The aim of this study is to investigate future teachers' skills that can make problem solving methods concrete for 7-11 year old students. For the students in the concrete operations level, solutions of word problems should also be taught by concreting. But most of teacher candidates can not solve the problems without algebra because they got used to solve the word problems with algebra during their high school and university education. In this study, whether the teacher candidates have the skills of solving the primary school level problems without using algebra or not are being observed. At the end of this observation it is determinated that primary level teacher candidates generally prefer using algebra operations because of their former habits. The results show that in the education of the primary level teacher candidates, there is the need of developing the solving skills using figures and diagrams without algebra rather than algebraic solutions in word problems.

Objectives: This study was carried out to provide basic materials to draw up measures for courses operation and effective clinical practice operation for the cultivation of future effective problem solving ability by identifying the relationship between problem solving ability and clinical practice satisfaction of dental hygiene students. Methods: This study targeted 215 dental hygiene students from 3 universities located in Gyeonggi-do from November 30 to December 4, 2015. We analyzed the data with frequency analysis, descriptive statistics, t-test. One-way ANOVA, Pearson correlation coefficient, Regression analysis by using SPSS. Results: Clinical practice satisfaction between grades according to the general characteristics of the study subjects was analyzed and as a result, clinical practice satisfaction showed a significant difference depending on grade (t=-2.355, p=.019), major satisfaction(F=9.548, p=.000), health status(F=4.909, p=.008). The problem solving ability according to the general characteristics of the study subjects was compared and as a result, the problem solving ability score of students 'living apart from their family or living in lodgings' was found to be higher than that of students 'living with their family' (p=.023) and the problem solving ability of students who answered 'satisfied' with their major was higher than that of students who answered 'moderate' (p=.000). As the problem solving ability and major satisfaction are higher and health status is better, clinical practice satisfaction showed higher results (p<.01). Conclusions: The above results showed a correlation between the problem solving ability and clinical practice satisfaction of dental hygiene students and clinical practice satisfaction showed higher scores as the problem solving ability level was higher. Therefore, efforts to enhance dental hygiene students' clinical practice satisfaction are considered necessary by developing and providing a program to strengthen students' problem solving ability.

Purpose:This study was conducted to identify the effects of an action learning based creative problem-solving (CPS) course on problem solving, creativity and team-member exchange in nursing students. Methods: A quasi-experimental study applying a non-equivalent control group pre-post design was employed. Sophomore nursing students (32 in the experimental group and 33 in the control group) were recruited from a university in G-city, Korea. Problem solving, creativity and team-member exchange were measured for the pretest and posttest using self-report questionnaires. Kolmogorov-Smirnov test, Chi-square, Fisher's exact test, t-test, and ANCOVA with SPSS/Win 20.0 program were used to analyze the data. Results: The scores for problem solving, creativity and team-member exchange in the experimental group were significantly higher than those of the control group. Conclusion: Results of this study indicate that an action learning based CPS course is an effective teaching method to improve nursing students' competencies. In the future longitudinal studies are needed to assess the long term effects of the course.

The purpose of this study was to examine the children's adjustment according to the their problems and problem solving pattern in single mother. The data of this study were abtained from 186 children of single-mother. For analysis of data, Factor analysis, t-test, One-way ANOVA, pearson's correlation, Multiple regression were used The results are as follows; 1. The children's problem are composed seven factors that are house life, emotion, school life, peer-relationships, academic achievement, finicial, future life. The family structural variables to have relationship with the children's problem are age, sex, father's absence reason, SES, mother postering attitude. 2. The mean value of children's problem solving pattern such as seeking religion support and passive appraisal was highest. The children's problem solving pattern were affected by mother's fostering attitude. 3. The inadequacy among children in single-mother was related to mother fostering attitude after father's loss, children's problem and children's problem solving pattern that emphasizes the interdependence of each element in this children's adjustment network.

Purpose : This study was purposed to analyze the effectiveness of PBL (Problem-Based Learning) classes and to derive class improvement plans. Methods : The subjects of the study were 48 students who took the 4th grade clinical dental hygiene course at S University located in Chungcheongnam-do of South Korea in 2021. A single-group pre and post experimental study was designed to verify whether there were significant changes in the research variables of students who participated in the class to which problem-based learning was applied. A paired-sample t-test was conducted for the collected data of 46 respondents. Results : As a result, the degree of improvement in problem clarification, cause analysis, and alternative development among the five sub-areas of problem-solving ability was statistically significant. This means that the problem-based learning class positively affects dental hygiene major students' ability to clarify problems, the ability to analyze causes to collect and analyze information, and the ability to develop alternatives to make decisions, thereby improving overall problem-solving abilities. However, the improved post-score was not statistically significant in the planning/execution and performance evaluation of the remaining two subdomains. In addition, post-scores of the leader aspect, opinion exchange, opinion evaluation, and opinion integration, which are sub-domains of collaborative self-efficacy, all showed great statistical significance. Problem-based learning improved the collaborative efficacy of dental hygiene major students overall by positively influencing the ability to lead a team, exchange and evaluate each other's views, and constructively integrate different views. Conclusion : It was found that both the subject's problem-solving ability and cooperation efficiency improved under the influence of problem-based learning. On the other hand, implications for improvement of the future class such as the necessity of supplementing strategies to promote planning and execution ability for problem solving, and ability to evaluate problem solving performance was suggested.

Owing to the limits of IT System-driven knowledge management(KM) for innovation processes, alternative KM methods has been suggested such as: (1) the knowledge network of experts or (2) communities-of-practice. This study analyzes two cases in terms of on-line expert knowledge networks for problem-solving, with the dimensions of analysis based on a theoretical framework. By analyzing the cases of S company's expert network and Naver's Ji-sik-iN, we found that system quality(e.g., ease of use, accessibility, and searching function), information/knowledge quality(e.g., usefulness, accuracy, and timeliness), knowledge-sharing culture, social capital and relevant reward systems are important for stimulating a Q&A-based problem-solving knowledge network. Implications of the findings and future research directions are discussed.

Education for the future society should emphasize the experience of sharing, coexisting, and solving problems in cooperation with each other in the community. Accordingly, in addition to the problem-solving capability, which is the ultimate goal of mathematics education, it is necessary to strengthen the capability to solve unstructured problems through collaboration. This study attempted to suggest that solving complex problems through collaboration is used in school classes or gifted education by introducing polymath that solves problems using collective intelligence. Accordingly, a target problem was set and an example of polymath in which community members exert each other's intelligence to solve the problem. In addition, by investigating the perceptions of students who have experienced polymath, positive aspects and improvements of polymath were suggested. Through this, this study can contribute to revitalization of mathematics teaching and learning methods using collective intelligence.
