What the World Chemical Community Thinks about the Concept of Physical and Chemical Change?
Palmer, W. P.
Online Submission, Paper presented at the Annual Meeting of the Australasian Science Education Research Association (ASERA) (Canberra, Australia, Jul 11-14, 1996)
The concept of physical and chemical change is far from being the clearest and most self-explanatory concept in the world. If a number of chemists are asked to define physical and chemical change, there may well appear to be a fair degree of uniformity in their answers, until a few examples are suggested. When chemists are asked to place a variety of changes into the category of physical or chemical change, then differences inevitably arise. It is not difficult to demonstrate this by viewing school textbooks and articles about the topic. In spite of this, physical and chemical change is still taught in most in most secondary school courses. The problem arises from the definition and the historical layers of meaning that have grown around the concept, almost by accretion, without teachers being aware of their significance. The purpose of this paper is to describe the answers given by experienced educators to a questionnaire, which attempted to find out what the views of science educators/chemists worldwide about physical and chemical change now are. Four appendixes present: (1) List of Respondents; (2) List of Questionnaires Returned; (3) Physical and Chemical Change: An Information Sheet; and (4) Full Questionnaire: Interview Protocol or Basis for Written Response.
