Abstract
Dynamic representational technologies (DRTs), influenced by the seminal work of James Kaput and colleagues, have been in use in mathematics classrooms for decades. In this paper, we analyze 24 classrooms in the United States where teachers support students’ conceptual learning with technologies that support explorations of dynamic connections both within and across mathematical representations. These DRTs, built in alignment with Kaput’s principles, form part of a curricular activity system that embeds a central pedagogical routine. Yet despite the use of common DRTs, lessons, and professional development, classroom teaching practices varied widely. We characterize and analyze levels of technology use, which vary from using the technology as a static resource to taking advantage of dynamism to support students’ emerging explanations of mathematical concepts. There are important implications for further research into classroom use of DRTs and, more broadly, for curriculum developers and teacher educators.

I often use computers for instructional purposes. (TPK)
-
I am often frustrated when I use technology. (TK)

-
I learn technologies easily. (TK)
-
I feel comfortable having my students use a tablet/laptop during instruction. (TPK)
-
Using technology enhances students’ learning of mathematical concepts in my classroom.(TCK)
-
Using technology increases student engagement and interest in learning mathematics. (TCK, TPACK)
-
I frequently explore new technology for instruction. (TPK)
Examples items from the Teacher Allowance for Student Struggle with Problems (TASSP) measure (Clark et al., 2014):
-
Students learn mathematics best by working to solve accessible problems that entail a solution process that has not been demonstrated to them.
-
During mathematics class, I do not necessarily answer students’ questions immediately but rather let them struggle and puzzle things out for themselves.
-
During mathematics class, discussion should focus on students’ ideas and approaches, no matter whether their answers are correct or incorrect.
-
During mathematics class, students should be asked to solve problems and complete activities by relying on their own thinking without teachers modeling an approach.
-
Students can figure out how to solve many mathematics problems without being told what to do.
