NCCTM Central Region Conference - NC Mathematics
2012 NCCTM Central Region Conference Robin Barbour [email protected] Hong Kong / US Data • Hong Kong had the highest scores in the most recent TIMMS. • Hong Kong students were taught 45% of objectives tested. • Hong Kong students outperformed US students on US content that they were not taught. • US students ranked near the bottom. • US students ‘covered’ 80% of TIMMS content. • US students were outperformed by students not taught the same objectives. Lessons Learned • Mile wide and inch deep does not work. • The task ahead is not so much about how many specific topics are taught; rather, it is more about ways of thinking. • To change students’ ways of thinking, we must change how we teach. Lesson Comparison Japan and United States The emphasis on skill acquisi1on is The emphasis on understanding is evident in the steps most common in U.S. evident in the steps of a typical Japanese classrooms lesson • Teacher instructs students in concept or skill • Teacher poses a thought provoking problem • Teacher solves example problems with class • Students and teachers explore the problem • Students prac8ce on their own while teacher assists individual students • Various students present ideas or solu8ons to the class • Teacher summarizes the class solu8ons • Students solve similar problems 4 Types of Math Problems Presented How Teachers Implemented Making Connections Math Problems Points to Ponder • What is the goal of teaching mathematics? What am I really trying to accomplish in my classroom? • Does my lesson plan emphasize mathematical thinking and process, or is the goal to demonstrate procedures and obtain right answers? Points to Ponder • Is there a place in my classroom for lecture? Do I balance my teaching strategies? • Do I help my students find connections between big ideas in mathematics? • What type of seatwork do my students do? • What kinds of questions do I ask in my classes? Points to Ponder • Do I tend to encourage students to find multiple ways to solve the same problem? • What do I do when students get frustrated or confused? • What do I do when a student makes a mistake? Hoffman, Lauren R. and Brahier, Daniel J., Improving the Planning and Teaching of Mathematics by Reflecting on Research. Mathematics Teaching in the Middle School. VOL. 13, NO. 76, March 2008 www.corestandards.org Standards for 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 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 S T U D E N T E N G A G E M E N T Mathematics Claims The Smarter Balanced Assessment Consortium has released a document outlining four claims about what mathematically proficient students can do. The claims are a synthesis of the Standards for Mathematical Practice, and form the guiding principles to be used in creating assessments. Mathematics Claim #1 Students can explain and apply mathematical concepts and carry out mathematical procedures with precision and fluency. Mathematics Claim #2 Students can frame and solve a range of complex problems in pure and applied mathematics. Mathematics Claim #3 Students can clearly and precisely construct viable arguments to support their own reasoning and to critique the reasoning of others. Mathematics Claim #4 Students can analyze complex, real-world scenarios and can use mathematical models to interpret and solve problems. Which of the following represents 2/5? a. b. c. d. For numbers 1a – 1d, state whether or not each figure has 2/5 of its whole shaded. 1a. ο Yes ο No ο Yes ο No 1c. ο Yes ο No 1d. ο Yes ο No 1b. Scoring Rubric Responses to this item will receive 0 – 2 points, based upon the following: 2 points: YNYN 1 point: YNNN, YYNN, YYYN 0 point: YYYY, YNNY, NNNN, NNYY, NYYN, NYNN, NYYY, NYNY, NNYN, NNNY, YYNY, YNYY For further information… Smarter Balanced Assessment Consortium http://www.k12.wa.us/smarter/ K – 8 Domains" Domains K 1 2 3 4 5 6 7 8 Counting and Cardinality Operations and Algebraic Thinking Number and Operations in Base Ten Measurement and Data Geometry Number and Operations - Fractions Ratios and Proportional Relationships The Number System Expressions and Equations Statistics and Probability Functions 3/1/12 • page 27 Standards" High School Standards Notation Perform operations on matrices and use matrices in applications. 6. (+) Use matrices to represent and manipulate data, e.g., to represent payoffs of incidence relationship in a network. 11. Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y =g(x intersect are the solutions of the equations f(x) = g(x); Bind the solutions approximately, e.g., using technology to graph the functions, make tables of values, or Bind successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.★ High School Themes • • • • • • Number and Quantity Algebra Functions Modeling Geometry Statistics and Probability Unpacked Content 3/1/12 • page 31 www.ncdpi.wikispaces.net 3/1/12 32 Four Teacher-Friendly Postulates for Thriving In a Sea of Change Steve Leinwand 1. We are being asked to teach in distinctly different ways from how we were taught. 2. The traditional curriculum was designed to meet societal needs that no longer exist. 3. It is unreasonable to ask a professional to change much more than 10 percent a year, it is unprofessional to change by much less than 10 percent a year. 4. If you don’t feel inadequate you are probably not doing the job.
