AB Calculus Course Syllabus Course overview: The goal of this course is for students to become mathematically proficient all topics included in first semester college Calculus. This mathematical proficiency includes conceptual understanding, comprehending the concepts, operations, and relations in Calculus, procedural fluency, the ability to accurately and efficiently complete the procedures involved in Calculus, strategic competence, the ability to formulate, represent, and solve mathematics problems involving Calculus concepts, adaptive reasoning, the ability to carry out logical thought, reflection, and justification, and productive disposition, seeing mathematics as useful along with the belief in one’s own efficacy.

Class Culture: A large part of the AP Calculus program is dependent on building a classroom culture in which the students feel safe in sharing their ideas and frustrations. The AP classroom should be a place where students work together using synergy to accomplish higher achievement as a class than they could as individuals. This culture is intentionally created through several means. Students begin the year by reading an article titled “Building a Mathematical Culture’ from Connected Geometry, Teacher’s Guide, Everyday Learning Corporation, 2000. They also read a synopsis of The Habits of Mind, Association for Supervision and Curriculum Development, 2000. The students get involved in weekly before and after school help session aptly named “Calculus Parties.” At these sessions students bring snack food and work together to complete problems and master concepts. Students also attend a quarterly movie in the evening at a local Arts Theater where they view and discuss math related movies like Stand and Deliver, A Beautiful Mind, and Good Will Hunting. These things contribute to a sense of community within the AP Calculus program, encouraging students to work together in learning Calculus. Required Components Multiple Representations of Functions: The course goals are accomplished by creating a classroom culture in which students work together to investigate, discuss, explain, justify, and reflect on the topics of Calculus. The development of each topic includes multiple representations; graphical, verbal, numerical, and analytical. Most topics are introduced in context verbally and developed graphically first to encourage a conceptual understanding before any analytical approach is applied. This is usually followed by a numerical approach to the topic which is finally developed into the more abstract analytical approach. Through out the course students are presented problem situations given in any of the four representations and to connect their understanding of the topic among the different representations. Communication: Students communicate verbally as they work in groups to investigate new concepts, to solve problems, and to process homework. They also communicate verbally through problem presentations to their peers as well as a project presentation each semester in which they present a larger problem or present a new topic to their peers and their parents. Students communicate in written form when they write justification for homework problems, when they are asked to explain their work as part of a test questions, and when they complete there AP Packet at the end of each unit. Each unit ends with a packet of five or six released, free-response AP questions that connect current learning with previous learning. All of these packets are scored on the 9 point AP scale and must include justification for complete credit. Technology: Almost every lesson involves the incorporation of graphing calculator technology. Our purpose is to use the graphing calculator as a vehicle for understanding the Calculus. Because of that, graphing calculator techniques for differentiation, integration, and general algebraic analysis is done concurrently or even prior to paper and pencil analytical approaches. All tests are 50% with a graphing calculator and 50% without a graphing calculator. Computer technology is also incorporated, although on a less frequent basis. Students use Geometer’s Sketchpad to visualize some of the problems. Students also have the opportunity to use Maple software in the semester projects. Content: All AP Calculus AB topics are covered in this course. This can be seen in the unit and lesson syllabus given on the following pages.

(Functions Modeling Change, Connally) Lessons should be approached as a quick review with the idea that concepts from these lessons will be reviewed and revisited as they arise in the Calculus content. Lesson 7 on Continuity is new and is approached from a purely intuitive perspective in the first unit. The note to students on page xi serves as a good introduction to the rule of four, the format of the book, and the philosophical approach authors. Some time should be spent during this unit on setting individual and class goals in regards to the course and the AP test. Every test, beginning with unit 1, consists of four parts divided into calculator and non-calculator as well as multiple choice and free-response. Functions and Change Exponential Functions Transformation of Functions Logarithmic Functions Trigonometric Functions Power, Polynomial, & Rational Functions Continuity of Functions Unit 1 Review/ Check Your Understanding Unit 1 Test Key Concept: The Derivative: This unit introduces the concept of the derivative as student transition form “average rate of change” used in Precalculus to “instantaneous rate of change.” Slope as a way of measuring rate of change is introduced as the main theme for the first semester of the course. Students estimate derivatives graphically and calculate derivatives numerically by finding the limit of the average rates of change for successively closer points. They also learn the difference between the derivative at a point and the derivative function. The numerical derivative function on the calculator is introduced in this unit after students see derivatives as the limit of average derivatives. Beginning with this unit, the review at the end of each chapter will include the chapter review, the true-false conceptual check up in “Check Your Understanding”, and some AP practice from released free-response questions. The AP practice should be scored using the 9 point AP scoring guide. Measuring Speed Limits The Derivative at a Point The Derivative Function Interpretation of the Derivative The Second Derivative Continuity and Differentiability Unit 2 Review/ Check Your Understanding/ AP Review Chapter Two Test Short-Cuts to Differentiation: In this unit students expand their conceptual understanding of derivatives to include algebraic procedures for differentiation. These rules are “discovered” using graphical and numerical methods and, when appropriate, are justified analytically. The technique of implicit differentiation is also introduced. The tangent line formula in lesson 3-9 is presented as a point-slope form equation rather than a formula. Students are encouraged to use and appreciate the efficiency of the point slope form. Graphing calculators are used to illustrate local linearity and the closeness of the fit of the tangent line near the point of tangency.

Some applications are given with parameters that challenge the students in terms of their algebraic skills. Geometer’s Sketchpad is used to investigate or demo the families of functions in lesson 4-2. Some problems that students have seen in Geometry and Precalculus, like minimizing the surface area of a Coke can or minimizing the cost of laying a power line under a river, are redone using differentiation techniques. 4-1; Using Derivatives 4-2; Families of Curves 4-3; Optimization 4-5; Optimization & Modeling 4-7; Theorems Unit 4 Review/ Check Your Understanding/ AP Review Unit 4 Test Semester 1 Projects: Students are given a list of possible projects or are invited to propose one of their own. The projects offer an opportunity to apply first semester Calculus concepts learned in semester in solving more in-depth problems that take more than one class period to complete. The students, working with a partner, write up their problem and solution on a display board and present it to the class. Key Concept: The Integral: Students are introduced to the definite integral through using velocity-time graphs to find distance. Dimensional analysis is used to connect integrals and areas of rectangles. Students work with Riemann Sums as a way of estimating integrals. The Riemann Sums are used in numerical, graphical, and algebraic contexts. The programs CRIEMANN and DRIEMANN are linked to student graphing calculators for use in finding Riemann Sums with a large number of intervals. For lesson 5.3, example 1 in the Instructor’s Manual provides an excellent in-class investigation of a graphical approach in deducing information using functions, derivatives, and integrals. Lesson 5-4 introduces the Fundamental Theorem of Calculus, connecting derivatives (semester 1) with integrals (semester 2). Students are introduced to the calculator’s definite integral function in 5-2.

Integration by Parts (lesson 7.2) is done after the AP test as it is often part of Calculus 1 in a college course, but is not part of the AP test for AB Calculus. Partial fraction decomposition is not covered in this course. (All of these are covered in the Calculus BC course.) Integration by Substitution Approximating Definite Integrals Unit 7 Review/ AP Review Unit 7 Test Using the Definite Integral: The main focus of this unit is finding volumes of revolution. The approach taken is to find the find the volume of one slice, write a Riemann sum representing all slices and convert it to integral notation. Lessons 8.5-8.7 offer applications to science, business, and statistics. These lessons are offered as student project options after the AP exam. Area and Volume by Integration Volume of Revolution and Length Density Using Integrals Applications to Physics Unit 8 Review/ Check Your Understanding/ AP Review Unit 8 Test Differential Equations: Students are introduced to more involved differential equations with separable variables. Slope fields are introduced as a graphical solution to a differential equation. Slope fields are introduced by students working together to make a slope field on a large set of coordinate axes. They then do slopefields by hand and on the calculator. Differential Equations Slope Fields Separation of Variables Growth and Decay Applications and Modeling Chapter 11 Review/ Check Your Understanding/ AP Review Unit 11 Test AP Test Practice: Students spend any remaining time before the AP exam working released AP problems and tests, including multiple choice and free-response. Students spend any remaining time before the AP exam working released AP problems and tests, including multiple choice and free-response. A schedule of “Calculus Parties” is set before school, after school, and in the evening after extra-curricular practices, for students to get together and discuss the review problems. About one week prior to the exam, students take and actual full-length released test in a mock-testing situation. Test results are used to pinpoint individual strengths and weaknesses and to determine focus areas for the final week of preparation. Integration by Parts Semester 2 Projects: Students are given a list of possible projects or are invited to propose one of their own.
