This study has attempted to find the teaching methods for the elementary students with low science achievement by examining the differences of science learning motivation, academic stress and stress coping styles and the characteristics shown in the relationship between them. To achieve this, the differences of science learning motivation, academic stress and stress coping styles of the elementary students with low science achievement and their relationship was set up as a study problem. A science learning motivation using a science learning motivation questionnaire reconfigured with PALS along with underachievers diagnosis were measured targeting 660 elementary students located in Seoul. Using an academic stress questionnaire and stress coping style questionnaire, an academic stress and stress coping styles were measured. The results of analyzing the collected data are as follows. First, a science learning motivation of elementary students with low science achievement was lower than the general students but the academic stress was shown higher. Especially, the self-efficacy of science learning motivation was significantly lower and the school stress was highest. For stress coping styles, a tendency of passive and avoidment coping styles were shown higher than the general students. Second, among the science learning motivation of elementary students with low science achievement, the self-efficacy motivation and school stress have shown a negative correlation but had a positive correlation with the goal-oriented motivation centered on ability. In the correlation between the science learning motivation of elementary students with low science achievement and the stress coping styles, the pursuit of social support coping styles have shown a significant positive correlation with the science learning motivation and its subcategories. As a result of conducting a regression analysis on the influence of academic stress and stress copying styles on the science learning motivation of elementary students with low science achievement, among the academic stresses, the school stress was shown to have the biggest influence. Among the stress coping styles, the pursuit of social support coping styles had the biggest influence on the science learning motivation followed by active coping behaviors, passive and avoidment coping behaviors. Low science learning motivation as underachievement factors of elementary students with low science achievement was identified as having a relationship with high school stress and undesirable stress copying styles. Therefore, guidance and a program are required for the elementary student with low science achievement to have desirable stress coping methods on the stressful situations. In addition, for the improvement of science learning motivation, a learning environment is needed for the elementary students with low science achievement with seeking of relevant educational methods.

This study was conducted to examine the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness. The sample included 308 early childhood education major students, and the data were collected using the Modified Orientation to Teach Survey (MOTS), Teaching-belief type scale, and self-directed learning readiness scale. A statistical analysis included correlation analysis and stepwise multiple regression analysis. The results were as follows: 1) analysis of the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness conveys that intellectual stimulation and self-directed learning had the strongest relationships while nature of work had the weakest. For educational belief and self-directed learning readiness, maturationism and interactionism showed significantly positive correlations while behaviorism displayed a negative correlation. Behaviorism had a significantly negative correlation with openness for challenge, a sub-factor of self-directed learning. 2) Analysis of the effect of pre-service early childhood teacher's motivations of choosing a teaching profession and educational belief on self-directed learning readiness indicates that pre-service early childhood teacher's motivations of choosing a teaching profession had a stronger effect on self-directed learning. These results suggest the following: successful performance as an early childhood teacher not only requires receiving institutionalized education but also self-directed learning while working as an early childhood teacher.

다층퍼셉트론의 계층별 학습 방법의 하나인 Ergezinger 방법은 출력 노드가 1개로 구성되어 있고, 출력층의 가중치를 최소자승법으로 학습하기 때문에 출력층의 가중치에 조기포화 현상이 발생할 수 있다. 이런 조기 포화현상은 학습 시간과 수렴 속도에 장애가 된다. 따라서, 본 논문은 Ergezinger의 학습 방법을 출력층에서 벡터 형태로 학습할 수 있는 알고리즘으로 확대하고 학습 시간과수렴 속도를 개선하기 위해서 학습 상수를 도입한다. 학습상수는 은닉층 가중치 조정 시, 새로이 계산된 가중치와 기존 가중치의 상관 관계를 계산하여 학습 상수에 반영하는 가변적인 방법이다. 실험은 제안된 방법과 기존 방법의 비교를 위해서 iris 문제와 비선형 근사화 문제를 대상으로 실험하였다. 실험에서, 제안 방법은 기존 Ergezinger 방법보다 학습 시간과 수렴 속도에서 우수한 결과를 얻었으며, 상관 관계를 고려한 CPU time 측정에서도 제안한 방법이 기존 방법보다 약 35%의 시간을 절약할 수 있었다.
