The COVID-19 crisis has demonstrated the importance of being able to understand complex computational models for everyday life. To make sense of the evolving predictive models of the COVID-19 pandemic, global citizens need to have a firm grasp of both systems thinking (ST) and computational thinking (CT). ST is the ability to understand a problem…

By now the slogan of the National Trust for Historic Preservation that "the greenest building is the one already built" is widely known. In an era of increased environmental awareness and rising fuel prices, however, the question is how can historic building stock be made more energy efficient in a manner respectful of its historic…

Switched-mode power supplies (SMPS) are becoming an essential part of many electronic systems as the industry drives toward miniaturization and energy efficiency. However, practical SMPS design courses are seldom offered. In this paper, a generalized MATLAB/SIMULINK modeling technique is first presented. A proposed practical SMPS design course at…

Fast-forward fifty years (from the 1960s) to 2010, and the question becomes, why should we consider renovating the 1960s school era buildings, especially if they maybe lacking culturally, economically and technologically from the present? Isn't it easier to create the 2010 school model as a new facility and build what is needed from the ground up?…

Anything that can capture the interest of students can be used to enhance the teaching of physics, and sport is practised, watched and followed fanatically by almost every young person. At the same time, in recent years, a wealth of research data has become available from the field of sports science. The purpose of this article is to draw from…

Climate change, rising energy costs, and other dilemmas raise the prospect for major change in energy-ecology-society relations. Two prominent proposals for change include: a nuclear power renaissance; and mega-scale renewable energy development. Both suggest that modern society will receive a rising stream of less CO2-rich kilowatt-hours, so that…

Since the mid-1980s, power sector liberalization has been embraced at different levels in the East Asian countries of China, Japan, South Korea and Taiwan. The dominant rationale underlying power liberalization has been a quest for efficiency improvements, to be achieved by substituting private market activity for public regulations and by opening…

Energy costs are a school district's second highest expenditure after personnel. Public schools currently spend more than $8 billion per year for energy. School energy expenditures rose, on average, 20 percent per year between 2000 and 2002--and the costs continue to rise. Natural gas prices alone increased 14 percent annually between 2003 and…

Many people narrowly focus on energy efficiency when defining a "high-performance" school--a school building that is economical with respect to heating, cooling, and electric lighting. That is certainly true, but in the broadest terms, a high-performance school is designed to minimize reliance on fossil fuels--and provide a comfortable, healthful,…

The Afterschool Alliance and MetLife Foundation are proud to celebrate a fifth round of the MetLife Foundation Afterschool Innovator Awards. For the past five years, we have collaborated to highlight the work of quality afterschool programs that support children, families and communities across the nation. This compendium is a compilation of four…

The Total Energy Management (TEM) for Minnesota Schools program is a unified, planned approach to reducing the energy use and costs of an individual school or school district. The program is designed to increase energy awareness and improve school energy efficiency through: (1) careful energy accounting; (2) changes in operations and maintenance…

Two projects, the Milford (Pennsylvania) Reservation Solar Conservation Center and Prototype Passive Solar Townhouses, are designed for solar energy--one as a learning center, the other as urban infill housing. (Author/MLF)

Develops simple numerical estimates to quantify a variety of energy economics issues, including among others, a modified Verhulst equation (considers effect of finite resources on petroleum) for supply/demand economics and a phenomenological model for market penetration also presents an analysis of economic returns of an energy conservation…

An energy analysis model is provided for college administrators in which information from their utility bills is used to measure the amount of energy saved and to determine the fuel costs avoided when they undertake an energy conservation program. Because the model explicitly takes into account variations in weather, it provides an essential tool…

Designed for school personnel, the booklet suggests a framework for providing programs for the gifted and talented (G/T) students that will develop a concern for environmental problems. After a description of environmental education and a rationale for its place in the classroom, descriptions of three Indiana programs for G/T students are…
