A Framework for Teachers’ Evaluation of Digital Instructional Materials: Integrating Mathematics Teaching Practices with Technology Use in K-8 Classrooms

by Amanda Thomas & Alden J. Edson
Full Article Show Abstract

The study explored the evaluation of digital instructional materials (DIMs) by K-8 teachers of mathematics, positing that a useful perspective for evaluating DIMs by K-8 teachers of mathematics is considering how technology integrates with research-based practices for teaching mathematics. This paper describes the study that drew on the documentational approach of didactics and reports on analyses of teacher-generated frameworks that encompass research-informed mathematics teaching practices combined with three levels of technology integration. Analyses revealed several themes in how technology could transform effective mathematics teaching practices: (a) from one-size fits all toward differentiating for student needs, (b) from static displays toward dynamic representations, and (c) from teacher-centered toward student-centered practices. The framework and themes offer opportunities for mathematics teacher educators to support teachers in making technology integration choices that positively impact pedagogy.

Online Mathematics Teacher Education in the US:  A Status Report

by Dinglei Huang & Azita Manouchehri
Full Article PDF Show Abstract

The advancement of online technologies in recent years has increased the number of teacher learning opportunities offered in virtual environments. The development of the online medium for educational purposes has raised challenges for organizing and conducting professional development for teachers, especially relative to the ways subject matter disciplinary knowledge may be facilitated in such a medium. Using a survey instrument, data were collected from a national sample of mathematics teacher educators related to the content of their pedagogical practices in online mathematics teacher education. Results highlighted eight dimensions associated with mathematics teacher educators’ decisions when designing and implementing online mathematics teacher professional development or academic courses. Knowledge required for mathematics teacher educators for each dimension of decisions is discussed.

Designing to Provoke Disorienting Dilemmas: Transforming Preservice Teachers’ Understanding of Function Using a Vending Machine Applet

by Allison McCulloch, Jennifer N. Lovett & Cyndi Edgington
Full Article PDF Show Abstract

The purpose of this study was to investigate a function machine in the form of a Vending Machine applet as a means to motivate preservice teachers to examine their own understanding of the function concept. The applet was designed to purposefully problematize common misconceptions associated with the algebraic nature of typical function machines. Findings indicate that the preservice teachers for which the applet provoked a dilemma elaborated on or transformed their understandings related to the definition of function.

Novice Secondary Mathematics Teachers’ Evaluation of Mathematical Cognitive Technological Tools

Full Article PDF Show Abstract

As technology becomes more prevalent in the mathematics classroom, teachers will need to be able to effectively evaluate technological tools to use with students. In this study, the authors examined secondary mathematics teachers’ evaluation of online dynamic geometry tools. The analysis focused on the teachers’ noticing of technology; specifically, what features within the tools mathematics teachers attended to, how they interpreted these features, and in what ways they responded. Findings indicated that secondary mathematics teachers attended mostly to mathematical features of the tools and considered the tools’ ability to focus on student engagement and student thinking to be very important, as well as the ease of implementation of the tool. The secondary mathematics teachers tended to begin their evaluation by determining how the tools work and attending to its appearance and then moved toward examining the mathematical features and how they related to student thinking.
