The remarkable effectiveness of mathematics to reveal and quantify patterns in every human discipline makes a degree in mathematics enormously valuable and versatile. The department offers a major that prepares students for a myriad of careers, ranging from business to industry to government to secondary education, as well as for graduate school. Non-majors may obtain a minor in mathematics. Visit the department at http://www.sbu.edu/math.
MATH-099 DEVELOPMENTAL MATHEMATICS (3 Credits)
The course is intended for students who need to improve their fundamental knowledge of basic arithmetic and algebra skills before they can be successful in the mathematics course required for their major. Topics will include fractions, decimals, signed numbers, percents, ratios and proportions, linear and polynomial expressions, equations, and graphs. Applications are emphasized throughout in preparation for further study in mathematics and other disciplines which involve quantitative problems. Students will be placed into this course by the Mathematics Department based on a combination of high school record, SAT/ACT scores, and/or placement exam score. This course will not satisfy the quantitative reasoning requirement for Clare College. Students may not enroll in this course if they have successfully completed any college mathematics course.
MATH-107 INTRODUCTION TO STATISTICS (3 Credits)
This course is a non-calculus-based study of statistics, including descriptive methods, basic probability theory, some design and data-collection issues, and procedures for statistical inference. Topics on statistical inference include confidence intervals and hypothesis testing for means and proportions along with chi-squared tests. Emphasis is on set-up and interpretation rather than on computation, with a significant reliance on computer software and/or statistical calculators for the "number crunching" portion of the analysis. Students mays not receive credit for both MATH 107 and MATH 117. MATH 107 includes all content in MATH 117 except ANOVA, and consequently moves at a slower pace than MATH 117.
MATH-108 PRECALCULUS (3 Credits)
This course provides a detailed study of topics needed for success in calculus: algebra, trigonometry, analytic geometry, and functions. Intended for students who need to take at least one semester of calculus for their major.
MATH-111 MATHEMATICS OF ELEMENTARY EDUCATION I (3 Credits)
This course, in conjunction with Math 112, is intended to give pre-service elementary school teachers a deep understanding of the mathematical systems that they will be expected to teach. The content of Math 111 includes the arithmetic systems of the whole numbers, the integers, and the rationales (at least in fraction form). For each system, students are expected to understand not only how to perform the four arithmetic operations, but also to understand what those operations accomplish in real life, why the operations work the way they do, and how to model or represent those operations in concrete or semi-concrete ways. The study of the integers will include some basic number theory concepts. Underlying all topics in Math 111 are the notions of estimation and mental arithmetic, problem solving, mathematical communication, and viewing mathematics as a logical and sensible system rather than a set of memorized procedures. Intended for elementary education majors. Offered Fall.
MATH-112 MATHEMATICS FOR ELEMENTARY EDUCATION II (3 Credits)
This course is a continuation of Math 111, with the same philosophy and emphasis on achieving a deep understanding of elementary school mathematics. The content for Math 112 includes the real number system (as comprised of terminating, repeating, and non-repeating decimals), percents and proportions, probability, descriptive statistics, measurement (in English, metric, and non-standard units), and an overview of basic terminology and concepts from geometry. Intended for elementary education majors. Offered Spring.
Prerequisite(s): Take MATH-111
MATH-117 INTRODUCTION TO STATISTICS FOR NATURAL SCIENCE MAJORS (3 Credits)
This non-calculus-based study of statistics includes descriptive methods, basic probability theory, some design and data-collection issues, and procedures for statistical inference. Topics on statistical inference include confidence intervals and hypothesis testing for means and proportions, Chi-squared tests, and one-way and two-way ANOVA. Emphasis is on set-up and interpretation rather than on computation, with a significant reliance on computer software and/or statistical calculators for the "number crunching" portion of the analysis. Students mays not receive credit for both MATH 107 and MATH 117. MATH 117 includes all content in MATH 107, but moves at a faster pace to allow for the inclusion of the ANOVA topics.
