This article discusses and reviews the mathematics education of Herbart who had clarified the nature of the scientific education and established the systematic study of pedagogy for the first time. We are mainly investigated the "Pestalozzi's Idea of an ABC of Sense-Perception Investigated and Scientifically Carried out as a Cycle of Preliminary Exercise in the Application of Forms" that proposed intuitive geometric education that embodied his theory on education. Based on this, We discusses the educational implications-the purpose and methods of mathematics education and so on.

In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.

This study investigated the interactions among the PCK components of pre-service secondary chemistry teachers considered in the processes of making written test items individually and in small groups. The processes of making written test items individually for 8 pre-service teachers was studied through the think-aloud method. The analysis of the results revealed that the 'assessment in science education' of the five PCK components was most frequently used in making test items. 'Curriculum for science education,' 'subject matter knowledge,' and 'students' were also frequently used although fewer than the previous component. However, 'instructional strategies and instruction for science education' was hardly used. The integrations between two or three components with various types were frequently found. However, integrations among four to five components were not found. The processes of making written test items in two small groups consisting of four pre-service teachers were observed. The analysis of the results revealed that the PCK components used in small groups were similar to those in the individual processes. However, 'curriculum for science education' was less frequently used, and the numbers of subcategories used at a relatively high frequency increased from other four components in small groups. In the aspects of integration, the proportion of the integrations between two components decreased and that for three components increased compared with those in the individual processes. The integrations among four or five components were also newly found. However, the integrations of 'curriculum for science education' with the other components were less frequently found. The integrations of 'instructional strategies and instruction for science education' with other components were still hardly found.

This study attempted to investigate users' information needs in an educational research library, which delivers web-based digital reference services to library users, by analyzing reference questions asked by remote users. A total of 242 questions from two electronic bulletin boards was examined in terms of 6 types of questions asked and 23 subareas of education. The study found that 56.1% of reference questions on the library bulletin board were pure reference questions in curriculum, textbooks and teaching & instruction. Suggestions for effective use of digital reference services were made: easy access to menu services, use of web forms, development of digital reference systems providing search functions and response functions.

This study investigated the influence of paired think-aloud problem solving on interactions among the pedagogical content knowledge (PCK) components considered in the processes of making written test items by pre-service chemistry teachers. The processes of making written test items using paired think-aloud problem solving in four small groups consisting of two pre-service chemistry teachers were recorded and transcribed. The analysis of the results revealed that the 'assessment in science education' of the five PCK components, regardless of the roles (solver or listener), was most frequently used in making written test items. 'Subject matter knowledge' and 'students' were also frequently used although less than the previous component. However, 'curriculum for science education' and 'instructional strategies and instruction for science education' was a little used. In the aspects of integration, the integrations between two or three components of various types were frequently found. The integrations among four or five components were also slightly found. However, the integrations of 'curriculum for science education' with the other components were less frequently found. The integrations of 'instructional strategies and instruction for science education' with other components were hardly found. The usefulness, limitations, and effective use of paired think-aloud problem solving as a strategy improving competency to make written test items and the PCK of pre-service teachers were discussed on the basis of the results.

교육학의 질적 연구는 문헌 연구, 면담 연구, 비참여 관찰 연구, 참여 관찰 연구로 분류한다. 문헌연구에는 내용분석, 철학적 연구, 역사학적 연구, 문학적 비평이 들어가고, 면담연구에는 구술사, 전기, 탐문(探問) 저널리즘 등이 포함되고, 비참여 관찰연구에는 전문적 감정(鑑定), 인간의 종적 특성 연구, 관찰자 연구, 비개입적 행동 연구 등이 포함된다. 마지막으로 참여 관찰연구는 일반적 현장연구, 문화 기술적 연구가 포함된다. 질적 연구는 사람, 사물, 현상의 범주화나 수량화가 가해지기 이전의 상태, 즉 '있는 그대로'의 상태에 최대한 접근하는 방법으로써, 고정관념을 깨고 기존의 이론을 최대한 유보한 채 연구에 임하는 것으로 최근에 발달한 인문사회과학적 연구방법이다. 질적 인식이 자연언어에 주로 의존하는 데 비해 양적 인식은 인공언어에 많이 의존한다. 수식과 도형, 부호등은 대표적인 인공언어이다. 모든 사물이 질과 양의 속성을 다 가지고 있듯이 모든 연구는 질적 과정과 양적 과정을 다 포함하고 있다. 질적이냐, 양적이냐 하는 구분은 연구방법론의 문제인데 연구방법론은 연구논리와 연구기법을 포함한다. 본 연구는 인공언어인 수와 식에만 익숙한 수학교육에서, 질적 연구가 왜 필요한지, 어떤 특성이 있는지 논의함으로써 수학교육의 새로운 방법론을 제시하고자 한다.

The teacher appointment examination is consisted of a written test, an interview, a demonstration of teaching practices, one's academic record etc. The primary written test(full credit of 100) consists of multiple-choice test of general pedagogy(30%) and constructed response test of science(70%). The science test consists of science education($20{\sim}30%$) and science content($70{\sim}80%$). Five science exams were implemented for appointing general science, physics, chemistry, biology and earth science teachers in 2002 and 2003. The credits alloted to science education domain decreased from $25.7{\sim}30%$ in 2002 to $24.3{\sim}25.7%$ in 2003. The percentage of correct answer was similar between science education and science content domain in 2002, but the percentage of correct answer in science education domain(70.2%) was 29.8% higher than that of science content domain in 2003. Earth science exam almost reached the target mean score of 60 but the other four exams showed the mean scores ranging from 45.0 to 52.7 in 2002 and from 40.1 to 49.6 in 2003. The percentage of high difficulty items(p<40%) was 41.2% in physics and chemistry in 2002, 50% in physics and chemistry, and 45% in biology in 2003. Seventy eight percent of the items showed fairly high discrimination index(r>.30). In addition, the reliabilities of 5 tests were from .79 to .88. In conclusion, it is recommended that the credits alloted to science education domain should be increased up to 30%, and exam difficulties should be lowered to a proper level by making science content items easier.

In order to foster talented people needed for the 4th Industrial Revolution, learner-centered classes that meet the characteristics and needs of students are needed. In particular, the learner-centered student-active class is more meaningful for gifted students who have diverse needs and interests. In order to meet these demands, this study developed a learner-centered science gifted education teaching-learning model based on flipped learning, and analyzed various results revealed after applying the developed program to the gifted class. Based on the results, we proposed a plan for more efficient operation of future learner-centered science gifted education programs.
