Underlying Principles for Revision • Equity focuses on meeting the diverse learning needs of students and promotes excellence for all by – ensuring curriculum expectations are grade and destination appropriate, – by providing access to Grade 12 mathematics courses in a variety of ways. – supporting a variety of teaching and learning strategies Identify 3 key points from your article segment. What is one idea from the classroom that reminds you of these ideas? Underlying Principle for Revision • Effective teaching of mathematics requires that the teacher understand the mathematical concepts, procedures, and processes that students need to learn and use a variety of instructional strategies to support meaningful learning; Mathematical Proficiency Mathematical Proficiency Mathematical Proficiency Representing Problem Solving Reflecting Communicating Reasoning and Proving Connecting Selecting Tools and Computational Strategies Mathematical Processes Mathematical Proficiency Teaching Mathematical Expert Pedagogical Expert Teachers use • strong subject/discipline content knowledge • good instructional skills • strong pedagogical content knowledge Teacher Student Curriculum Student Pedagogical Content Knowledge • Applying subject knowledge effectively, using concepts in ways that make sense to students Teacher: What is the area of a rectangle with length 5 units and width 3 units? Teacher: What is the perimeter of this rectangle? Student: 16 Pedagogical Content Knowledge • Applying subject knowledge effectively, using concepts in ways that make sense to student Teacher: What is the sin 30° + sin 60° ? Student: sin 90° Teacher: Is f(x) + f(y) always equal to f(x+y)? A Problem Solving Moment Problem: What is the sin 50° ? Answer: Wrinkles, Grey Hair, Memory Loss Teaching: Student Engagement Students develop positive attitudes when they • make mathematical conjectures; • make breakthroughs as they solve problems; • see connections between important ideas.

Frayer Model 3 Groups Definition Facts/Characteristics •Grade 7/8 •Grade 9/10 •Grade 11/12 FUNCTIONS Examples Non Examples Conceptual Understanding “Conceptual understanding within the area of functions involves the ability to translate among the different representations, table, graph, symbolic, or real-world situation of a function” (O’Callaghan, 1998).

Poverty increasing: Reports says almost 30 per cent of Toronto families live in poverty. • The report defines poverty as a family whose after-tax income is 50 percent below the median in their community, taking family size into consideration. • In Toronto, a two-parent family with two children living on less than $27 500 is considered poor. METRO NEWS November 26, 2007 Should mathematics be taught the same way as line dancing? A Vision of Teaching Mathematics • Classrooms become mathematical communities rather than a collection of individuals • Logic and mathematical evidence provide verification rather than the teacher as the sole authority for right answers • Mathematical reasoning becomes more important than memorization of procedures. NCTM 1989 A Vision of Teaching Mathematics • Focus on conjecturing, inventing and problem solving rather than merely finding correct answers. • Presenting mathematics by connecting its ideas and its applications and moving away from just treating mathematics as a body of isolated concepts and skills. NCTM 1989 Traditional Lessons Direct Instruction: teaching by example. The “NEW” Three Part Lesson. •Teaching through exploration and investigation: •Before: Present a problem/task and ensure students understand the expectations. •During: Let students use their own ideas. Listen, provide hints and assess. •After: Engage class in productive discourse so that thinking does not stop when the problem is solved. Teaching: Investigation Direct Instruction “ Effective mathematics teaching requires understanding what students know and need to learn and then challenging and supporting them to learn it well” Teaching The problem is no longer just teaching better mathematics. It is teaching mathematics better. Adding It Up: National Research Council - 2001 Underlying Principles for Revision • Curriculum expectations must be coherent, focused and well articulated across the grades; Identifying Key Ideas about Functions • • • • Same groups as Frayer Model Activity Using the Ontario Curriculum, identify key ideas about functions. Describe the key ideas using 1 – 3 words. Record each idea in a cloud bubble on chart paper.
