The purpose of this study was to investigate the moderating effect of cultural disposition in the relationship between parenting and academic achievement. Five-hundred thirty five middle school students(male 247; female, 288) participated in this study, These students completed parenting scale and Individualism-Collectivism Scale. Academic achievement was calculated using academic scores from language, english, mathematics and science. Collected data were analyzed using multiple regression. The major findings of this study can be summarized as follows. First, parenting was significantly associated with academic achievement albeit weak. Second, influence of affective and autonomy parenting on academic achievement for both father and mother were not significant. Third, moderating effects of individualism were significant in only fathers' autonomy parenting. Fourth, moderating effects of collectivism were significant in fathers' affective parenting and autonomy parenting. These results were discussed in relation to pervious studies. Finally limitations were commented and future study were suggested.

The purpose of this study was to examine the effects of abstraction offer of basic concept principle and feedback of self-efficacy attributional and mathematical study ability of math underachievers in high school based on the attribution theory and self-efficacy theory. The hypothesis were posed as below : Hypothesis 1: The experimental group that takes the abstraction offer of concept principle and attributional feedback training would be better at most self-efficacy than the control group that doesn't. Hypothesis 2: The experimental group that takes the abstraction offer of concept principle and attributional feedback training would have better math achievement than the control group that doesn't. They were divided into an experimental group and a control group, and the attribution disposition, self-efficacy and academic achievement of the children were measured by pretest and posttest. For data analysis, SPSS/PC+ program was employed and t-test was conducted. The main findings of this study were as below : First, the abstraction offer of concept principle and attributional feedback training was effective for enhancing the math self-efficacy in high school underachievers. Second, the abstraction offer of concept principle and attributional feedback training was effective for increasing the math achievement in high school underachievers.

This study examines how elementary students understand fractions with operations conceptually and how they perform procedures in the division of fractions. We attempted to look into students' understanding about fractions with divisions in regard to mathematical proficiency suggested by National Research Council (2001). Mathematical proficiency is identified as an intertwined and interconnected composition of 5 strands- conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. We developed an instrument to identify students' understanding of fractions with multiplication and division and conducted the survey in which 149 6th-graders participated. The findings from the data analysis suggested that overall, the 6th-graders seemed not to understand fractions conceptually; in particular, their understanding is limited to a particular model of part-whole fraction. The students showed a tendency to use memorized procedure-invert and multiply in a given problem without connecting the procedure to the concept of the division of fractions. The findings also proposed that on a given problem-solving task that suggested a pathway in order for the students to apply or follow the procedures in a new situation, they performed the computation very fluently when dividing two fractions by multiplying by a reciprocal. In doing so, however, they appeared to unable to connect the procedures with the concepts of fractions with division.

본 연구는 개인의 의사결정 과정에서 자신이 가지고 있는 확률적 지식과 자신이 선택한 결과 사이에 간극이 발생하는 현상을 분석해 봄으로써 수학영재학생들을 위한 확률문제 지도시 고려해야 할 점들을 알아보는 것이다. 이를 위해 23명의 6학년 수학영재 학생들에게 확률과 기댓값의 개념이 내재된 확률 문제 5개(조건이 하나씩 변하는 시리즈)를 제시하고 그들의 선택에 영향을 미친 요인들을 분석하고 이를 시각화하였다. 초등수학영재학생들이 선택한 결과와 그 근거에 대한 분석은 수업 관찰 및 비디오 분석, 학습지 분석, 그리고 관찰자의 면담의 삼각분석법을 사용하였다. 결과 분석을 통하여 영재학생들에게 확률 문제를 지도할 때 고려해야 할 교육적 시사점을 제시하였다.
