and Tufts issued an extensively revised edition of their famous Ethics of 1908. Both versions are now available as public domain resources on the Internet, and teachers are likely to assign the second edition, since it reflects the authors' mature views. However, at least as regards Dewey's treatment of virtue, I argue that the…

The concept of educational questions has often been taken up topically, or as a related component to topics within philosophy of education. The rabbit hole approach provides a new perspective for attempting to discover the characteristics of educational questions and to engage with six authors, Biestra, Bingham, LeGrange, Andreotti, Saeverot and…
