The inappropriate use of subsumers in biology learning

Summaries English This paper presents the results of a study of the development of pupils’ knowledge of the process of photosynthesis and the related biological processes of respiration, breathing and digestion. The information already known to primary pupils untutored in biology was assessed and the changes effected by teaching were monitored in the secondary school. The results indicate that concepts which are wrong but which are nevertheless meaningful to the learner may escape detection by the usual methods of testing and are highly resistant to replacement by correct information. The formation of wrong concepts may predate formal instruction or may arise during the course of instruction as a result of the inappropriate use of subsuming information.
