The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

General chemistry students need to understand the concept of intermolecular forces and use them to predict the properties of materials. To do this, they must create symbolic representations of molecules, relate these to physical observations, and explain them using submicroscopic theoretical constructs. When these concepts are taught separately,…

Subjectification in environmental movement education comprises an influx of more-than-human 'others,' including the classical elements: air, water, earth, fire. In this conceptual article, I consider what environmental movement education research, which includes inquiring into processes of political subjectification, might entail, when thinking…

This paper summarizes an exploratory study probing perspectives of pesticide applicators and educators regarding pesticide licensing and safety training in Idaho. The purpose of the study was to identify lines of inquiry concerning critical learning components for pesticide worker safety. Information was gathered about training practices for…

At many universities, silver nitrate is used in teaching laboratories, and a resulting waste product is often silver chloride. Silver chloride is not a compound that can be discarded into a sink as it has harmful effects to the environment; however, commercial waste disposal is costly, and replacement of the silver nitrate reagent is expensive.…

The objectives of this paper were to 1) study the learning model of the smart crematorium system, 2) create a learning manual on smart cremation management, and 3) promote the development of learning for undertakers to use the smart crematorium. This was mixed method research with qualitative research and action research as parts of the conduct of…

Lead poisoning has well-known impacts for the developing brain of young children, with a large literature documenting the negative effects of elevated blood lead levels on academic and behavioral outcomes. In April of 2014, the municipal water source in Flint, Michigan was changed, causing lead from aging pipes to leach into the city's drinking…

Background: Waterpipe tobacco smoking is associated with many negative health outcomes due to toxicants produced by heating the tobacco using charcoal or electrical heaters. Little is known about how young adult waterpipe tobacco smokers perceive harms of these heating sources. Aims: To examine young adult waterpipe tobacco smokers' perceived…

An environmental chemistry service-learning project was implemented by Greenville University in coordination with the local county health department to test the quality of well water for residents in a five-county region of southern Illinois. Well owners attended a student run well water testing "kickoff meeting", received testing kits,…

Further investigation is needed to determine the specific laboratory management needs of agricultural education teachers. The theoretical foundation which guided this study was Bandura's theory of self-efficacy (1997). To further align this theory with this study, researchers explored the beliefs and one's capabilities to organize and excute the…

Habituation is a non-associative form of learning characterized by a decremented response to repeated stimulation. It is typically framed as a process of selective attention, allowing animals to ignore irrelevant stimuli in order to free up limited cognitive resources. However, habituation can also occur to threatening and toxic stimuli,…

Home-based care facilities provide basic healthcare services to people too sick or frail to access formal clinics and hospitals. These facilities produce 'healthcare risk waste' which must be managed responsibly, and it is the work of Environmental Health Practitioners working within municipalities to ensure that the waste produced by home-based…

Purpose: A growing body of evidence suggests that military service members and military veterans are at risk for deficits in central auditory processing. Risk factors include exposure to blast, neurotrauma, hazardous noise, and ototoxicants. We overview these risk factors and comorbidities, address implications for clinical assessment and care of…

Elevated blood lead levels in children--even at very low levels--contribute to learning deficits and behavioral and attentional problems. No federal law requires the testing of drinking water in schools, and recent reports from the Government Accountability Office reveal a dearth of lead testing of water or paint in school buildings. This NASBE…

A problem-based learning (PBL) methodology was implemented to a project, whose main objectives were to discuss and apply the Twelve Principles of Green Chemistry to the study of poly(vinyl alcohol)'s cross-linking reaction with dicarboxylic acids. The five participating students were oriented to be responsible for their own learning and the…
