The purpose of this study is to investigate the characteristics of problem solving strategies that gifted students use in science inquiry problem. The subjects of the study are the notes and presentation materials that the 15 team of elementary and junior high school students have solved the problem. They are a team consisting of 27 elementary gifted and 29 middle gifted children who voluntarily selected topics related to dimple among the various inquiry themes. The analysis data are the observations of the subjects' inquiry process, the notes recorded in the inquiry process, and the results of the presentations. In this process, the knowledge related to dimple is classified into the declarative knowledge level and the process knowledge level, and the strategies used by the gifted students are divided into general strategy and supplementary strategy. The results of this study are as follows. First, as a result of categorizing gifted students into knowledge level, six types of AA, AB, BA, BB, BC, and CB were found among the 9 types of knowledge level. Therefore, gifted students did not have a high declarative knowledge level (AC type) or very low level of procedural knowledge level (CA type). Second, the general strategy that gifted students used to solve the dimple problem was using deductive reasoning, inductive reasoning, finding the rule, solving the problem in reverse, building similar problems, and guessing & reviewing strategies. The supplementary strategies used to solve the dimple problem was finding clues, recording important information, using tables and graphs, making tools, using pictures, and thinking experiment strategies. Third, the higher the knowledge level of gifted students, the more common type of strategies they use. In the case of supplementary strategy, it was not related to each type according to knowledge level. Knowledge-based learning related to problem situations can be helpful in understanding, interpreting, and representing problems. In a new problem situation, more problem solving strategies can be used to solve problems in various ways.

The purpose of this study was to examine if mothers and their children used different interaction strategies depending on the interacting contexts. Sixty-five mothers and their children were observed while they interacted with each other in two contexts, that is, a free play context and a joint problem solving context. The result of this study showed that first, the mothers' strategies and their children's strategies were closely related. When the mothers used positive strategies, their children also responded with positive strategies. In contrast, when the mothers used negative strategies, their children also tended to use negative strategies. Second, the contexts which the mothers and their children interacted affected the strategies that the mothers and their children used. The mothers and the children were more likely to use positive strategies in the context of free play than in the context of the joint problem solving. This result points out the importance of free play as the context of producing a positive atmosphere where the mothers and their children interacted positively and had a good time. Suggestions for further study and implications for parents were provided.

Purpose: The purpose of this study was to investigate the critical thinking disposition, problem solving ability, and clinical competence of nursing students in a 4-year baccalaureate university program. Methods: In this study, a descriptive survey design was used with convenience sample of 228 nursing students at a University in Chungbuk Province. Data were analyzed using descriptive statistics, independent t-test, ANOVA, Pearson correlation coefficient, and multiple stepwise regression. Results: The mean scores for critical thinking disposition, problem solving ability, and clinical competence were at the intermediate level. Significant positive correlations among critical thinking disposition, problem solving ability, and clinical competence were found. The regression model explained 46.8% of clinical competence. Problem solving confidence was the most significant predictor of clinical competence, other variables were intellectual fairness, intellectual eagerness/curiosity, and prudence. Conclusion: The study findings suggest that nursing students with higher levels of critical thinking disposition and problem solving ability will have a higher level of clinical competence. Furthermore, problem solving confidence might be the most important predictor in clinical competence. Therefore, it is necessary to introduce the new teaching strategies in nursing education, strategies that will improve critical thinking disposition, problem solving ability, and clinical competence.

The purpose of this study was to investigate knowledge types which the elementary science gifted students would use when solving a science problem, and to examine characteristics and types that were shown in the science problem solving process. For this study, 39 fifth graders and 38 sixth graders from Institute of Education for the Gifted Science Class were sampled in one National University of Education. The results of this study were as follows. First, for science problem solving, the elementary science gifted students used procedural knowledge and declarative knowledge at the same time, and procedural knowledge was more frequently used than declarative knowledge. Second, as for the characteristics in the understanding step of solving science problems, students tend to exactly figure out questions' given conditions and what to seek. In planning and solving stage, most of them used 3~4 different problem solving methods and strategies for solving. In evaluating stage, they mostly re-examined problem solving process for once or twice. Also, they did not correct the answer and had high confidence in their answers. Third, good solvers had used more complete or partially applied procedural knowledge and proper declarative knowledge than poor solvers. In the problem solving process, good solvers had more accurate problem-understanding and successful problem solving strategies. From characteristics shown in the good solvers' problem solving process, it is confirmed that the education program for science gifted students needs both studying on process of acquiring declarative knowledge and studying procedural knowledge for interpreting new situation, solving problem and deducting. In addition, in problem-understanding stage, it is required to develop divided and gradual programs for interpreting and symbolizing the problem, and for increasing the understanding.

The purpose of this study was to investigate the effects of problem solving interaction through puppetry on interpersonal problem solving thinking. The subjects were 60 children, ranging in age from 69 to 72 months. All subjects were randomly assigned to one of three experimental groups: the control group with no treatment, the puppetry group, the puppetry problem solving interaction group. The treatment covered 4 weeks. The instrument was based on Shure and Spivack's(1974) Preschool Interpersonal Problem Solving (PIPS) test. The data were analyzed with paired t-test, one-way ANOVA, Tukey test, percentage, and Kendall's ${\tau}$. There were significant differences among the three groups in the frequency of solving interpersonal problems. The problem solving interaction with puppetry group was the most effective on Interpersonal Cognitive Problem Solving Strategies. These results showed that problem solving interaction with puppetry is effective in cultivating young children's interpersonal problem solving thinking.

본 연구는 미국의 숙련된 수학 교사들의 문장제 문제 해결 지도 전략에 대한 연구이며 그것들이 학생들의 문장제 문제 해결에 어떤 영향을 끼치는지에 대한 연구이기도 하다. 관찰된 미국 교사들은 문장제 문제 해결 지도과정에 있어 공통적으로 문제의 배경에 대한 설명을 자세히 함으로써 학생들의 수학 문제해결에 대한 동기를 유발하는 공통점을 지녔고, 학생들이 문제 자체에 대해 분명히 이해할 수 있도록 만들었으며 더 나아가 학생들 자신이 다양한 해결 전략을 이용하여 문제 해결을 것이 가능케 하였다. 또한, 교사와 학생들 그리고 학생과 학생의 '의사소통'을 강조하여 언제든 자신의 수학적 아이디어를 제시할 수 있는 자유스러운 분위기를 제공하였다. '의사소통'은 교사와 학생 그리고 학생들이 문제 풀이 자체에만 얽매이지 않고 배경지식을 활용하여 문제를 이해하는 과정을 가능케 하였고, 끊임없는 질문과 의문을 통해 문제 해결전략을 세우고 그 문제를 해결하고 다시 정리하고 반성하는 전반에 걸친 원동력이 되어주었다. 또한 이 연구는 Polya의 문제해결 전략 4단계를 보완하는 모델을 제공하였다.
