3 Rhetoric NY Times (5/15/06) In traditional math, children learn multiplication tables and specific techniques for calculating. In constructivist math, the process by which students explore the question can be more important than getting the right answer, and the early use of calculators is welcomed.

4 NCTM Focal Points (9/12/06) September 12 Wall Street Journal article did not represent the substance or intent of the focal points. The focal points are not about the basics; they are about important foundational topics. NCTM has always supported learning the basics. Students should learn and be able to recall basic facts and become computationally fluent, but such knowledge and skills should be acquired with understanding.

5 Education Week 11/1/06 We cannot afford to waste time on polarization. What is important is that we pragmatically address critical target areas to improve mathematics education. We cannot be distracted from our primary mission—to match tactical initiatives in other, newly technological societies that are snatching our competitive advantage in innovation—while we bicker over modest differences in approach. (Jere Confrey)

6 Motivating Factors for Change Society’s hate for mathematics that is prevalent and acceptable –4 out of 10 adults hate mathematics* (twice as many people said they hated math as said that about any other subject) International test scores Industry concerns (no problem solving skills) National Council of Teachers of Mathematics (NCTM) Standards *2005 AP-AOL News poll

9 Third International Math & Science Study (TIMSS) Procedures vs. Concepts
10
10 Stated vs Developed
11
11 Lesson Study Demonstrates a procedure Assigns similar problems to students as exercises Homework assignment Presents a problem without first demonstrating how to solve it Individual or group problem solving Compare and discuss multiple solution methods Summary, exercises and homework assignment
12
12 We need a BALANCE Traditional text with conceptual supplement Conceptual text (EM, CMP, Core- Plus) with computational supplement
13
13 Conceptual Understanding 24 ÷ 4 = 6 24 ÷ 3 = 8 24 ÷ 2 =12 24 ÷ 1 = 24 24 ÷ 1/2 = ??
14
14 Fractions - Conceptually More than 1 or Less than 1 Explain your reasoning The F word
15
15 Which is larger? 2/3 + 3/4 + 4/5 + 5/6 OR 4 12.5 x 45 OR 4.5 x 125 1/3 + 2/4 + 2/4 + 5/11 OR 2
16
16 Where’s the Point? 2.43 x 5.1 = 12393 4.85 x 4.954 = 240269 21.25 x 1.08 = 2295 1.25 x 64 = 80 4.688 x 1.355 = 635224 46.88 x 1.355 = 635224 4.688 x 135.5 = 635224 46.88 x 13.55 = 635224

27 Contextual Problem Solving Not more traditional word problems Placing mathematical lessons into settings Giving students a reason to learn the skill Motivating students

39 Implications & Inferences NJ Assessments are rigorous and conceptual NJ Math Standards are well aligned with NJ assessments Most districts have a well aligned curriculum –Then, what’s wrong?
40
40 Algebra Placement Districts should not encourage all students to take Algebra I in grade 8; students should be taking Algebra I in grade 8 only if they are highly motivated, have a strong foundation in middle school mathematics, receive high grades in previous courses, intend to study calculus in high school, and only if the Algebra I courses are taught by teachers with mathematics certification.
