Although teaching of environmental physics and energy-related topics has increased in the last several years, only a small portion of that has been for non-science majors. Environmental physical science can be used to teach physics to non-science majors by applying learned physics concepts to current issues of interest such as climate change,…

We make a case for including difference equations, in particular the discrete logistic equation, in basic differential equations courses. Contrasting the behavior of discrete and continuous models enriches students' understanding of both modeling and differential equations. To facilitate sharing discrete population models with students, some…

Educational scholars, particularly those working in comparative education, have largely failed to recognise, let alone discuss, the impending finite-ness of global resources. The field continues to operate on an assumption of infinite resources, an implicit cultural horizon in place since at least the Western Enlightenment. It has missed the…

With a fertility rate that nearly triples the national average and increased political power that accompanies demographic growth, Haredi (ultra-Orthodox) Jews in Israel are becoming an increasingly important piece of the country's diverse national mosaic. This raises economic concerns: Haredi women earn low wages, while most Haredi men do not…

This paper introduces sigmoid or s-curve as a metaphor for describing the dynamics of change. We first encountered the s-curve as a description of a possible growth trajectory whereby populations become established, begin to flourish and the numbers increase rapidly until they reach some limit. At this point, the growth rate slows rapidly then…

In a world with an ever-increasing population, diminishing natural resources, and greater levels of consumption, sustainability has emerged as a critical concept and it encompasses everything from international policy to lifestyle changes to "green" technologies. While various aspects of sustainability have been adopted by schools and…

Many children with an immigrant background face enormous challenges at school: they need to quickly adjust to different academic expectations, learn in a new language, forge a social identity that incorporates both their background and their adopted country of residence--all while often under conflicting pressures from family and peers. These…

Al Bartlett's video "Arithmetic, Population, and Energy" spells out many of the complex issues related to energy use in our society. Bartlett makes the point that basic arithmetic is the fundamental obstacle preventing us from being able to grasp the relationships between energy consumption, population, and lifestyles. In an earlier…

China's one-child policy has been an unprecedented policy experiment in human history. Despite its significant achievements, the policy has induced equally significant potential problems. As problems of the one-child policy have been widely noticed and suggestions for adjustments are available, the leadership transition of China in 2012 and 2013…

The world is rapidly becoming more educated at higher education level. In nearly all countries with per capita GDP of more than about $5,000 per annum there is a long-term tendency to growth of participation. The worldwide Gross Tertiary Enrollment Ratio (GTER) increased from 10% in 1972 to 32% in 2012, and is now rising by 1% a year. By 2012 the…

We provide a 5E structured-inquiry lesson so that students can learn more of the mathematics behind the logistic model of population biology. By using models and mathematics, students understand how population dynamics can be influenced by relatively simple changes in the environment.

This executive summary highlights research findings on outcomes in education, employment, and income in the southern United States region. Findings include: (1) As a whole, Southern schools, colleges, and universities perform better than ever, though they are in constant need of improvement to meet the demands of both democracy and a changing…

The "Next Generation Science Standards" (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the…

Ratio and proportional reasoning tasks abound that have connections to real-world situations. Examples in this article demonstrate how textbook tasks can easily be transformed into authentic real-world problems that shed light on issues of equity and fairness, such as population growth and crime rates. A few ideas are presented on how teachers can…

Despite wars, natural disasters, fears of epidemics and pandemics, and other catastrophic events that are vividly featured in media outlets, the world's population continues to rise. In fact, the world recently passed another demographic milestone: a human population of 7 billion people. The number of people on Earth has tripled since around 1930,…
