The purpose of this self-study was to examine the effects of concentrated interaction with anti-bias/anti-racist media on a Montessori guide’s practice. It was conducted over a total of six weeks. The intervention included a pre- and post- survey of understanding, nightly media interactions, daily reflection journaling, daily tallies of anti-bias/anti-racist thoughts during the school day, and a daily confidence scale to measure the participant’s confidence to integrate anti-bias/anti-racist concepts into her teaching practice. The study was completed at a private Montessori school in a medium-sized midwestern town, with an early childhood classroom of fifteen three- to five-year-old students of diverse backgrounds. The findings indicate a slight increase in confidence and efficacy for the participant in discussing anti-bias/anti-racist concepts with students, families and colleagues. The findings also point to the strong need for working with other educators and Montessorians for further integrating anti-bias/anti-racist concepts into classroom practice.
