Abstract
Phenomenography is the empirical study of learners' qualitatively different perceptions and understandings of phenomena in the world around them. The major premise of phenomenography is that there are limited number of such understandings of a particular phenomenon observed under the same conditions, for example, in a teaching situation. The work of Ebenezer and Fraser (Sci. Educ. 2001, 85, 509-535) described here is an example of the use of phenomenographic research in categorizing concepts of the factors involved in the dissolution of ionic compounds held by students entering a first-year chemical engineering course at a university in South Africa. The purpose of the study was to provide information that could be used to design instruction to assist their students toward common, consistent understanding of energy in dissolution processes.
