This editorial explores the transformative potential of technology in advancing equitable teaching and learning in mathematics education. The COVID-19 pandemic has underscored the need for innovative approaches to education, particularly in leveraging technology to create more inclusive and effective learning environments. This special issue focuses on how emerging technologies can deepen students' mathematical proficiencies, shape students' identities, and promote equitable teaching practices. The EqT-tech framework is introduced, highlighting six key dimensions that enhance equitable mathematics education through technology: inquiry-based learning, mathematical identity and agency, formative assessment, collaborative learning, amplification of cognitive processes, and insights into social justice issues. Through a review of seven manuscripts, three recurring themes are identified: the use of technology to develop students' mathematical identity and agency, the role of collaborative platforms in enhancing collective learning, and the expanding nature of emergent technology to increase mathematical rigor as well as awareness for teaching mathematics for social justice exploring inequities within our communities. These studies imply an emphasis on the importance of task design and teacher knowledge in implementing equitable teaching practices, suggesting that technology, when used thoughtfully, can significantly advance equity in mathematics education.

The positive impact on student learning and continued support of mathematical action technology (MAT) in classrooms deems a need to better understand what teaching practices maximize the affordances of MATs. The purpose of this study was to better understand the technology-centered teacher moves that allow students the opportunity to be positioned as mathematical explorers and sustain mathematical authority during a MAT task. In this case study of a MAT task designed to leverage the power of sliders in Desmos to explore key characteristics of the sine function, participants were two ninth-grade students (age 14), who engaged with a task-based interview. By coding the transcript of the task-based interview, the findings identified and described the teacher's actions with the technology that resulted in meaningful mathematical activity for the two students. Along with teacher actions with the technology, evidence showed the importance of the design of the MAT task and the ability of students to troubleshoot the technology. Ultimately, we identified important considerations for teaching mathematics with technology as well as several technology-centered teaching moves, leaving room for the students to perform as mathematical explorers. Applying these research methods for future cases could help generalize these technology-centered teaching strategies that position students as mathematical explorers, thus strengthening students' mathematics identities.

This article explores how the use of technology along with carefully designed tasks can advance equity in the teaching of mathematics. Focusing on one of the dimensions of the EQTTech lesson analysis tool, this study examines how the use of technology can support the development of authority, identity, and agency in minoritized high school youth. A lesson on central tendency was designed and enacted in two 9th grade classrooms using GeoGebra and Padlet technologies. Student work and video recordings of the lesson were analyzed for student expressions of authority, identity and agency. These key constructs were intertwined in practice, and appear to be supported by the pairing of carefully selected tasks with technology chosen for its potential to advance equity.

Technology has potential to support mathematics teaching and learning when technology is used in specific ways. This study examines how the use of mathematics learning technologies (MLTs) promotes students' Access, Power, and Achievement, as defined by Gutiérrez' (2009, 2012) equity-based framework. The article includes two cases that were collected during the authors' time engaging with students in mathematics classrooms through work in elementary school classrooms. The inductive qualitative analysis of data conducted during teaching episodes concluded that teachers' launch of the activities that used MLTs and their support during MLT use influenced students' Access, Power, and Achievement. Specifically, the more support that a teacher provided with direct telling was associated with decreases in Access and Power. There was also evidence of student engagement and Achievement based on teachers' actions during MLT activities. The article concludes with implications to support teachers' enactment of specific pedagogies during the use of MLTs in order to promote Access, Power, and Achievement.

Learning mathematics in a student-centered, problem-based classroom requires students to develop mathematical understanding and reasoning collaboratively with others. Despite its critical role in students' collaborative learning in groups and classrooms, evidence of student thinking has rarely been perceived and utilized as a resource for planning and teaching. This is in part because teachers have limited access to student work in paper-and-pencil classrooms. As an alternative approach to making student thinking visible and accessible, a digital collaborative platform embedded with a problem-based middle school mathematics curriculum is developed through an ongoing design-based research project (Edson & Phillips, 2021). Drawing from a subset of data collected for the larger research project, we investigated how students generated mathematical inscriptions during small group work, and how teachers used evidence of students' solution strategies inscribed on student digital workspaces. Findings show that digital flexibility and mobility allowed students to easily explore different strategies and focus on developing mathematical big ideas, and teachers to foreground student thinking when facilitating whole-class discussions and planning for the next lesson. This study provides insights into understanding mathematics teachers' interactions with digital curriculum resources in the pursuit of students' meaningful engagement in making sense of mathematical ideas.

The goal of this study is to explore productive ways to engage students in groupwork using dynamic geometry tasks in online synchronous classroom environments. In particular, we aim to understand the social, mathematical, and technological aspects of student collaboration in virtual spaces. We analyzed how three online groups of students collaboratively worked on dynamic geometry tasks of exploring interactive kaleidoscope applets in Desmos and producing visual representations and written descriptions of geometric transformations used in the applets. The students shared their screens in Zoom as they shared their findings and discussed how to draw and write to represent the kaleidoscopes. We identified three emerging practices of the students collaboratively working on dynamic geometry tasks in online synchronous environments: (a) drawing in response, (b) co-construction, and (c) writing in real time. The emergent practices captured how students socially interacted with others, engaged in mathematical processes, and utilized technology tools. We also discuss inequity in students' participation in collaborative practices in an online environment and possible ways to ensure equitable learning opportunities for online students.

New technological advancements that are available in price and usability for K-12 classrooms result in new content areas to be explored and advancement of previous content area struggles. Visualizations of two-dimensional (2D) representations of three-dimensional (3D) figures and the actual 3D figure is a struggle not only limited to mathematics teaching and learning. However, if this struggle can be rectified and potentially improved through mathematics teaching and learning, the broader impacts of this extends beyond classroom mathematics. New 3D modeling software and 3D printers allow users to easily create and share models or download 3D models from online resources and print them to manipulate in their hand. There is plenty of literature now on classroom use of 3D modeling and printing. This article serves to build onto Ball and Stacey's (2005) suggestions for judicious use of calculators and computer software to address the judicious use of 3D modeling and printing technology for teaching mathematics for student learning. We discuss the following teaching strategies: promote careful decision making about 3D modeling and/or printing use, integrate 3D modeling and or printing into the curriculum, tactically restrict use of 3D modeling and or printing, and promote habits of spatial visualization.

In this paper, we describe a framework developed by synthesizing and combining scholarship from the fields of equity in mathematics education and effective integration of technology in the classroom. This framework allows researchers, educators, and teachers to examine the potential of technology-enhanced mathematics lessons to advance equity along six identified dimensions. We share a case study of a research lesson that applied this framework and implemented technology as an equity lever by allowing students to explore social justice issues using a suite of technology tools. Implications for mathematics teacher educators and researchers are discussed as ways the framework can be used to promote the equitable integration of technology.
