Abstract

Regarding the formula for measuring the area of a circle, the Archimedes' constant is generally written in front of the square of radius length, but there were a few cases where the Archimedes' constant was written after that in Germany and France. In this study, two things are studied: First, how many students are writing the Archimedes' constant after that? Second, what do the students think about the written order of characters in the formula for measuring the area of a circle? In the online survey of 201 people aged 14 to 21 in Korea, there was a perception of more than 86% that both are possible or only after that are possible. In this study, it is suggested that there is a difference between the general written order of characters and the natural perception of students formed through school education. In addition, students aged 14 to 16 thought more that the Archimedes' constant should be written after that, and after that age, there was a greater perception that both are possible without confusion of meaning. It can be seen that the change in students' perception has emerged through school education on natural mathematical written order of characters after middle school courses. From this point of view, the most common perception can be that if there is no confusion in meaning, then both expressions are possible.

원의 넓이를 구하는 공식을 보면, 일반적으로 원주율이 반지름의 길이의 제곱의 앞에 쓰여 지지만 독일과 프랑스에서 원주율이 뒤에 쓰여 진 경우가 있었다. 본 연구에서는 두 가지를 연구 한다: 첫째, 원주율을 뒤에 쓰는 학생이 얼마나 있는가? 둘째, 학생들이 원의 넓이를 구하는 공식에서 문자 표기 순서에 대해 어떻게 인식하는가? 국내의 만 14세에서 만 21세까지의 사람들 중 임의 추출한 201명에 대한 온라인 설문 조사 결과 둘 다 가능하다 또는 뒤에만 가능하다는 인식이 86% 이상 있었다. 본 연구에는 원의 넓이에 대한 일반적인 문자 표기 순서와 학교 교육을 통해 자연스럽게 형성된 학생들의 인식에 차이가 있음이 보여 진다. 덧붙여 만 14세에서 만 16세까지의 학생들은 원주율을 뒤에만 써야한다는 인식이 더 강했으나 그 연령대 이후로 둘 다 가능하다는 인식의 변화가 있었다. 이러한 관점에서 의미의 혼동이 없다면, 두 표기 모두 가능하다는 것이 가장 공통적인 인식이 될 수 있다. 그러므로 교과서에는 원주율을 뒤에 쓴 표현이 추가된 방식으로 표현되어야 학생들의 이해가 더 자연스러울 것이다.
