McCormick, Bonnie – American Biology Teacher, 2009
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…

Bell, ClareValerie; Odom, ArthurLouis – Science Activities: Classroom Projects and Curriculum Ideas, 2013
In three semiguided inquiry lessons on population biology, students use models and simulations to examine population trends and make projections. They are guided to create and evaluate data and to use algebraic and geometric representations to examine biotic and logistic growth models as part of examining human population growth. As they recognize…

Baumgartner, Erin; Biga, Lindsay; Bledsoe, Karen; Dawson, James; Grammer, Julie; Howard, Ava; Snyder, Jeffrey – American Biology Teacher, 2015
Quantitative literacy is essential to biological literacy (and is one of the core concepts in "Vision and Change in Undergraduate Biology Education: A Call to Action"; AAAS 2009). Building quantitative literacy is a challenging endeavor for biology instructors. Integrating mathematical skills into biological investigations can help build…

Parrado, Emilio A.; Kandel, William A. – Social Forces, 2010
We analyze the relationship between Hispanic population growth and changes in U.S. rural income inequality from 1990 through 2000. Applying comparative approaches used for urban areas we disentangle Hispanic population growth's contribution to inequality by comparing and statistically modeling changes in the family income Gini coefficient across…

Frye, Joanna R.; Fulton, Amy P. – New Directions for Higher Education, 2020
This chapter presents a descriptive analysis of the growth of managerial and professional staff from Fall 1993 to Fall 2011 across institution types and sectors, and a detailed snapshot of the demographic composition of these staff in Fall 2016. Our results indicate tremendous growth in the population of non-faculty staff over time, and reveal key…

Sáenz, Rogelio – Journal of Hispanic Higher Education, 2020
Demographic shifts have transformed the racial and ethnic composition of the U.S. undergraduate population. Data from the American Community Survey are used to analyze Latino undergraduate enrollment as well as factors that contribute to the matriculation of undocumented Latino young adults. The article concludes with an overview of the…

Winkel, Brian J. – PRIMUS, 2011
We estimate the parameters present in several differential equation models of population growth, specifically logistic growth models and two-species competition models. We discuss student-evolved strategies and offer "Mathematica" code for a gradient search approach. We use historical (1930s) data from microbial studies of the Russian biologist,…

Niedomysl, Thomas; Amcoff, Jan – Rural Sociology, 2011
Rural depopulation is a concern in many countries, and various policy initiatives have been taken to combat such trends. This article examines whether hidden potential for rural population growth can be found in Sweden. If such potential exists, it implies that the development prospects for many rural areas are not as unpromising as they may seem…

Wollebaek, Dag – Rural Sociology, 2010
This article uses unique community-level data aggregated from censuses of associations to analyze growth and volatility in rural populations of grassroots associations. A qualitative comparative analysis (QCA) shows that the two main paths to growth were (1) centralization in polycephalous (multicentered) municipalities and (2) population growth…

After the governments of China and India, the Catholic Church is probably the third largest provider of K12 education in the world. How has growth in enrollment in K12 Catholic schools varied across countries over the last two decades? Which countries have accounted for most of the growth at the regional and global level? What has been the role of…

The 1,000-student Allegheny Valley district in Pennsylvania boasts generations of alumni and a community so involved with the schools that high school graduation becomes an open celebration in downtown Springdale Borough. Yet the district hasn't asked for a tax increase in three years, and it is pushing out a message to older residents about…

Hipkins, Rosemary; Cowie, Bronwen – Teachers and Curriculum, 2016
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…

Ra, Sungsup; Ahmed, Mahfuzuddin; Teng, Paul S. – International Journal of Training Research, 2019
Under current population growth and demographic trends -- with food demand projected to increase by 60%-70% by 2050 -- another quantum leap in food production and disruptive change in agricultural and food systems are needed in Asia. Certainly, the Green Revolution and other technological advances enormously improved agricultural productivity on…
