As states and districts expand their goals for equitable mathematics instruction to focus on cultural responsiveness and rigor, it is critical to understand how teachers integrate multiple teaching approaches. Drawing on survey data from a larger study of professional learning, we use mixture modeling to identify seven unique ways that middle school mathematics teachers integrate ambitious, traditional, and culturally responsive (CR) mathematics instruction. The resulting typology is driven almost exclusively by variation in CR teaching. About half of teachers reported rarely engaging in CR teaching. Teachers who emphasized CR teaching tended to be teachers of color and have high CR teaching self-efficacy. Findings suggest that tailoring teacher development to how teachers blend multiple approaches may best support equitable mathematics instruction.

Background:
For nearly three decades, policy-makers and researchers in the United States have promoted more intellectually rigorous standards for mathematics teaching and learning. Yet, to date, we have limited descriptive evidence on the extent to which reform-oriented instruction has been enacted at scale.

Purpose:
The purpose of the study is to examine the prevalence of reform-aligned mathematics instructional practices in five U.S. school districts. We also seek to describe the range of instruction students experience by presenting case studies of teachers at high, medium and low levels of reform alignment.

Participants:
We draw on 1,735 video-recorded lessons from 329 elementary teachers in these five U.S. urban districts.

Research Design:
We present descriptive analyses of lesson scores on a mathematics-focused classroom observation instrument. We also draw upon interviews with district personnel, rater-written lesson summaries, and lesson video in order to develop case studies of instructional practice.

Findings:
We find that teachers in our sample do use reform-aligned instructional practices, but that they do so within the confines of traditional lesson formats. We also find that the implementation of these instructional practices varies in quality. Furthermore, the prevalence and strength of these practices corresponds to the coherence of district efforts at instructional reform.

Conclusions:
Our findings suggest that unlike other studies in which reform-oriented instruction rarely occurred (e.g. Kane & Staiger, 2012), reform practices do appear to some degree in study classrooms. In addition, our analyses suggest that implementation of these reform practices corresponds to the strength and coherence of district efforts to change instruction.
