A Study on Understanding and Application Ability of Eleventh Graders for Basic Properties of Operations with Real Numbers

실수 연산의 기본 성질에 대한 고등학교 2학년 학생들의 이해와 적용 능력 분석

The ability of understanding the number and number systems, grasping the properties of number systems, and manipulating number systems is the foundation to understand algebra. It is useful to deepen students' mathematical understanding of number systems and operations. The authentic understanding of numbers and operations can make it possible for the students to manipulate algebraic symbols, to represent relationship among sets of numbers, and to use variables to investigate the properties of sets of numbers. The high school students need to understand the number systems from more abstract perspective. The purpose of this study is to study on understanding and application ability of eleventh graders of basic properties of operations with real numbers.
