A multipart laboratory activity introducing microbeads was created to meet engineering and engineering design practices consistent with new Next Generation Science Standards (NGSS). Microbeads are a current topic of concern as they have been found to cause adverse impacts in both marine and freshwater systems resulting in multiple states proposing…

The effective management of physical resources significantly impacts on the quality of teaching and learning in schools. The procurement, utilization and maintenance of physical resources through organized structures, well-designed policies and rigid processes are critical for quality education. According to the South African Schools Act 1996, a…

In this contribution, I explore how critical pedagogical perspectives can inspire adult and community education practices. The central argument is that today, in contrast with the heydays of emancipatory practices and theories, the classical critical approaches need reconsideration. The paper explores how these approaches sometimes have a…

A laboratory experiment was designed for undergraduate students, in which the outcome of an easy single-step organic synthesis with well-defined conditions was not elucidated until the end of the exercise. In class, students predict and discuss the possible products using their knowledge of reaction mechanisms. In the laboratory, they learn how to…

Four academic deans investigated when and how they used interpersonal/negotiating skills to function effectively in their positions. For two full weeks, the deans coded their on-the-job interactions during scheduled meetings, informal meetings, spontaneous encounters/meetings, telephone calls, and select email. Analyses revealed that the…

Sound is typically thought of something that is heard. Can it be seen or felt? Most students experience the noises that surround them in everyday life, but few stop to think about what sound is, how it travels, and the biological challenges associated with perceiving sound. Since students are already familiar with everyday sounds, inquiry-based…

Little is known about Australian high-performance school-age athletes' experiences as victims of the tall poppy syndrome. Tall poppies are successful individuals bullied by those who are less successful in order to "normalize them." Nineteen current or previous national or international high-performance school-age athletes were…

In this article I present some results from a 5-year longitudinal investigation with young students about the genesis of embodied, non-symbolic algebraic thinking and its progressive transition to culturally evolved forms of symbolic thinking. The investigation draws on a cultural-historical theory of teaching and learning--the theory of…

The aim of this study is to investigate learners' transforming participation as they enter and engage in a learning community. To do this, we investigated the micro-development of two students' learning and collaborative practices in the context of a unique learning community that was fostered within a graduate level course.…

The final topic in a series looking at financial management from a theoretical perspective, working capital management provides the focus of the current article. We investigate how three key axioms--the risk-return tradeoff, agency conflicts, and stockholder wealth maximization--relate to this activity that occupies much of the financial manager's…

The neural mechanisms used in tone rises and falls in Mandarin were investigated. Nine participants were scanned while they named one-character pictures that required rising or falling tone responses in Mandarin: the left insula and right putamen showed stronger activation between rising and falling tones; the left brainstem showed weaker…

In studies on auditory speech perception, participants are often asked to perform active tasks, e.g. decide whether the perceived sound is a speech sound or not. However, information about the stimulus, inherent in such tasks, may induce expectations that cause altered activations not only in the auditory cortex, but also in frontal areas such as…

Learning word-referent mappings is complex because the word and its referent tend to co-occur with multiple other words and potential referents. Such complexity has led to proposals for a host of constraints on learning, though how these constraints may interact has not yet been investigated in detail. In this paper, we investigated interactions…

Doctors often make decisions for their patients and predict their patients' preferences and decisions to customize advice to their particular situation. We investigated how doctors make decisions about medical treatments for their patients and themselves and how they predict their patients' decisions. We also studied whether these decisions and…

Few programs exist for after school care designed to support children with Autism Spectrum Disorder (ASD). Not only do parents often depend on after school care, but also children with ASD are likely to benefit from opportunities to generalize skills in an authentic setting and interact with typically developing peers. This lack of support occurs…
