  • 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.

  • 2상유동의 물리적 문제는 이상화된 계면형상, 경계 및 초기조건과 연속체공식화를 이용한 지배 및 구속관계에 의해 정립된다. 본 글에서는 2상유동모델의 공식화에 대한 근거와 응용의 제한 성등이 제시되었다. 각 2상유동모델들 사이에는 많은 차이점이 존재하고 이들은 모두 주어진 경우에 적절한 평균화 과정에 의해 유도되었다. 2상유동모델링의 가장 큰 어려움은 구속관계의 개발과 관련되어 있으며 실험적 결과와의 송환과정을 통하여 향상될 수 있을 것이다. 구속 조 건의 개발과 함께 2상유동모델링에 대한 연구는 미시적인 동적해석을 위한 다차원 2-유체모델과 총체적인 계의 거동해석을 위한 1차원 2-유체모델, 혹은 단일유체모델의 분야에서 계속 진행되 어야 할 것이다.
