In this article we advance characterizations of and supports for elementary students'
progress in generalizing and representing functional relationships as part of a …

We investigated covariational reasoning among 487 secondary mathematics teachers in the
United States and South Korea. We presented an animation showing values of two varying …

This paper articulates a stance on the study of students' meaningful mathematics
understanding with multiple representations. We integrate Thompson's theory of quantitative …

The purpose of this study was to develop the tasks to measure functional thinking and to
verify their suitability by applying them to third-grade students. For this purpose, various …

This research addresses the issue of how to support students' representational fluency—the
ability to create, move within, translate across, and derive meaning from external …

This study characterizes children's understandings of quadratic function from a variation
perspective in the context of a quantitatively rich instructional setting. We studied middle …

Understanding and reasoning with functions permeates mathematics education standards at
all grade levels. Research shows students take multiple approaches to building functions …
