There has been a limited amount of research that has attempted to determine teaching strategies using adaptive learning systems. Most studies have attempted to measure success of the use of these technologies based on improvements in students' test scores but have lacked to provide any information regarding the pedagogy implemented while using the…

The COVID-19 pandemic forced teachers worldwide to shift to emergency remote teaching (i.e., virtual teaching). As teachers return to their classrooms for in-person teaching, there is a need to examine how remote teaching influences teachers' instruction. This study examined teachers' use of digital technologies and specific mathematics activities…

Digital technologies and the instructional contexts in which they are embedded can increase students' access to meaningful learning opportunities. Although there is a tradition of designing and integrating digital tools in secondary-grades project-based science instruction to enhance learners' access to disciplinary learning, the elementary grades…

In this article, we share design guidelines for the development and use of online, video-based "teaching playgrounds," which provide opportunities for prospective teachers to engage in professional noticing of teaching practices. Through teaching playgrounds, we provide an instantiation of the Presence+Experience framework, which…

Khan Academy (KA) is a free web-based intelligent tutor, which has been featured in countless media outlets for its potential to change mathematics instruction. The founder and executive director, Salman Khan, recommends that KA be used to personalize instruction, freeing up class time for engaging high yield activities like student discourse and…

Over the last decade there has been a rapid diffusion of cellular technology. Though cell phone use began as a business tool, it has now become part of popular culture. Because of the near ubiquitous presence of cell phone technology among teens in the United States, schools are beginning to explore the use of cell phones as a learning tool. This…

This article justifies classifying the TI-Nspire CAS Touchpad as a mobile device for grades 8-16 mathematics classrooms equipped with a Navigator system. The 2010 Horizon Report: K-12 indicates virtually every secondary school aged child has some sort of mobile device. Yet, many school policies ban the use of mobile devices, preventing students…

High school algebra and geometry teachers use graphing calculators extensively in their classes today. National and state mathematics curriculum standards recommend their use for class work, tests and assignments. Because of recent legislation, including "IDEA 2004" and "No Child Left Behind", most students with mild…
