In this article we consider the well-known demonstration of friction by two interleaved books. We consider a factor that has not been part of the popular explanation--atmospheric pressure. We provide three control experiments to demonstrate the role of atmospheric pressure in the two-book experiment and an additional simple demonstration of the…

The present article gravitates around the radical dilemma in which the evolution of the current human civilization has placed us. This route derives from certain global problems, such as most notably climate change, which have exacerbated the magnitude and complexity of the known socio-environmental problems. Avoiding the most extreme scenarios…

The goals for this study were to examine principals' perceptions regarding their own supervision and evaluation and compare to superintendents' perceptions regarding the supervision and evaluation of principals. Three research questions guided the inquiry: (1) What are the perceptions of principal and superintendents' regarding their own…

Recently there has been increasing emphasis on co-teaching experiences for teacher candidates. Despite the significance of collaboration between cooperating teachers and student teachers, limited empirical attention has focused on student teachers' co-teaching experiences. The following study utilized survey data to ascertain if student teachers'…

It can be hugely beneficial for teachers to 'buy in' an expert for a day in an area that they are focusing on. Children are inspired by a special visitor and it can provide a new perspective to a topic and invigorate and extend learning. The variety of workshops and visitors available is astonishing. Students can be transported to outer space or…

Complexity is among the main drivers that justify and guide the genesis and establishment of multi-, inter- and transdisciplinary approaches to the production and application of knowledge. Complexity can be read in the relatively canonical taxonomy of these concepts that structure epistemological reflections on the dynamics of knowledge production…

Questions of how to support students in conversation across and about different perspectives regularly appear in discussions about civic engagement. Students with clear political positions and a desire to engage with political institutions, however, are themselves a rarified group on many campuses. The gulf between students who seek to engage…

All teachers can benefit from peer coaching because it provides opportunities for them to grow in their craft by promoting collaborations, observations, feedback, and support from peers. The purpose of this study was to examine the impact of peer coaching on teacher instructional practices, in the areas of preparation for instruction and teacher…

When estimating an average treatment effect with observational data, it's possible to get an unbiased estimate of the causal effect if all confounding variables are observed and reliably measured. In education, confounding variables are often latent constructs. Covariate selection methods used in causal inference applications assume that all…

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…

While new ideas and innovative programs and pedagogies are exciting, the simplest methods are often the most effective. In "Doing What Works", author Chris Weber outlines ten practical, common-sense practices proven to transform student learning and propel school success. Each chapter includes examples from real school leaders and…

The motivation behind this examination is to present the theoretical structure of Modeling Activities, which is believed to be a vital device for mathematics instruction. Modeling activities are defined as activities to figure out complex problems faced in real life situations that require the creation of a mathematical model as a product. In…

If learning is a motor, student engagement is the key. But when teaching students with ADHD and other attention challenges, sometimes even the most finely tuned classroom can sputter. "Teach for Attention!" is your tool belt of teaching strategies for students with ADHD, low self-confidence, distraction, and other attention challenges.…

This study examined the role, importance and function of "saz semais" and "pesrevs" in cello teaching. It also examined the title and order of the pieces used in teaching, challenges experienced in the teaching of these pieces and suggestions for solutions. This study utilized phenomenological methodology. As a purposeful…

When latent variables are used as outcomes in regression analysis, a common approach that is used to solve the ignored measurement error issue is to take a multilevel perspective on item response modeling (IRT). Although recent computational advancement allow efficient and accurate estimation of multilevel IRT models, we argue that a two-stage…
