모바일 기반 수학 학습 어플리케이션 개발 및 활용 방안

Development and Application of Mobile-Based Math Learning Application

본 연구에서는 학교 수학의 내용을 담아낸 모바일 기반 수학 학습 어플리케이션을 개발하고, 이를 수학 교수․학습 상황에서 활용할 수 있는 방안을 모색하였다. 먼저, 중학교 수학의 ‘이차함수와 그래프’, ‘대푯값과 산포도’ 단원에서 조작을 통한 개념 탐구와 토론 학습이 가능하도록 어플리케이션 <중3수학교실>을 안드로이드 버전으로 수학교육전문가, 수학 교사, 컴퓨터공학 전문가, 디지털 애니메이션 감독과 협업하여 개발하였다. 이때, 예비교사의 도움을 받아 중학교 3학년 남녀 학생 4명을 대상으로 개발한 어플리케이션을 적용하여 그 활용가능성을 검증하였다. 또한, 수학 수업에 어플리케이션을 활용하는 교수․학습 지도안과 어플리케이션 활용 매뉴얼을 개발하고 중학교 3학년 1개 학급을 대상으로 사례 연구를 실시하여 그 현장 적용 가능성을 모색하였다.

The purpose of this study is to develop a mobile-based math learning application and explore its application. In order to develop a learning application, the present study included literature review on math education involving mobile learning, investigation of literature related to mathematics education conducted in a digital environment, and method of use and implementation environment of existing math learning applications by type. Based on these preliminary investigation and analysis, an android version application, ‘Mathematics Classroom for Middle School 3rd Graders’ was developed. This application can be used for learning units such as Quadratic Functions and Graphs, Representative Value, and Variance and Standard Deviation. For the unit on Quadratic Functions and Graphs, the application was constructed so that students can draw various graphs by using the graphic mode and discuss their work with other students in the chatting room. For the unit on Representative Value, the application was constructed with the mathematical concept of representative value explained through animation along with activities of grouping data acquired after playing archery games by points or arranging them according to size so that students can study when and how to use median value, mode, and average. The application for Variance and Standard Deviation unit was also constructed in a way that allowed students to study the concept of variance and standard deviation and solve the problems on their own. The results of this study can be used as teaching & learning materials customized for individual student in math classes and will provide anyone the opportunity to engage in an interesting self-directed learning of math at anytime. Developed in the format of real life study, the application will contribute to helping students develop a positive attitude about math.
