The discovery method is known to be the most effective in improving students' mathematical thinking. Recently, the long-term slow thinking(LST) is suggested as a possible method to implement the discovery method into the real classroom. In this concept, we examined whether students can solve such a problem, as appears to be beyond their ability, by themselves(LST) or not. 10 middle school students of the ninth grade were selected for the study, who had no previous experience on the infinite concept of calculus of the high school course. They had tried to solve a problem about the calculus by their LST for three days. Two of students solved the problem by themselves and seven of students solved it with help of hints. This result shows that if students are given the opportunity of LST for rather difficult mathematical problem with appropriate guidance of a teacher, they might solve it by themselves. That is, LST could be a possible method for implementation of the discovery method.

The purpose of this study was to develop a school violence prevention program featuring the Practical Action Teaching Model(hereafter, PATM) for middle school students to prevent school violence by Home Economics Education. To accomplish this purpose, the processes of analysis, design, development, and evaluation based on ADDIE were conducted. The validity of the program was evaluated twice by Home Economics education experts(36 experts for the first group and 10 experts for the second group) and the contents of the program were modified according to the comments from the evaluators. The school violence prevention program in Home Economics classes consisted of 5 topics such as changing perception on school violence, enhancing self-esteem, relating with others, practicing consideration and sharing, and strengthening the will of preventing school violence. Twenty-four units were developed with 7 practical problems(What should I do to make friends to help with each other?, What should I do to establish positive self-concept?, What should I do to communicate to build good relationship?, What should I do to solve the conflicts peacefully?, What should I do to practice consideration and sharing in food consumption?, and What should I do to practice consideration and sharing in clothing?) in 5 topic areas. Teaching-learning plans included four steps such as problem perception, practical reasoning, action, and evaluation that comprise PATM to solve the practical problems. Every step of the teaching-learning plan consisted of questions for practical reasoning and activity assignments. Materials for students and teachers were developed. Materials for students comprised 80 pieces in total including student activity, reading, movie, and clips to make students enhance understanding and interest. Materials for teachers comprised 35 pieces in total such as rationales, newspaper articles, and movies that make teachers that lesson teaching loads and were helpful for teachers. The PATM was incorporated into developing the program and a Likert-scale was used to assess usefulness, applicability, appropriateness, fidelity, substantiality, and validity of this program. This program gained more than 4.00 on a 1-5 Likert scale. This result indicated that program is expected to be effective and useful to school violence prevention.

This paper suggests that the meaning and the direction of character education should be understood and approached from a point of view which human formation is regarded as the essence of education. The best way of approach to the character education with this point of view could start from the teachers' character, because teachers are key actors for character formation of students. This study therefore places strong emphasis on the importance of teachers' character and suggesting liberal education, as a key solution, its aim is raising and developing the whole human being. The purpose of this study is to explore the possibility of liberal teacher education. With this purpose of study, the author argues the moral dimension of teaching and the importance of the teachers' role as a character builder in ch.II. In ch.III, the present state of teachers' character education is examined and is argued the necessity of liberal perspective for teacher education to stress the character formation of teachers. The liberal teacher education means that the teacher education is integrated into the quality of liberal education which emphasizes the whole human formation, transformation of personality and critical reflection for human formation. The ch. IV contains exploration of the possibility of liberal teacher education by discussing the compatibility between liberal education and vocational education. Furthermore, it covers how teacher education can reflect the quality of liberal education on the aim of teaching, contents and methods of teacher education concretely.

We developed $21^{st}$ century scientific literacy assessment instrument and applied it to explore the contents of seven Korean science textbooks. The $21^{st}$ century scientific literacy assessment instrument involved three dimensions (habits of mind, character and values, science as human endeavor). Each dimension consists of three sub-dimensions. Five science education experts assessed the content of textbook using criteria. We discussed issues in which the examiners responses did not match and reached an agreement on initial disagreement. As a result, we found that most Korean textbook contained contents on habits of mind, especially, communication, collaboration, and information management. We also found that most materials lacked information about character and values and science as human endeavor. Based on the result, we suggest that researchers and science educators need to consider all dimensions of the $21^{st}$ century scientific literacy when they develop curriculum and teaching materials. In addition, the rubric for $21^{st}$ century scientific literacy can be adopted as an assessment tool for examining curriculum, teaching materials.

The knowledge-information-processing competency is the most essential competency in a knowledge-information-based society and is the most fundamental competency in the new problem-solving ability. Data-driven science inquiry, which emphasizes how to find and solve problems using vast amounts of data and information, is a way to cultivate the problem-solving ability in a knowledge-information-based society. Therefore, this study aims to develop a teaching-learning model and strategy for data-driven science inquiry and to verify the validity of the model in terms of knowledge information processing competency. This study is developmental research. Based on literature, the initial model and strategy were developed, and the final model and teaching strategy were completed by securing external validity through on-site application and internal validity through expert advice. The development principle of the inquiry model is the literature study on science inquiry, data science, and a statistical problem-solving model based on resource-based learning theory, which is known to be effective for the knowledge-information-processing competency and critical thinking. This model is titled "Exploratory Scientific Data Analysis" The model consisted of selecting tools, collecting and analyzing data, finding problems and exploring problems. The teaching strategy is composed of seven principles necessary for each stage of the model, and is divided into instructional strategies and guidelines for environment composition. The development of the ESDA inquiry model and teaching strategy is not easy to generalize to the whole school level because the sample was not large, and research was qualitative. While this study has a limitation that a quantitative study over large number of students could not be carried out, it has significance that practical model and strategy was developed by approaching the knowledge-information-processing competency with respect of science inquiry.

For all the region is the basic unit of geographical learning and the grounds of human activities, regional learning can't possible be carried out at the class. Because there are very few regional learning materials that are applicable to class and can be expanded to geographical basic concept. This paper aims to regulate the construction principles of regional learning and select the contents of regional learning. Firstly, the six basic concepts of geographical education be made a selection of the construction principles of regional learning: human-environment, location, region, interaction, change, scale. And then, I suggest the upper five subject that be based on the results of systematical geography. Those are the necessity and method of regional apprehension, the physical environment and the regional human-life, the resource and industrial activities. the regional life-space's formation and change, and the changing world and region. And I propose the subdivided the mid and the lower subject that be reflected the learner's need and the social demand, and could be experienced the results of geography and the everyday life. For the best regional learning, these subjects can be combined one or more in various scale.

과학교육에서의 문제해결력의 강조는 그 긴 역사를 가지고 있으나, 인지 심리학에서의 정보처리 모형을 사용한 문제해결과정의 분석이 사용되면서 그 교수가능성이 높아지고 있다. 본 연구는 하나의 탐색연구로써 학습자들이 물리문제를 해결하려는 과정에서 그 문제를 자기나름으로 이해하여 만든 내적표상과 동원한 해결방안이 문제해결에 어떤 관련이 있는지를 알아내보려고 한다. 물리전공 박사과정 학생 3명을 전문가로, 고등학생 2명과 대학 1년생 4명, 모두 6명을 초보자로 삼아 역학내용을 다룬 세 문제를 소리내어 푸는 과정을 개인별로 녹음하여 그 문제해결과정들을 분석하였으며, 학생들의 사고수준을 알기위해 사고 수준검사가 실시 되었다. 주로 질적 분석을 사용했으나 그 결론을 뒷받침하기위해 비모수통계방법이 사용되었다. (유의수준 . 10) 밝혀진 결론은 다음과 같다. 1) 내적표상은 피험자와 문제에 따라 각각 달랐다. 초보자들은 모두 한가지 표상을 세 문제에 걸쳐 계속 사용한데 반해, 2명의 전문가는 문제에 따라 다른 표상을 사용하였다. 이러한 표상의 형태에 따라 문제해결결과가 달랐다. 즉,일-에너지 표상형태를 사용한 피험자가 더 나은 결과를 얻는것으로 나타났다. 2) 문제해결방안에 있어서는 전문가들은 세문제에 걸쳐 계속하여 지식-개발 방안을 사용하였으나 초보자들은 문제에 따라 다른 방안들을 동원하였다. 지식-개발 방안을 사용한 경우가 다른 것들에 비해 더 나은 결과를 얻는 것으로 나타났다. 3) 사고 수준검사(하위검사 또는 전체)의 접수와 문제해결과정 변인들-특히 내적표상의 형태, 문제해결방안의 종류, 목표확인 그리고 문제 해결력-간에는 유의미한 관련이 있는 것으로 나타났다. 4) 그외 속도와 가속도 개념의 혼동, 마찰력 개념의 부정확 등이 공통적으로 범하는 실수였다. 본 연구가 과학교육 실제에 주는 함의로는 내적표상, 문제해결방안의 훈련을 통한 문제해결력의 향상을 들 수 있겠으며 이를 위한 세부연구가 실행되어야 할 것이다.
