Course Title:Introduction toCalculus (Level 3)
Length of Course:One Year (5 credits)
Prerequisites:Precalculus
Description:
This course presents apreliminary introduction to Calculus for students who will likely specialize in business, economics, management, life and social sciences. Calculus plays an important role in these areas. It is the mathematics of change and we, of course, live in a constantly changing world. The goal of this course is to equip students with the powerful tools of Calculus. At the foundation of mathematics is the idea of a function. Functions express the way one variable quantity is related to another quantity. Calculus was invented to deal with the rate at which a quantity varies, particularly if that rate does not stay constant. Clearly, this course needs to begin with a thorough review of functions, particularly the properties, behavior and manipulation of the polynomial function. However, reviewing should be accomplished through the lens of calculus. This should be engaging because it is a different, but a unifying way to look at all the functions. Beyond review, students will construct a firm understanding of the derivative and its applications.
This courseis designed to give students a proper balance between the mastery of skills and the comprehension of key concepts. This curriculumwill be guided by two principles. The first is the Rule of Three which requires that every topic be presented geometrically, numerically and algebraically. The second guiding principle is the Way of Archimedes which states that formal definitions and procedures evolve from the investigation of practical problems. Specifically, this curriculum provides many problems that are applications of the Social Sciences, Life Sciences and Business arenas and are generally accepted as important. This course exceeds requirements specified in the CCSS and State Standards.
Evaluation:
Student performance will be measured using a variety of instructor-specific quizzes and chapter tests as well as departmental common assessments, Midterm and Final Exam. Assessments will balance the degree to which required concepts and skills have been mastered.
