  • This study was intended to find the characteristics of the middle school students' thinking processes and problem spaces when they solved the physics problems. Ten ninth grade students in Chon-Buk Do, Korea were participated in this study. The researcher investigated their thinking processes in solving 5 physics problems on electric circuit. "Thinking aloud" method was used as a research method. The students' thinking processes were recorded using an audio tape recorder and transfered into protocols. The protocols were analyzed by problem solving process coding system which was developed by Lee(1987) on the basis of Larkin's problem solving process model. The results are as follows : (1) On the average 2.85 items were solved among 5 test items, and only one person could solve all of the items correctly. (2) Problems were solved in sequence of understanding the problem, planning, carrying out the plan, and evaluating steps regardless of the problem difficulty. (3) In regard to the thinking process steps, there was no difference between the good solvers and the poor ones. But in the detail performance of problem solving, the former was different from the latter in respect with using the design of general solving procedure. (4) The basic problem spaces by the item analysis were divided into two classes. One was the problem space by using Qualitative approach in problem solving, and the other was one by using Quantitative approach. As novices in physics problem solving, most of the students used the problem space by using the Quantitative approach.

  • This study is aimed to investigate the relationship between job-related stressor, problem solving style and psychological distress and the effects of job-related stress and problem solving style on psychological distress of firefighters. The Job-related Stress Scale, Problem Solving Style Questionnaire, and the Symptom Checklist-Revised (SCL-90-R) were administered to 148 firefighters working in Seoul and Gyounggi. Correlation analysis revealed that job-related stress, problem-solving styles such as helplessness and problem-solving control correlated positively with psychological distress and that problem-solving confidence and approaching style correlated negatively with it. Multiple regression analysis showed that job-related negative cognition and emotion, helplessness and approaching style accounted for 43% of the variance in the psychological distress. Among problem-solving styles, helplessness had the highest predictive power for psychological distress. Self-reported helplessness is an important determinant of firefighters' reactions to problematic situations encountered in their job.

  • This study was conducted to investigate the degree of PSI (self-evaluative awareness of problem solving ability) in PMHNP (psychiatric mental health nurse practitioners) and to identified the factors predicting problem solving ability of them, in order to provide basic data for the development of the specific education programs to improve problem solving ability. Data was collected from 355 subjects who have the certificates of PMHNP working in hospitals and public centers. Chun Seok Kyun's instruments (1993) based on the Heppner and Petersen's Problem Solving Inventory (1982) was used to determine PMHNPs' PSI. The results were as follows; 1. The average score of PSI of PMHNP was $2.81\pm0.23$. Of the three factors. there marked the lowest score in the factor 3. personal control $(2.56\pm0.43)$, and the highest score was in the factor 1. problem-solving confidence $(2.95\pm0.34)$. 2. The differences in PSI were significant for degree of education and career in psychiatric settings (p=0.000l, p=0.0187). 3. Job satisfaction was the highest factor predicting PSI of PMHNP$(17.9\%)$. When degree of education, career in psychiatric setting and marital status were added, the total predictors explained $24.3\%$. As a result, it is necessary to conduct further research in relation to the problem-solving process, the development of education program. skill acquisition and measurement of problem solving in nursing practice.

  • In this study, the effects of grouping by extraversion and introversion in paired think-aloud problem solving using a four-stage problem-solving strategy emphasizing planning and checking stages were investigated. Prior to the instructions, the students' extraversion/introversion in three high school classes (N=87) were examined, and those classes were randomly assigned to the homogeneous, the heterogeneous, and the control groups. The test scores of the two treatment groups were significantly higher than those of the control group in the problem-solving ability. However, there were no significant differences in learning difficulty and self-efficacy. Although there were no significant differences between the scores of two treatment groups in the subcategories of the perception of treatment, the test scores of extroverts were significantly higher than those of introverts in the perception of performing listener's role, the preference to problem solving strategy, and the preference to paired think-aloud problem solving.

  • The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.
