이 연구의 목적은 고등학생들의 독창적인 문제발견 능력과 과학 학업 성취도, 과학 탐구능력, 창의적 성격 사이의 관계를 알아보는 것이다. 발견된 문제의 독창성을 평가하기 위해 빈도수에 의한 평가와 교사와 학생에 의한 주관적 판단에 의한 평가 방법을 사용하였다. 그 결과, 세 가지 평가 방법은 큰 차이가 없었으나, 빈도수에 의해 평가할 경우 친숙한 문제가 더 높은 점수를 받을 가능성이 있는 것으로 나타났다. 또한 전체 학생들의 독창적인 문제발견 능력은 학업 성취도 및 창의적 성격과 정적 상관이 있었으나, 과학 탐구능력괴는 상관이 없었다. 그러나 독창성 점수가 높은 상위 집단에서는 창의적 성격과 정적 상관이 있었으며, 하위 집단에서는 학업 성취도와 정적 상관이 있었다. 또한 독창성 점수가 높은 상위 집단과 하위 집단 간의 과학 탐구능력과 창의적 성격은 유의미한 차이가 없었으며, 학업 성취도는 물리I과 화학I 과목에서만 유의미한 차이가 있었다. 앞으로 문제발견 능력을 평가하기 위한 평가 방법에 관한 연구와 함께 독창적인 문제발견 능력에 영향을 미치는 다양한 변인에 대한 연구가 수행되어야 할 것이다.

High school students' achievements in algorithmic problems, and figure-formatted and textual-formatted conceptual problems concerning stoichiometry, gaseous state, and solution, were measured by the Chemistry Problem Solving Ability Test. The relationships among the achievement scores in the three types of problems and cognitive variables such as logical thinking ability, mental capacity, and field dependence/field independence were examined. The portion of variance of explanation for each achievement score was also studied by a multiple regression analysis. The results showed that logical thinking ability was significantly correlated with the achievement score in the algorithmic problems, and accounted for the significant portion of the variance of the score. Mental capacity accounted for the significant portion of the variance of the score in the figure-formatted conceptual problems. Although field dependence/field independence was significantly correlated with all the achievement scores, it did not significantly account for any scores in multiple regression analyses. However, the magnitudes of correlation coefficients among the achievement scores were higher than those between the achievement scores and cognitive variables. The best predictor for each score was also found to be one of the other achievement scores. Educational implications are discussed.

The purpose of this study was to find out effect of problem solving by mental demand of items and chunking level of problem solver on the item. The principal findings of study were as follows ; 1) According to increase of mental demand of items. students' achievement score appeared to decrease and the more mental demand an item needed. the higher or at least the same hierarchical item was. These results showed that mental demand of item was main factor which decided difficulties of problem solving. 2) Though items have the same mental demand. students' achievement score were different between balance beam task and 2nd law task (achievement score of balance beam task < achievement score of 2nd law task). 3) Achievement score of LM group who used chunked knowledge to solve balance beam task were higher than non LM group who used non chunked knowledge. 4) The level of chunked knowledge was different between two tasks when non LM group solved items of two tasks. On the other hand, LM group used the same level of chunked knowledge to solve items of two tasks. 5) Achievement score of non LM group was the same between items of two tasks after treatment due to chunking effect by treatment. But achievement score of LM group didn't change before and after treatment. The chunking effect by treatment had an effect on non LM group, but it was not on LM group.

The purpose of this study is to determine which variable is the best predictor of students' science-related attitudes. Three influential variables were tested : students' science achievement. students' science process skills, and teachers' attitudes toward science. This study has been made on the basis of questionnaire from 205 1st graders in 5 different middle schools in Seoul. The instruments used for measuring attitudes were TOSRA and the questionnaire developed by Sung-Jae Pak(1980). The instrument used for measuring science process skills was a standardized test developed by Youne-Woo Lee(1989). The results was analyzed by multiple-regression in the statistical packages SPSS/PC+. The major findings of this study are as follows. 1. The mean score of students' science-related attitudes was 66.8, and there was no significant difference according to gender of students and teachers(p> .05). 2. The mean score of students' science process skills was 61.1, and there was no significant difference according to gender of students and teachers(p> .05). 3. Students' science process skills was the best predictor of students' science-related attitudes among three variables(R=0.3102, p< .05). 4. The subjects were divided into 2 groups by students' science achievement. In the high score group, students' science achievement was the best predictor of students' science-related attitudes (R=0.3406, p<.05). And in the low score group, none of the variables was related to students' science-related attitudes (p> .05). 5. In students who has a male science teacher, students' science process skill was the best predictor of students' science-related attitudes (R=0.3220, p<.05).

Purpose: The purpose of this study was to examine the mediating effect of major satisfaction in the relationship between academic self-efficacy and academic achievement among nursing students. Methods: Data were collected from 142 nursing students from March 5 to March 9, 2018, and the collected data were analyzed using SPSS version 21.0 for Windows. Results: Academic self-efficacy had a significant effect on both major satisfaction (${\beta}=.31$, p<.001), and academic achievement (${\beta}=.43$, p<.001). The parameter of major satisfaction was found to have a significant effect on the dependent variable, academic achievement (${\beta}=.22$, p=.007), and the independent variable, academic self-efficacy, also had a significant effect on academic achievement (${\beta}=.39$, p<.001). Thus, major satisfaction was found to have a partial mediating effect on the relationship between academic self efficacy and academic achievement. The Sobel test showed that the path of the academic achievement and academic self efficacy variables was significantly mediated by major satisfaction (Z=2.99, p=.003). Conclusion: Academic self-efficacy was found to affect academic achievement, and major satisfaction was found to play a partial mediating role in the relationship between academic self efficacy and academic achievement.
