Student Learning Outcomes

  • Students will solve application problems (drawn from business, economics, medicine, engineering,education, psychology, sociology, social sciences, life science, and health science) through the application of quantitative reasoning strategies, including but not limited to investigation, modeling, analysis, multiple representations of numbers and functions, estimation, dimensional analysis, and probabilistic reasoning.
  • Students will write about and discuss solutions to contextualized, quantitative problems using notation and statements that are correct and complete.

Description

This course is designed for any student, in any major, who is interested in exploring the connections between math concepts and the quantitative skills we use in everyday life. The course focuses on problem solving using mathematical methods and modeling and quantitative investigation strategies. Applications include linear and exponential models, multivariable relationships, conversions, estimation, elementary probability, and descriptive statistics. Students will learn individually and collaboratively to analyze quantitative information and apply quantitative skills in a variety of real life contexts and express their findings verbally and in writing.

Course Objectives

The student will be able to:

  1. Create, apply, and interpret linear and exponential models to solve problems in contextualized, culturally relevant settings.
  2. Calculate, compare, and interpret measures of center to make decisions.
  3. Apply quantitative reasoning strategies to culturally relevant applications drawn from business, economics, medicine, engineering, education, psychology, sociology, social sciences, life science, and health science.
  4. Use estimation and investigation of multiple representations of numbers and functions to assess claims from a variety of fields, such as environmental, health and wellness.
  5. Analyze personal finance options.
  6. Use graphs to describe, interpret, synthesize, and predict.
  7. Analyze multivariable relationships and investigate what variables contribute to the formula.
  8. Practice mathematical habits of mind.
  9. Select appropriate mathematical tools to solve problems and make decisions.
  10. Discuss mathematical problems and write solutions in accurate mathematical language and notation.
