A 3D printer is used to prepare a variety of models representing potential energy as a function of two geometric coordinates. These models facilitate the teaching of structure-energy relationships in molecular conformations and in chemical reactions.

This article reports on the results of a research project in which 18 teacher educators in three countries-Australia, The Netherlands, and United Kingdom-were interviewed about their experiences of working in the so-called "third space" between schools and universities, particularly in relation to the practicum, or field supervision.…

Additive manufacturing, commonly known as 3D printing, is gaining popularity in a variety of applications and has recently become routinely available. Today, 3D printing services are not only found in engineering design labs and through online companies, but also in university libraries offering student access. In addition, affordable options for…

The Holy Cross Chemistry Department has designed and implemented an experiment on buffers as part of our Discovery Chemistry curriculum. The pedagogical philosophy of Discovery Chemistry is to make the laboratory the focal point of learning for students in their first two years of undergraduate instruction. We first pose questions in prelaboratory…

Tangible models help students and researchers visualize chemical structures in three dimensions (3D). 3D printing offers a unique and straightforward approach to fabricate plastic 3D models of molecules and extended solids. In this article, we prepared a series of digital 3D design files of molecular structures that will be useful for teaching…

There is growing interest in the professional development of teacher educators as the demands, expectations, and requirements of teacher education increasingly come under scrutiny. The manner in which teacher educators learn to traverse their world of work in the development of their knowledge, skills, and ability is important. This article…

In recent years, a small but growing strand of research has investigated ways of focusing teachers' professional education on "core" or "high leverage" practices of teaching. These efforts are easily conflated with other initiatives to develop "practice-focused" teacher education, raising questions about what…

The Reconstructed Cohort Method is often used to examine the status of national education. However, this method does not account for individual details and we know little about the status of school enrolments by tracking individual students from entrance until dropout or graduation. This study employs the True Cohort Method to analyse data for…

Scottish educational policy advocates the benefits of collaborative learning as a way of developing critical life skills, across the primary curriculum. In this paper, the rationale for collaborative learning, and specifically the Critical Skills (CS) approach, is considered along with an account of the perspectives of primary teachers…

This paper examines a Steiner Waldorf Perspective to School Readiness and applies that international ideology to educational practice and curriculum policy in modern Ireland. The case for a later school start is championed with strong arguments underpinning the reasons why a later start is better in the long run for children's formal learning…

There is a growing need for articulation of the theoretical framework underpinning performance as a learning medium in heritage sites and for an in-depth insight into the children's experiences therein. The aim of this paper is to explore some of the themes that emerged from researching participatory theatre in a historic house as experienced…

The purpose of this study is to explore the knowledge demands of teacher educators as they teach disciplinary content to preservice elementary teachers, specifically in mathematics, and to understand how such knowledge is different from that used by K-12 teachers. Drawing from a database including teaching and learning artifacts from five…

Video is being used more widely in professional development to help teachers learn to notice and systematically analyze teaching practice. Video captures the authenticity and complexity of teaching and can promote the examination of classroom interactions in a deliberate and focused way. However, simply viewing video does not ensure teacher…

While few would disagree that a key component of educating teachers to teach happens on the job, research rarely explores the schoolhouse as a site for teacher education. This study thus focuses on inservice as distinct from preservice teacher education and explores how beginning teachers' learning about mathematics and literacy instruction…

Ion exchange chromatography is an important technique in the separation of charged species, particularly in biological, inorganic, and environmental samples. In this experiment, students are supplied with a mixture of two substitution-inert complex ions. They separate the complexes by ion exchange chromatography using a "flash"…
