Dunkerton (1981) has argued that one‐zero sampling methods are useless for quantitative observational research in classrooms. His conclusions rest on a confusion of reliability and validity, on unjustified confidence in the importance of absolute values of frequency and duration of behaviours, and a misunderstanding of the nature ofscientific measurement. Observational procedures do need to be clearly specified, butone‐zero sampling provides a useful choice of method in many circumstances.
