Abstract Recent research suggests that many South African pupils in their final year of schooling have erroneous ideas about various aspects of respiration (Sanders and Cramer, 1992). This study investigates teachers as a possible source of pupils' errors. The views of 136 biology teachers about respiration and related concepts were elicited by means of an analysis of how teachers marked an essay containing errors commonly found among year‐12 pupils. The teachers' responses suggest that many of them might well have erroneous ideas. These are reviewed in terms of four conceptual areas related to respiration. Finally the implications for teachers are discussed, and suggestions are made about possible ways to address the problem of erroneous ideas among teachers and pupils.
