This study primary aim is to investigate students' responses to experimental results which conflict with their preconceptions regarding electrical circuits. Eighty-eight students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit, and sixty-eight students with relevant misconceptions were selected. These students were presented with experimental results obtained by some other experimenter, and asked to interpret these results. The second aim of this study is to explore how students' responses vary according to the type of inquiry-skills required to obtain the result. To do this, two type of experimental results were developed: one obtained by observation and the other obtained by controlling variables. We found that many students doubted results for the simple reason that they conflicted with their preconceptions. They rejected results by mentioning other factors which could have affected the result, or simply by reiterating their preconceptions. This behaviour varied considerably by inquiry-skill type. 41% of students rejected conflictual result obtained by observation, but only 6% of students rejected results obtained by controlling variables.

This study gives opportunity for investigating how student teachers view the teaching profession and how they transfer their pedagogical knowledge into practice. The aim of the study is to investigate the teaching skills student teachers gained in the assessment of micro teaching of their peers. The participants are 30 mathematics student teachers enrolled in the teacher training program in a state university. Document analysis and semi-structured interviews are the research instruments and inferential & descriptive statistics are used for the data analysis. The findings suggest that the qualitative and quantitative peer assessments of student teachers were graded differently which results from the difference of perceptions about teaching and different conceptualizations of the teaching qualifications.

인성교육의 의미와 방향은 인간됨의 형성이라는 교육의 본질적 차원에서 이해하고 접근할 수 있어야 할 것이다. 이러한 의미의 인성교육을 위한 최선의 방책은 가르치는 교사의 인간형성에서 시작할 수 있다고 생각한다. 왜냐하면 교사는 학생들의 인성형성에 핵심 역할을 하기 때문이다. 따라서 본 연구는 인성교육자로서 교사 인성의 중요성과 교사교육에 인간다운 인간형성을 목적으로 하는 교양교육이 요청됨을 논의하고, 교양적 교사교육의 가능성을 탐색하고자 한다. 이상의 연구 목적을 위해 II장에서는 가르침의 도덕적 차원과 인성교육자로서 교사 역할의 중요성을 논의한다. III장에서는 교사의 인성교육 현황을 살펴보고, 교사의 인성형성을 강조하기 위해 교양적 교사교육이 요청됨을 논의할 것이다. 교양적 교사교육이란 인간다운 인간형성을 위해 전인성, 전환성, 비판적 성찰을 강조하는 교양교육의 특성을 접목한 교사교육을 뜻한다. IV장에서는 교양적 교사교육의 가능성을 탐색할 것이다. 구체적으로 교사교육에서 직업교육적 측면과 교양교육적 측면의 양립가능성을 논의하고, 실제 교사교육에서 교양교육의 특성을 반영할 수 있는 방안을 교육목적, 교육내용, 교수방법 면에서 탐색할 것이다.

The purpose of this paper was to analyze the role of illustrations in elementary textbooks (3~4 grade) of the 2009 revised curriculum of science education in Korea from point of view of aim of science by applying the criteria of 5E inquiry process model for reflecting core aim of the science education. The subjects of the paper was the 105 illustrations in the earth-science domain of elementary science textbooks (3~4 grade) of the 2009 revised curriculum of science education in Korea. The analysis criterion was of two categories, the function of illustration and the role of illustration. the function of illustration was divided into three subcategories such as Exclusiveness type, correspondence type and supplementary type. The role of illustration was divide into five subcategories such as Engagement, Exploration, Explanation, Elaboration and Evaluation. According to results of the illustration analysis are as follows: the result of the function of illustration are exclusiveness type 39, correspondence type 36 and supplementary type 30, the important of point to note is that there are a lot of exclusiveness type considerably. compared with other subjects, this fact indicate character of illustration of the only science textbook. The result of the role of illustration are Engagement 14, exploration 64, explanation 25, elaboration 2 and evaluation 0. This data indicate main role of illustrations in earth-science domain is to help the students to be able to observe and explore. Cross-analysis of the function and role was a significant difference. Role of illustration was evenly distributed within Exclusiveness type on the other hand, the role of illustrations was mainly exploration and explanation in correspondence and supplementary type. Especially, illustration of exploration was mainly correspondence type.

In the Republic of Korea, mathematics has always been a major blame for huge private expenditures on so-called "private education," which consists of private tutoring and lessons at "private academies of extra curricula." The private spending on out-of-school education often exceeded public expenditures on schools. In 1997, South Korean Ministry of Education reformed curriculum of mathematics along with other subjects to ease the burden of private education. The aim of this curriculum change was to put a boost on individual students' interests, affections and other attributes toward school mathematics. The essential distinctiveness of the new curriculum of mathematics compared with the previous one is as follows: 1. The implementation of so-called "differentiated curriculum" for grades 1-10. 2. 30% reduction of contents in mathematics and the reconciliation of contents. 3. Elective subjects for mathematics for grades 11 and 12. 4. More uses of technology in mathematics teaching. Firstly, we examine the background of the curriculum reform and analyze the new curriculum according to awareness of educational administrators, teaching environments of schools and readiness of mathematics teachers. Then we find out what kinds of problems it has and look for some suggestions for remedies.

Children interest themselves in all different toys they see, before beginning to speak. The psychological reasons for children′s interest in toys have been investigated for a long time. Thus many scientists have studied on the question "what is game？", but they have not reached a consensus yet. Such contradiction may be dependent upon different points of view of the researchers about game. Besides, the view of game of a child and an adult is different too. According to an adult game is a rebirth and escape from monotony. For child it is a work. The aim of this study is to make mathematics regarding a mass of abstract concepts for the students of grade 1-3 of primary school in the concrete operations period, more attractive with the help of educational and instructional games, and to contribute to student′s developing. The capability of thinking and producing by changing abstract concepts into concrete ones.
