COX, D.E.*; BERTRAM, J.E.A.: Hypothesis testing as a lab exercise: a simple walking study
This paper describes a laboratory exercise designed to provide students with experience testing a hypothesis by systematically isolating and controlling determinant variables. The study involves the analysis of walking and is performed by the students on a subject from within their lab group. The study requires use of a motorized treadmill, tape measure, stop watch, personal cassette player and calculator. The exercise is designed to include factors that the students are familiar with, so they can focus on the isolation of parameters without being confused about the process they are investigating. However, the exercise will not turn out as they anticipate, meaning they will be forced to re-evaluate the assumptions that formed the basis of their original hypothesis. This exercise is designed for a college level course in exercise science, physiology or biology, but could easily be managed by a high school honors class with appropriate guidance.
