Interrogating an implementation filter: what constraints changes in teacher practice in response to professional development

Abstract

ABSTRACT It is well known that teacher professional development may not result in meaningful change to classroom instruction. A recent theoretical model by McChesney and Aldridge (2021) posited that this phenomenon may be explained on account of ‘implementation barriers’ to professional development delivery. The present study thus investigated the nature, structure, and distribution of such barriers to the impact of teacher professional development on classroom practice. Using survey data collected from three Illinois school districts (N = 274), we identified six distinct but non-orthogonal barriers (e.g. school culture, relevance, teacher resistance) and found that the most commonly perceived specific implementation barriers were time constraints and pressures, other curricular mandates or demands, and stress or burnout. Repeated-measures analysis of variance also showed some differences in the profiles of the six barriers across the school districts.
