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"…

This paper demonstrates that an informal field trip can have a lasting impact upon aspects of learning in a primary school context. Specifically, we consider the longer term impact of an informal trip to a rocky shore upon scores achieved in literacy assessments taking place five months after a relevant five months after a fieldwork. Pupils…

An efficient laboratory experiment has been developed for undergraduate students to conduct hydrogen-deuterium (H-D) exchange of resorcinol by electrophilic aromatic substitution using D[subscript 2]O and a catalytic amount of H[subscript 2]SO[subscript 4]. The resulting labeled product is characterized by [superscript 1]H NMR. Students also…

Links between young children's everyday use of mindful conversational skills and their success on laboratory tests of theory of mind understanding (ToM) were evaluated. Using published scales, teachers rated the conversational behavior and shyness of 129 children aged 60 to 101 months (M = 78·8 months) who were in their first years of primary…

A laboratory experiment that introduces fluorometry of chlorophyll "a" at the general chemistry level is described. The use of thin-layer chromatography to isolate chlorophyll "a" from spirulina and leaf matter enables quantification of small amounts of chlorophyll "a" via fluorometry. Student results were reasonably…

A laboratory exercise is described that helps students learn about lipid self-assembly by making vesicles under different solution conditions. Concepts covering the chemical properties of different lipids, the dynamics of lipids, and vesicle stability are explored. Further, the described protocol is easy and cheap to implement. One to two…

Mechanochemical syntheses avoid or considerably reduce the use of reaction solvents, thus providing green chemistry synthetic alternatives that are both environmentally friendly and economically advantageous. The increased solid-state reactivity generated by mechanical energy imparted to the reactants by grinding or milling can offer alternative…

Recent research on adult German suggests that speakers use particular pitch accent types to signal the information status of discourse referents. This study investigates to what extent German five- and seven-year-olds have acquired this mapping. Semi-natural speech data was obtained from a picture-elicited narration task in which the information…

High-resolution solid-state NMR (SSNMR) spectroscopy has many advantages as a tool to characterize solid-phase material that finds applications in polymer chemistry, nanotechnology, materials science, biomolecular structure determination, and others, including the pharmaceutical industry. The technology associated with achieving high resolution…

Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool for examining the charge of proteins in solution. The charge can be manipulated through choice of solvent and pH. Furthermore, solution-accessible, protonated lysine side chains can be specifically tagged with 18-crown-6 ether to form noncovalent adducts. Chemical derivatization…
