Meet Me at the Crossroads: Over-Fishing to Meet the Standards
Donovan, John E., II
AMATYC Review, v30 n1 p36-46 Fall 2008
To achieve the vision of mathematics set forth in "Crossroads" ("AMATYC," 1995), students must experience mathematics as a sensemaking endeavor that informs their world. Embedding the study of mathematics into the real world is a challenge, particularly because it was not the way that many of us learned mathematics in the first place. This article is about one such example, the effects of fishing on fish populations, but the method of analysis used is widely applicable. The fishing model developed is based on intuitions about how populations change over time. Traditionally such examples are reserved for the study of calculus and differential equations, but qualitative methods of analysis make them accessible to students in precalculus. This example, and others like it, should not be considered add-ons to an already over-burdened curriculum. Rather, such problems provide launching points for students to develop deep understandings of mathematics through investigation of things that are real.
