Educator beliefs and organizational constraints: Factors that influence informal education about fish consumption advisories in a southeastern US state.

All US states, and many countries around the world, have waterways with environmental health advisories intended to protect individuals from harmful chemicals in fish, yet little is known about how informal science educators, even those who engage anglers along waterways, incorporate advisory information into their educational activities. This study, grounded in environmental health literacy, investigated the practices, knowledge, and beliefs of 24 informal educators housed in varied agencies and organizations in a southeastern US state. Participants described a range of educational activities and identified organizational constraints on their education about fish consumption advisories, which varied by organization type.

Contextual Choices in Online Physics Problems: Promising Insights Into Closing the Gender Gap.

Throughout the world, female students are less likely than males to take advanced physics courses. This mixed-methods study uses a concurrent, nested design to study an online homework intervention designed to address choice and achievement. A choice of three different contexts (biological, sports, and traditional) were offered to students for each physics problem, intending to stimulate females' interest and enhance achievement.

Engaging Latino farmworkers in the development of symbols to improve pesticide safety and health education and risk communication.

The working and living environments of farmworkers put them and their families at risk for pesticide exposure and, consequently, immediate and long-term health effects. In this study, visual materials for a pesticide toxicology safety and health curriculum were constructed by engaging farmworkers in various stages of symbol development. Twenty-seven farmworkers in two states participated in this descriptive case study through focused small group discussions and interviews.

The Pesticide Risk Beliefs Inventory: a quantitative instrument for the assessment of beliefs about pesticide risks.

Recent media attention has focused on the risks that agricultural pesticides pose to the environment and human health; thus, these topics provide focal areas for scientists and science educators to enhance public understanding of basic toxicology concepts. This study details the development of a quantitative inventory to gauge pesticide risk beliefs. The goal of the inventory was to characterize misconceptions and knowledge gaps, as well as expert-like beliefs, concerning pesticide risk.

Random Responding from Participants is a Threat to the Validity of Social Science Research Results.

Research in the social sciences often relies upon the motivation and goodwill of research participants (e.g., teachers, students) to do their best on low stakes assessments of the effects of interventions.
