Dominican International School PRECALCULUS GRADE EVEL: 11 1 Year, 1 Credit TEACHER: Yvonne Lee SY: 2017-2018 email: ylee@dishs.tp.edu.tw COURSE DESCRIPTION Pre-Calculus serves as a transition between algebra and calculus. This course covers many important fundamental concepts that will prepare students for calculus and college-level mathematics. Students are expected to understand, analyze, and utilize basic functions. They are also expected to understand the relationship between exponential functions and logarithm. Trigonometric functions and identities will be included and students are expected to graph and analyze graph and prove identities. Analytic geometry in two dimension and discrete mathematics will also be covered. TEACHING STRATEGIES This course emphasizes on algebraic, numeral, graphical, and verbal methods of representing problems. Therefore, one or all of these four approaches will be applied in every section to enhance students understanding. With the use of the graphic calculator, the teacher can invite students to participate more in forming answer to a question by looking at the graph and interpreting data on the calculator. Relating real-life problems to this course is also essential to help students understand concepts because students tend to only memorize the formula for the test and then forget everything they learned after the test. When students can see the linkage between real-life situation and mathematic topics, they will be able to remember and apply for later use. STUDENT ACTIVITIES Students will participate in class activities such as discussions and presentations. Students are encouraged to answer questions orally or on the board. In every quarter, students will work in groups to present a solution to a real-life problem with poster or power point. Students will also practice questions from Khan Academy. ASSESSMENT This course will be assessed on the following three categories: class participation and homework, tests and quizzes, and the quarter exam. Each category weighs one-third of each quarter s academic grade. Students attitude and behavior during the class time will be graded and recorded in the deportment grade.
