geometric analysis of suction feeding

Geometric Analysis of Suction Feeding

The universe is written in the language of mathematics◦ Galileo Galilei, 1623

Quantitative analysis of natural phenomena is at the heart of scientific inquiry

Nature provides a tangible context for mathematics instruction

Math & Nature

Context

1. The part of a text or statement that surrounds a particular word or passage and determines its meaning.

2. The circumstances in which an event occurs; a setting.

The Importance of Context

Context-Specific Learning

◦ Facilitates experiential and associative learning

Demonstration, activation, application, task-centered, and integration principles (Merrill 2002)

◦ Facilitates generalization of principles to other contexts

The Importance of Context

Geometry & Biology◦ Biological structures vary greatly in geometry and

therefore represent a platform for geometric education

◦ Geometric variability functional variability ecological variability Mechanism for illustrating the consequences of

geometry
