1 Translating the Vision of the 9-12 Common Core State Standards into Highly Effective H.S. Math Programs The Leona Group May 23, 2011 Steve Leinwand American Institutes for Research

3
Agenda 8:15 – 9:00 - District Leadership – Perspectives, leadership opportunities and timelines 9:15 – 11:00 – ALL – Why bother? Glimpses and implications of the CCSSM 11:15 – 12:15 – Coaches and teachers – Doing the math 12:45 – 3:00 – Coaches and teachers – Instruction and professional collaboration 2

4
Opening Gambit Your knowledge, experience, insights, creativity, energy and expertise are desperately needed to improve K-12 mathematics education. (If you don’t feed inadequate…..) 3

5
People won’t do what they can’t envision, People can’t do what they don’t understand, People can’t do well what isn’t practiced, But practice without feedback results in little change, and Work without collaboration is not sustaining. Ergo: your job, as leader, at its core, is to help people envision, understand, practice, receive feedback and collaborate. The key things we know 4

6
And one key perspective: Most teachers practice their craft behind closed doors, minimally aware of what their colleagues are doing, usually unobserved and under supported. Far too often, teachers’ frames of reference are how they were taught, not how their colleagues are teaching. Common problems are too often solved individually rather than by seeking cooperative and collaborative solutions to shared concerns. (this SOP won’t help us in the coming years) 5

7
Critical next steps Build familiarity with the CCSSM Course by course discussions Professional collaboration Crosswalks The mathematical practices Think 15% per year Focus on instructional quality/opportunity to learn 6

8
Rollout Timeline, hopefully : A year of comprehensive planning (clarifying what needs to be done when) : A year of study (analyzing crosswalks, curricular implications, policy shifts) : A year of piloting and collaborative discussions : A year of curriculum and policy implementation and an assessment moratorium : A year of accountable implementation 7

9
So what can we do? Potential structures for professional sharing: Structured and focused department meetings Before school breakfast sessions Common planning time – by grade and by department Pizza and beer/wine after school sessions Released time 1 p.m. to 4 p.m. sessions Hiring substitutes to release teachers for classroom visits Coach or principal teaching one or more classes to free up teacher to visit colleagues After school sessions with teacher who visited, teacher who was visited and the principal and/or coach to debrief Summer workshops Department seminars 8

10
So what can we do? Potential Strategies for developing professional learning communities: Classroom visits – one teacher visits a colleague and the they debrief Demonstration classes by teachers or coaches with follow-up debriefing Co-teaching opportunities with one class or by joining two classes for a period Common readings and CCSSM sections assigned, with a discussion focus on: –To what degree are we already addressing the issue or issues raised in this article? –In what ways are we not addressing all or part of this issue? –What are the reasons that we are not addressing this issue? –What steps can we take to make improvements and narrow the gap between what we are currently doing and what we should be doing? 9

11
So what can we do (cont.)? Technology demonstrations (graphing calculators, SMART boards, document readers, etc.) Collaborative lesson development Video analysis of lessons Analysis of student work Development and review of common finals and unit assessments What’s the data tell us sessions based on state and local assessments What’s not working sessions Principal expectations for collaboration are clear and tangibly supported Policy analysis discussions, e.g. grading, placement, requirements, promotion, grouping practices, course options, etc. 10

12
In other words Reduce the professional isolation Enhance the transparency of our work To raise the quality of what we do 11

13
Discussion Question Which of these CAN’T you do and why? 12

14
Agenda 8:15 – 9:00 - District Leadership – Perspectives, leadership opportunities and timelines 9:15 – 11:00 – ALL – Why bother? Glimpses and implications of the CCSSM 11:15 – 12:15 – Coaches and teachers – Doing the math 12:45 – 3:00 – Coaches and teachers – Instruction and professional collaboration 13

15
Today’s Little Goals Provide some perspectives on the array of problems with the current high school math program. Provide more than a glimmer of hope thanks to the new CCSS for Mathematics. Provide a range of examples of current and future practice. Present some of the implementation issues that will need to be faced. 14

16
Today’s Big Goal To provoke and inform your thinking about the need and directions for significantly revising the traditional Algebra I, Geometry, and Algebra II courses to ensure relevance, real rigor and fairness that truly meets the needs of all students. 15

17
Economic security and social well-being Innovation and productivity Human capital and equity of opportunity High quality education (literacy, MATH, science) Daily classroom math instruction Where we fit on the food chain 16

18
Opening Premise Mediocre mathematics achievement and unacceptably stark achievement gaps are the symptom – not the problem. If we conceive of it as an “achievement” gap, then it’s THEIR problem or fault. Alternatively, it is a system failure, the heart of which is modal instruction that fails to provide adequate opportunity to learn, that is the problem. If we conceive of it as an “instruction” gap, then it’s OUR problem or fault. 17

19
18 The System Problem A depressingly comprehensive, yet honest, appraisal must conclude that our typical math curriculum is generally incoherent, skill-oriented, and accurately characterized as “a mile wide and an inch deep.” It is dispensed via ruthless tracking practices and focused mainly on the “one right way to get the one right answer” approach to solving problems that few normal human beings have any real need to consider. Moreover, it is assessed by 51 high-stakes tests of marginal quality, and overwhelmingly implemented by under-supported and professionally isolated teachers who too often rely on “show-tell-practice” modes of instruction that ignore powerful research findings about better ways to convey mathematical knowledge.

20
Quite a mouthful and not a pretty picture. But when little of what we do works for more than 30% of our students; And when most of us really aren’t comfortable putting our own kids in many more than 30% of available classrooms; We’ve got work to do! 19

21
So let’s take a look at some context-setting sound bites or perspectives: 20

22
21 1) Let’s be clear: We’re being asked to do what has never been done before: Make math work for nearly ALL kids and get nearly ALL kids ready for college. There is no existence proof, no road map, and it’s not widely believed to be possible.

23
22 2) Let’s be even clearer: Ergo, because there is no other way to serve a much broader proportion of students: We’re therefore being asked to teach in distinctly different ways. Again, there is no existence proof, we don’t agree on what “different” mean, nor how we bring it to scale. (That’s the hope of the CCSS for Math)

24
3) The pipeline perspective: 1985: 3,800,000 Kindergarten students 1998: 2,810,000 High school graduates 1998:1,843,000 College freshman 2002: 1,292,000 College graduates 2002: 150,000 STEM majors 2006: 1,200 PhD’s in mathematics (the best case I know for math for normal standards vs. the 43+ math for nerds) 23

25
4) A critical perspective As mathematics colonizes diverse fields, it develops dialects that diverge from the “King’s English” of functions, equations, definitions and theorems. These newly important dialects employ the language of search strategies, data structures, confidence intervals and decision trees. - Steen 24

26
5) Another critical perspective Evidence from a half-century of reform efforts shows that the mainstream tradition of focusing school mathematics on preparation for a calculus-based post- secondary curriculum is not capable of achieving urgent national goals and that no amount of tinkering in likely to change that in any substantial degree. - Steen 25

27
Non-negotiable take-away Make no mistake, for K-12 math in the U.S., this IS brave new world. 26

28
Full disclosure For better or worse, I’ve been drinking the CCSSM Kool-aid. Leinwand on the CCSSM in the 2011 Heinemann catalog. 27

29
A Long Overdue Shifting of the Foundation For as long as most of us can remember, the K-12 mathematics program in the U.S. has been aptly characterized in many rather uncomplimentary ways: underperforming, incoherent, fragmented, poorly aligned, unteachable, unfair, narrow in focus, skill-based, and, of course, “a mile wide and an inch deep.” Most teachers are well aware that there have been far too many objectives for each grade or course, few of them rigorous or conceptually oriented, and too many of them misplaced as we ram far too much computation down too many throats with far too little success. It’s not a pretty picture and helps to explain why so many teachers and students have been set up to fail and why we’ve created the need for so much of the intervention that test results seem to require. But hope and change have arrived! Like the long awaited cavalry, the new Common Core State Standards (CCSS) for Mathematics presents us – at least those of us in the 44 states that have now adopted them (representing over 80% of the nation’s students) – a once in a lifetime opportunity to rescue ourselves and our students from the myriad curriculum problems we’ve faced for years. COHERENT FAIR TEACHABLE 28

30
So to high school and the task at hand: 29

31
My First Premise As currently implemented, high school Algebra 1, Geometry, and Algebra 2 are not really working and meeting neither societal or student needs. 30

32
A brief justification for my premise: Increasingly obsolete and useless symbol manipulation focus at the expense of functions, models, applications, big ideas and statistics An impossible to “cover” scope and sequence 1200 page tomes 1 st half of Algebra 2 = 2 to 1 dilation of Algebra 1 Extraordinarily high failure rates Turns millions off to mathematics Designed for a very narrow slice of the cohort Neither relevant, rigorous, nor fair! 31

33
In blunter terms: No wonder HS math is often referred to as “a rotten geometry sandwich stuffed between two stale slices of algebra” 32

34
My Second Premise The 9-12 Common Core State Standards have the potential to resolve many of these problems. 33

35
Some perspectives to support my first premise 34

36
35 Just for fun… Simplify: 45 √2 + √7 - 9 (√2 - √7) Actual retail value: 11.08

37
36 Versus substance too rarely addressed If 0 < x < 1, which of the following is greatest? a)1/x b)√x c)x d)x 2 -What if x > 1? -What if x < -1?

38

42
A little synthetic division perhaps? Or perhaps you would prefer ignoring all of the technological advances of the past 25 years and just do some factoring for fun? Talk to engineers about what math they use and how they do it 41

43
To summarize our expectations…. Simplify Solve Factor Graph vs. Simplify Solve Factor Graph Find Express Display Model Represent Solve Predict Demonstrate 42

44
And what are the outcomes? Achieve ADP Algebra I 2009 Exam 33,446 students (KY, OH, RI and NJ) Level Scale Score % of Students Advanced % Proficient % Basic % Below Basic % Ave. Scale Score: 384 ( ) 43

45
And what are the outcomes? Achieve ADP Algebra II 2009 Exam 102,396 students (13 states, 60% AZ & IN) Level Scale Score % of Students Well –prepared % Prepared % Needs preparation % Ave. Scale Score: 1032 ( ) 44

46
Additional ADP Findings On both the Algebra I and Algebra II exams, students earned, on average, only 11% and 14%, respectively, of the possible points available on constructed-response items. On the Algebra II exam in both 2008 and 2009, nearly one-third of the students earned no points on the 2-point or 4-point constructed response items. And we claim they’re ready for the 21 st century??? 45

47
So Why Bother? Look around. Our critics are not all wrong. Mountains of math anxiety Tons of mathematical illiteracy Mediocre test scores HS programs that barely work for half the kids Gobs of remediation A slew of criticism Not a pretty picture and hard to dismiss 46

48
Yes, Virginia or Houston or whoever, WE HAVE A PROBLEM!!! (and no amount of tinkering around the edges is going to fix it) 47

49
Enter the new Common Core State Standards for Mathematics (www.corestandards.org) Not perfect, but clearer, fairer, and more coherent 48

50
The Math Field of Activity The heart of ensuring instructional quality and producing high levels of student achievement includes four key elements: A coherent and aligned curriculum that includes a set of grade level content expectations, appropriate print and electronic instructional materials, with a pacing guide that links the content standards, the materials and the calendar; High levels of instructional effectiveness, guided by a common vision of effective teaching of mathematics and supported by deliberate planning, reflection and attention to the details of effective practice; A set of aligned benchmark and summative assessments that allow for monitoring of student, teacher and school accomplishment at the unit/chapter and grade/course levels; and Professional growth within a professional culture of dignity, transparency, collaboration and support. (What, how, how well and with what support to do it better) 49

51
But….as we need to acknowledge Our curriculum is stale, Our instruction is underperforming, Our assessments are mediocre, and Our professional development is essentially useless! 50

52
BUT…Great News Our curriculum is stale – enter CCSSM Our instruction is underperforming, Our assessments are mediocre – enter SBAC/PARCC Our professional development is essentially useless! Welcome to a far more simplified world. 51

53
The Reduced Field of Activity (in the CCSS Era) The heart of ensuring instructional quality and producing high levels of student achievement includes four key elements: A coherent and aligned curriculum that includes a set of grade level content expectations, appropriate print and electronic instructional materials, with a pacing guide that links the content standards, the materials and the calendar; High levels of instructional effectiveness, guided by a common vision of effective teaching of mathematics and supported by deliberate planning, reflection and attention to the details of effective practice; A set of aligned benchmark and summative assessments that allow for monitoring of student, teacher and school accomplishment at the unit/chapter and grade/course levels; and Professional growth within a professional culture of dignity, transparency, collaboration and support. (What, how, how well and with what support to do it better) 52

54
So finally, let’s take a look at the game changer: The Common Core State Standards for Mathematics 53

55
Promises These Standards are not intended to be new names for old ways of doing business. They are a call to take the next step. It is time for states to work together to build on lessons learned from two decades of standards based reforms. It is time to recognize that standards are not just promises to our children, but promises we intend to keep. — CCSS (2010, p.5) 54

56
Characteristics of the CCSS Fewer, therefore teachable Fair, therefore expectable Aligned with college and career expectations Internationally benchmarked Rigorous content and application of higher-order skills – rigor as depth, not complexity Learning progressions that build coherence and mastery expectations Research-based Common – finally! 55

57
CCSSM Mathematical Practices The Common Core proposes a set of Mathematical Practices that all teachers should develop in their students. These practices are similar to NCTM’s Mathematical Processes from the Principles and Standards for School Mathematics. 56

58
8 CCSSM Mathematical Practices 1.Make sense of problems and persevere in solving them. 2.Reason abstractly and quantitatively. 3.Construct viable arguments and critique the reasoning of others. 4.Model with mathematics. 57

59
8 CCSSM Mathematical Practices 5.Use appropriate tools strategically. 6.Attend to precision. 7.Look for and make use of structure. 8.Look for and express regularity in repeated reasoning. 58

HS: Six conceptual categories Number and Quantity Algebra Functions Modeling Geometry Statistics and Probability 59

61
Common Core Format High School Conceptual Category Domain Cluster Standards K-8 Grade Domain Cluster Standards 60

62
Common Core Format Domains are large groups of related standards. Standards from different domains may sometimes be closely related. Look for the name with the code number on it for a Domain. 61

63
Common Core Format Clusters are groups of related standards. Standards from different clusters may sometimes be closely related, because mathematics is a connected subject. Clusters appear inside domains. 62

64
Common Core Format Standards define what students should be able to understand and be able to do – part of a cluster. 63

Format of High School StandardsStandardStandard ClusterCluster DomainDomain 64

66
High School Pathways Pathway A: Consists of two algebra courses and a geometry course, with some data, probability and statistics infused throughout each (traditional) Pathway B: Typically seen internationally that consists of a sequence of 3 courses each of which treats aspects of algebra, geometry and data, probability, and statistics. 65

67
CCSS 9-12 Algebra Seeing Structure in Expressions Interpret the structure of expressions Write expressions in equivalent forms to solve problems Arithmetic with Polynomials and Rational Expressions Perform arithmetic operations on polynomials Understand the relationship between zeros and factors of polynomials Use polynomial identities to solve problems Rewrite rational expressions Creating Equations Create equations that describe numbers or relationships Reasoning with Equations and Inequalities Understand solving equations as a process of reasoning and explain the reasoning Solve equations and inequalities in one variable Solve systems of equations Represent and solve equations and inequalities graphically 66

68
A closer glimpse at algebra Create equations that describe numbers or relationships 1. Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions. 2. Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales. 3. Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods. 4. Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm’s law V = IR to highlight resistance R. 67

69
CCSS 9-12 Functions Interpreting Functions Understand the concept of a function and use function notation Interpret functions that arise in applications in terms of the context Analyze functions using different representations Building Functions Build a function that models a relationship between two quantities Build new functions from existing functions Linear, Quadratic, and Exponential Models Construct and compare linear, quadratic, and exponential models and solve problems Interpret expressions for functions in terms of the situation they model Trigonometric Functions Extend the domain of trigonometric functions using the unit circle Model periodic phenomena with trigonometric functions Prove and apply trigonometric identities 68

70
A closer glimpse at functions Understand the concept of a function and use function notation 1. Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x). 2. Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context. 3. Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. For example, the Fibonacci sequence is defined recursively by f(0) = f(1) = 1, f(n+1) = f(n) + f(n-1) for n ≥ 1. 69

71
CCSS 9-12 Geometry Congruence Experiment with transformations in the plane Understand congruence in terms of rigid motions Prove geometric theorems Make geometric constructions Similarity, Right Triangles, and Trigonometry Understand similarity in terms of similarity transformations Prove theorems involving similarity Define trigonometric ratios and solve problems involving right triangles Apply trigonometry to general triangles Circles Understand and apply theorems about circles Find arc lengths and areas of sectors of circles Expressing Geometric Properties with Equations Translate between the geometric description and the equation for a conic section Use coordinates to prove simple geometric theorems algebraically Geometric Measurement and Dimension Explain volume formulas and use them to solve problems Visualize relationships between two- dimensional and three-dimensional objects Modeling with Geometry Apply geometric concepts in modeling situations 70

72
A closer glimpse at geometry 1 Similarity, Right Triangles, and Trigonometry Understand similarity in terms of similarity transformations 1. Verify experimentally the properties of dilations given by a center and a scale factor: a. A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged. b. The dilation of a line segment is longer or shorter in the ratio given by the scale factor. 2. Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. 3. Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar. 71

73
A glimpse at geometry 2 Prove theorems involving similarity 4. Prove theorems about triangles. Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity. 5. Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. Define trigonometric ratios and solve problems involving right triangles 6. Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. 7. Explain and use the relationship between the sine and cosine of complementary angles. 8. Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. 72

74
CCSS 9-12 Statistics and Prob Interpreting Categorical and Quantitative Data Summarize, represent, and interpret data on a single count or measurement variable Summarize, represent, and interpret data on two categorical and quantitative variables Interpret linear models Making Inferences and Justifying Conclusions Understand and evaluate random processes underlying statistical experiments Make inferences and justify conclusions from sample surveys, experiments and observational studies Conditional Probability and the Rules of Probability Understand independence and conditional probability and use them to interpret data Use the rules of probability to compute probabilities of compound events in a uniform probability model Using Probability to Make Decisions Calculate expected values and use them to solve problems Use probability to evaluate outcomes of decisions 73

75
A closer glimpse at Statistics Understand and evaluate random processes underlying statistical experiments 1. Understand statistics as a process for making inferences about population parameters based on a random sample from that population. 2. Decide if a specified model is consistent with results from a given data- generating process, e.g., using simulation. For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of 5 tails in a row cause you to question the model? Make inferences and justify conclusions from sample surveys, experiments, and observational studies 3. Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each. 4. Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling. 5. Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant. 6. Evaluate reports based on data. 74

76
But the challenge is how we translate this vision and these words into daily classroom reality 75

77
76 Problem 1 Tell me five things you see. f(x) = x 2 + 3x - 5

78
77 Problem 2 Siti packs her clothes into a suitcase and it weighs 29 kg. Rahim packs his clothes into an identical suitcase and it weighs 11 kg. Siti’s clothes are three times as heavy as Rahims. What is the mass of Rahim’s clothes? What is the mass of the suitcase?

79
78 The old (only) way: Let S = the weight of Siti’s clothes Let R = the weight of Rahim’s clothes Let X = the weight of the suitcase S = 3R S + X = 29 R + X = 11 so by substitution: 3R + X = 29 and by subtraction: 2R = 18 so R = 9 and X = 2

80
79 Or using a model: 11 kg Rahim Siti 29 kg

81
Problem 3 F = 4 (S – 65) + 10 Find F when S = 81 Vs. First I saw the blinking lights… then the officer informed me that: The speeding fine here in Vermont is $4 for every mile per hour over the 65 mph limit plus a $10 handling fee. 80

82
Connecticut: F = 10 ( S – 55) + 40 Maximum speeding fine: $350 Describe the fine in words At what speed does it no longer matter? At 80 mph how much better off would you be in VT than in CT? Use a graph to show this difference 81

83
82 Problem 4 You may or may not remember that the formula for the volume of a sphere is 4/3πr 3 and that the volume of a cone is 1/3 πr 2 h. Consider the Ben and Jerry’s ice cream sugar cone, 8 cm in diameter and 12 cm high, capped with an 8 cm in diameter sphere of deep, luscious, decadent, rich triple chocolate ice cream. If the ice cream melts completely, will the cone overflow or not? How do you know?

Problem 5 Solve for x: 16 x.75 x < 1 Vs. You ingest 16 mg of a controlled substance at 8 a.m. Your body metabolizes 25% of the substance every hour. Will you pass a 4 p.m. drug test that requires a level of less than 1 mg? At what time could you first pass the test? 87

89
88 Big Ideas 1 –Functions are the mathematical rules for taking input (independent variables) and producing output (dependent variables). –Algebraic properties allow the generation of equivalent forms of most expressions and equations. –Linear functions are additive (the dependent variable increases additively); exponential functions are multiplicative (the dependent variable increases multiplicatively). –There is a direct relationship, for any function, among a point on a graph of the function, an ordered pair in a table of the function, and a solution to the symbolic form of the function.

90
89 Big Ideas 2 –Solving equations is an undoing process of equivalent equations based on inverse to isolate the variable, where addition undoes subtraction and vice verse, multiplication undoes division, square rooting undoes squaring. –The graphs of functions can be visualized and predicted based on transformations of a parent function (all linear functions are transformations of the parent function or line y = x; all quadratic functions are transformations of the parent function y = x 2 ). –The graph of the inverse of a function is its reflection across the line y = x. –Just as subtraction undoes, or is the inverse of, addition, the square root is the inverse of squaring and finding a log is the inverse of raising to a power.

Long Reach HS Howard County (MD) recognized that there were a significant number of 9 th graders who were not being successful in Algebra 1. To address this problem, the county designed Algebra Seminar for approximately 20% of the 9 th grade class in each high school. These are students who are deemed unlikely to be able to pass the state test if they are enrolled in a typical one-period Algebra I class. Algebra Seminar classes are: 98

100
Team-taught with a math and a special education teacher; Systematically planned as a back-to-back double period; Capped at 18 students; Supported with a common planning period made possible by Algebra Seminar teachers limited to four teaching periods; Supported with focused professional development; Using Holt Algebra I, Carnegie Algebra Tutor, and a broad array of other print and non-print resources; Notable for the variety of materials and resources used (including Smart Board, graphing calculators, laptop computers, response clickers, Versatiles, etc.); Enriched by a wide variety of highly effectively instructional practices (including effective questioning, asking for explanations, focusing of different representations and multiple approaches); and Supported by county-wide on-line lesson plans that teachers use to initiate their planning. 99

101
100 Jo Boaler’s Work Multidimensional classes “In many classrooms there is one practice that is valued above all others – that of executing procedures (correctly and quickly). The narrowness by which success is judged means that some students rise to the top of classes, gaining good grades and teacher praise, while other sink to the bottom with most students knowing where they are in the hierarchy created. Such classrooms are unidimensional.”

102
101 Jo Boaler’s Work Multidimensional classes “At Railside the teachers created multidimensional classes by valuing many dimensions of mathematical work. This was achieved, in part, by having more open problems that students could solve in different ways. The teachers valued different methods and solution paths and this enabled more students to contribute ideas and feel valued.”

103
102 When there are many ways to be successful, many more students are successful. “When we interviewed the students and asked them “what does it take to be successful in mathematics class?” they offered many different practices such as: asking good questions, rephrasing problems, explaining well, being logical, justifying work, considering answers…

104
103 “When we asked students in “traditional” classes what they needed to do in order to be successful they talked in much more narrow ways, usually saying that they needed to concentrate, and pay careful attention.”

107 Putting it all together one way Good morning class. Today’s objective: Find the surface area of right circular cylinders. Open to page Example 1: S.A.= 2πrh + 2 πr 2 4 Find the surface area. Page odd

109
TIMSS Video Study 2 Teacher presents complex, thought- provoking problem Students struggle with the problem individually and in groups Student present their work Teacher summarizes solutions and extracts important understandings Students work on a similar problem 108

110
109 Putting it all together another way Overheard in the ER as the sirens blare: “Oh my, look at this next one. He’s completely burned from head to toe.” “Not a problem, just order up 1000 square inches of skin from the graft bank.” You have two possible responses: -Oh good – that will be enough. OR -Oh god – we’re in trouble.

111
110 Which response, “oh good” or “oh god” is more appropriate? Explain your thinking. Assuming you are the patient, how much skin would you hope they ordered up? Show how you arrived at your answer and be prepared to defend it to the class.

111 Peter Dowdeswell of London, England holds the world record for pancake consumption! 62 6” in diameter, 3/8” thick pancakes, with butter and syrup in 6 minutes 58.5 seconds! SO?

113
112 So? About how high a stack? Show and explain Exactly how high? How fast? How much? Could it be, considering the size of the stomach? What’s radius of single 3/8” thick pancake of same volume? Draw a graph of Peter’s progress.

Agenda 8:15 – 9:00 - District Leadership – Perspectives, leadership opportunities and timelines 9:15 – 11:00 – ALL – Why bother? Glimpses and implications of the CCSSM 11:15 – 12:15 – Coaches and teachers – Doing the math 12:45 – 3:00 – Coaches and teachers – Instruction and professional collaboration 117

119
So it’s instruction, silly! Research, classroom observations and common sense provide a great deal of guidance about instructional practices that make significant differences in student achievement. These practices can be found in high- performing classrooms and schools at all levels and all across the country. Effective teachers make the question “Why?” a classroom mantra to support a culture of reasoning and justification. Teachers incorporate daily, cumulative review of skills and concepts into instruction. Lessons are deliberately planned and skillfully employ alternative approaches and multiple representations— including pictures and concrete materials—as part of explanations and answers. Teachers rely on relevant contexts to engage their students’ interest and use questions to stimulate thinking and to create language-rich mathematics classrooms. 118

NCTM Standards Process Standards Content Standards Problem Solving Reasoning and Proof Communication Connections Representations Number Measurement Geometry Algebra Data 121

123
122 All the standards rolled up into one: Problem Solving: What is this? What’s that white thing? Communication: Tell the person sitting next to you. Reasoning: How do you know? Connections: A real rip-off ad. Representations: A picture

124
But look at what else this example shows us: Consider how we teach reading: JANE WENT TO THE STORE. Who went to the store? Where did Jane go? Why do you think Jane went to the store? Do you think it made sense for Jane to go to the store? 123

125
Now consider mathematics: TAKE OUT YOUR HOMEWORK. - # # #3 185 (No why? No how do you know? No who has a different answer?) 124

126
125 Strategy #1 Adapt from what we know about reading (incorporate literal, inferential, and evaluative comprehension to develop stronger neural connections)

127
The bottom line Good math teaching BEGINS with an answer (often a wrong answer) 126

128
127 Number from 1 to 6 1. What is 6 x 7? 2. What number is 1000 less than 18,294? 3. About how much is 32¢ and 29¢? 4. What is 1/10 of 450? 5. Draw a picture of 1 2/3 6. About how much do I weight in kg?

129
128 Good morning Boys and Girls Number from 1 to 5 1. What is the value of 3P – 5R when P=4 and R=-6? 2. What are the slope and y-intercept of the line represented by y = -5x + 10? 3. If 140 pounds of rice cost $240, how much rice can you buy for $360? 4. Solve for M: 17M – 12 = 4M About how much do I weight in kg?

130
129 Strategy #2 Incorporate on-going cumulative review into instruction every day.

131
130 Implementing Strategy #2 Almost no one masters something new after one or two lessons and one or two homework assignments. That is why one of the most effective strategies for fostering mastery and retention of critical skills is daily, cumulative review at the beginning of every lesson.

132
131 On the way to school: A term of the day A picture of the day An estimate of the day A skill of the day A graph of the day A word problem of the day

133
What about homework? Typical practice: , 34, 37 odd even Alternative practices: –Max of 10 –Answers on board/answer sheets and self-check –Check your partner –Which 2 need more attention and why –Document camera to save time 132

134
Great Take a deep breath! 133

135
Tell me what you see. 2 1/4 134

136
Tell me what you see. 135

137
Tell the person sitting next to you five things you see. 136

138
137 Tell me what you see.

139
138 Strategy #3 Create a language rich classroom. (Vocabulary, terms, answers, explanations)

140
139 Implementing Strategy #3 Like all languages, mathematics must be encountered orally and in writing. Like all vocabulary, mathematical terms must be used again and again in context and linked to more familiar words until they become internalized. Sum = both Difference – bigger than Area = covering Quotient = sharing Perimeter = border Mg = grain of sand Cos = bucket Cubic = S Circumference = a belt Surface area = skin Tan = sin/cos = y/x for all points on the unit circle

141
Ready, set, picture….. “three quarters” 140

142
Ready, set, picture….. The radius and the tangent at point S on a circle with center at point O 141

143
142 Ready, set, picture….. y = sin x y = 2 sin x y = sin (2x)

144
143 Strategy #4 Draw pictures/ Create mental images/ Foster visualization

145
144 Thinking vs. Math 24.The number of boys attending Fairfield High School is twice the number of girls. If 1/6 of the boys and 1/4 of the girls are in the school band, what fraction of the student are in the school band? 5/36 7/36 2/9 7/24 5/12

146
The “right” way: Let B = the number of boys Let G = the number of girls So: 2G = B Find: 1/6 B + 1/4 G = 1/6 (2G) + 1/4 G) B + G 2G + G = (2/6 G + 1/4 G)/3G = 7/12 G / 3G = 7/36 145

147
The Stanley Kaplan Approach BoysGirls 2 : 1 1/6 1/4 Try: 100 students – 2 to 1 – no Try: 90 students – 60 and 30, 6 and oops Try: 6ths & 4ths – 24 and 48 – out of 72 14/72 = 7/36 146

148
Or even better for some: K kids, ergo boys = 2/3K and girls = 1/3K Band = 1/6 (2/3K) + 1/4 (1/3K) = (1/9 + 1/12) K or 7/36 K OR 2/3 1/3 Boys Girls 147 1/6 of 2/3 1/4 of 1/3

149
So how do we get there? 148

150
Critical next steps Build familiarity with the CCSSM Course by course discussions Professional collaboration Crosswalks The mathematical practices Think 15% per year Focus on instructional quality/opportunity to learn 149

151
Rollout Timeline, hopefully : A year of comprehensive planning (clarifying what needs to be done when) : A year of study (analyzing crosswalks, curricular implications, policy shifts) : A year of piloting and collaborative discussions : A year of curriculum and policy implementation and an assessment moratorium : A year of accountable implementation 150

152
So what can we do? Potential structures for professional sharing: Structured and focused department meetings Before school breakfast sessions Common planning time – by grade and by department Pizza and beer/wine after school sessions Released time 1 p.m. to 4 p.m. sessions Hiring substitutes to release teachers for classroom visits Coach or principal teaching one or more classes to free up teacher to visit colleagues After school sessions with teacher who visited, teacher who was visited and the principal and/or coach to debrief Summer workshops Department seminars 151

153
So what can we do? Potential Strategies for developing professional learning communities: Classroom visits – one teacher visits a colleague and the they debrief Demonstration classes by teachers or coaches with follow-up debriefing Co-teaching opportunities with one class or by joining two classes for a period Common readings and CCSSM sections assigned, with a discussion focus on: –To what degree are we already addressing the issue or issues raised in this article? –In what ways are we not addressing all or part of this issue? –What are the reasons that we are not addressing this issue? –What steps can we take to make improvements and narrow the gap between what we are currently doing and what we should be doing? 152

154
So what can we do (cont.)? Technology demonstrations (graphing calculators, SMART boards, document readers, etc.) Collaborative lesson development Video analysis of lessons Analysis of student work Development and review of common finals and unit assessments What’s the data tell us sessions based on state and local assessments What’s not working sessions Principal expectations for collaboration are clear and tangibly supported Policy analysis discussions, e.g. grading, placement, requirements, promotion, grouping practices, course options, etc. 153

155
In other words Reduce the professional isolation Enhance the transparency of our work To raise the quality of what we do 154

156
Discussion Question Which of these CAN’T you do and why? 155

157
So…. While we acknowledge the range and depth of the problems we face, It should be comforting to see the availability and potential of solutions to these problems…. Now go forth and start shifting YOUR school’s high school mathematics program to better serve our students, our society and our future. 156
