초록
본 연구는 가상조작물-추상기호의 통합된 순차적 교수와 시간제한 활동을 사용한 교수가 수학 학습장애 위험군 학생의 연산 유창성에 미치는 효과를 알아보고자 하였다. 연구 참여자는 초등학교 3, 4학년 수학 학습장애 위험군 학생 4명이었다. 단일대상연구의 중다간헐기초선설계를 사용하여 자연수 사칙연산 유창성에 대한 중재의 효과와 표준화 산술 평가를 중재 이전과 이후에 실시하여 학습 전이 효과도 알아보았다. 연구 결과, 모든 참여자의 자연수 사칙연산 유창성이 유의미하게 향상되었고, 긍정적인 학습 전이 효과도 관찰되었다. 이러한 결과는 가상조작물-추상기호의 통합된 순차적 교수와 시간제한 활동이 수학 학습장애 위험군 학생의 연산 유창성 향상에 효과적임을 시사한다.
Abstract
This study aimed to investigate the effects of instruction utilizing virtual-abstract integrated instructional sequence and timed activities on the computational fluency of students at risk for learning disabilities in mathematics. The participants comprised four students in grades 3-4 who were identified as at risk for learning disabilities in mathematics. Employing a multiple-probe-across-participants single-case design, this study examined the effect of the intervention on four basic arithmetic fluency and near transfer effects. Additionally, a standardized assessment was administered pre- and post-intervention to evaluate far transfer effects. The results of this study demonstrated significant improvements in computational fluency across all participants, with positive near and far transfer effects observed. These findings suggest that the integration of virtual-abstract integrated instructional sequence and timed activities may be an effective instructional approach for enhancing computational fluency for students at risk for mathematics learning disabilities.
