Q & A
What is mathematical representation?
-Mathematical representation refers to the processes and products of capturing mathematical concepts or relationships in various forms, such as symbols, diagrams, or physical objects.
How does NCTM define representation?
-The National Council of Teachers of Mathematics (NCTM) defines representation as a process and product, indicating the capturing of mathematical concepts in different forms.
What are some examples of mathematical representations?
-Examples include using physical objects, diagrams, verbal language, written symbols, mathematical expressions, and equations.
According to Jitendra, what does representation encompass?
-According to Jitendra, representation encompasses configurations of manipulative materials, physical objects, images, diagrams, real-life situations, spoken language, or written symbols.
What is Golden's definition of mathematical representation?
-Golden defines mathematical representation as a visible or tangible production, such as line diagrams, numbers, graphs, physical models, written words, mathematical expressions, and equations.
What operational definition of mathematical representation was provided?
-The operational definition provided states that mathematical representation is the presentation of mathematical concepts in visible and tangible forms, including physical objects, diagrams, numbers, graphs, and mathematical expressions.
What are some methods to represent numbers mathematically?
-Numbers can be represented using various numeral systems such as Roman numerals or Arabic numerals, as well as through physical objects. For instance, the number 5 can be represented with five sticks.
What indicators were used to measure mathematical representation?
-Three indicators were used: (1) creating representations to communicate mathematical ideas, (2) applying mathematical representations to solve problems, and (3) using representations to model physical, social, and mathematical phenomena.
What activities can enhance mathematical representation skills?
-Activities that involve creating and manipulating different forms of representations can enhance mathematical representation skills, along with discussions and problem-solving tasks.
What should participants do after the session?
-Participants are encouraged to send in any questions they may have for discussion and to read the references provided to further their understanding of mathematical representation.
