This study addresses the need to better describe instructional strategies used by middle grades mathematics teachers. After coding 177 videos of grades 6-8 mathematics instruction for indications of effective instructional practices, we further analyzed 8 of the highly scored videos with specific attention to teachers' implementation of strategies associated with Explicit Attention to Concepts (EAC) (Champion et al., 2020). We found that these effective teachers of mathematics tended to enact EAC by using a preferred strategy more predominantly than others, though all teachers used at least two EAC strategies during a lesson. Additionally, most participants in our study used an Initiate, Response, Evaluate (IRE) format (Mehan, 1979) when enacting EAC. We illustrate examples of their instruction with vignettes.
