Purpose: This investigation examined the effect of PBL on the meta-cognition, critical thinking, and problem solving process. Method: The research design was pre-posttest with a none qui valent control group design. Scenarios for PBL sessions were developed on the basis of textbooks and patients' charts and tested for content validity. Seventy six nursing students who took a 'Nursing Process' course from two nursing schools participated in the experimental group and control group. The experimental group performed PBL during the semester. Meta-cognition and problem solving processes were assessed by questionnaires which were developed using pedagogics. Critical thinking was measured by the CCTST(California Critical Thinking Skill Test) Form 2000. The data was analyzed by repeated measure (pretest-posttest) MANOVA, and correlation analysis. Result: PBL improved the participants' meta-cognition and problem solving process but not critical thinking. The relationship between meta-cognition and the problem solving process was supported but the relationship between critical thinking and problem solving was not supported. Conclusion: These results suggest that PBL has a positive effect on nursing students' educational outcomes. To improve the problem solving ability of nursing students, PBL should be applied to more subjects in the nursing curriculum.

Path analysis was used to determine variables influencing the creativity of elementary school children. Participants were 213 dyads of 6th-grade children and their parents. the children and their parents responded to questionnaires on children's temperament, depression, self-esteem, self-efficacy, and problem-solving style. Children completed the Torrance Tests of Creative Thinking. Child's problem-solving style and self-efficacy directly affected child's creativity. Child's temperament, depression, self-esteem, self-efficacy, and problem-solving indirectly affected creativity such that child's temperament affected depression, which affected child's self-esteem. Then, child's self-esteem affected child's problem-solving which, in turn, affected child's self-efficacy that directly predicted child's creativity. Both problem-solving and self-efficacy were mediators of child's creativity.

The aim of this study was to investigate the factors affecting earth science problem-solving performances of elementary school pre-service teachers. The participants of the study were 81 students attending an elementary school teacher education university. The instruments of the study were paper-and-pencil tests, questionnaires, and interviews. The tests mainly measured the participants' problem solving abilities in the motions of the moon and the planets. Correlation and multiple regression techniques were used for data analysis. The results demonstrated that the pre-service teachers' problem solving abilities were low. Problem-solving performances were affected by the procedural knowledge, the participants' perception of the past earth science performance, self-efficacy, and the prerequisite declarative knowledge. Contrary to our expectation, the spatial visualization ability was not found to be related to the problem-solving performances. Implications of the study are drawn, and suggestions are made for further research.

This study aims to identify the differences in chemical problem solving process of college students when the amount of information, problem context and the reasoning level were varied. Four students were participated and each student solved the problem by think-aloud method and then interviewed individually. Problem solving stage, ratio of time for each solving stage, solving strategy, misconceptions, and errors were identified and discussed related to the characteristics of problems. And, the relationships of students' belief system about chemistry & chemistry problem solving and problem solving characteristics were also identified.

This study investigated preschoolers' emotionality, emotional knowledge, event knowledge, and interpersonal problem solving strategies according to their sex and age, and the relationships among them. Subjects were 116 preschoolers (73 boys and 43 girls; 68 four- and 48 five-year-olds). Results showed that girls were higher in negative emotionality (sadness) than boys. Also, 5-year-old children were higher in emotional knowledge, event knowledge, and forceful problem solving strategies than 4-year-olds. Furthermore, children's event knowledge was positively related to their relevant problem solving strategies, while children's event knowledge was negatively related to their forceful problem solving strategies. These findings provide a preliminary evidence that children's event knowledge may predict their interpersonal problem solving strategies.

Purpose: The purpose of this study was to explore influencing factors of dysfunctional beliefs and emotion regulation strategy for nurses' problem solving ability. Methods: This study was a cross-sectional design with a sample of 745 nurses from 1 university hospital located in Gyeonggido. The scales were Dysfunctional Beliefs Test (70 items), Emotion Regulation Strategy Questionnaire (25 items) and Social Problem Solving Inventory (52 items). The data were analyzed using SPSS 17.0 employing ANOVA, pearson correlation coefficients and multiple regression analysis. Results: The mean score for problem solving ability was 11.26 points. Influencing factors for nurses' problem solving ability were identified as 'active regulation style' in emotion regulation strategy and 'negative concept of social self' in dysfunctional beliefs. Conclusion: It is plausible to assume that dysfunctional beliefs which are vulnerability factors in cognitive variables and emotion regulation strategy affect nurses' problem solving ability.

The present study examined predictors of children's problem solving using structural equation modeling(SEM). Participants were 410 dyads of 2nd- and 6th-grade children and their mother or father. Children and their parents responded to questionnaires. Instruments were the PSI(Parent Behavior Inventory, 1998), CES-D(Center for Epidemiological Scale-Depression, for children's depression, 1977) Sherer's(1982) self-efficacy scale, and the Problem Solving Inventory(Heppner & Petersen, 1982). In both grades, warmth in parenting behavior affected children's self-efficacy, which in turn contributed to their problem solving. Rejection in parenting behavior had positive effects on problem solving through increasing self-efficacy in 2nd graders only. Results implied importance of self-efficacy and developmentally appropriate parenting to improve children's problem solving.

Knowledge based system includes tools for constructing, testing, validating and refining the system along with user interfaces. An important issue in the design of a complete knowledge based system is the ability to produce explanations. Explanations are not just a series of rules involved in reasoning track. More detailed and explicit form of explanations is required not only for reliable reasoning but also for maintainability of the knowledge based system. This requires the explanation mechanisms to extend from knowledge oriented analysis to task oriented explanations. The explicit modeling of problem solving structures is suggested for explanation generation as well as for efficient and effective reasoning. Unlike other explanation scheme such as feedback explanation, the detailed, smaller and explicit representation of problem solving constructs can provide the system with capability of quality explanation. As a key step to development for explanation scheme, the problem solving methods are broken down into a finer grained problem solving primitives. The system records all the steps with problem solving primitives and knowledge involved in the reasoning. These are used to validate the conclusion of the consultation through explanations. The system provides user interfaces and uses specific templates for generating explanation text.
