SyllabusStatement

Boise State's Foundational Studies Program provides undergraduates with a broad-based education that spans the entire university experience. MATH 123 Quantitative Reasoning satisfies three credits of the Foundational Studies Program's Disciplinary Lens-Mathematics (DL-M) requirement. It supports the following University Learning Outcomes, along with a variety of other course-specific goals:
7. Apply knowledge and the methods of reasoning characteristic of mathematics, statistics, and other formal systems to solve complex problems.
MATH 123: Quantitative Reasoning is designed to introduce students to the methods of reasoning used in science and mathematics. This course helps to achieve the goals of the Foundational Studies Program by focusing on the following course learning outcomes. After successful completion of this course, you will be able to:

• Assess data for reasonableness
• Create and interpret graphical information
• Appreciate the statistical techniques used in studies and experiments
• Recognize the characteristics of exponential growth
