Abstract

In this study, lessons on coordinate, percentage, and factorization in prime factors were taken with TI-73 calculator for 20 elementary school students in the 5th grade math gifted class in Pohang city. Through these lessons, the researcher examined with cases how using the calculator would influenced the lessons for the gifted students, and attempted to obtain implications on using calculators as learning tools in class. Activity sheets were made for this study and a 80-minute lesson was held three times for three weeks. In order to collect data, the class was recorded on videotape, the students were interviewed, and documents used in the class were collected. Then all the data were transcribed. Data analysis was completed through several readings of transcripts and main themes were derived by classifying, comparing, and contrasting coding. As a result of the study, the calculator played a role the tool as the mediation to communicate and the challenge their solvable tasks beyond the limitation of paper and pencil environments. But, in using the calculator, there was differences in gender between boys and girls. Above all, to enter commands into the calculator resulted in obstacles for learning process.

본 연구는 포항시에 소재하는 초등학교 5학년 수학 영재 학급 학생 20명을 대상으로 TI-73 계산기를 활용하여 좌표, 백분율, 소인수분해에 대한 수업의 질적 자료를 분석하였다. 이를 통해 계산기 활용이 영재 학생들의 학습에 어떤 영향을 미치는지 살펴보고, 계산기를 활용한 수업에 대한 시사점을 얻고자 하였다. 연구를 위해 이들 각 차시의 내용에 대해 활동지를 각각 제작하였고, 3주에 걸쳐 80분씩 3차례 수업을 진행하였다. 자료 분석을 위해 동영상 촬영, 학생과의 인터뷰, 문서 자료 등을 수집하였으며, 수집된 동영상, 녹음 자료는 녹취록을 작성하여 이를 토대로 코딩 작업을 하였다. 코드의 결합과 분해를 반복함으로써 초등 수학 영재 학생들의 계산기 사용에 대한 주제를 도출하였다. 본 연구 결과에 따르면, 의사소통을 매개하는 계산기, 지필환경의 범위를 넘어선 과제 해결을 위한 계산기, 계산기 활용에 대한 남녀의 성차 존재, 학습에 영향을 주는 계산기의 제한점이라는 네 가지 주제를 도출할 수 있었다.
