Applying Quantitative Reasoning To Clarify Arc Measurements, David Glassmeyer, Daniel Barton
Applying Quantitative Reasoning To Clarify Arc Measurements, David Glassmeyer, Daniel Barton
Georgia Educational Researcher
The importance of reasoning quantitatively is reflected in both mathematics education research and mathematical standards for K-12 students. In this article, we detail how a quantitative reasoning framework can be used to help differentiate two quantities we have found students often struggle with: arc length and the measure of a central angle. We argue that taking the time to define all four components of a quantity can support students’ understanding of theorems involving these quantities.
Complex Adaptive Systems And Quantitative Reasoning In An Interdisciplinary Stem Mathematics Classroom, Robert L. Mayes, Kania Greer
Complex Adaptive Systems And Quantitative Reasoning In An Interdisciplinary Stem Mathematics Classroom, Robert L. Mayes, Kania Greer
Interdisciplinary STEM Teaching & Learning Conference (2012-2019)
In this presentation we will share outcomes from the Real STEM project, which provides professional development for rural teachers in the Georgia Coastal Plains supporting implementation of interdisciplinary STEM courses as well as STEM modules in mathematics and science courses. Real STEM includes a number of innovative student-active strategies for teaching including: Understanding by Design (UbD) approaches to teaching for understanding, problem-based learning (PBL), place-based education (PBE), complex adaptive systems (CAS) thinking, and quantitative reasoning (QR). QR is the mathematical underpinning of the projects. The projects are ongoing so we will report our results on impact on teacher practice and …

Quantitative reasoning is a complex concept with many definitions and a diverse account in the literature. The purpose of this article is to establish a working definition of quantitative reasoning within the context of science, construct a quantitative reasoning framework, and summarize research on key components in that framework. Context underlies all quantitative reasoning; for this review, environmental science serves as the context.In the framework, we identify four components of quantitative reasoning: the quantification act, quantitative literacy, quantitative interpretation of a model, and quantitative modeling. Within each of these components, the framework provides elements that comprise the four components. The …
