This article presents a microanalysis of how a group of primary school teachers deals with research evidence in their work. Based on analysis of a group of Norwegian teachers' interactions over issues of educational research and research-based knowledge, we find that teachers' representations of educational research particularly center on the following issues: educational research being perceived as circular, "polyphonic," and a matter of accommodation to their experience-based knowledge. These metaphors also shed light upon the dilemmas that arise when research evidence meets teachers' more contextual knowledge. We conclude that teachers' practice-based evidence may take new forms with an increased policy focus on research-based evidence, as well as bringing forth challenges for teacher work and professionalism.
