Course Overview

Functions and Relations, Grade 11, University Preparation, MCR3U

Prerequisite:  Principles of Mathematics, Grade 10, Academic

Course Description

This course introduces some financial applications of mathematics, extends students’ experiences with functions and trigonometry, and introduces second-degree relations. Many of the expectations of this course are based on direct extensions of concepts introduced in Grades 9 and 10. Having previously explored linear and quadratic relationships, students study polynomial and rational functions, and investigate the relationship between functions and their inverses. Students continue their study of trigonometry and discover new properties and contexts to which it can be applied. Graphing and algebraic skills are also consolidated and extended in this course. Identifying connections between the algebraic and graphic representations of functions continues to be an important skill.

Successful completion of MCR3U Functions and Relations will prepare students for any of the five Grade 12 University and College Preparation courses, and provides the necessary foundation for mathematically rich university programs. In particular, this course should be taken by students who are planning to study engineering, computer science, pure mathematics, or the physical sciences at the university level. This course shares a core set of expectations with the Grade 11 Functions course, MCF3M, which is comprised of three strands: Financial Applications of Sequences and Series, Trigonometric Functions, and Tools for Operating and Communicating with Functions. Completion of either of these two Grade 11 programs will prepare students for the Grade 12 courses Advanced Functions and Introductory Calculus (MCB4U), Mathematics of Data Management (MDM4U), Mathematics for College Technology (MCT4C), and College and Apprenticeship Mathematics (MAP4C). In addition to this common core, the Functions and Relations course contains some extension to the core plus a fourth strand, Investigations of Loci and Conics, which provides students with the knowledge and skills necessary for MGA4U, Geometry and Discrete Mathematics.

In addition to the Investigations of Loci and Conics strand and operations on complex numbers, the MCR3U course differs from the MCF3M course in timing and context. The pace of delivery in MCR3U will require students to consistently demonstrate the ability to:

·         investigate and construct mathematical concepts independently;

·         conjecture and, through inquiry, test a hypothesis;

·         generate multiple types of solutions to complex problems which may cross strands, require the use of appropriate technology, and require abstract thinking (e.g., the consideration of cases);

·         expand the depth of their inquiry in order to solve higher-order problems;

·         analyse and design proofs from multiple perspectives.

Because of the destination intended for students enrolled in MCR3U, the contextual examples and activities should be drawn largely from the areas of engineering, the physical sciences, computer science, and pure mathematics.

In the Financial Applications of Sequences and Series strand, students will acquire the tools required to make sound personal financial decisions. Students will investigate and solve problems involving applications of sequences related to compound interest, annuities, and financial decision-making. In the Trigonometric Functions strand, students will investigate and apply properties of the primary trigonometric functions and develop a competency in the manipulation of these functions. This strand has been divided into two units: Trigonometry (covering radian measure and the sine and cosine laws) and Trigonometric Functions (with particular emphasis on the study of sinusoidal functions). The Tools for Operating and Communicating with Functions strand allows students to develop skills in operating with various algebraic expressions and to develop facility in using function notation and in communicating reasoning. This strand has also been divided into two units: Exploring Functions: Connecting Algebra and Geometry and Function Notation, Inverses, and Transformations. In the Investigations of Loci and Conics strand, students will extend their inquiry of loci into a study of conics. Students will become proficient in two- and three-dimensional modelling, which is essential to achieving success in MGA4U, Geometry and Discrete Mathematics.

How This Course Supports the Ontario Catholic School Graduate Expectations

This course encourages the Catholic learner to develop his/her God-given gifts and abilities to promote growth toward personal responsibility in preparation for a chosen career path. Throughout this course, emphasis should be placed on moral, ethical, and realistic decision-making in an effort to build responsible citizenship. The classroom environment should instil a spirit of cooperation, rather than competition amongst students, and should foster a collaborative sense of community. This course provides many opportunities for students to work effectively as interdependent team members and to acknowledge others for their opinions.

Course Notes

This course profile builds on previous mathematics course profiles written for Grades 9 and 10. The Grade 11 course profiles produced by the Catholic and Public systems represent a collaborative effort between the two writing teams. While not as detailed as the Grade 9 and 10 profiles, each is designed to complement and supplement the other. Due to the common core of learning expectations between the MCR3U and MCF3M courses, a common unit breakdown has been suggested, and four different sample units have been developed. Thus, the MCR3U and MCF3M course profiles can also be used as complementary resources. With appropriate adjustments to the complexity of problems and the need for abstract thinking, activities from either profile can be used by a teacher of either course. It should be noted that in this course, it is appropriate in certain situations for mathematics itself to provide the context for new concepts, while in MCF3M it would be more appropriate to provide other contexts as well. The sample units provided in this (MCR3U) profile are Exploring Functions: Connecting Algebra and Geometry and Trigonometric Functions, while the sample units provided in the MCF3M profile are Function Notation, Inverses, and Transformations and Financial Applications of Sequences and Series. In addition to these four complete “sample” units, a less-detailed Unit Overview chart offers a recommended clustering of expectations for each of the remaining units, providing a starting point from which teachers can develop their own, individualized units.

For some students, mathematics is perceived to be a collection of isolated and complex topics, each requiring skills that may soon be forgotten. The mathematics teacher must address these perceptions by creating a context in which students can learn and connect concepts and skills. Students must be exposed to a variety of teaching, learning, and problem solving techniques to best synthesize the information presented by the curriculum, and should be provided applications and context to bring meaning to their learning.

The activities in this profile are designed to both introduce and consolidate skills necessary for success in this course. These activities can be used in conjunction with or independently of one another. Alternate teaching strategies and suggestions for technological tools are included to help teachers present the lessons contained in the activities.

Because this course has been designed to prepare students for further mathematical studies at university, the specific nature of the learning activities should reflect this destination. In particular, students in this course should routinely be challenged with investigations and problems which require sustained, independent effort. Students destined for university should have the opportunity to develop and demonstrate a high level of complex problem-solving ability.

Students with learning disabilities will need specific guidance in order to benefit from the investigative approach presented in this profile. Review of prerequisite skills and instructions in the use of technology, and in particular graphing calculators, will be required before any activities are begun. Clear and precise instructions with examples will need to be provided.

Several of the activities presented in this profile include extensions of the required content, which can be used to meet the need to challenge gifted students. Other accommodations may include allowing for student preferences in supplemental learning, altering the pace of instruction, creating a flexible classroom environment, and using specific instructional strategies. Creative approaches to problem solving must be encouraged.

The Achievement Chart for Mathematics is the basis of all assessment and evaluation for this course. The Principles of Mathematics – Academic (Grade 10) Public Course Profile includes charts suggesting strategies that can be used for the assessment and evaluation of all categories of the Achievement Chart (p. 11). In addition, a chart outlining the component actions that are needed for successful inquiry and problem solving in particular is also included in their profile (p. 12). These charts provide an excellent base with which to begin the implementation of these strategies, and for teachers of this course to extend, depending on their degree of readiness. Another excellent resource is the Concerning Assessment and Reflective Evaluation (CARE) package of materials, available for free download at http://www.oame.on.ca. Among the resources included in this package are generic rubrics for Communication and Thinking/Inquiry/Problem Solving skills, along with suggested applications of these instruments.

Unit Description

Students investigate quadratic functions and related concepts from algebraic and geometric perspectives, in order to deepen their understanding and prepare them for further explorations of functions and relations. A winter recreation theme is loosely woven throughout selected activities in the unit, providing a contextual framework for students to solve problems, both with and without the use of graphing technology. Students solve first-degree inequalities and graph their solutions on number lines. Skills involving operations with polynomials and rational expressions are consolidated, and then extended to the complex number system, which is introduced in this unit. Students apply the method of completing the square in order to solve maximum/minimum problems involving quadratic functions. Algebraic and graphical methods are used to determine the roots of quadratic equations. The exponent laws are applied to expressions which have powers containing integer and rational exponents. Students discover the nature of exponential functions and solve exponential equations.

Unit Description

Students investigate the concept of locus of points, using dynamic geometry software. Conic sections are introduced as second-degree relations, containing some examples that are not functions. Physical models (e.g., string models, sketches) representing conic sections are constructed, which serve to illustrate their geometric properties. By translating to standard position, students identify conic sections by type, given their equations. Students determine the intersection of lines and conics, and solve problems involving the application of conics.

Unit Description

Summative assessment should be designed to provide the opportunity for students to demonstrate comprehensive learning in each of the four achievement categories. Some ideas are suggested in the chart that follows, however any of the various assessment tools mentioned in the Assessment Strategies section could be used. A short paper-and-pencil task would review key terms, skills, and concepts. Investigations comparing the buying and leasing of a car yield a wide variety of applications pertaining to both personal finance and the modelling of functions. An assignment exploring trigonometric inverses (for example, the arcsine function) would serve to review the concepts introduced in the functions and trigonometry units. This topic also provides students with an exposure to a subject further explored in Grade 12. An additional activity linking the conics and trigonometry strands (using the unit circle and parametric equations, perhaps) could also be designed. These topics are suggested as one possible way to revisit the expectations in a new mathematical context. Accordingly, students are to be assessed solely on the expectations of this course, and not on the extension topics themselves. Due to the particular emphasis of cumulative tests and examinations in university and college programs, a formal examination should be play a prominent role in the final summative assessment of the student.

Some Considerations for Alternate Delivery Models

Because of the similarity of the learning expectations of the MCR3U and MCF3M courses, it is possible that some schools may run split classes, combining both courses in the same room. While this situation should be avoided wherever possible, timetabling issues may make it impossible to have separate classrooms for each of these two courses. Therefore, in order to satisfy the needs of all students in this situation, the following delivery model, patterned after the scope and sequence of the MCF3M Course Profile, is proposed.

Note that the Investigations of Loci and Conics unit is to be delivered largely as an independent study, throughout the length of the course. Only students enrolled in MCR3U would be required to complete this unit. The teacher should provide instructional support where necessary. It is suggested during these times that the teacher have MCF3M students otherwise engaged in activities designed to consolidate skills in the three core strands.

As the times for the remaining units have all been increased, it is expected that the pace of the delivery of course will be appropriately altered. This will allow MCR3U students time to expand the depth and scope of their inquiry and problem-solving skills relating to relevant subject matter. The Financial Applications of Sequences and Series unit can be delivered either before or after the two trigonometry units, depending on the students’ needs.

Teaching/Learning Strategies

In order to address the wide range of expectations in this course, a variety of teaching, learning, and assessment strategies and tools need to be used. Teachers should assume a variety of roles (including guide, facilitator, consultant, and instructor), and should employ a variety of strategies including:

·         a balance of whole-class, small group, mixed-ability structured group, and individual instruction through student-centred and teacher-directed activities (group work should be carefully structured along cooperative learning principles to be effective);

·         the use of rich contextual problems which engage students and provide them with opportunities to demonstrate learning, and appreciate the need for new skills;

·         the prompting, supporting, and challenging of individual students as well as the class as a whole;

·         approaches that will accommodate multiple learning styles (e.g., the provision of verbal and written instructions, the inclusion of hands-on activities, etc.);

·         the use of technological tools and software (e.g., graphing software, dynamic geometry software, the Internet, spreadsheets, and multimedia) in activities, demonstrations, and investigations to facilitate the exploration and understanding of mathematical concepts;

·         the use of learning/performance tasks that are designed to link several expectations and give the students occasion to demonstrate their optimal levels of achievement through the demonstration of skill acquisition, the communication of results, the ability to pose extending questions following an inquiry, and the determination of a solution to unfamiliar problems;

·         the use of accommodations, remediation, and/or extension activities, where necessary, to meet the needs of exceptional students;

·         the provision of opportunities for students to practise and extend their skills and knowledge outside of the classroom.

In addition to the contribution of the teacher, students themselves should play an active role in their own learning. In order to successfully complete the requirements of this course, students are expected to:

·         develop an increased responsibility for their own learning;

·         be accountable for prerequisite skills;

·         participate as active learners;

·         engage in explorations using technology;

·         apply individual and group learning skills;

·         describe mathematical patterns that emerge verbally, algebraically, and visually in the course of learning.

Assessment tools such as observational checklists, performance criteria, rubrics, The Achievement Chart for Mathematics, marking schemes, rating scales, peer evaluation, and self-evaluation can and should be used to assist in developing objective and consistent evaluations of student achievement.

Assessment & Evaluation of Student Achievement

Assessment, as defined in the document Ontario Secondary Schools, Grades 9-12: Program and Diploma Requirements, 1999, is “the process of gathering information from a variety of sources (including assignments, demonstrations, projects, performances, and tests) that accurately reflects how well students are achieving the curriculum expectations” (p. 31). Assessment tools should be designed to allow students to demonstrate the full extent of their learning across the four categories of knowledge and skills. As teachers will use a variety of assessment tools, it is necessary to ensure that a consistent standard is maintained. These tools should be developed with the learning expectations of the course as the criteria for this standard. Thus, a grade of 70-79% using an objective marking scheme should be equivalent to a Level 3 performance, as defined by the Achievement Chart. Teachers may find it more appropriate to use rubrics to assess Thinking/Inquiry/Problem Solving, and Communication skills, but to use objective scales for Knowledge/Understanding, and Application skills. High-quality assessment can measure individual and group performance, and individual performance within a group.

The students’ effective demonstration of communication skills is an essential component of this course when evaluating achievement. Students are required to display and convey their knowledge and understanding of concepts, share their process of thought and inquiry, and justify their application of concepts in an unfamiliar situation. In addition, their ability to communicate these skills is also assessed.

It should also be noted that teachers must continue to expand their understanding of Application skills to include non-routine applications. This view requires a shift from the specific application of concepts (i.e., familiar situations), to the general application of concepts (i.e., unfamiliar situations).

Assessment strategies and tools must address a wide variety of teaching and learning styles in addition to the criteria established by the learning expectations. Tests consisting only of questions that ask students to perform algorithms and apply their knowledge do not necessarily offer an opportunity for students to demonstrate Level 4 performance.

Also, it is understood that students will meet course expectations at a variety of performance levels. An effective and well-balanced assessment program will provide students with several opportunities to demonstrate growth and improvement over time, across all of the knowledge and skill categories.

Evaluation, as defined by Ontario Secondary Schools, Grades 9-12: Program and Diploma Requirements, 1999, is “the process of judging the quality of a student’s work on the basis of established achievement criteria, and assigning a value to represent that quality” (p. 31). Whereas assessment is the collection of information about student performance in a variety of methods, evaluation is the determination of a quantitative value describing the student’s overall level of achievement. Effective assessment, evaluation, and reporting require the teacher to do more than just average marks. While averaging may be more useful in some Knowledge and Application skill categories, it is not comprehensive enough for accurate reporting in the Inquiry and Communication skill categories. The use of rubrics is a suggested technique for these categories. As students can be expected to improve their performances over time, particular emphasis should be placed on their most recent and most consistent level of achievement.

Students who receive a final performance evaluation of Level 3 or better are well prepared for work in the university preparation courses Geometry and Discrete Mathematics (MGA4U), Advanced Functions and Introductory Calculus (MCB4U), and Mathematics of Data Management (MDM4U). Accordingly, in order to prepare students for the academic reality of most mathematically rich university programs, proper attention should be placed on the students’ effective preparation for a comprehensive final examination. While other rich, performance-based activities can and should be part of the Final Summative Assessment unit, a formal examination should play a significant role in this particular course.

Seventy per cent of the grade will be based on assessments and evaluations conducted throughout the course. Thirty per cent of the grade will be based on a final evaluation in the form of an examination, performance, essay, and/or other method of evaluation.

Accommodations

Teachers should refer to the students’ Individual Education Plans (IEP) and consider their particular learning characteristics to make any necessary accommodations. Teachers should work in consultation with resource teachers, ESL/ELD teachers, and parents or guardians to determine appropriate accommodations as they work through the course in order to achieve the IEP expectations.

Accommodations for ESL/ELD Students

·         Have ESL students work in pairs, with peer tutors, with classmates that have the same linguistic background, or with cooperative supportive groups, where they are more likely to improve their use of English. Brainstorm in groups using the students’ first language if their usage of English is limited.
