Methods Of Instruction

A combination of different instructional methods will be used in order to balance instructional efficiency with individual student needs.  Group instruction, individual assistance in lab tutorial or scheduled appointments and student-directed learning will be selected where appropriate and possible.

Course Description
This course deals with a variety of topics in geometry, trigonometry, and algebra--including relations and functions - and is equivalent to the curriculum for B.C. Schools Mathematics 11. It is designed for students who plan to take further courses in mathematics for transfer credit. Topics include: quadratics; factoring expressions requiring grouping, rational expressions and complex fractions, quadratic equations using the quadratic formula, rational equations and formula rearrangement, radical equations, exponential equations with related bases, relations and functions, direct and inverse variation, sketching graphs and functions, graphing techniques and the determination of equations, and trigonometry.

Means of Assessment

Attendance is a course requirement.  The final grade may be UN if more than 30% of classes are missed or if less than 70% of items for evaluation are undertaken.

Evaluation will be based on examinations and assignments in accordance with college policy.  Details regarding the number and weighting of individual components will be announced in a "Course Information" handout at the beginning of the semester.

Textbook Materials

Students are required to supply a three-ring binder, paper, pen, pencil and a scientific calculator with direct algebraic logic (D.A.L. or S.-V.P.A.M.).

Main textbooks will be available on loan from the library to registered students.  A course pack for this course must be purchased from the bookstore.
