In this chapter, we explore the use of Augmented Reality (AR) and Virtual Reality (VR) in geometry courses for teachers. There is increasing use of AR and VR technologies, such as AR and VR goggles, in K-12 schools, providing new opportunities for learners to interact with geometry in three-dimensional (3D) environments. These opportunities lead…

In previous work, we described how three teachers differentially create opportunities for students to act as epistemic agents and to engage in collective knowledge-building work (Alzen et al., 2020). The descriptive nature of this previous research provided information about what variability can look like in classrooms attempting these…

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…

Family-school partnership interventions can effectively address behavioral concerns in students (Smith et al., 2020). However, little is known about factors impacting successful delivery of behavioral strategies by parents and teachers in the context of such interventions, particularly for adolescent populations. This study used a mixed methods…

Adolescents are in a dynamic period of cognitive, emotional, and behavioral development. School-based interventions that focus on social-emotional learning, including the development of self-regulation skills, have been shown to have positive impacts on students' mental health and academic achievement. In this qualitative study, we examine health…

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…

Many middle school students perform below grade-level standards in reading (National Center for Education Statistics, 2019), and recent observation studies demonstrate middle school teachers' limited use of reading comprehension practices within content area instruction (e.g., science and social studies; Greenleaf & Valencia, 2017). In this…

Response Process Validity (RPV) reflects the degree to which items are interpreted as intended by item developers. In this study, teacher responses to constructed response (CR) items to assess pedagogical content knowledge (PCK) of middle school mathematics teachers were evaluated to determine what types of teacher responses signaled weak RPV. We…

Teacher learning in asynchronous online professional development (PD) is often assessed through self-reported instruments, despite uncertainties regarding teachers' ability to accurately self-assess their learning gains in such settings. This study compared middle school mathematics teachers' self-perceived and observed learning gains in content…

Teachers' classroom management practices are an essential aspect of supporting student engagement, yet they often vary in response to changing conditions in the classroom. This study explored the variability within middle school teachers' observed practice and their students' engagement as a function of contextual factors. Observers visited…

It is essential for items in assessments of mathematics' teacher knowledge to evoke the desired response processes -- to be interpreted and responded to by teachers as intended by item developers. In this study, we sought to unpack evidence that middle school mathematics teachers were not consistently interacting as intended with constructed…

Solving mathematical problems is cognitively complex, involving strategy formulation, solution development, and the application of learned concepts. However, gaps in students' knowledge or weakly grasped concepts can lead to errors. Teachers play a crucial role in predicting and addressing these difficulties, which directly influence learning…

Understanding science allows students with and without developmental and behavioral-based (DB) disabilities to better appreciate the world around them as well as prepare them for the growing science-related job market. However, students in the United States consistently underperform on science achievement tests compared to students from other…

Extended Reality (XR) experiences for mathematics teachers can allow them to understand both pedagogy and the mathematics itself in new ways. In this study, we explore a virtual reality (VR) simulation for learning about geometric shapes where teachers could engage in joint, shared manipulation of holograms in three dimensions. We examine what…

Though emerging research supports the effectiveness of school-based coaching models utilizing motivational interviewing (MI), an examination of the specific drivers behind these effects is notably lacking in the prevention field. This study leveraged sequential analysis to examine how teachers' verbalization of change talk (i.e., language in…
