분자 수준의 그림과 4단계 문제 해결 전략을 제시한 후 해결자 청취자 활동을 통해 문제 해결 과정을 점검하도록 한 교수 방법의 효과를 조사하였다. 고등학교 4학급(191명)을 선정하여 개별적으로 전략을 사용하는 집단(St; Strategy), 해결자 청취자 활동을 하는 집단(SL; Solver' Listener), 전략을 사용하며 해결자 청취자 활동을 하는 집단 (St-SL; Strategy-Solver' Listener), 그리고 통제 집단으로 무선 배치하였다. 전략 수행 능력 검사에서 St-SL 집단의 점수가 통제 집단에 비하여 유의미하게 높았으나, 객관식 문제 해결력 검사에서는 유의미한 차이가 나타나지 않았다. 전략 수행 능력 검사의 하위 범주들에서는 문제의 조건을 파악하거나 올바른 물리량을 유도해내는 능력은 향상된 데에 비하여, 하위 목표를 설정하거나 해결 과정을 검토하는 능력은 매우 낮은 것으로 나타났다. 전략에 대한 선호도는 St 집단보다 St-SL 집단에서 보다 긍정적인 것으로 조사되었다.

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.

This study aims to identify the characteristics of gas phase problem solving of college freshmen. Four students were participated in this study and solved the problem by using think-aloud method. The thinking processes were recorded and transferred into protocols. Problem solving stage, the ratio spended in each solving stage, solving strategy, misconceptions, and errors were identified and discussed. The relationships between students' belief system about chemistry problem solving and problem solving characteristics were also investigated. The results were as follows: 1. Students felt that chemical equation problem was easier than word problem or pictorial problem. 2. When students had declarative knowledge and procedural knowledge required by given problem, their confidence level and formula selection were not changed by redundunt information in the problem. 3. When the problem seemed to be difficult, students tended to use the Means-End or Random strategy. 4. In complicated problems, students spent longer time for problem apprehension and planning. In familiar problems, students spent rather short time for planning. 5. Students spent more time for overall problem solving process in case of using Means-End or Random strategy than using Knowledge-Development strategy.

The purpose of this paper is to analyze the selection difference of mathematical problem solving strategy by mathematical learning style, that is, the intellectual, emotional, and physiological factors of students, to allow teachers to instruct the mathematical problem solving strategy most pertinent to the student personality, and ultimately to contribute to enhance mathematical problem solving ability of the students. The conclusion of the study is the followings: (1) Students who studies with autonomous, steady, or understanding-centered effort was able to solve problems with more strategies respectively than the students who did not; (2) Student who studies autonomously or reconfirms one's learning was able to select more proper strategy and to explain the strategy respectively than the students who did not; and (3) The differences of the preference to the strategy are variable, and more than half of the students were likely to select frequently the strategy 'to use a formula or a principle' regardless of the learning style.

This study aimed to identify the causal relationships among self-regulated learning strategy, problem solving efficacy, task value and learning outcome, and mediation effect of self-regulated learning strategy in engineering capstone design course. The data were collected from 363 university students who enrolled in capstone design courses and analyzed using structural equation modeling method. The results were: first, problem-solving efficacy and task value exerted significant effects on self-regulated learning strategy. Second, self-regulated learning strategy exerted significant effects on learning outcome, but problem-solving efficacy and task value did not. Third, problem-solving efficacy and task value showed significant indirect effects on learning outcome, which confirmed that self-regulated learning strategy fully mediated between two exogenous variables and learning outcome.

This study investigated the relationship between elementary school students' creative problem solving skills in terms of science and cognitive strategies. Creative problem solving in science was measured by 4 variables; appropriateness, scientific ability, concreteness, and originality. Cognitive strategies were measured by 6 variables; surface(rehearsal), deep(elaboration and organization), and metacognitive strategies(planning, monitoring, and regulating). The KEDI Creative Problems Solving Test in Science(Cho et al., 1997) and the Motivated Strategies for Learning Questionnaire(Pintrich & DeGroot, 1990) were administered to 72 subjects. Data were analyzed by means of Pearson's correlation and multiple regression analysis. Our findings indicated a positive correlation between creative problem solving in science and cognitive strategies. The surface cognitive strategy (rehearsal) positively predicted the total score, the scientific ability's score, the concrete score, and the original score of creative problem solving in science. The deep cognitive strategy(organization) positively predicted the appropriate score and the metacognitive strategy(planning) positively predicted the original score of scientific creative problem solving skills.

This study intended to find the differences between expert's and novice's thinking processes when they solve physics problems. Five physics professors and twenty sophomore students in a physics department were participated in the study. The researcher investigated their thinking processes in solving three physics problems on NEWTON's law of motion. The researcher accepted so called "Thinking Aloud" method. The thinking processes were recorded and transfered into protocols. The protocols were analysised by problem solving process coding system which was developed by the researcher on the basis of Larkin's problem solving process model. The results were as follows: (1) There was no difference of time required in solving physics problem of low difficulty between expert and novices; but, it takes 1.5 times longer for novices than experts in solving physics problems which difficulties are high and average. (2) Novices used working forward strategy and working backward strategy at the similiar rate in solving physics problems which difficulties were average and low. while Novices mo mostly used working backward strategy in solving physic problems which difficulty was high. Experts mostly used working forward strategy in solving physics problems whose difficulties was average and low, however experts used working forward strategy and working backward strategy at the similiar rate in solving physics problem which difficulty was high. (3) Novices usually wrote only a few information on the diagram of figure they drawn, on the other hand experts usually wrote almost all the information which are necessary for solving the problems. (4) Experts spent much time in understand the problem and evaluation stage than novices did, however experts spent less time in plan stage than novices did. (5) Physics problems are solved in sequence of understanding the problem, plan, carrying out the plan, and evaluation steps regardless of problem difficulty.

본 연구에서는 문제 해결 전략에서 시각적 조직화와 협동학습의 효과를 조사하였다. 고등학교에서 세학급 (N=127)을 선정하여 시각적 조직화를 이용한 문제 해결 전략을 개별적으로 사용하는 집단(SV), 협동학습 환경에서 사용하는 집단(SVC ), 그리고 통제집단으로 배치하였다. 수업 처치 후 객관식 문제 해결력, 전략 수행 능력, 화학 학습에 대한 불안, 수업참여도, 학습 동기를 조사하였다. 연구 결과 객관식 문제 해결력에서는 집단간 차이가 유의미하지 않았으나, 전략 수행 능력에서는 수업 처치의 주효과가 나타났다. SV 집단과 SVC 집단의 점수가 통제 집단보다 높았으며, 특히 하위 영역 중 문제 이해와 관련 법칙 회상에서 높은 점수를 보였다. 수업 참여도와 학습 동기 검사에서도 SV 집단과 SVC 집단의 점수가 통제 집단보다 유의미하게 높았다. 그러나 시각적 조직화를 이용한 문제 해결 전략이 학생들의 화학 학습에 대한 불안을 유의미하게 감소시키지는 못했다.
