Abstract

This paper observed the effect of CAS calculator usage while studying algebra on the achievement of low-achievement students. Participants were composed of 70 low-achievement tenth grade students from a high school located in a metropolitan city. That had never used a mathematics educational calculator before. Target participants were divided into two groups: an experiment group that studied activity papers with the aid of a CAS calculator, and a control group that studied the same activity papers using only paper-and-pencil. The content of the activity papers for the two groups was the same, but the structure differed. Content consisted of numbers and operations, equations and inequalities(character and expressions), and functions. Students in the experiment group exhibited matacognition learning using a CAS calculator. The two groups completed mathematics achievement tests both before and after the activity papers. Therefore, ANCOVA analysis results showed that compared to the pretest, results of the experiment group improved considerably more than the control group.

본 논문은 수학수업에서 점점 소외되고 있는 수학학습부진아가 대수학습에서 학업성취도를 신장시키기 위해 좀 더 나은 효과를 얻을 수 있는 방법을 모색하고자 하였다. 이를 위해 수학학습부진아를 선정하여 두 집단으로 나누었다. 한 집단은 처치집단으로 CAS 계산기를 사용하여 활동지를 학습하고, 다른 집단은 통제집단으로 지필을 사용하여 활동지를 학습하였다. 각 집단은 활동지를 통해서 메타인지 활동을 하였다. 수업 전과 후에 두 집단 모두 지필로 수학학업성취도를 실시하여 비교 분석한 결과, 처치집단이 통제집단보다 여러 가지 측면에서 더 나은 효과를 나타내는 것을 확인하였다.
