This article focuses on farmers' use of literacy for individual decision-making on crop-water management and crop choices and investigates how farmer participants perceive the usefulness of Farmer Water School (FWS) training. It draws upon a study conducted with farmers of Kurnool district of Andhra Pradesh, India. This study has demonstrated that…

The flame test is a classical analytical method that is often used to teach students how to identify specific metals. However, some universities in developing countries have difficulties acquiring the sophisticated instrumentation needed to demonstrate how to identify and quantify metals. In this context, a method was developed based on the flame…

A general chemistry laboratory experiment using readily available chemicals is described to introduce college students to an exciting class of nanocomposite materials. In a one-step room temperature synthetic process, magnetite nanoparticles are embedded onto activated carbon matrix. The resultant nanocomposite has been shown to combine the…

This article describes an interrupted case study that intersperses information about diffusion and osmosis with content review and knowledge application questions, as well as a simple experiment that can be conducted without the use of a laboratory. The case study was developed for use in an introductory undergraduate biology course. The case…

This article summarizes a social mapping project conducted by the Environmental Education, Communication and Arts Research Group from the Federal University of Mato Grosso. The primary goals of the project were to map the vulnerable social groups of Mato Grosso, and identify the social and environmental conflicts that put them in situations of…

The destructive potential of one of nature's most destructive forces, the hurricane, is compared to one of human's most destructive devices, an atomic bomb. Both can create near absolute devastation at "ground zero". However, how do they really compare in terms of destructive energy? This discussion compares the energy, the…

In the United States, the phrase "goin' fishin'" is synonymous with taking a break and leaving everyday cares behind to go enjoy the outdoors, spend time with family or friends, and, if one is lucky, catch some tasty fish.

Throughout the world, people have to deal with the issues of global warming and other more direct consequences of environmental change. This paper considers how a local newspaper has an educative function in a small community in advising people of specific issues and learning how to deal with changing resources. Across the period of several months…

Though heterogeneous nucleation of liquid droplets on a smooth surface (such as a bathroom mirror) is a classical topic in nucleation theory, it is not well-known that this topic is actually a pedagogical example of heterogeneous catalysis: the one and only effect of the surface is to lower the activation Gibbs energy of droplet formation. In…

For many middle school students, connections between their lives and concepts like chemical reactivity, microbial contamination, and experimental sampling are not obvious. They may also feel that, even if there were connections, understanding the monitoring and quality of natural resources is something for grown-ups and beyond their…

The purpose of this study was to explore how examples used in teaching may influence elementary school students' conceptions of evaporation and boiling. To this end, the examples traditionally used to explain evaporation and boiling in Korean 4th grade science textbooks were analyzed. The functions of these published examples were explanation…

Building Technology graduates from Ghanaian Polytechnics seek employment in the construction industry, yet little information is known as to whether their tertiary education is really related to and meeting the actual needs of their prospective employers in the construction industry. The tracer study was conducted to ascertain the performance of…

Water is one of our most precious resources. However, for many in the United States, having fresh, safe drinking water is taken for granted, and due to this perceived lack of relevance, students may not fully appreciate the luxury of having safe running water--in the home. One approach to resolving water-quality issues in the United States may…

The emerging and expanding green economy has the potential to create not just jobs, but career opportunities across the United States as green manufacturing, green products, and green services fuel demand for workers at all skill levels. Community colleges are leading the way in defining and addressing these opportunities. They are: developing…

Informed by the results of a baseline research study of regional citizen knowledge and understanding concerning watershed issues, a team of university faculty and classroom teachers designed and implemented a water conservation education program to address lacking areas of watershed knowledge. The authors developed age-appropriate, hands-on…
