The complexity of chemistry has implications for the teaching of chemistry today. That chemistry is a very complex subject is shown from the research on problem solving and misconceptions that has dominated the field during the past 15 years. As Johnstone indicated, matter can be represented on the macroscopic, particulate, and symbolic levels. Students frequently do not relate these three levels, and hence have difficulty in making sense of laboratory experiments. In addition, chemistry instruction that uses unfamiliar materials, uses language that is defined differently in science than in everyday situations, and is structured according to the structure of the discipline may make learning difficult. These impediments to learning can be explained using the information processing model. Students do not integrate the threefold representation of matter in their long-term memory. Providing links between the various representations can be enhanced using the social constructivist model of learning. When students are presented with conflict situations and interact with each other and their instructor, they reflect on their knowledge and construct meaning. New programs, particularly those supported with NSF funding, that are based on making chemistry relevant through problem solving and collaborative learning hold promise for reforming chemistry education.

Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
