What Can We Learn From The Different Understandings Of Mathematical Literacy?, Svein Arne Sikko
Numeracy
Mathematical literacy, quantitative literacy, numeracy, matheracy, disciplinary literacy, and content-area literacy are among a plethora of terms used to link mathematics and literacy. In addition to this abundance of terms, the content of the terms is not precise, and in some cases the terms are used interchangeably. I delve into this landscape and dissect the meaning of each of them. From such an analysis of mathematical literacy, numeracy, and quantitative literacy, we learn about the importance of quantitative practices and elementary mathematics in society, including both how mathematics is necessary for everyday life but also how it can be used …

Let All Voices Be Heard: Creating An Engaging And Inclusive Asynchronous Qr Classroom, Ruby A. Daniels, Kathryn Appenzeller Knowles
Numeracy
With the shift to remote teaching, many instructors used Zoom for synchronous work. However, this presented issues (fatigue, turning cameras off, inequitable technical hurdles) that motivated quantitative reasoning (QR) instructors to look for asynchronous alternatives. A common technique has been text-based online discussions, which can be difficult for students to find engaging. This mixed method study (N = 41) describes an inclusive video alternative, specifically for teaching QR and quantitative fluency skills, which was piloted in two asynchronous sections and one hybrid section of the same course. Students posted their video responses, watched their classmates’ videos, and wrote short …

Using Covid-19 Vaccine Efficacy Data To Teach One-Sample Hypothesis Testing, Frank Wang
Numeracy
In late November 2020, there was a flurry of media coverage of two companies’ claims of 95% efficacy rates of newly developed COVID-19 vaccines, but information about the confidence interval was not reported. This paper presents a way of teaching the concept of hypothesis testing and the construction of confidence intervals using numbers announced by the drug makers Pfizer and Moderna publicized by the media. Instead of a two-sample test or more complicated statistical models, we use the elementary one-proportion z-test to analyze the data. The method is designed to be accessible for students who have only taken a …
