Abstract
There is now a large body of research which examines students’ misconceptions in a variety of science subject areas. A problem exists, however, in applying the findings of this research to the classroom. One means of improving the application of misconceptions research is by the use of diagnostic tests which incorporate the findings of this research. A methodology for developing these diagnostic tests and the use of two such tests ‐‐ in chemistry (covalent bonding and structure) and in biology (photosynthesis and respiration in plants)‐are described. Analysis of the results of the tests given to class groups illustrate the ease of identification of misconceptions which can be subsequently addressed by the teacher.
