The concept of population growth patterns is a key component of understanding evolution by natural selection and population dynamics in ecosystems. The National Science Education Standards (NSES) include standards related to population growth in sections on biological evolution, interdependence of organisms, and science in personal and social…

Schools and districts are inundated with data from a variety of sources. As a result, using data to guide instructional planning can be daunting for teachers and schools. While schools and districts are dealing with shrinking budgets and growing demands for high student achievement, an investment in school-based coaching can provide exponential…

Logistic growth displays an interesting pattern: It starts fast, exhibiting the rapid growth characteristic of exponential models. As time passes, it slows in response to constraints such as limited resources or reallocation of energy. The growth continues to slow until it reaches a limit, called capacity. When the growth describes a population,…

Intended for nonspecialists, discusses various aspects of energy in historical terms. Areas addressed include brevity of the cheap energy era, exponential growth, and ideology/controversey (suggesting relationships between power plants and economic power). Examines general literature providing a framework for qualitative thinking about energy and…

An activity in which students obtain a growth curve for algae, identify the exponential and linear growth phases, and calculate the parameters which characterize both phases is described. The procedure, a list of required materials, experimental conditions, analytical technique, and a discussion of the interpretations of individual results are…

This analysis looked at higher education facilities management that, despite exponential growth in responsibilities since the 1960s, has seen reduced resources for operations and maintenance. By extrapolating 1988 data from the National Center for Education Statistics, the review estimated that there are now 3.4 billion square feet of higher…
