Current computer education is difficult to educate basic concepts and principals of the computer science because the 7th curriculum of computer education is focused on the application of software. According to the ACM K-12 report about the computer science education model, current computer education is taking the wrong way and we should put the highly priority on the education of the fundamentals through programming languages for a better computer education oriented to the computer science. This paper introduces a new object-oriented educational programming language "Dolittle". The design principals of Dolittle are simple syntax of Korean, incremental programming, text based programming, aliasing of function, and object-oriented programming. Being applied to middle school classes, we can confirm that Dolittle is easy to learn, and gives rise to high interest and keeps interest through a course, and also is of great practical use in class for programming novice.

In the last few years, there has been a significant growth of interest in how the philosophy of science can be related to science education. Adequate understanding of the philosophy and history of science can promote understanding of the nature of science in teacher and student. The 6th curriculum in Korea has also placed emphasis upon understanding of the nature of science. From this point of view, to ensure effective school science education it is necessary to investigate how teachers and students are understanding the nature of science. To do this 45 secondary science teachers and 191 students of 7 schools in Seoul are administered Nott and Wellington's questionaire(1993). This questionaire is consisted of 24 Likert Scale statements and asks questions on 5 subscales of philosophy of science :Relativism-Positivism, Inductivism-Deductivism, Contextualism-Decontextualism, Instrumentalism-Realism, Thinking science education as a Process or a Content. The results of this study are as follows : 1. Teachers' view of the nature of science was relativism, deductivism, decontextualism and instrumentalism. And they thought process is more important than content in science education. 2. There was no difference in teachers' conceptions on the nature of science according to experience and gender. 3. Students' view of the nature of science was relativism, deductivism, decontextualism and instrumentalism. And they thought process is more important than content in science education. 4. There was no difference in students' conceptions on the nature of science according to schools level(middle vs high) and gender. But, female students exhibited higher score than male students on deductivism(p<.05). 5. Teachers' and students' conception of the nature of science was in agreement with each other.

The photoelectric effect is a representative phenomenon explaining the particle nature of light and is an important theme that led to the transition from classical physics to modern physics. Although the secondary school curriculum deals with the photoelectric effect, teachers and students are often confused with terms because the explanation of the 'light intensity' is different from that of electromagnetic waves. Hence, this study examines how modern physics textbooks explain the intensity of light through photon model. We analyzed the photoelectric effect unit of 10 modern physics textbooks. Results show that there are two different types of representation on 'light intensity.' Especially those two different types were found even within a textbook. Modern physics textbooks do not seem to provide a unified presentation of the light and cautions to describe the photoelectric effect and its interpretation are suggested for teaching light intensity in modern physics.

This study was carried out qualitative study to figure out the process of the perception of creativity conception by kindergarten teachers in Korea. The interviewees are 4 current teachers in kindergarten in Seoul. Data was collected from semi-structured in-depth interview. Collected data were analyzed using Modified Grounded Theory Approach by Kinoshita, a kind of qualitative research method. As a result of data analysis, kindergarten teachers who experts in child education understood key concepts of creativity as unique thinking and rich expression ability. Such concept is mainly acquired at the class in which direct encounter with children is made. Besides, they formed the concept of creativity through reading books and articles, graduate studies and teaching Nuri Curriculum. In the preceding studies on the concept of creativity targeted to elementary and secondary school teachers, they had shared wide concept, but kindergarten teachers shared only some key concepts on creativity. This result would mean that the concept of creativity in the early children education is relatively coherent and such concept and teaching method are relatively well delivered to children at the education field.

This study aimed to analyze the evolution of general ideas concerning the element and the atom. In the scientific viewpoint, the modern idea of the element has been variously revised by the ancient Greeks, Boyle-Lavoisier, and Dalton. The definition of the atom was confused with that of the element from the ancient Greecian era to Lavoisier's era. The definition was also changed by Dalton and Rutherford. An analysis of the definitions of element and atom as presented in science textbooks for secondary school students and in general chemistry textbooks revealed that these definitions from diverse eras are confusing and inadequately explicated. The definition presented in one textbook was contradictory to the definitions in other textbooks. This tendency has been sustained in the textbooks from the 4th to 6th science curriculum. Therefore, we need to clarify the definitions of element and atom in order to help the students gain a better understanding of these scientific concepts.

The opinion, that the history of science should be introduced to science lesson, has been continuously emphasized by a group of people who supported the needs of science and scientific process, nature of science, and the interaction between science and society. When the importance of the integrated science education is emphasized, the history of science is suggested as an effective curriculum for it. To respond to this identified interest, we developed a lesson of the history of science by selecting the contents of the history of science as subject topics of the integrated science and by utilizing the findings of previous studies related to the history of science in science educations. To develop the history of science class as a subject of integrated science, we chose 'the age of the earth' as a unit. After the pilot test of the unit in secondary school students, the possibility of offering the lesson as a regular course was examined with analysis of the students' reactions showing its effectiveness.

In this research, we investigated the support system and professional development in teaching practices of beginning science teachers through instructional consulting. Using open-ended interviews with the participating teachers and group discussions taking place on a regular basis to analyze and compare classes of six beginning teachers, we analyzed beginning teachers' professional development efforts centering around their teaching practices. The group discussion consisted of 6 beginning teachers and another 6 experienced teachers, they discussed and cross-analyzed beginning teachers' 9th lessons on middle school science unit, 'Work and Energy.' The characteristics of beginning science teachers' professional development drawn from this research are: (1) beginning teachers' teaching practices they were taught, (2) lack of reflection on their teaching practices, (3) no guidance for beginning teachers regarding ways to teach, (4) lack of communication between teachers about teaching science, and (5) lack of time for instructional preparation due to other heavy workload. Suggestions for ways to improve and support beginning teachers' professional development are discussed with experienced teachers. Required conditions for an effective induction program are also discussed.

The college of education should support pre-service science teachers to develop various abilities as a teacher, in which the teaching ability is the most fundamental one. This study is the result of a longitudinal research project following the processes that pre-service science teachers develop their teaching ability in a college of education. The data gathered include movie clips of seminar presentation, teaching demonstration, secondary school science experiment, and classes in the practicum. In order to analyze the teaching abilities in various context, a framework was developed. The framework consists of 'content,' 'progress,' and 'verbal/nonverbal' with which the movie clips of 5 pre-service science teachers were analyzed. The teaching abilities of pre-service science teachers showed overall development, that include the understanding of learners and curriculum in the 'content,' the time-management and the interaction with learners in the 'progress,' and the nonverbal behavior in the 'verbal/nonverbal.' The implications were discussed on the education in the college of education, such as the increase of teaching opportunities for pre-service science teachers and the support for those opportunities.

The aim of this study was to research the characteristics of science teachers' thinking related to dissolution and diffusion. For this study, five science teachers who majored in chemistry or chemistry education were selected and interviewed. These teachers have been teaching on average for 2$\sim$6 years. From the study, it was discovered that the science teachers didn't recognize the necessity of sorting out diffusion from dissolution. The teachers divided in various mixing phenomena with diverse criteria. The science teachers had difficulty in sorting out diffusion from dissolution based on solubility and Gibbs' energy. The teachers didn't see the linkage between the contents that were divided into chapters, and didn't find omitted contents themselves in the chapters that introduced applicable principles. During the interviews, the teachers felt the need to understand the principles for understanding phenomena. But they did not have the ability to teach these principles after learning about the principles themselves. Therefore, it is necessary to develop teacher education programs, as well as a science curriculum, that helps in linking the knowledge between natural phenomena and principles.

As the importance of computing technology is emphasized, Korea has revised the educational curriculum to teach SW education compulsory at the elementary and secondary school level. For successful SW education, it is very important not only to require an educational environment and educational materials, but also to obtain the capacity of the teachers who are responsible for SW education. However, due to the lack of research on specifically examining the present state of teachers' SW competencies, there are many deficiencies in establishing a concrete teacher's training and a support plan for SW education. This study is to develop test tools and apply to measure a common sense about a computer, the latest IT technology algorithm design and a programming ability for the purpose of evaluating the SW competency of current teachers. As a result of the study, the understanding of common sense about a computer and the latest IT technology is very high, on the other hand the algorithm design and programming ability were analyzed as low. Therefore, the implications for SW education teacher's training and a process of prospective teachers' training are derived.
