Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with poorly understood etiology. Many maternal exposures during pregnancy and breastfeeding potentially interfere with neurodevelopment. Using data from two age- and sex-matched case-control studies in Jamaica (n = 298 pairs), results of conditional logistic regression…

Virtual laboratory simulations are commercially available to train students; these creative resources are available to complete remotely without traditional time and safety restrictions of laboratory-based practical classes. We introduced a Health and Safety virtual laboratory simulation to a core large first-year science module. Having surveyed…

Occupational training is a crucial feature in enhancing workforce efficiency and the expertise involved in any profession. This is carried out through a variety of ways such as institutional training, basic instructions, excursions, industrial training, laboratory lessons, workshop operations, field studies, intensive problem-solving based…

Background:A 2011 nationwide school pandemic preparedness study found schools to be deficient. We examined the impact of a school nurse educational intervention aimed at improving K-12 school biological event preparedness. Mehods: Missouri Association of School Nurses (MASN) members were e-mailed a survey link in fall 2013 (ie, preintervention),…

The necessity of an adequate scientific literacy among the population in general and students in particular is a fact. Two of the main obstacles in science education that hinder it are the lack of connection between the contents worked in class and the students' day-to-day, and the misunderstanding of scientific language. In the present study, a…

The Roma people are the largest stateless population in Central and Eastern (CEE) Europe and face a disproportionate amount of environmental health disparities likely due to a long history of discrimination and stigmatization. Using qualitative research methodology and community-based participatory research methods, we aimed to gain a more nuanced…

There is evidence indicating that students are rarely asked about what they want to learn, but when they are asked, the students readily identify topics of personal relevance with a hands-on component. They want topics that are curiosity-based and not knowledge based. This paper draws on data that gave voice to 199 students studying geography and…

In Australia, the impacts of urbanisation and human activity are evident in increased waste generation and the emissions of metals into the air, land or water. Metals that have accumulated in urban soils almost exclusively anthropogenically can persist for long periods in the environment. Anthropogenic waste emissions containing heavy metals are a…

The 21st -century learning paradigm requires teachers to provide teaching materials that can develop students' thinking skills. This research aims to determine the effect of the web module science integrated local batik potential toward the thinking ability of seventh-grade students of junior high school. The research method used was…

Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…

School leaders across the United States face the challenge of creating safe and secure environments across their campuses in a way that helps promote the achievement of schools' educational objectives. To help them meet this challenge, the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency asked the Homeland…

Public school facilities primarily serve an educational role, and they also serve a civic role as voting places and emergency shelters. School districts collectively spend tens of billions of dollars each year on facilities construction needs at the nearly 100,000 K-12 public schools nationwide. About half (an estimated 54 percent) of public…

The general objective of this study was to analyze the development and implementation process of a waste management project (WMP) at a public school in the city of Porto Alegre in the state of Rio Grande do Sul, Brazil, that offers a course for chemistry technicians. To that end, an initial diagnostic analysis of the commonly produced waste from…

Current research describes a four-category scheme of Autism Spectrum Disorder (ASD) onset: early, regressive, plateau, delay + regression. To replicate prevalence of different onset types, ASD onset (per the "Autism Diagnostic Interview-Revised") was examined in a large North American sample; for a subset, parents' causal beliefs were…

An increasing evidence supports the role of industrial chemicals as contributors to the development of neurobehavioral disorders, including autism spectrum disorders, whose prevalence has progressively increased in recent years. Heavy metals, in particular, are recognized as neurodevelopmental toxins since they can be responsible of fetal damages…
