What is Teaching Quantitative Reasoning with the News?

• Using newspaper articles as content for the critical analysis of quantitative information.

• Quantitative comparisons, graphical analyses, and elementary modeling can all be approached and supported with case studies based on media articles.

• The daily newspaper has numerous examples illustrating the need to be able to deal critically with quantitative information in today's society.

Why Teach Quantitative Reasoning with the News?

• Creates a more exciting learning atmosphere by using variable content, a healthy dose of unpredictability, and exposure to numerous non-mathematical topics;

• Gives numerical topics a real context.• Indicates the relevance and importance of

quantitative reasoning to– present day issues as well as– everyone’s lives

• Naturally allows a teacher to spiral through important themes.

News of the Day

• Students bring in current news articles (that are of interest to them) and present a short synopsis that explains the main point of the article, critiques the presentation/analysis of the quantitative information, and details how the article is similar or different to articles that we have studied.

• How often? Do a few every day. Size of the class determines how many times an individual will present.

• Create a rubric that fits your purposes. The rubric may change during the semester.
