This study aims to identify how mathematics teachers understand whole-class discussions and to know the influence of lesson study on the way they orchestrate these discussions. This is a qualitative study, conducted with two groups of middle school teachers. We analyze data concerning three teachers, Patrícia, Marta, and Diana, collected through…

Introduction: In today's world, which is progressively oriented towards science and technology and facing a growing demand for skilled professionals, it becomes essential to identify the factors that encourage individuals to pursue careers in STEM fields (Science, Technology, Engineering and Mathematics). Previous research has shown that…

Recognizing that a successful middle school is one where adult advocates foster and guide students' academic and personal development (Bishop & Harrison, 2021), we explore how COVID-19 acted as a catalyst for one middle school to create novel spaces that supported students' social and emotional well-being. Calling on Bhabha's (1994) and…

Curriculum materials are not a fixed object; they are an active partner in a teacher's practice. Teachers and curriculum materials interact in a participatory relationship where both the characteristics of the teacher and the characteristics of the curriculum material affect the instruction. Teachers interpret and tailor these materials to create…

This study examined if in-class, online, and hybrid (in-class and on-line) instruction provided to middle and high school students in the U.S. differed during the third school year of the COVID-19 pandemic. It also provided a description of how writing was taught to secondary students. Thirty-eight middle and high school teachers (32 female, 6…

The purpose of this study was to discover methods and practices that have led to successful collaboration between school librarians and classroom teachers. A qualitative design with a phenomenological approach was employed to discover the lived experiences of six credentialed school librarians and six classroom teachers who have successfully…

Research-practice partnerships play an important role in critically examining racial disparities in schools, as well as supporting the immediate adoption of practice improvement. This article outlines the results of a multisite case study with students, teachers, and administrators across two racially and ethnically diverse middle schools in the…

There are strong motivations to implement integrated STEAM activities that engage with key ideas in mathematics. In integrating mathematics with other STEM disciplines, however, epistemic tensions can emerge. Rather than attempting to suppress, avoid, or adjudicate these tensions, we propose a strategy of "epistemic rekeying," in which…

Units Coordination and Covariational Reasoning are powerful frameworks for modeling students' mathematics in arithmetic reasoning and construction of relationships between changing quantities, respectively. This case study of an advanced stage 2, 8th-grade algebra student, Daniel, investigated connections between his units coordination and…

Insufficient sleep and sleepiness are common in adolescence and can negatively impact school performance. The current study examined sleep duration and sleepiness in academic performance and cognitive processes in early adolescence. Middle school students (N = 288; M[subscript age] = 12.01; 54% female; 48% Black, 37% White, 10% Hispanic) wore…

Over the past decade, the arts' potential role in advancing mainstream transdisciplinary curriculum models, like STEM, has been more overtly recognized, both within arts and STEM communities. In this study, we explored STEAM curricula centered around data visualization, a transdisciplinary practice commonly utilized in design and STEM fields and…

In order to explore the effects of prosocial behavior, teacher's attitudes towards bullying, and classroom climate on peer victimization, we collected data from 1,221 students (M[subscript age] = 13.60, SD = 0.88) from 47 classrooms and their teachers from three middle schools in Beijing, China. The hierarchical linear modeling was used to examine…

Informed by multiple theoretical perspectives pertaining to academic procrastination, this investigation examined multilevel models aimed to predict homework procrastination using the data from 1,072 middle schoolers in China. Our model incorporated student gender, homework motivation, homework approach, homework behavior, and time allocated to…

When implementing digital technologies into mathematics teaching and learning situations, new representational and communication infrastructures arise that allow for new speech acts and actions. These new speech acts and actions are also referred to as 'representational expressivity'. Such expressivity arises in the intersection of…

Scholars and practitioners have called for personalized and widely accessible professional development (PD) for teachers. Yet, a long-standing tension between customizing support and increasing access to such support has hindered the scale-up of high-quality PD for individual teachers. This study addresses this challenge by developing a…
