We investigated how the time elementary preservice teachers (PSTs) spent studying certain mathematics topics during teacher education coursework was related to performance on teaching-related tasks administered after graduation. In two studies, participants completed tasks assessing their specialized content knowledge (SCK) for teaching 12…

Empirical evidence exists that enhancing students' language can promote the mathematics learning of multilingual students at risk, whereas other target groups (e.g., monolingual students, successful students, both with diverse academic language proficiency) have hardly been considered. This cluster-randomized controlled trial (N = 589)…

This article contributes to the larger narrative around what makes a mathematics professional development (PD) successful and in what ways. We share a research-based PD model that was implemented in elementary schools in an urban school district for 3 years. The model uses a pseudo lesson study approach and emphasizes standards-based instruction.…

Despite progress toward gender equity, troubling disparities in mathematical problem-solving performance and related outcomes persist. To investigate why, we build on recurrent findings in previous studies to introduce a new construct, "bold problem solving," which involves approaching mathematics problems in inventive ways. We introduce…

Recent international studies have found that teachers' attitudes, biased against historically marginalized groups, predict lower student achievement in mathematics (e.g., van den Bergh et al., 2010). It is not clear, however, if or how teachers' racial attitudes affect their evaluation of students' mathematical thinking to produce these effects.…

The field of mathematics teacher education has been moving collectively toward a common goal of preparing prospective mathematics teachers to teach with technology. In this article, we present findings from a national survey of accredited university secondary mathematics teacher education programs. The purpose of the study is to describe the…

Even when parents have the time required to support their children's education, they can increase their children's anxiety about school when they try to help, especially if they are not confident in their own abilities. This study measures the effects of having parents complete nonacademic schoolwork with their teenage children. Half of the 422…

Supporting students in making mathematical arguments is an important part of discourse practices in mathematics classrooms. Differences in teachers' support for collective argumentation have been observed and documented, and the importance of the teacher's role in supporting collective argumentation is well established. This article seeks to…

Coaching is a popular, yet costly, professional development structure. Therefore, understanding the learning opportunities coaching provides is essential. Following a framework by Campbell and Griffin (2017), we explore five elementary school teachers' learning opportunities during 15 meetings and 23 lessons with two instructional coaches in two…

Some people pursuing a doctorate in mathematics education are interested in specializing in a specific area within mathematics education. In addition, people considering postdoctoral appointments often choose institutions that have niches or specializations aligned with their long-term career goals. These specialty areas are typically the result…

The purpose of this commentary is to acknowledge, illuminate, and counter the noticeable silences in the investigations of mathematics education researchers who conduct equity research with Black communities and other marginalized groups. For far too long, these communities have experienced a lengthy and complicated history of structural barriers;…

In this article, we use a two-dimensional assessment to examine the experimental impacts of a mathematics learning trajectory-oriented formative assessment program on student strategies for problems involving multiplication and division. Working from the theory that the development of students' multiplicative reasoning involves improvements in…

This article investigates the interplay of time words with how children position hands on an analog clock. Using a mathematics discourse framework (Sfard, 2008), we analyzed how students interpreted precise (e.g., 2:30) and relative (e.g., half past 11) times, finding that particular words are dynamically interwoven with activity. Interviews with…

This article explores secondary teachers' opportunities to learn from an innovative real analysis course, as reflected in their actual classroom teaching. The course used cases of teaching as a site for applying mathematics and developing pedagogical mathematical practices. This article explores particular teaching moments in (N = 6) secondary…

We use a narrative framework to investigate how mathematics textbook lessons can promote sustained student inquiry. Our analysis of four high school textbook lessons on the SSA congruence property, three of which contain explorations, reveals how explorations can promote problem-solving perseverance by inspiring readers to raise mathematical…
