Using Original Sources to Teach the Logistic Equation (UMAP)

This module uses original data, diagrams, and texts from three original sources to develop the logistic model of growth in natural systems with limited resources. The logistic differential equation and the familiar S-shaped logistic curve have applications in solving problems in ecology, biology, chemistry, and economics. The module illustrates with concrete examples how mathematics develops, and it provides insights into the assumptions that drive the modeling process.
