They may attempt to explain the method to themselves and correct it if necessary. Carpenter, Corbitt, Kepner, Lindquist, and Reys, 1981. One question that warrants an immediate answer is whether students in U.S. elementary and middle schools today are becoming mathematically proficient.

(2001). See Hiebert and Carpenter, 1992, for a discussion of the ways that cognitive science informs mathematics education on the nature of conceptual understanding. (1999). Ladson-Billings, G. (1999). But on a multistep addition and subtraction word problem involving similar numbers, only 33% of fourth graders gave a correct answer (although 76% of eighth graders did). In general, U.S. boys have more positive attitudes toward mathematics than U.S. girls do, even though differences in achievement between boys and girls are, in general, not as pronounced today as they were some decades ago.64 Girls attitudes toward mathematics also decline more sharply through the grades than those of boys.65 Differences in mathematics achievement remain larger across groups that differ in such factors as race, ethnicity, and social class, but differences in attitudes toward mathematics across these groups are not clearly associated with achievement differences.66, The complex relationship between attitudes and achievement is well illustrated in recent international studies. The relation between conceptual and procedural knowledge in learning mathematics: A review. mathematics. Similarly, the capacity to think logically about the relationships among concepts and situations and to reason adaptively applies to every domain of mathematics, not just number, as does the notion of a productive disposition. WHAT MATH PROFICIENCY IS AND HOW TO ASSESS IT 63 In 2000, the Silicon Valley Mathematics Assessment Collaborative gave two tests to a total of 16,420 third, fth, and seventh graders. Although most can compute well with whole numbers in simple contexts, many still have difficulties computing with rational numbers. . (1957). And while carrying out a solution plan, learners use their strategic competence to monitor their progress toward a solution and to generate alternative plans if the current plan seems ineffective. ), Handbook of educational psychology (pp. 1938. The more mathematical concepts they understand, the more sensible mathematics becomes. How the strands of mathematical proficiency interweave and support one another can be seen in the case of conceptual understanding and procedural fluency. [July 10, 2001]. Students who have learned only procedural skills and have little understanding of mathematics will have limited access to advanced schooling, better jobs, and other opportunities. (Eds.). Another reduction of the number of tricycles by 4 gives 28 bikes, 8 tricycles, and the 80 wheels needed. Mathematical proficiency, as we see it, has five components, or strands: conceptual understandingcomprehension of mathematical concepts, operations, and relations, procedural fluencyskill in carrying out procedures flexibly, accurately, efficiently, and appropriately, strategic competenceability to formulate, represent, and solve mathematical problems, adaptive reasoningcapacity for logical thought, reflection, explanation, and justification.

Becoming strategically competent involves an avoidance of number grabbing methods (in which the student selects numbers and prepares to perform arithmetic operations on them)23 in favor of methods that generate problem models (in which the student constructs a mental model of the variables and relations described in the problem). [July 10, 2001]. It prompts teachers to examine the extent to which their students have attained. SOURCE: 1996 NAEP assessment. Only 61% of 13-year-olds chose the right answer, which again is considerably lower than the percentage of students who can actually compute the result.

This level of performance is especially striking because this kind of reasoning does not require procedural fluency plus additional proficiency. Novice problem solvers are inclined to notice similarities in surface features of problems, such as the characters or scenarios described in the problem. Journal for Research in Mathematics Education 21, 180206. The four Australian proficiency strands are: Understanding, fluencyproblem solving, , and reasoning (Australian Curriculum Assessment and Reporting Authority, n.d.). Then the keywords how much and 5 gallons suggest that 5 should be multiplied by the result, yielding $5.40.

Introduction to psychology (2nd ed.). The most important observation we make here, one stressed throughout this report, is that the five strands are interwoven and interdependent in the development of profi ciency in mathematics (see Box 41). Researchers have shown clear disconnections between students street mathematics and school mathematics, implying that skills learned without understanding are learned as isolated bits of knowledge. Developmental Psychology, 35, 127145. The skill in carrying out procedures flexibly, accurately, efficiently, and appropriately. New York: Macmillan. In a common superficial method for representing this problem, students focus on the numbers in the problem and use so-called keywords to cue appropriate arithmetic operations.24 For example, the quantities $1.83 and 5 cents are followed by the keyword less, suggesting that the student should subtract 5 cents from $1.13 to get $1.08. Learning is not an all-or-none phenomenon, and as it proceeds, each strand of mathematical proficiency should be developed in synchrony with the others. The NAEP long-term trend mathematics assessment is more heavily weighted [than the main NAEP] toward students knowledge of basic facts and the ability to carry out numerical algorithms using paper and pencil, exhibit knowledge of basic measurement formulas as they are applied in geometric settings, and complete questions reflecting the direct application of mathematics to daily-living skills (such as those related to time and money) (Campbell, Voelkl, and Donahue, 2000, p. 50). (1996). Washington, DC: Author. Students also need to be able to apply procedures flexibly. We describe what students are capable of, what the big obstacles are for them, and what knowledge and intuition they have that might be helpful in designing effective learning experiences. Dweck, C. (1986). Conceptual understanding refers to an integrated and functional grasp of mathematical ideas. Schools need to prepare students to acquire new skills and knowledge and to adapt their knowledge to solve new problems. 117148).

In the domain of number, procedural fluency is especially needed to support conceptual understanding of place value and the meanings of rational numbers. This bottom- Our analyses of the mathematics to be learned, our reading of the research in cognitive psychology and mathematics education, our experience as learners and teachers of mathematics, and our judgment as to the mathematical knowledge, understanding, and skill people need today have led us to adopt a. composite, comprehensive view of successful mathematics learning. (3) Strategic Competence (Applying): Being able to formulate problems mathematically and to devise strategies for solving them using concepts and procedures appropriately. For a review of the literature on race, ethnicity, social class, and language in mathematics, see Secada, 1992. All reality is composed of atoms in a void. inclination to see mathematics as sensible, useful, and worthwhile, (1979). Consider, for instance, the multiplication of multidigit whole numbers. A more sophisticated, algebraic approach would be to let b be the number of bikes and t the number of tricycles. Results from the seventh mathematics assessment of the National Assessment of Educational Progress. The learning gap: Why our schools are failing and what we can learn from Japanese and Chinese education. Effective teaching of mathematics builds fluency with procedures on a foundation of conceptual understanding so that students, over time, become skillful in using procedures flexibly as they solve contextual and mathematical problems. For example, finding the product of 567 and 46 is a routine problem for most adults because they know what to do and how to do it. Available: http://books.nap.edu/catalog/1580.html.

In general, the performance of 13-year-olds over the past 25 years tells the following story: Given traditional curricula and methods of instruction, students develop proficiency among the five strands in a very uneven way. (1992a). It is clear that for many students that connection is not being made. The 1990 and 1992 NAEP assessments indicated that the few gender differences in mathematics performance that did appear favored male students at grade 12 but not before. 623660). Ready to take your reading offline? Students with conceptual understanding know more than isolated facts and methods. Procedural fluency refers to knowledge of procedures, knowledge of when and how to use them appropriately, and skill in performing them flexibly, accurately, and efficiently. (2000).

Math Learning Study Committee, Center for Education, Division of Behavioral and Social Sciences and Education. Learners draw on their strategic competence to formulate and represent a problem, using heuristic approaches that may provide a solution strategy, but adaptive reasoning must take over when. Learning to understand arithmetic. Adaptive reasoning refers to the capacity to think logically about the relationships among concepts and situations. Students often understand before they can verbalize that understanding.6. (1988). In J.Hiebert (Ed. [July 10, 2001]. Available: http://books.nap.edu/catalog/1199.html. In this report, we present a much broader view of elementary and middle school mathematics. The Five Strands of Mathematics Proficiency DEVELOPING MATHEMATICIANS National Research Council. (5) Model with . (1993). (1976). In B.Grevholm & G.Hanna (Eds. It is not as critical as it once was, for example, that students develop speed or efficiency in calculating with large numbers by hand, and there appears to be little value in drilling students to achieve such a goal. Beaton, A.E., Mullis, I.V.S., Martin, M.O., Gonzalez, E.J., Kelly, D.L., & Smith, T.A. 4572). One conclusion that can be drawn is that by age 13 many students have not fully developed procedural fluency. On the 23 problem-solving tasks given as part of the 1996 NAEP in which students had to construct an extended response, the incidence of satisfactory or better responses was less than 10% on about half of the tasks. ), Developing mathematical reasoning in grades K-12 (1999 Yearbook of the National Council of Teachers of Mathematics, pp. 1724). A cognitive approach to meaningful mathematics instruction: Testing a local theory using decimal numbers. It is still reasonable, however, to talk about a first grader as being proficient with single-digit addition, as long as the students thinking in that realm incorporates all five strands of proficiency. American Psychologist, 50(1), 2437. Chicago: University of Chicago Press. But pitting skill against understanding creates a false dichotomy.12 As we noted earlier, the two are interwoven.

Do you enjoy reading reports from the Academies online for free? Also, students should be able to perform such operations as finding the sum of 199 and 67 or the product of 4 and 26 by using quick mental strategies rather than relying on paper and pencil.

They are most proficient in aspects of procedural fluency and less proficient in conceptual understanding, strategic competence, adaptive reasoning, and productive disposition. Then they need to formulate the problem so that they can use mathematics to solve it. 117147). National Assessment Governing Board. Washington, DC: National Academy Press. Students need to see that procedures can be developed that will solve entire classes of problems, not just individual problems. Because facts and methods learned with understanding are connected, they are easier to remember and use, and they can be reconstructed when forgotten.5 If students understand a method, they are unlikely to remember it incorrectly. This could allow us to address unequal acquisition of mathematical proficiency in school. This. ), Handbook of research on mathematics teaching and learning (pp. Support productive struggle in learning mathematics. Paper prepared for the Mathematics Learning Study Committee, National Research Council, Washington, DC. Still others might ask how the layout of the cafeteria might be improved. It is counterproductive for students to believe that there is some mysterious math gene that determines their success in mathematics. More expert problem solvers focus more on the structural relationships within problems, relationships that provide the clues for how problems might be solved.26 For example, one problem might ask students to determine how many different stacks of five blocks can be made using red and green blocks, and another might ask how many different ways hamburgers can be ordered with or without each of the following: catsup, onions, pickles, lettuce, and tomato. Get a handle on Probability and predict what the most . They see that mathematics is both reasonable and intelligible and believe that, with appropriate effort and experience, they can learn. That situation appears to be improving, although perhaps not uniformly across, grades. Terms in this set (6) Conceptual Understanding.

Proof is a form of justification, but not all justifications are proofs. Hiebert, J., & Carpenter, T.P. In L.D.English (Ed. The attention they devote to working out results they should recall or compute easily prevents them from seeing important relationships. The best source of information about student performance in the United States is, as we noted in chapter 2, the National Assessment of Educational Progress (NAEP), a regular assessment of students knowledge and skills in the school subjects. Strategic competence comes into play at every step in developing procedural fluency in computation. In the Academy of MATH, component skills of mathematics have been broken down and individually addressed, with students trained along a developmental sequence. 8.

Five strands of mathematical proficiency From NRC (2001) Adding it up: Helping children learn mathematics Conceptual understanding: comprehension of mathematical concepts, operations, and relations Procedural fluency: skill in carrying out procedures flexibly, accurately, efficiently, and appropriately Strategic competence: ability to formulate, represent, and solve mathematical problems (Ed.). Because the strands interact and boost each other, students who have opportunities to develop all strands of proficiency are more likely to become truly competent with each. When children are first learning about even and odd, they may know one or two of these interpretations.53 But at an older age, a deep understanding of even and odd means all four interpretations are connected and can be justified one based on the others. The teaching experiment classroom. This environment of negative expectation is strongest among minorities and women those most at riskduring the high school years when students first exercise choice in curricular goals.48. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. For discussion of learning in early childhood, see Bowman, Donovan, and Burns, 2001. Flexibility develops through the broadening of knowledge required for solving nonroutine problems rather than just routine problems. For example, it is not sufficient for students to do only practice problems on adding fractions after the procedure has been developed. The contents of a given cluster may be summarized by a short sentence or phrase like properties of multiplication, which is sufficient for use in many situations. Part of developing strategic competence involves learning to replace by more concise and efficient procedures those cumbersome procedures that might at first have been helpful in understanding the operation. Students should not be thought of as having proficiency when one or more strands are undeveloped. In short, they need to be mathematically proficient. Journal of Experimental Psychology: General, 124, 8397. (1997). Mathematics framework for the 1996 and 2000 National Assessment of Educational Progress. If students learn to subtract with understanding, they rarely make, Box 42 A common error in multidigit subtraction. Reston, VA: National Council of Teachers of Mathematics. Many conceptions of mathematical reasoning have been confined to formal proof and other forms of deductive reasoning. There is reason to believe that the conditions apply more generally. Justification and proof are a hallmark of formal mathematics, often seen as the province of older students. How people learn: Bridging research and practice. Ansell, E., & Doerr, H.M. (2000). Often a solution strategy will require fluent use of procedures for calculation, measurement, or display, but adaptive reasoning should be used to determine whether the procedure is appropriate.

Interestingly, very young children use a variety of strategies to solve problems and will tend to select strategies that are well suited to particular problems.29 They thereby show the rudiments of adaptive reasoning, the next strand to be discussed. 5. Classroom Data Analysis with the Five Strands of Mathematical Proficiency Randall E. Groth Published 10 April 2017 Education The Clearing House: A Journal of Educational Strategies, Issues and Ideas ABSTRACT Qualitative classroom data from video recordings and students' written work can play important roles in improving mathematics instruction. These differences were only partly explained by the historical tendency of male students to take more high school mathematics courses than female students do, since that gap had largely closed by 1992. The results were only slightly better at grade 12. 132136. (5) Productive disposition Effective teaching of mathematics uses purposeful questions to assess and advance students reasoning and sense making about important mathematical ideas and relationships. The 1990 populations of Town A and Town B were 8,000 and 9,000, respectively. The teacher of mathematics plays a critical role in encouraging students to maintain positive attitudes toward mathematics. Race, ethnicity, SES, gender, and language proficiency trends in mathematics achievement: An update. Instruction on derived facts strategies in addition and subtraction. 2138). As students learn how to carry out an operation such as two-digit subtraction (for example, 8659), they typically progress from conceptually transparent and effortful procedures to compact and more efficient ones (as discussed in detail in chapter 6). San Jose, CA: San Jose State University. ), Results from the fourth mathematics assessment of the National Assessment of Educational Progress (pp. Every important mathematical idea can be understood at many levels and in many ways. On the other hand, once students have learned procedures without understanding, it can be difficult to get them to engage in activities to help them understand the reasons underlying the procedure.13 In an experimental study, fifth-grade students who first received instruction on procedures for calculating area and perimeter followed by instruction on understanding those procedures did not perform as well as students who received instruction focused only on understanding.14. As such, a task-analytic approach is appropriate for math instruction (Gersten et al., 2009; National Mathematics Advisory Panel, 2008).

In contrast, when students are seldom given challenging mathematical problems to solve, they come to expect that memorizing rather than sense making paves the road to learning mathematics,41 and they begin to lose confidence in themselves as learners. Problem solving in context(s). Wearne, D., & Hiebert, J. Research with older students and adults suggests that a phenomenon termed stereotype threat might account for much of the observed differences in mathematics performance between ethnic groups and between male and female students.49 In this phenomenon, good students who care about their performance in mathematics and who belong to groups stereotyped as being poor at mathematics perform poorly on difficult mathematics problems under conditions in which they feel pressure to conform to the stereotype. (1997b). We conclude that during the past 25 years mathematics instruction in U.S. schools has not sufficiently developed mathematical proficiency in the sense we have defined it.
