Course Description

Explores concepts and applications of logic rules, basic probability and statistics as well as personal finance models. Investigates problem solving techniques (algebraic and nonalgebraic) as well as some nontraditional mathematics topics such as social choice or discrete mathematics. Integrates technology where appropriate. The PCC Mathematics Department recommends that students take MTH courses in consecutive terms. Prerequisites: (MTH 95 or MTH 98) and (RD 115 and WR 115) or IRW 115 or equivalent placement. Audit available.

Addendum to Course Description

Math in Society is a rigorous mathematics course designed for students in Liberal Arts and Humanities majors.  The course provides a solid foundation in quantitative reasoning, symbolic reasoning, and problem solving techniques needed to be a productive, contributing citizen in the 21st century.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Use formulas and perform relevant calculations pertaining to personal finance in order to make informed financial decisions
  2. Make and interpret calculations and graphical displays of numerical data in order to perceive and infer patterns within data sets
  3. Calculate and interpret theoretical and empirical probabilities in support of making predictions and decisions in the presence of uncertainty
  4. Use logical reasoning to describe and critique arguments and recognize common logical fallacies
  5. Support conclusions using logical thought, reflection, explanation and justification
  6. Use appropriate representations to effectively communicate, orally and in writing, quantitative results and mathematical processes

Course Activities and Design

All activities will follow the premise that formal definitions and procedures evolve from the investigation of practical problems. It is the goal of this class that the investigation of practical problems will drive a desire to learn the mathematics necessary to understand and explain the practical application.   In-class time is primarily activity/discussion emphasizing problem solving techniques. Activities will include group work.

Outcome Assessment Strategies

  1. At least one individual or group project culminating in a written report and/or an oral presentation. 
  2. In-class exam: proctored, closed book examination
  3. At least two of the following additional measures:
    1. Take-home examinations
    2. In-class exams
    3. Graded homework
    4. Quizzes
    5. In-class activities
    6. Portfolios
  4. Optional Additional Assessment Strategies
    1. Individual student conference
    2. Attendance
