Clustered data structures are common in many areas of educational and psychological research (e.g., students clustered in schools, patients clustered by clinician). In the course of conducting research, questions are often administered to obtain scores reflecting latent constructs. Multilevel measurement models (MLMMs) allow for modeling…

Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

"Making Room for Change" is an educational book that will be valuable to anyone involved in secondary education. The book will provide clear examples, research, and personal reflections of how building in flexible time can be different from the historic middle and high school scheduling models. Educators of all ages and levels of…

This timely volume sets out the author's novel concept of the Organic model of internationalisation, developed using participants' perceptions, lived experiences, and recommendations for a better sustainable future of HE, and explores its broader application in the context of higher education. Using the qualitative IPA (Interpretative…

The purpose of this article is twofold. The first is to provide evaluative information on the recovery of model parameters and their standard errors for the two-parameter item response theory (IRT) model using different estimation methods by Mplus. The second is to provide easily accessible information for practitioners, instructors, and students…

One econometric rule of thumb is that greater dispersion in observations of the independent variable improves estimates of regression coefficients and therefore produces better results, i.e., lower standard errors of the estimates. Nevertheless, students often seem to mistrust precisely the observations that contribute the most to this greater…

In thinking about teens and online risks, school librarians need to know researchers generally agree that, despite the popular image of pedophiles and criminals lurking online waiting to harm innocent young people, in reality social media use is only about as risky as most everyday social interactions in the offline world (Agosto and Abbas 2013).…

This article provides both an experiment and a framework for discussion that students can use to compare the efficiency of producing ethanol by using corn versus sugarcane as a raw material.

Attending a professional conference is an effective way to explore and advance knowledge, skills, and careers. For graduate students, attending a conference is an effective way to explore academic fields and new professions. However, attending a professional conference requires precious resources--time and money--so the decision to attend, or not,…

We consider the effect on estimation of simultaneous variable centering and interaction effects in linear regression. We technically define, review, and amplify many of the statistical issues for interaction models with centering in order to create a useful and compact reference for teachers, students, and applied researchers. In addition, we…

Embarking in an educational research paper is one of the daunting processes any scholar can go through. And the process is even harder for novice education students who wander through the plethora of terminology, styles and paradigms trying to figure out their way in that jungle called educational research. The following of the review presents the…

There is currently a rapidly growing interest in inquiry learning and an emerging consensus among researchers that, particularly when supported by technology, it can be a significant vehicle for developing higher order thinking skills. Inquiry learning methods also offer learners meaningful and productive approaches to the development of their…

One of the greatest mysteries of ancient times is how the Egyptians managed to raise huge obelisks using very simple technology. This remarkable task has puzzled engineers for thousand of years. After failing to raise an obelisk with simple machines, such as levers and pulleys, a team of modern engineers solved the mystery using a sandpit and the…

To tackle the complexity of issues associated with homelessness, an interdisciplinary lens with direct input from service providers and community members is necessary. Within a community-university partnership between a larger inner-city multiservice shelter serving the homeless population, and faculties of social work and nursing in a Canadian…

This book should be read by anyone concerned about the future of education in the United States. It was written for students, parents, educators, administrators, and policy makers because it will require effort from all these individuals to create meaningful change in the education system. This book discusses why the education system needs to…
