2022 개정 교육과정에서 AI교육의 도입에 따라 데이터 관련 교육의 필요성이 대두되고 있는 상황에서 학생들의 데이터 기반 문제해결력을 향상 시키는 것이 필요하다. 본 연구는 이러한 필요성에 따라 학생들의 데이터 기반 문제해결력을 향상하기 위한 SW교육에 대한 방안을 연구하고자 한다. ADDIE 교수설계모형을 바탕으로 프로그램을 설계하였고, 교사를 대상으로 요구분석 설문조사를 실시하여 요구 분석을 실시하였다. 요구분석 결과에 근거하여 마이크로비트를 활용한 데이터 기반 문제해결을 주제로 교육 프로그램을 설계하였다. 본 연구에서는 데이터 기반 문제해결의 중요성과 그 역량의 필요성을 제기하였다. 후속 연구에서는 데이터 기반 문제해결 SW 교육이 문제해결력에 어떤 유의미한 효과성을 나타낼지 밝히는 것이 필요하다.

본 연구는 문제해결능력과 자살사고와의 관계에서 우울의 매개효과를 검증하고자 하였다. 이를 위해 대학생 548명을 대상으로 지각된 문제해결능력 척도, 우울 척도 및 자살사고 척도를 실시하였다. 이들 변인들 간의 관계를 알아보기 위해 상관 분석하였고, 우울의 매개효과를 검증하기 위하여 회귀분석을 실시하였다. 연구 결과 문제해결능력과 우울 및 자살사고 간에 유의한 정적 상관을 보였고, 문제해결능력과 자살사고 간의 관계에서 우울의 매개효과가 검증되었다. 즉 지각된 문제해결능력은 자살사고에 직접 영향을 미치기보다는 우울을 매개로 간접적으로 영향을 미치는 것으로 확인되었다. 이 같은 연구결과는 자살사고에 영향을 미치는 우울과 문제해결능력에 대한 중재의 중요성을 시사하였다.

The purpose of this study was to analyze students' physics problem solving processes and to find the patterns of their problem spaces when high school and university students solved the physics problems. A total of 51 students in a high school and in two universities participated in this study. Their thinking processes in solving 5 physics problems on electric circuit were recorded by using 'thinking aloud' method and were transferal into protocols. 'The protocols were analyzed by the coding system of problem solving process. One of the major theoretical contributions of the computer simulation approach to problem solving is the idea of problem space. Such a concept of problem space was applied to physics problems on electric circuit in this study, and students' protocols were analyzed by the basic problem spaces which were made up from the item analysis by the researcher. The results are as follows: 1) On the average 4.0 test items among 5 ones were solved successfully by all subjects, and all of the items were solved correctly by only 19 persons among all of them. 2) In regard to the general steps of problem solving process, there was little difference for each item between the good solvers and the poor ones. But according to the degree of difficulty of task there was a good deal of difference. For a complex problem all of 4 steps were used by most of students, but for a simple one only 3 steps except evaluating step were used by most of them. 3) It was found in this study that most of students used mainly the microscopic approach, that is, a method of applying Ohm's law on electric circuit simply and immediately, not using the properties of electric circuits. And also it was observed that most of students used the soloing tom below, that is, a solving path in which they were the first to calculate physical Quantities of circuit elements, before they caught hold of the meaning of the given problem regardless of the degree of difficulty.

This research is a case study of the changes of students's problem solving ability and affective characteristics when we apply to general students MG-CPS model which is creative problem solving model for gifted students. MG-CPS model which was developed by Kim and Lee(2008) is a problem solving model with 7-steps. For this study, we selected 7 first grade students from girl's high school in Seoul. They consisted of three high level students, two middle level students, and two low level students and then we applied MG-CPS model to these 7 students for 5 weeks. From the study results, we found that most students's describing ability in problem understanding and problem solving process were improved. Also we observed that high level students had improvements in overall problem solving ability, middle level students in problem understanding ability and guideline planning ability, and that low level students had improvements in the problem understanding ability. In affective characteristics, there were no significant changes in high and middle level classes but in low level class students showed some progress in all 6 factors of affective characteristics. In particular, we knew that the cause of such positive changes comes from the effects of information collection step and presenting step of MG-CPS model.

The purpose of this study is to analyze thinking process in problem solving and to get some teaching materials to improve students' problem solving abilities. For this study, 14 girl and boy students in highschool were tested with 7 testing questions. The whole process of students' problem solving was observed by using 'Thinking aloud', recorded by Audio Tape and finally drawn up to Protocol. On the basis of that Protocol, coding system was set up and characteristics of thinking process in each stage were analyzed. -In the stage of planning, successful problem solvers tried to check the properties of words included in problems(Pr) and made it clear that they were seeking(O) -In the stage of planning, students used abstraction strategy(Ab, making equation(E) or using variable(V)) appropriately could solve more difficult problems. Successful problem solvers turned used unsystematical trial into systematical method and were good at using partial objects, assistant factors. - In the stage of carring out the plan, successful problem solvers to reduce the error, check the purpose, used formula, knowledge and calculation. -In the looking back stage, successful problem solvers generalized the answer and checked the total process.

This study examined effects of children's emotionality, interpersonal problem solving strategies, and maternal behaviors during mother-child interaction on children's social competence as rated by teachers. Data were analyzed separately for boys and girls. A total of 102 children(60 boys, 42 girls; aged 5-6) and their mothers were studied. Children's positive and negative emotionality were related to their social competence. Positive solving strategies were positively related to boy's social competence; negative solving strategies had negative to both boy's and girl's social competence. Mother's negative affect related negatively to boy's social competence and mother's sensitivity/guidance related positively to girl's social competence. When children's emotionality and interpersonal problem solving strategies were controlled, maternal behaviors during mother-child interaction did not contribute to children's social competence.

This study is to evaluate the effect of roleplaying-centered STS program on the science-related attitude, the academic achievement, and the problem solving ability in "Environment" unit of high school Science. 90 students in grade 10 were divided into two groups, the experimental group applied the roleplaying-centered STS program and the control group applied the traditional lecture-centered class. The pretest was implemented to measure the science-related attitude, and the posttest was implemented to measure the science-related attitude, the academic achievement, and problem solving ability. The collected data were analyzed by ANCOVA and Correlation Analysis with SPSS program. The results are as follows: First, the experimental group was not significantly different from the control group in the science-related attitude and in the academic achievement(p>.05). Second, the experimental group significantly showed much better problem solving ability than the control group(p<.05). Third, a significant correlation was recognized between the academic achievement and the problem solving ability(p<.01).

The present study examined variables relevant to problem solving in childhood to determine predictive contributions of such variables as parenting style, child's temperament, self-esteem, depression, and self-efficacy. Subjects were 545 2nd, 4th, 6th grade elementary school children and their parents. Data were analyzed with bivariate correlation, multiple regression, and step-wise multiple regression. Results indicated that child's temperament and self-efficacy were significantly correlated with problem-solving, and self-efficacy was the most critical predictor of problem solving.

The purpose of the study was to investigate the relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. fifty-four children aged 5 and 6 years and their mothers were observed and videotaped in a strange situation. Children were interviewed in order to assess interpersonal cognitive problem solving skill. teachers rated children's social development using modified ISCE(Iowa Social Competency Scale : Preschool Forma). The results showed that there were significant relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. children of the secure attachment to mothers were greater social activator, cooperative, alternative solution thought and consequential thought. In contrast, children of insecure attachment to mother were less social activator and cooperative, and more hypersensitive and apprehensive. Children's social competence was related to the interpersonal cognitive problem-solving skill.
