Ear to the Ground features voices from several corners of the mathematics education world.
Ways to Help Students Become Powerful Mathematical Thinkers
Alan H. Schoenfeld
The Hidden Beauty of Complex Numbers
Juan Carlos Ponce Campuzano
Graphing Technology Helps Narrow the Digital Divide
Maria de Hoyos
To ensure that technology use benefits all students, it must be accessible with respect to cost and ease of use. Moreover, technology needs to be integrated by considering it from the perspective of the curriculum.
Positioning Students to Explore Math with Technology
Allison W. McCulloch, Jennifer N. Lovett, Lara K. Dick, and Charity Cayton
The authors discuss digital equity from the perspective of using math action technologies to position all students as mathematics explorers.

Practices for Mathematics and Science Integration
Zandra de Araujo, Deborah Hanuscin, and Samuel Otten
In this paper we discuss different ways teachers can integrate science and mathematics into their curriculum. In particular, we focus on science and mathematics integration via the disciplinary practices.
Sorting Out Definitions
Erin E. Baldinger, Matthew P. Campbell, and Foster Graif
Students need opportunities to construct definitions in mathematics. We describe a sorting activity that can help students construct and refine definitions through discussion and argumentation. We include examples from our own work of planning and implementing this sorting activity to support constructing a definition of linear function.
Triangle Center Technology
The paper discusses technology that can help students master four triangle centers -- circumcenter, incenter, orthocenter, and centroid. The technologies are a collection of web-based apps and dynamic geometry software. Through use of these technologies, multiple examples can be considered, which can lead students to generalizations about triangle centers.
