A recent national study of the influence of openness of school buildings upon teaching practices and pupil outcomes has found that schools of open area design were associated with lower scores on tests of basic skills. Several possible explanations for the association are suggested in terms of the history of the open planning innovation and observed patterns of usage of school buildings. An interaction was found between school design and school social status on a measure of pupil self-esteem. No association was found between measures of openness of teaching practices and any of the pupil outcomes. Some conceptual problems are examined, especially relating to the definition of “openness” and the importance of values in the application of research findings to educational issues.
