It can be said that the teaching and learning of mathematical problem solving has been greatly influenced by G. Polya. His heuristics shows down the explicit process of mathematical problem solving in detail. In contrast, Polanyi highlights the implicit dimension of the process. Polanyi's theory can play complementary role with Polya's theory. This study outlined the epistemology of Polanyi and his theory of problem solving. Regarding the knowledge and knowing as a work of the whole mind, Polanyi emphasizes devotion and absorption to the problem at work together with the intelligence and feeling. And the role of teachers are essential in a sense that students can learn implicit knowledge from them. However, our high school students do not seem to take enough time and effort to the problem solving. Nor do they request school teachers' help. According to Polanyi, this attitude can cause a serious problem in teaching and learning of mathematical problem solving.

The purpose of this study is to uncover weaknesses in the constructivism in mathematics education and to search for ways to complement these deficiencies. We contemplate the relationship between the capability of construction and the performance of it, with the view of the 'Twofold-Structure of Mind.' From this, it is claimed that the construction of mathematical knowledge should be to experience and reveal the upper layer of Mind, the Reality. Based on the examination on the conflict and relation between the structuralism and the constructivism, with reference to the 'theory of principle' and the 'theory of material force' in Neo-Confucianist theory, it is asserted that the construction of mathematical knowledge must be the construction of the structure of mathematical knowledge. To comprehend the processes involved in the construction of the structure of mathematical knowledge, the epistemology of Michael Polanyi is studied. And also, the theory of mathematization, the historico-genetic principle, and the theory on the levels of mathematical thinking are reinterpreted. Finally, on the basis of the theory of twofold-structure, the roles and attitudes of teachers and students are discussed.

The study provided basic data that could be used for future research by identifying trends in the factors that affect the multicultural acceptability of Korean teens from 2008 to 2017. Research methods have searched for papers using keywords from 'Multicultural', 'Youth', 'Middle School Student', 'High School Student' and 'Acceptance' in academic data base. As a result of analysis, journal articles and dissertations soared as of 2012, and the academic field identified the largest number of studies being carried out in the field of social science and pedagogy. Quantitative research and cross-sectional study were the most important methods of previous research. On the other hand, few studies have concurrently analyzed new factors related to multicultural acceptability. The results of this study indicate the need for a combined analysis of the new factors that may affect the multicultural acceptability of adolescents.

School adjustment of elementary school children is one of the most important things,sinceitisthebasisofthefuturelife. The purpose of this study was to investigate the relationships between parent-child relationship, peer relationship, teacher-child relationship, and school adjustment of elementary school students. The research topics of the present study were as follows: (1) Is the school adjustment of elementary school students different depending upon the parent-child relationship? (2) Is the school adjustment of elementary school students different depending upon the peer relationship? (3) Is the school adjustment of elementary school students different depending upon the teacher-child relationship in school? (4) Is the school adjustment of elementary school students different depending upon the grade, and sex? 460 students were sampled in Kangwon-do, and 400 were used in the final data analyses, excluding 60 due to the incomplete answering. Parent-child relationship inventory, peer relationship inventory, teacher-child relationship scale, and school adjustment scale were used. Data were analyzed using SPSS(win) 10.1K. The results were as follows: First, elementary school students adjust themselves to the school better when parent-child relationship, peer relationship, and teacher-child relationship are good. Second, teacher-child relationship has the most important effects on the school adjustment, and peer relationship, and parent-child relationship sequentially. Third, 4th graders adjust to the school better than the 6th, and there is no difference between boys and girls in terms of school adjustments. Based on the above results, discussion and implications for the future research and education were as below: First, teachers need to understand children's school adjustments depend upon their human relationships especially upon teacher-student relationships. Second, teachers need to understand students have more difficulties in adjusting to the school when they grow older. Third, teachers have to keep the children positive peer relationship, and parent-child relationship which are important in children's adjusting to the school. Fourth, future researches need nation-wide sampling and more systematized research design in order to generalize the results.

Purpose: Maintaining a lifelong health is very important. The purpose of this study is to know the perception of youth about health teacher's servant leadership, student's self-efficacy, and health promoting behavior, and the relationship among the variables. Methods: This study used surveys of health teacher's servant leadership, student's self-efficacy, and health promotion behaviors. The subjects were 1,286 elementary, middle and high school students. PASW Statistics 18.0 was used in the data analysis. Percentage, mean and standard deviation, t-test, and ANOVA test were used to compare the difference of the health teacher's servant leadership, student's self-efficacy, and health promotion behavior according to the background variables of the subject. Results: There was a statistically significant difference in the perception of youth about health teacher's servant leadership, student's self-efficacy, and health promotion behaviors according to school level, establishment type, and grade. There was also a statistically significant difference in the perception of youth about student's self-efficacy and health promotion behaviors between male and female student. In addition, student's self-efficacy serves as a positive mediator to the effects of health teacher's servant leadership on student's health promoting behavior. Conclusion: Based on these results, it needs to implement the human resources and policy support for the systematic health education of elementary, middle, and high schools, the development of the program for the teacher's servant leadership, and the health promotion of students in curriculum.

Recently, interest in programming and artificial intelligence is continuously increasing, and software education is being implemented as a mandatory education from elementary school. For efficient programming education, it is basically necessary to build a lab environment suitable for students and teachers, but there are performance problems due to the inadequacy of old computers and network equipment. Therefore, in this paper, we propose a web page-based online practice environment and algorithm competition scoring system using React and Spring boot to solve the problem of the programming practice environment. Through this, it is thought that programming learning can be carried out using only a web browser even on low-spec computers. In addition, since various programming languages can be learned irrespective of the language to be learned, it is considered that the time cost for establishing a practice environment can be reduced.

Now, more than any other time, education experts in Korea are focusing on the importance of reading. Based on this circumstance. it is necessary to introduce and develop reading assessments in the library and information science. The research introduces reading assessment tools from a psychological standpoint for the purpose of increasing reading efficiency through literature reviews. There are four categories reading attitude, interest, motivation and perception on reading. Also the research presents the suggestion to make a new reading assessment tool at a later time. When developing reading assessment tools from a psychological standpoint, it is necessary to establish the items through which how a student feels himself or herself as a reader, and subsequently how teachers, parents, and friends feel the student as a reader. Besides establishing of these appropriate items. a developer should provide directions for administration and interpretation.

This study aims to examine the differences in the longitudinal relationship between academic stress, mathematics self-efficacy, and engagement in mathematics class according to the math achievement level. According to the results, academic stress, math self-efficacy, and math class engagement were stable over time for the high and low groups. Also, In the high group, math self-efficacy had a negative longitudinal mediation effect in the influence of academic stress to math class engagement. Whereas, in the low group math class engagement had a positive longitudinal mediation effect in the influence of academic stress to math self-efficacy. This means that the academic stress affects differently according to the math achievement level, and mathematics teachers should reflect these results in their teaching/learning strategies so that students can increase their mathematics self-efficacy along with their engagement in mathematics classes.
