This research was to help slow learners to be motivated and to make their outcome productive, using GSP based on the mathematization theory for learning mathematics, as a way of encouraging the learner-centered approach. With 2 of the second graders in a high school, who had not yet understood trigonometric functions in their first grade period, 7 units of lesson plans were designed for the research. The results showed that first, understanding real life contexts and analyzing properties by observation, and experiment using GSP, to build the concept of trigonometric functions could be a foothold on which learner's organization and outcome from a horizontal mathematization led to vertical mathematization. Despite the delay during the level-up-stage for a while, the learners could attain the vertical mathematization stage and moreover the applicative mathematization through effective use of GSP and the interaction between the learners or a teacher and the learners. Second, using GSP was a vertical tool of connecting horizontal mathematization with vertical mathematization in forming the concept of trigonometric functions and its meaning could be understood by their verbalizing and presenting the outcomes through their active performance. Using GSP is helpful for slow learners to overcome learning difficulties, based on the instructional materials designed by Realistic Mathematics Education.

The purpose of this paper is to present a specific set of home teaching methods in hopes to prevent slow learner of the elementary mathematics. This paper deals with the number and operations, one of five topics in the elementary mathematics A survey of two hundred elementary school teachers was made to see the teacher's opinions of the role of home studying and to concretize the contents of the research topics. There were asked which is the most essential contents for the concrete loaming and which is the most difficult monad that might cause slow leaner. And those were found to be; counting, and arithmetic operations(addition and subtraction) of one or two-digit numbers and multiplication and their concepts representations and operations(addition and subtraction) of fractions. The home teaching methods are based on the situated learning about problem solving in real life situations and on the active teaming which induces children's participation in the process of teaching and learning. Those activities in teaching each contents are designed to deal with real objects and situations. Most teaching methods are presented in the order of school curriculum. To teach the concepts of numbers and the place value, useful activities using manipulative materials (Base ten blocks, Unifix, etc.) or real objects are also proposed. Natural number's operations such as addition, subtraction and multiplication are subdivided into small steps depending upon current curriculum, then for understanding of operational meaning and generalization, games and activities related to the calculation of changes are suggested. For fractions, this paper suggest 10 learning steps, say equivalent partition, fractional pattern, fractional size, relationship between the mixed fractions and the improper fraction, identifying fractions on the number line, 1 as a unit, discrete view point of fractions, comparison of fractional sizes, addition and subtraction, quantitative concepts. This research basically centers on the informal activities of kids under the real-life situation because such experiences are believed to be useful to prevent slow learner. All activities and learnings in this paper assume children's active participation and we believe that such active and informal learning would be more effective for learning transfer and generalization.

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.

최근 몇 년간 국가수준에서 학생들의 기초학력 향상을 위한 다양한 정책이 수행되었다. 2011년 초등학교 3학년 기초학습 진단평가는 학생들의 학습부진을 조기에 확인하고 그에 따른 보정 교육을 실시할 목적으로 실시되었다. 본 연구에서는 초등학교 3학년 기초학습 진단평가 기초수학의 평가 결과를 토대로 초등학교 3학년 학생들의 성취수준을 분석하였고, 성취수준별 학생들의 학업성취도를 분석하였으며, 3) 학생들의 반응이 특이한 문항 분석을 실시하였다.

수학과에서 학습자는 학습을 하기 전에 선수학습을 제대로 이수하지 못했을 경우 다음 학습에 곤란을 겪는다. 학습 부진아에 대한 개별적인 지도는 교육현장에서 반드시 해결해야 할 필연적인 과제이나 일선 학급 담임에게만 그 책임을 지우는 문제를 해결하기 위해 본 연구를 실시하였다. 본 연구에서는 웹기반 진단평가 시스템을 개발 및 적용하여 학습 부진아들의 학습 결손을 여부를 진단 평가 시스템을 통해 진단하고 누적된 학습 결손을 처치하여 본 학습에 도움을 주고자 하였다. 연구대상은 연구자가 근무하는 학교의 수학 기초학습 부진아 10명을 선정하였으며 수와 연산 영역을 중심으로 진단평가 시스템을 적용하였다. 그 결과 학습 부진아의 학력 향상 및 흥미를 높이는데 효과적임을 알 수 있었으며 통계처리는 F-검증(일원분산 분석)을 통해 검증한 결과 유의한 차이가 있음을 통계적으로 검증되었다.
