Appropriate use of concepts Appropriate use of terminology Representation of a situation as a function Accurate graphical representation of a function Correct choice and application of differential techniques Use of algebraic operations in conformity with rules Accuracy of calculations Correct interpretation of results Explanation of steps in problem-resolution procedure Elements of the Competency: Specific Performance Criteria Introduction: Calculus I is the first of the required mathematics courses in the Science Program. It is usually taken in the first semester. Calculus I introduces the student to the limit process that is so vital to the development of differential calculus. Since differential calculus is a basic tool in Physics, some of the applications will be related to problems in Physics. To a lesser extent, differential calculus can be applied to problems in Chemistry and Biology. The primary purpose of the course is the attainment of objective 00UN ("To apply the method of differential calculus to the study of functions and problem solving"). To achieve this goal, this course must help the student understand the following basic concepts: limits, continuity and derivatives involving realvalued functions (algebraic, trigonometric, exponential and logarithmic) of a single variable. Emphasis will be placed on clarity and rigour in reasoning and in the application of methods. The student will learn to interpret the derivative both as a mathematical tool and as a rate of change. The derivative will be used in various contexts that include velocity, acceleration, curve sketching, optimization and related rates. The basic concepts are illustrated by applying them to various problems where their application helps arrive at a solution. In this way the course encourages the student to apply learning acquired in one context to problems arising in another. Towards the end of the course, the student will be introduced to antiderivatives in order to help with the transition from Calculus I to Calculus II. Students will be encouraged to use a scientific graphing calculator; however, only scientific non-graphical calculators will be permitted on tests and the final exam. Students will also have access to the Mathematics Lab where suitable mathematical software programs including MAPLE 6 are available for student use. The course uses a standard college level Calculus textbook, chosen by the Calculus I and Calculus II course committees. 1. To recognize and describe the characteristics of a function expressed in symbolic or graphic form. 2. To determine whether a function has a limit. To determine whether a function is continuous at a point or on an interval. To determine whether a function is differentiable at a point or on an interval. 3. To apply the rules and techniques of differentiation. 4. To use the derivative and related concepts to analyze the variations of a function and to be able to graph it. 5.

Specific performance criteria for each of these elements of the competency are shown below with the corresponding intermediate learning objectives. For the items in the list of learning objectives it is understood that each is preceded by: "The student is expected to…".

TEACHING METHODS This course will be 75 hours, meeting three times a week for a total of 5 hours a week. Most teachers of this course rely mainly on the lecture method, although most also employ at least one of the following techniques as well: question-and-answer sessions, labs, problem-solving periods and class discussions, Generally, each class session starts with a question period of previous topics, then new material is introduced, followed by worked examples. No marks are deducted for absenteeism (however, see below). Failure to keep pace with the lectures results in a cumulative inability to cope with the material, and a failure in the course. A student will generally succeed or fail depending on how many problems have been attempted and solved successfully. It is entirely the student's responsibility to complete suggested homework assignments as soon as possible following the lecture, as the material will be fresher in his/her mind. This also allows the student the maximum benefit from any discussion of the homework (which usually occurs in the following class). The answers to a selected number of problems can be found in the back of the text. Each teacher will provide supplementary notes and problems as he/she sees fit. MATH WEBSITE: http://www.johnabbott.qc.ca Go to Student Zone, Departments, Mathematics MATH LAB: The Math Lab is located in H-203 and is open from 11:00 to 16:00 for borrowing course material or using the computers and printers for math assignments. Page 5 MATH HELP CENTRE: There is usually a teacher available for individual help (see posted schedule) The Math Help Centre is located in H-203 from 9 to 11:00 and in H-222 after 11:00. MATH TUTORING CENTRE: Peer tutoring is available in the Math Lab. The schedule is usually posted around the 4th week of each semester on the Math Lab bulletin board. LEARNING CENTRE The Learning Centre, located in H-117A , offers student skills classes and individual tutoring. DEPARTMENTAL ATTENDANCE POLICY Regular attendance is expected. Missing six classes is grounds for automatic failure in this course. Many of the failures in this course are due to students missing classes. EVALUATION PLAN ( a) A student's Final Grade is a combination of the Class Mark and the mark on the Final Exam. The class mark will be 75% (three to five tests) and 25% at you instructor’s discretion (more tests, quizzes or assignments). The specifics of the Class Mark will be given by your instructor in the last page or during the first week of classes. Every effort is made to ensure equivalence between the various sections of the course. The Final Exam is set by the Course Committee (which consists of all instructors currently teaching this course), and is marked by each individual instructor. ( b) The Final Grade will be whichever is the better of: 50% Class Mark and 50% Final Exam Mark OR 25% Class Mark and 75% Final Exam Mark A student CHOOSING NOT TO WRITE the Final Exam will receive a failing grade of 50% or their class mark, whichever is less. COURSE COSTS In addition to the cost of the text listed above, your instructor might recommend you acquire an inexpensive scientific calculator ($10-$25). No graphing or programmable calculators are allowed during tests or the final exam. COLLEGE POLICY ON CHEATING AND PLAGIARISM Cheating and plagiarism are unacceptable to John Abbott College. Students are expected to conduct themselves accordingly and must be responsible for all their actions. For more information on Cheating and Plagiarism, students should consult the Institutional Policy on the Evaluation of Student Achievement (IPESA), which is reprinted in the College Calendar or Student Agenda. COLLEGE POLICY ON MID-SEMESTER ASSESSMENT Students in their first and second semester have the right to feedback on basic skills in the first weeks of the semester so that they can seek extra help if necessary. Notice to Students on GRADE REVIEW It is the responsibility of students to keep all assessed material for at least one month past the grade review deadline in the event that they would want to request a grade review. Students can learn more about their rights and responsibilities by reading the IPESA.
