We propose a series of experiments involving balance readings of an object naturally floating or forced to be partially or fully immersed in water contained in a beaker sitting on an electronic scale balance. Students were asked to predict, observe and explain each case. The teacher facilitated the learning by asking probing questions, giving…

In this paper, I explore how histories of colonialism are integral to the Euro-Western idea of wilderness at the heart of much outdoor environmental education. In the context of canoe tripping, I speculate about why the politics of land rarely enters into teaching on the land. Finally, because learning from difficult knowledge often troubles the…

This descriptive, exploratory study focused on how institutions of higher education have used the United States Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED[R]) Green Building Rating system. It employed statistical methods to assess which types of universities have used LEED, what ratings they earned, and…

As part of a Teachers' International Professional Development (TIPD) group, ten primary science teachers, including Advanced Skills Teachers (ASTs), local authority consultants and science coordinators, representing seven schools in Islington, London, were invited to visit the island of Dominica in the Caribbean. The aim of the trip was to: (1)…

The presence of microorganisms on common classroom contact surfaces (fomites) was determined to identify the areas most likely to become contaminated. Six elementary classrooms were divided into control and intervention groups (cleaned daily with a quaternary ammonium wipe) and tested for heterotrophic bacteria. Three classrooms were also tested…

As part of an integrative learning experience at the end of a sophomore Calculus II course at the United States Military Academy, this project served as a multidisciplinary problem-solving exercise that explored the connections among mathematics, biology, and other fields of study. During a seven-lesson block of instruction, this module was…

This project was used in a mathematical modeling and introduction to differential equations course for first-year college students. The students worked in two-person groups and were given three weeks to complete the project. Students were given this project three weeks into the course, after basic first order linear differential equation and…

During Cave Week, more than 200 students explore a simulated cave environment and participate in cave-related activities. Active cavers from a local club bring in equipment and photos and speak about their caving experiences. As student groups explore the simulated cave, other groups participate in different activities where they can create bat…

Agricultural Engineering has transformed agricultural practices from subsistence level to medium and large-scale production via mechanisation in the developed nations. This has reduced the labour force requirements in agriculture; increased production levels and efficiency, product shelf life and product quality; and resulted into…

The world's population is growing by about 80 million people a year, implying an estimated increased freshwater demand of about 64 billion cubic meters annually (World Water Assessment Programme, 2009, Water in a Changing World: United Nations World Water Development Report 3, Chap. 1, p. 3-21). Groundwater depletion, which reduces the amount of…

An analysis of physical geology textbooks used in introductory courses shows that there is a systematic lack of clarity regarding flood risk. Some problems originate from confusion relating to statistical terms such as "100-year flood" and "100-year floodplain." However, the main problem is conceptual: statistics such as return…

Local news media help shape the agendas from which new policies emerge. Furthermore, local media help determine public understanding of complex issues. Media should inform citizens and policymakers on important policy issues. This study uses a content analysis of 11 newspapers to understand the manner in which reporters covered a specific…

This paper reports some findings from an investigation of educational practice in ten (formal and informal) education for sustainability (EfS) initiatives, to characterise exemplary practice in school and community education for sustainability, considered crucial to Australia's future. The study focused on rural/regional Australia, specifically…
