Reasoning maps: a generally applicable method for characterizing hypothesis‐testing behaviour

Abstract

This paper presents a generally applicable method for characterizing subjects’ hypothesis‐testing behaviour based on a synthesis that extends on previous work. Beginning with a transcript of subjects’ speech and videotape of their actions, a Reasoning Map is created that depicts the flow of their hypotheses, tests, predictions, results, and conclusions. The methods are described and then applied to a group of three undergraduate biology students testing hypothesis in an inquiry‐based laboratory exercise, the Red and White Yeast Lab. Analysis of hypothesis‐testing behaviour via Reasoning Maps reveals most of the features explored in previous studies in a unified context. In addition, Reasoning Maps allow analysis of higher‐order patterns in hypothesis testing that are not possible using existing methods. We have designed these methods so that they will provide a common language for analysing and understanding hypothesis testing that will allow global comparisons of behaviour.
