Teachers' beliefs, professional development, access to hardware/software, and instructional contexts all influence teachers' use of technology (Ertmer et al., 2012; González-Carriedo & Esprívalo Harrell, 2018; Ottenbreit-Leftwich et al., 2010). The first three factors have been studied extensively, but additional research on the instructional contexts of teachers, especially those working in less common settings, may enhance our knowledge of how technology shapes teachers' instruction and, subsequently, student learning. This case study highlights three teachers' beliefs and practices of incorporating technology to enhance mathematics learning and mathematical discourse in public dual-language elementary schools. Through interviews, video-recorded lessons, and workshop discussions, researchers examined why and how teachers leveraged technology to enhance mathematics learning in a bilingual program. The analysis indicates that teachers' reasoning and technology use sought to increase opportunities for discourse, a significant component of the mathematical practices (National Governors Association Center for Best Practices, 2010), strengthening their bilingual students' understanding and application of mathematical concepts, processes, and proficiencies.
