4 1. INTRODUCTION This Definition of the Domain for Summative Evaluation describes and classifies the essential and representative elements of the secondarylevel adult education Mathematics program and, more specifically, of the course entitled Factoring and Algebraic Fractions. As such, it gives an overview of the program, but should by no means replace the program itself. The purpose of defining the domain is to ensure that all summative evaluation instruments are consistent with the overall program. The Definition of the Domain for Summative Evaluation for each course in this program is organized in a similar manner; however, the content of this definition of the domain is specific to the course entitled Factoring and Algebraic Fractions. The goal of the Definition of the Domain for Summative Evaluation is to prepare examinations that are valid from one version to another or from one school board to another, taking into account the responsibilities shared by the Ministère de l Éducation and the school boards. Factoring and Algebraic Fractions MTH
5 . PROGRAM ORIENTATIONS AND CONSEQUENCES FOR SUMMATIVE EVALUATION ORIENTATIONS The main objective of the secondarylevel adult education Mathematics program is to help students fully understand mathematical concepts. The program also aims to improve the students ability to clearly relate information using mathematical language. The program is intended to help students develop a systematic work method. The program will help students master the use of technological tools. CONSEQUENCES Evaluation should involve verifying whether the student has fully understood the different concepts. Evaluation items should involve performing tasks that require the use of mathematical language. The appropriateness and clarity of the language used should be taken into account in the marking process. Evaluation items should require the students to present their work in a clear and structured manner. This should be taken into account in the marking process. The use of a scientific calculator is permitted for the examinations related to this course. Factoring and Algebraic Fractions MTH

CONTENT OF THE PROGRAM FOR PURPOSES OF SUMMATIVE EVALUATION Concepts Factoring finding the common factor factoring by grouping factoring a trinomial of the form x + bx + c or of the form x + bxy + cy factoring a trinomial of the form ax + bx + c or of the form ax + bxy + factoring a binomial representing the difference of two squares factoring a polynomial into three prime factors cy Rational algebraic fractions simplification product of two algebraic fractions quotient of two algebraic fractions sum of two algebraic fractions difference of two algebraic fractions equivalence of two algebraic expressions Skills Each skill is defined within the context of a mathematics program. Operating Performing a given operation or transformation. Possible actions: to calculate, construct, break down, perform, estimate, evaluate, isolate, measure, reconstruct, solve, draw, transform, verify, and so on. Analyzing Demonstrating, in an organized fashion, the complex connections between concepts or definitions and their related actions and illustrations. Possible actions: to conclude, correct, deduce, derive, demonstrate, explain, extrapolate, infer, justify, and so on. Factoring and Algebraic Fractions MTH

8 5. OBSERVABLE BEHAVIOURS Examination items should be formulated on the basis of the observable behaviours listed below. The requirements and restrictions specified in the dimensions and the objectives of the program must be observed. Dimension 1 Find the common factor of all the terms of a polynomial containing no more than six terms. Dimension Factor a polynomial by grouping. The polynomial should contain no more than six terms. Dimension 3 Factor a trinomial of the form x + bx + c or of the form x + bxy + cy. Dimension 4 Factor a trinomial of the form ax + bx + c or of the form ax + bxy + cy.

Dimension 8 Simplify a rational algebraic fraction whose numerator and denominator are factorable polynomials containing no more than three terms. Each term contains no more than two variables. Simplifying the fraction involves two or three factorizations. If two factorizations are required for the same polynomial, then one of these must involve finding the common factor. The students must clearly show all their work. Dimension 9 Simplify the product of two rational algebraic fractions. The polynomials of the numerators and denominators contain no more than three terms. Each term contains no more than two variables. Simplifying the product involves two or three factorizations.

The common denominator should consist of no more than two binomials and one monomial. The students must clearly show all their work. (operating) /10 Factoring and Algebraic Fractions MTH
10 Dimension 1 Simplify the difference of two rational algebraic fractions. Simplifying the difference involves no more than one factorization. One numerator and one denominator of the fractions are monomials. The common denominator should consist of no more than two binomials and one monomial. The students must clearly show all their work. (operating) /10 Dimension 13 Verify the equivalence of two algebraic expressions by simplifying the expression containing the sum or the difference of two rational algebraic fractions. Simplifying the expression involves no more than three factorizations. The common denominator should consist of no more than two binomials and one monomial. The students must clearly show all their work. (analyzing) /10 Dimension 14 Verify the equivalence of two algebraic expressions by simplifying them. Each expression contains the sum or the difference of two rational algebraic fractions. Simplifying the expressions involves no more than three factorizations.

11 6. JUSTIFICATION OF CHOICES In the examination, 80% of the items test the students OPERATING skills by verifying whether they have mastered certain operations or transformations: factoring methods simplifying algebraic fractions multiplying two algebraic fractions dividing two algebraic fractions adding two algebraic fractions subtracting two algebraic fractions In the examination, 0% of the items test the students skill in ANALYZING information; they involve verifying whether the students have the ability to make connections: by verifying the equivalency of two algebraic expressions Factoring and Algebraic Fractions MTH
12 7. DESCRIPTION OF THE EXAMINATION A. TYPE OF EXAMINATION The summative examination will be a written examination consisting of short or extendedresponse items. The items should take into account the restrictions and the requirements specified in the dimensions and the objectives of the program. The weighting of marks should be consistent with the percentages set out in the table of dimensions. B.
