A Laboratory Teaching Model Which Trains Students to Exercise Discretion: Evaluating Water Quality

 

Tested Studies in Laboratory Teaching, 1986, Volume 7

Abstract

Rather than give students specific prescriptive laboratory procedures, this method provides the student with a task, two or three procedural steps, and a list of resources available to accomplish the task. The method is illustrated in this chapter by an activity in which the student evaluates the quality of water from several unknown sources using abundance if indicator organisms and diversity as criteria.
