This qualitative study explored the reactions of practicing teachers when presented with an "encounter" experience that challenged them to examine their own bias in an on-line graduate course. In this case, the encounter experience was completing two Implicit Association Tests--one on race and one on skin tone. The researchers examined the discussion board entries of 302 early childhood and elementary teachers enrolled in the course and found that teacher reactions generally typified one of five categories: (a) disregard for the results, (b) disbelief in the results, (c) acceptance of the results, (d) discomfort with the results, and, finally, (e) distress with the results. The results are discussed in the context of helping teachers become aware of the potential impact of bias on the teaching and learning process. Pedagogical strategies to mediate the typology of reactions to the suggestion of personal bias are highlighted.
