Interest in teachers' moves to classroom discourse has started to increase since how teachers respond to students' thinking influences students' learning. The purpose of this study was to investigate the moves used by one sixth grade mathematics teacher at a public middle school in Turkey to support student reasoning in mathematics instruction and…

Meaningful participation in science and engineering practices requires that students make their thinking visible to others and build on one another's ideas. But sharing ideas with others in small groups and classrooms carries social risk, particularly for students from nondominant groups and communities. In this paper, we explore how students'…

A key goal of recent reforms in science education has been to support students' collective sensemaking, in which they work together to understand a natural phenomenon. This work is often done during class discussions, but facilitating those discussions is challenging. In this study, we used a framework of three discussion types to investigate how…

Many teachers around the country are doing Number Talks in their classrooms. This powerful and accessible technique can open teachers' eyes to how their students talk about their own thinking and can help students see themselves as mathematical thinkers and describers of their own thinking. Teachers use annotations of student thinking to visually…

In this small, mixed methods pilot study twenty-three 5th graders and two 6th graders from a large, urban middle school in the Northeast United States were given Accountable Talk (AT) sentence stems to use during a series of academically productive talk (APT) in their science classrooms over a 2-week period in the Spring of 2024. The goal of the…

In the wake of the events of recent years, most school leaders and educators recognize that taking equity seriously demands new attention to the instructional experiences that occupy most of students' time in school. In what follows, we bring together key literature on ambitious teaching-learning and equitable classroom practice in an observation…

The purpose of this study is to investigate the quality of class talk during episodes corresponding to different levels of generalization. A total of 10 sessions in two classrooms in grade 7 were videotaped. A mixed approach was adopted to analyze the videotaped sessions. The findings show that triadic dialog was the dominant mode of interaction…

The paper reports qualitative findings from a study about how science teachers enacted discursive purposes and talk moves to support the students' experiments. Science teachers may have difficulties assisting students in designing and conducting valid and reliable experiments as the core epistemic practice of science teaching and learning. It is…

Dialogic talk affords students opportunities to share ideas and co-construct knowledge while developing various literacy skills such as perspective taking, text comprehension, and argumentative reasoning. In this study, we examine how seventh- and eighth-grade students in four classrooms discuss a controversial topic about changing a National…

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…

Teacher expectancy (TE) refers to the inferences that teachers make about academic achievement, and future career choice of their students, it is a teacher level variable, and it mediates the teacher-student interaction. I hypothesize that the TE impacts the distribution of learning opportunities in 8th grade mathematics classes. So, I investigate…

Statistics has been a content domain in the mathematics curriculum for decades. However, statistics is a distinct discipline from mathematics and there are important differences in how one should teach the two disciplines. In this article, the authors consider how these differences can inform an adaptation to the 5 Practices for Orchestrating…

It is still a challenge for students to engage in classroom dialogue actively and realize effective dialogue-based learning, as classroom dialogue are influenced by a multitude of factors. It is reasonable to believe that by delving into a specific variable (perceived care) to gain insights into its potential impact on dialogue engagement, which…

Participating in classroom mathematics conversations, particularly engaging with the opinions of others, can improve learners' mathematical comprehension. Teachers can use a variety of invitation and follow-up moves to encourage student engagement. The study aimed to explore teacher follow-up on learners' initial responses to teacher questions and…

In this article, the authors describe the two interpretations of mathematical expressions, as a process and as a product. They begin with an initial discussion of Tall's (2013) interpretations of expressions and connect this to state standards. Next, they describe the different interpretations of algebraic expressions based on their work with…
