Mathematics and Computer Science

Mathematics and the mathematical patterns found throughout our surroundings offer us a powerful and beautiful way of viewing the world. The St. Stephen’s Mathematics Department seeks to enable students to recognize and assimilate mathematical relationships and use them to make predictions and draw conclusions. The department’s objectives are to:

  • Stimulate curiosity about the application of mathematics in the world around us;
  • Foster independent, creative, and critical thinking in a cooperative learning environment;
  • Develop students’ ability to persevere in the face of difficulty;
  • Encourage articulate communication of ideas in oral and written form;
  • Promote the use of technology in the learning of mathematics; and
  • Cultivate solid foundational skills necessary for complex mathematical analysis.

The curriculum serves students with varying abilities, enabling them to gain confidence in and expand their mathematical skills and to become effective problem solvers and communicators of mathematical ideas. Students develop logical reasoning and critical analysis skills and an appreciation for the beauty and unified structure of mathematics. 

Students are required to complete three mathematics credits and take math through their junior year.  

Advanced sections cover the subject in greater depth and breadth and are designated as such on students’ transcripts. Admission to and retention in an advanced course is by departmental approval and may require confirmation of ability by a placement examination.
  • Algebra I

    Algebra I integrates knowledge of variables and their use with concepts and operations of arithmetic in a formal, logical development of elementary algebra. Accuracy and precision are essential components of instruction, as is the development of problem-solving strategies. The content of the course includes an in-depth study of linear equations and inequalities, graphing, operations with polynomials, factoring, rational expressions and equations, introduction to functions, radical expressions and equations, and the quadratic formula. Word problems and applications of increasing complexity are addressed throughout the course. 
  • Geometry

    Students are introduced to traditional plane and solid Euclidean geometry as well as coordinate geometry, constructions, and transformational geometry. Both independent problem-solving and cooperative group work are elements used in the investigation of geometric truths. Students learn theory and application, formal and informal proofs, and symbolic and visual approaches to problems. The course provides a firm foundation in understanding the relationships between and within geometric figures, and it develops the skills to reason effectively. Computer-assisted explorations, as well as compass and straightedge constructions, are part of the course throughout the year as they relate to the topics covered. The course helps to prepare students for the challenges of higher-level mathematics.

  • Introduction to Computer Science

    Introduction to Computer Science exposes students to computer programming through structured programming and object-oriented programming paradigms. The course assumes no prior programming experience and begins with a “boot camp” in which students learn the basic elements of computer programming (algorithms, variables, arrays, functions, iteration, and conditional statements) and practice the use of those structures by writing short console applications. The course expands into a broader examination of efficiency, concision, objects, APIs, and data structures, with many short assignments to cement understanding of new concepts and with opportunities for students to create computer games with graphics and other graphical projects. Emphasis is given to hands-on learning with an effort to minimize lecture.  Students will develop the ability to think like a programmer and interpret a problem or goal in a way that the problem or goal can be modeled with software components. The course prepares students for the Advanced Computer Science course.

    Prerequisite: Geometry. 
    1 credit 
  • Adv Computer Science

    Students continue the study of computer science topics primarily in the Java programming language. Topics in this course include the design of solutions to problems, the use of advanced algorithms and data structures, and the analysis of code through case studies. Students will primarily use an Object Oriented design that will require utilization of boxing, data encapsulation, inheritance, and polymorphism. The course will conclude with an individual student-driven study of a topic agreed upon by both student and instructor.  

    V- or higher in Introduction to Computer Science or departmental approval.
