This study investigated the development of the concept of variables in middle grades mathematics textbooks during four eras of mathematics education in the United States. Findings revealed that each of the middle grades mathematics curricula examined used variables, but in varied proportions and levels of complexity. Formal definitions for…

Numerous articles have been published that address problems encountered in teaching basic concepts of chemistry such as the atomic mass unit, Avogadro's number, and the mole. The origin of these problems is found in the concept definitions. If these definitions are adjusted for teaching purposes, understanding could be improved. In the present…

This fMRI study was conducted to investigate whether language semantics is processed even when attention is not explicitly directed to word meanings. In the "unattended" condition, the subjects performed a visual detection task while hearing semantically related and unrelated word pairs. In the "phoneme" condition, the subjects made phoneme…

Since the mid-1990s, however, the popularity, diversity, and application of virtual worlds have spread rapidly. As a result, existing taxonomies and topologies increasingly are becoming less effective at being able to classify and organize the growing diversification of content available in today's virtual worlds. This article presents the…

The field of early childhood education continues to grapple with the issue of understanding quality in classrooms.

This essay will focus on the interdisciplinary broadening of…

In a previous study, Puk and Stibbards (2010) demonstrated that a cohort of teacher candidates entering into an ecological literacy, Bachelor of Education program had very immature understanding of complex ecological concepts. Specifically, written definitions were either absent entirely, very vague, or missing essential criterial attributes, as…

IUPAC gives several different definitions of oxidation: loss of electrons, increase in oxidation state, loss of hydrogen, or gain of oxygen. Most introductory or general chemistry textbooks use all of these definitions at one time or another, which can lead to some confusion in the minds of first-year chemistry students. Some paradoxical…

Circles are symbols of interconnectedness. Behavioral circles can be vicious or virtuous. Many American Indians are caught in a vicious circle of exclusion from the purported benefits of Westernization, entrapment in its negative elements, and the ongoing undermining of their culture and thus their identities.

Instructors differed in…

Learning to learn (L2L) is an important component of lifelong learning. First, the article discusses various possible definitions of L2L and identifies the most comprehensible definition, which provides the basis for the analysis. Subsequently, it presents the results of a pilot study carried out in the early stage of primary education. This study…
