Ferraro and Taylor (2005) and Potter and Sanders (2012) have sparked a debate about the definition of opportunity cost (OC). This is, of course, ostensibly a very basic term, but Ferraro and Taylor said that most economists do not readily know its correct definition, and Potter and Sanders argued that this can be explained by the fact that there…

U.S. students have consistently demonstrated poor performance in spatial reasoning in standardized testing (e.g., National Assessment of Educational Progress). One possible reason is students' lack of conceptual understanding of measurement concepts (length, area, volume, capacity). This paper describes different ways that mathematics textbooks…

Despite a vast amount of research into school bullying and the widespread implementation of anti-bullying policies and programs, large numbers of students continue to report that they are routinely subjected to bullying by their peers. In this theoretical article, I argue that part of the problem is that there has been a lack of critical…

For a few decades, map skills stay at the forefront of not only geographers' and geographic educators' research interest. To identify what has already been accomplished, where the research currently stands and where the potential for future studies lies, a review of the literature was carried out. Specifically, this comprehensive synthesis of map…

Purpose: This paper aims to report and discuss findings from the first exploratory phase of a research project that examined how and in what ways the practice of vocational student work-placement contributes to innovation in host organisations. The focus of the paper is on identifying and clarifying how innovation is understood in this context and…

One of the questions being asked in schools is the extent to which Geography can be considered a STEM (Science, Technology, Engineering, and Mathematics) subject. While such a question might be driven by those strategic opportunists seeking to elevate the status of the subject within the school's curriculum, or as a means of leveraging an increase…

Educational psychology is replete with verbal or qualitative definitions through which students can be considered members of categories, such as learning disabled, autistic, or gifted. These conceptions carry quantitative implications regarding the incidence rates of the phenomena they describe. To be scientifically useful, such definitions should…

This paper describes a research project implemented in a course of Real Analysis II. The aim of this project is to analyse students' comprehension of the limiting behaviour of a function from "R"[superscript 2] to "R" at a point "P"[subscript 0] focusing on the formal definitions. Alternative definitions and other…

We analyze the process of constructing a definition within the theoretical framework of "Abstraction in Context." Pairs of students were engaged in a task designed to engender a need for a definition of a tangent to a graph at a given point, and lead to constructing a definition following that need. The results of our analysis point to…

There is much concern in South Africa about the poor performance of learners in mathematics, particularly in geometry. The aim of this research was to explore the understanding of basic geometry concepts by grade 10 and grade 11 learners in terms of the van Hiele's levels of geometry thinking. The participants of the research were 147 learners…

This chapter is structured for teaching young learners with physical (orthopedic) disabilities in special education. Orthopedic impairments encompass a range of disabling conditions. Orthopedic impairments are typically grouped into three main categories: (1) congenital anomalies (CA) such as absence of a member or clubfoot, (2) impairments caused…

In interdisciplinary education, metaphors often provide the epistemological clarity that is lacking in our definitions and theories of interdisciplinarity. The problem is that ineffective and unsubstantiated metaphors proliferate. We lack a root metaphor or shared world view of interdisciplinarity. Is it time that we move away from thinking in…

The present study examines how middle school students attending private schools in a major urban centre in India understand intelligence. The study focuses on mindset theory, which is a major framework in the literature on children's understandings of intelligence. Mindset theories distinguish individuals based on beliefs about the malleability of…

Decades of research related to the experience of postsecondary students who are adults, work full-time, or have other life roles have not led to agreement in the field regarding who is a "nontraditional" college student. This study leverages nationally representative data to illuminate shifts in this student population in the 21st…

Recent advances in Artificial Intelligence (AI) have sparked renewed interest in its potential to improve education. However, AI is a loose umbrella term that refers to a collection of methods, capabilities, and limitations--many of which are often not explicitly articulated by researchers, education technology companies, or other AI developers.…
