Surveying The Landscape Of Numbers In U.S. News, John Voiklis, Jena Barchas-Lichtenstein, Bennett Attaway, Uduak G. Thomas, Shivani Ishwar, Patti Parson, Laura Santhanam, Isabella Isaacs-Thomas

Numeracy

The news arguably serves to inform the quantitative reasoning (QR) of news audiences. Before one can contemplate how well the news serves this function, we first need to determine how much QR typical news stories require from readers. This paper assesses the amount of quantitative content present in a wide array of media sources, and the types of QR required for audiences to make sense of the information presented. We build a corpus of 230 US news reports across four topic areas (health, science, economy, and politics) in February 2020. After classifying reports for QR required at both the conceptual …

Briggs, William. 2017. How America Got Its Guns: A History of the Gun Violence Crisis; (Albuquerque, University of New Mexico Press). 352 pp. Paperback: ISBN 978-0-8263-5813-4. E-book ISBN 978-0-8263-5814-1.

Quantitative literacy and statistics are just two of many disciplines required to understand the problem of gun violence in America. However, it’s also useful to appreciate their limitations in an issue that is so complex.

Lessons From The Pandemic, Nathan D. Grawe

Numeracy

The COVID-19 pandemic highlights the importance of quantitative literacy--for policy makers and the public at large. While all aspects of numeracy have been shown relevant to the past year, our need for broader statistical literacy appear particularly pressing. Pandemic experiences may motivate greater interest in developing numeracy skills.

Confidence Intervals Of Covid-19 Vaccine Efficacy Rates, Frank Wang

Numeracy

This tutorial uses publicly available data from drug makers and the Food and Drug Administration to guide learners to estimate the confidence intervals of COVID-19 vaccine efficacy rates with a Bayesian framework. Under the classical approach, there is no probability associated with a parameter, and the meaning of confidence intervals can be misconstrued by inexperienced students. With Bayesian statistics, one can find the posterior probability distribution of an unknown parameter, and state the probability of vaccine efficacy rate, which makes the communication of uncertainty more flexible. We use a hypothetical example and a real baseball example to guide readers to …

Investigating Alignment In A Quantitative Literacy Course For Social Sciences Students, Vera Frith, Pam Lloyd

Numeracy

The Numeracy Centre at the University of Cape Town has taught a one-semester quantitative literacy course for social sciences students since 1999. This study aims to provide an example for how the design of such a course can be assessed for alignment with quantitative reasoning goals. We propose a framework of learning outcomes for the course and use that framework to analyse the assessments and student performance on them. We find that just under half of the overall mark for the course was devoted to the interpretation and communication of quantitative information (our “main” outcomes), and about a quarter was …

An Astronomer’S Journey Into Quantitative Reasoning, Jeffrey Bennett

Numeracy

The University of Colorado Boulder campus introduced what may have been the world’s first quantitative reasoning (QR) requirement in 1984 and started offering a QR course in 1988. Although I am an astronomer by training, I had the privilege of creating and teaching that course, which led to my co-authorship of the first textbook directed specifically at QR courses. In this “Roots and Seeds” piece, I will discuss how this course and textbook came to be, how I as an astronomer ended up involved in it, and how this work has connected with other aspects of my career.

Simplified But Not The Same: Tracing Numeracy Events Through Manually Simplified Newsela Articles, Ellen C. Agnello

Numeracy

New York-based education startup Newsela has quickly gained popularity with K-12 educators in the six years since its launch. Its website boasts that it serves 90% of schools in the United States including the 1.5 million teachers they employ and their 20 million students. But what makes it so popular? Teachers are drawn to its Common Core-aligned informational texts which facilitate content-area connections while exposing students to important current events. Likely the most appealing aspect of the platform is its compatibility with differentiation, as it makes available five iterations of each article at varying levels of complexity or Lexile which …

How Social Workers Count: Numbers And Social Issues Came To Be, Michael A. Lewis

Numeracy

Lewis, Michael Anthony. 2019. Social Workers Count: Numbers and Social Issues (New York: Oxford University Press) 224 pp. ISBN 978-0190467135.

This essay introduces Social Workers Count: Numbers and Social Issues by Michael Anthony Lewis. Inspired by the seminal work of Bennett and Briggs, Lewis shares how he came to write a math book for social workers to meet new demands as the field has developed to include more quantitative concepts. The result is a book that may be of interest to many in the quantitative reasoning movement in the social sciences and beyond.

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 …
