Proficiency in mathematics is fundamental for academic success and is linked to numerous skills that are essential for success in the real-world. Despite its importance, many students struggle with math, leading to nationwide declines in math proficiency. This decline highlights the need for effective interventions that are accessible, able to be…

This comparative, multiple-case qualitative study aimed to learn more about how students learn with and behave during mathematics instructional videos. While some researchers suggest that learning and teaching mathematics online is more complex than other disciplines, others believe that learning in the video learning environment can be effective…

This qualitative, multiple case study provided comprehensive descriptions of the conceptual difficulties and learning experiences of in-service teachers as they improved their ability to effectively model fraction division with pictorial diagrams. Video data were collected on eight teachers as they individually progressed through a professional…

The rise of virtual learning established e-learning as an emerging education delivery method (Jones et al., 2022). One of the barriers to virtual education was the lack of insight into the quality of students' online learning experience. For instance, without an active instructor to clarify the course content, virtual learners viewed instructional…

Facilitators of teacher professional development (PD) play an integral role in teacher learning. Facilitators often both plan and implement PD and it is important that they can make these experiences meaningful learning opportunities for teachers. Researchers have only recently delved more deeply into understanding the knowledge and skills…

Video Modeling (VM) is one of the most widely used approaches by researchers to improve many skills, such as academic skills in students with Learning Disabilities (LD; Boon et al., 2020). As the incidence rate of individuals with LD in Saudi Arabia increase (Almedlij & Rubinstein-Avila, 2018), the need for evidence-based math interventions…

Teachers' attitudes and intentions play an integral role in the integration of technology into their lesson designs for mathematics. All K-8 students at the research site are now one to one with a device, either a tablet or laptop, depending on their grade level. It is up to teachers to determine how and when to integrate technology into their…

From a teacher's perspective, teacher learning happens through a complex web of learning experiences. However, research on teacher professional development (PD) typically focuses on the direct influence of single activities or programs. PD researchers less often acknowledge the interactive impacts on teacher learning of the multiple experiences…

To reduce inequities in the mathematics classroom, teachers must have the skill to Notice-for-Equity, a skill that can be learned and fine-tuned over time but must be practiced. The purpose of this study was to explore what preservice secondary schoolteachers notice when viewing a small-group interaction in mathematics and specifically identify…

The dominant image of mathematics as an abstract, universal, disinterested, and pure body of knowledge both misrepresents disciplinary practice and alienates many students. Undergraduate proof-based courses such as real analysis, which are supposed to introduce students to contemporary academic mathematics, often contribute to such idealized…

This study aims to explore the validity of measuring joint attention through gaze coordination in computer-supported collaborative learning (CSCL) research. Gaze coordination, aligning visual attention in social contexts, aids comprehension and communication. Many CSCL researchers use gaze coordination to gauge joint attention quantitatively.…

This study investigated how problem-solving videos can be used in video-mediated professional learning to support secondary preservice mathematics teachers (PMTs) in developing teacher knowledge for noticing student thinking in the context of the derivative concept in calculus. A model of the trajectory of PMTs' noticing was constructed as six…

The purpose of this case study was to explore the nature of instructors' gestures as they teach Euclidean transformations in a synchronous online setting, and to investigate how, if at all, the synchronous online setting impacted the instructors' intentionality and usage of gestures. The participants in this case study were two collegiate…

In 2019, RAND Corporation asked teachers which digital programs they used. This dissertation study expanded on this research by exploring the features contained in these programs. The purpose of this study was to investigate the relationships between teachers' access to features and school, teacher, and feature characteristics. This study had two…

During the COVID-19 pandemic, schools in the United States and across the world were forced into rethinking their teaching approaches for the 2020-2021 school year. In the US, the hyflex model was adopted by many schools to serve the needs of both students in person and online simultaneously. Within this new challenge is the ongoing issue of lack…
