Mathematics As a Second Language
God wrote the universe in the language of mathematics Galileo
Mathematics is truly a second language for all children. It is a complex language. It has its own alphabet, symbols, vocabulary, syntax, and grammar. It has its own structure. Numeric and operational symbols are its alphabet; number and symbol combinations are its words; and equations and mathematical expressions are the sentences of this language.
Acquiring proficiency in mathematics and solving mathematics word problems means learning this language well. For all grade levels
This workshop will cover:
Center for Teaching/Learning of Mathematics
CT/LM has programs and materials to assist teachers, parents, therapists, and diagnosticians to help children and adults with their learning difficulties in mathematics. We conduct regular workshops, seminars,and lectureson topics such as:
- Building a Mathematics Vocabulary
- Use of Syntax and Voice in Mathematics Language
- The Role of Language in Developing Conceptual Schemas
- Developing Translation Ability—Solving Word Problems
- The Role of Questions in Acquiring Mathematics Language
- Understanding Instructions to Mathematics Problems
- Teaching Mathematics Language
- Thenature of mathematics content and learning,
- The learner characteristics and skill sets,
- The teaching models those are effective for particular content and skills for particular groups of children.
- a) Symbols—in both reading and mathematics, children must recognize and comprehend the message being conveyed by the words or numerical and operation symbols;
- b) Vocabulary—for children to understand the symbols in both reading and mathematics, it is necessary to learn the vocabulary associated with each area. In effect, they must develop the language whether it is mathematical language or native language;
- c) Skill hierarchy—both reading and mathematics contain hierarchies of skills. Children show progress to attain mastery in these skills through several intermediate stages: intuitive, concrete, pictorial, abstract, applications, and communication (Sharma, 1979a);
- d) Readiness for learning—both reading and computation skills have prerequisite skills. Readiness for certain mathematical skills can be viewed from at least four theoretical points of view—cognitive, neurological, instructional, and ontological;
- e) Sensory processes—since children must rely on input in both mathematics and reading, it is important that one pays attention to the modalities (visual, auditory, and tactile) of information processing;
- f) Decoding—decoding and encoding processes are crucial to a child’s success in mathematics and reading. When children encounter an event involving numerical quantities or spatial information, they must be able to express (decode) these numerical and spatial relationships in symbolic notations; and
- g) Comprehension—as in reading, the four factors—word recognition, comprehension, rate and accuracy—are important, similarly, in mathematics, the four factors of basic facts – recognition, comprehension, rate and accuracy – constitute good computational ability.
- MATHEMATICS IDEAS HAVE THREE MAIN COMPONENTS (in this order):
- Linguistic component,
- Conceptual component, and
- Procedural component
- VOCABULARY
- SYNTAX
- TWO-WAY TRANSLATION
- Vocabulary{words, terms, and phrases, such as: multiplication, product, sum, quotients, least common denominator, rational number, proportional reasoning, etc.} and Symbols {= -, x, +, %, ( ), etc.}
- Syntax: The order of wordsor order of operationsused in mathematical expressions (e.g., difference of a and b (a –b) is not the same as difference of b and a (b – a)).
- Translation: To conceptualize mathematics ideas and solving word problems, students need competence in “two-way” translation: English to Mathematics as well as Mathematics to English. In learning and teaching mathematics we are constantly moving from one language to the other. For example: If we have: 17 − 9 = ? How can we write this as an English sentence? Teacher should generate one or two statements and then, ask students to write more statements with their partners.
- Language Difficulties, Dyslexia, and Mathematics Learning
- Dyslexia
- The dyslexic may have a problem with numbers and calculations involving adding, subtracting, and timetables.
- He may be confused by similar—looking mathematical signs: + and ×; –, :, ¸and = ; < (less than) and > (greater than).
- He may not grasp that the words ‘difference’, ‘reduce’ ‘take away’ and ‘minus’ all suggest ‘subtraction’.
- He may understand the term ‘adding’, yet be confused if asked to ‘find the total or sum’.
- The dyslexic may reverse numbers, and read or write 17 for 71, or 2/3 as 3/2.
- He may transpose numbers i.e., 752 to 572 or some other arrangement of digits.
- He may have a difficulty with mental arithmetic.
- He may have a problem with telling the time.
- Mathematics problems related to and originating from language processing difficulties,
- Mathematics problems that have the same basis as the reading problems because of the underlying learning mechanism, such as sequencing, visual-perceptual integration, working memory, organization, spatial orientation, etc.
- Mathematics problems that originate from the combination of language and reasoning deficits.
- Lexical Entries (Naming, Labeling and Language Containers)
- Mathematics Disability Subtypes
- First, we do not have any agreement about what constitutes the core skills in mathematics. There is no one particular skill that is at the core of every mathematical operation. Despite a general agreement on the wider contours of mathematics concepts to be mastered by children in elementary school, there is no agreement on the specific nature and type of skills, the level of mastery and fluency, and the timetable for achieving the skills for mathematics achievement.
- Second, because of the cumulative nature of mathematics, we are not able to identify the core skills. Unlike the key basic processes that underlie reading achievement, mathematical achievement is cumulative and comprehensive throughout and beyond the elementary school years, with quantitative and qualitative changes occurring within and across grade levels. Almost 30% of curriculum material at each grade is new or expanded substantially.
- Third, after acquisition of the key skill (number conceptualization), learning and applying mathematics depend on a diverse set of skills. These skills are spread over several different domains of functions.
- Mathematics Problems Related to Reading
- Difficulty with the vocabulary and terminology of mathematics, understanding directions and explanations or translating word problems,
- Difficulty with irrelevant information included in the word problem or out of sequence information,
- Trouble learning or recalling concepts, definitions and meanings of abstract terms,
- Difficulty reading texts to direct their own learning and communicating mathematics, including asking and answering questions,
- Lack of information concerning mathematical facts due to the failure of the child to make normal school progress (since, the child with reading problem may be taken out of the mainstream class or placed in special classes where the emphasis is on reading progress, the child may not get enough instruction in mathematics and therefore has limited exposure to mathematics), and
- Emotional blocking due originally to reading disability but eventually extended to mathematics.
- Role of Instructions in Mathematics Learning and Problem Solving
- The mastery of mathematics language in order to be able to read, comprehend and conceptualize the problem (The use of language is to create ideas, receive and communicate ideas);
- The presence of and facility in recognizing, and relating the language to appropriate conceptual schemas(arithmetical, algebraical, geometrical—definitions, diagrams, formulas, and relationship); and,
- The ability and facility in executing appropriate procedures(involved explicitly and implicitly in the language of the instructions and in the problem) in an effective and efficient manner.
- What is a Mathematical Instruction?
- Identifiers (i.e., The shape in the diagram is called…; the digit in the hundered’s place in the number 45,678.12 is ___. );
- Verbs (i.e., multiply the fractions: ⅘ and½; differentiate the function …;reciprocate the fraction …;find the square root of ….; locate the point √2 on number line; reduce the fraction …. to the lowest term; it implies that 2 is an even number; deduce that every square is a rectangle; prove that 8 is not a prime number; show that 7 is a prime number; determine the nature and number of factors of square numbers; etc.);
- Concepts/nouns (i.e., place-value, arithmetic sequnece, multiplication, ratio and proportion, exponential function, addition, etc.);
- Qualifiers/adjectives(i.e., 123 is a 3-digit number; 24, and 2n are even numbers, where nis an integer; √(n)is an irrational number, for any non-square, positive, whole number number; the equation: y = mx + bis called the slope-intercept form of a linear equation; the least common multiple of 8 and 12 is 24; the greatest common factor of 8 and 12 is 4; y = x2is a continuous function for all x; etc.);
- Objects/noun (i.e., triangle, quadratic formula, parabola, focus of a conic section, square-root symbol, etc.);
- Outcome of operations (i.e., sum, difference, product, quotient, ratio, differential coefficient, square root, etc.);
- Cognitive and mathematics thinking functions (i.e., compare, analyze, relate, recognize the pattern, extend the pattern, make a conjecture, conclude, arrange, organize, focus, visualize, manipulate the information in the mind’s eye, spatial orientation/space organization, logical connectives: all integers…, every squareis…; if and then, if and only if, etc.).
- Why are instructions such a challenge for many students?
- Types of Instructions: Explicit and Implicit
- Multiply the numbers 1.2 and 1.3,compared with the instruction: find the product of 1.2 and 1.3.
- Multiply the binomials (2a + 3)and (3a + 4) using ‘FOIL’ or distributive property of multiplication, compared with the instruction: find the quadratic expression with binomials (2a + 3) and (3a + 4) as its facotrs.
- Find the value of the function f(x) = (2x + 3)(7x + 5)for x = −3, compared with the instruction: find f(a), if f(x) = (2x + 3)(7x + 5).
- Differentiate the function: f(x) = (2x + 3)(7x + 5) at x = 2, compared to the instruction find f(a) for the function: f(x) = (2x + 3)(7x + 5).
- Differentiate the function f(x) = 2x3sin(5x) by parts, compared to the instruction find df/dx for the function: f(x) = 2x3sin(5x).
- Subtract 7 from 10, compared with find the difference of 7 and 10.
- using the long division procedure, find the quotient of 7.25 divided by .025,
- Find the product of fractions: 3½ and 2¾, or
- find the greatest common factor of numbers 6, 48, and 54.
- Fred is 63 inches tall. What else must you know to find out how much he has grown in the past year?
- How much did he weigh a year ago?
- How tall will he be next year?
- How old is he this year?
- How tall was he last year?
- Role of Questioning in Understanding Mathematics Instructions
- Questions instigate language;
- Language instigates models;
- Models instigate thinking;
- Thinking instigates understanding;
- Understanding produces competent performance;
- Competent performance is the basis of long lasting high self-esteem; and
- High self-esteem contributes to motivation for learning and engagment.
- Strategies for Improving the Understanding of Instructions
- practiced arithmetic facts to the automatization level with efficient and effective strategies (arithmetic facts are best derived using decomposition/recompsotion strategies);
- know a concept in its different models(e.g., multiplication as: repeated addition, groups of, an array, and area of a rectangle);
- and have applied computational procedures in a variety of different formats(e.g., division as partial quotient, long division, and short division).
