Over the last several years, a growing number of cities have invested in early care and education for 3- and 4-year-old children, known as "preschool." This paper aims to aid cities in planning preschool programs by outlining a range of factors to consider. We largely do not make recommendations, but rather try to identify a range of…

In this article, the authors propose to enhance the syllabus for economic courses with economic explanations. They argue that providing economic rationale for course policies can increase student interest in the course and at the same time positively affect student attitude toward course policies. The authors describe practical strategies for…

Bad smells affect maintainability and performance of model-to-model transformations. There are studies that define a set of transformation bad smells, and some of them propose techniques to recognize and--according to their complexity--fix them in a (semi)automated way. In academia it is necessary to make students aware of this subject and provide…

There has been an increased frequency of leadership courses being taught online. Scant research exists that describes effective practices for teaching leadership online. This application brief describes an assignment, the "Real Life Leader in the Mirror" given to undergraduate students in an online personal leadership course as an end of…

Ferdowsi's Shahnameh and Homer's Iliad are among the first literary masterpieces of Iran and Greece. These teachings include the educational teachings of Zal and Roudabeh, and Paris and Helen.

The relationship between diversity and creativity can be seen as paradoxical. A diversity of perspectives should be advantageous for collaborative creativity, yet its benefits are often offset by adverse social processes. One suggestion for overcoming these negative effects is perspective taking. We compared four dyads with low scores on trait…

Statistical methods are indispensable to the practice of science. But statistical hypothesis testing can seem daunting, with P-values, null hypotheses, and the concept of statistical significance. This article explains the concepts associated with statistical hypothesis testing using the story of "the lady tasting tea," then walks the…

Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study.

Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…

There is a broad consensus that beginning teachers of mathematics need a strong foundation in mathematical knowledge for teaching (MKT), defined as the mathematical knowledge required to recognize, understand, and respond to the mathematical work of teaching one must engage in. One recurrent challenge in teacher education is how to provide support…

Sometimes words can change the world, but more often, the stark realities of an unjust world can fail to bend to even the most beautifully chosen words. In the face of long odds, the impulse to write and share words, in any…

The field of early childhood education (ECE) is currently unable to reach consensus on the extent to which ECE should be based on child development. One manifestation of this situation is the dilemma that early educators purportedly face between teaching the whole child and the curriculum, between developmentally appropriate practice (DAP) and…
