The purpose of this study wasto analyze the factors that enhance their learning achievement in a fieldtrip environment. For this academic goal, we analyzed a pattern of fieldtrip-related perception and attitudes of 19 science-talented students who participated in the 2007 KESO winter school. As for the perception type, the result of analysis showed that the science-talented students understood a fieldtrip as an experimental inquiry from an inquiry perspective, and that their understanding about a fieldtrip was based on anthropocentrism, positivism and instrumentalism from a science philosophy perspective. Regarding theattitudes type, the result revealed that the purpose of the winter school was mainly to learn knowledge in earth science, and that there was a significant tendency for the participating students to become a future scientist more eagerly than their parents expected. Students' fieldtrip-related academic self-concept was mostly positive while the participants experienced both positive and negative emotions.

The aim of this study was to categorize and analyze the patterns of the observation type in the experiential learning through the science museum for elementary gifted students in science. Ten science-gifted students were included and analyzed in this study and during experiential learning in the science museum, the participants freely expressed their observation of their own languages and all observations and dialogue were recorded. The results are listed below. The cognitive aspect, especially question and response activity without their personal opinion, was the most frequently used item. Among the affective aspects, item for 'recommendation' was often used. In accordance to observation type, most participants overall observed single object independently of time. Also, participants mostly observed objects visually using qualitative method without manipulation. Therefore verbal interaction through question might have a positive effect on frequency and diversity of observation. Project learning, such as particular exhibition hall, exploratory time of concentration by students, or study paper will be capable of creating a effective observation learning in order to induce a variety of observation of science gifted students in the experiential learning through the science museum.

과학 모델은 복잡한 자연현상을 단순화하고 패턴화한 것이다. 따라서 과학 모델은 특정한 알고리즘을 가지며, 과학 모델에 대한 이해는 모델이 갖는 특정한 알고리즘에 대한 이해와 직접적으로 관련되어있다. 본 연구에서는 많은 학생들이 대안 개념을 가지고 있는 산-염기를 주제로 하여, 이 모델이 가지는 알고리즘을 학습하기 위한 프로그램을 설계하고, 알고리즘을 학습 하였을 때 과학 학습에 미치는 효과를 확인하였다. 고등학생 3학년을 대상으로 4차시로 수업을 진행하였으며, 수업의 사전과 사후 검사를 실시하여, 학생들의 모델에 대한 이해를 분석하였다. 수업 결과, 학생들은 모델의 정의와 화학반응 및 화학평형의 정성적인 부분에서는 이해의 향상을 보였으나, 정량적인 부분에는 효과를 보이지 못하였다. 이는 화학이 많은 수의 입자를 고려해야 하는 독특한 과목의 특성에 기인하며, 이를 보완하기 위하여 추후 컴퓨터프로그램을 교육 도구로 사용하는 수업을 통해 후속연구를 진행하고자 한다.

This study developed a field trip program called "Planning a science exhibition" and explored elementary science-gifted students' perceptions of the program and learning experiences influencing them. To this end, 56 elementary science-gifted students in grades 4-6 from in an university-affiliated science-gifted education institute in metropolitan area were selected to participate in the field trip program. After the program, the students answered a survey regarding their perceptions of the program. Additionally, 19 students were selected for group interviews to further explore their survey responses. Results showed that many elementary science-gifted students perceived the program positively in various cognitive and affective aspects. Some students also pointed out certain limitations of the program. Five interconnected learning experiences were identified as influencing the students' perceptions: "experiences fostering creativity", "non-residential camp-type project-based learning experiences", "self-directed learning experiences", "experiences utilizing digital devices", and "collaborative experiences". Educational implications regarding these results were discussed.

This study is a case study examining how research-based 'authentic' science education program contextually facilitates students' learning on NOS as a process. We developed 'Becoming a Scientist' mentor-mentee program and applied it to six Korean 7th graders for 8 months. A mentor, who is also a researcher, provided scaffolding and coaching, and her mentees were to perform the whole process of science research, including selecting the research subject and questions, planning research design, doing experiments, collecting and analysing data, writing research paper, and experiencing poster presentation at an academic conference. The research questions are 1) What would the students experience at every step of their research process?, and 2) Which perceptions would they construct NOS as a process? Data include classroom observations, interview, mentor's journal, and students' learning products. The results show that the mentees have experienced their views of NOS as a process in various ways such as role of research question and purpose, validity of measured value, researcher's subjectivity in interpreting data, experience of making public and peer review, and significance of academic conference. This study has shown that students' actual experience in scientific research enhanced their views about NOS as process without explicit and reflective approaches. We defined 'authenticity' associated with not only with its similarity to what scientists do but to learner's identity as scientific researcher. Based on the situated learning theory, this study sheds light on the necessity of reconsideration about the meaning of authenticity and embodying authentic context in science education for better NOS learning.

The purpose of this paper is to introduce the current studies and research methods about Learning Progressions disseminated to several countries including the U.S. since 2006. It also provides a methodological base to investigate learning progressions in science by introducing a case study of learning progression conducted in Korea. For this study, we described several features of current studies on learning progressions in the U.S., and reported the common ways and sequences employed in examining learning progressions especially with respect to assessment for learning. Learning progressions are descriptions of developmental pathways of learning a topic, in which science knowledge is used in students' engaging in science practices. Each learning progression consists of upper anchor, lower anchor, and intermediate steps that connect both anchors. In investigating a learning progression, researchers usually utilize Wilson's four building blocks of assessment system based on the assessment triangle. This kind of method was also applied in investigating the learning progression for water cycle in this study. We discussed implication and consideration for the future research on learning progressions in science in Korea.

This study aims to develop a field trip program for the Hantan River geopark in Pocheon using Orion's field trip model. The selected learning sites were the Hwajeogyeon and Bidulginang Falls, famous geosites of the Hantan River geopark in Pocheon. The field trip program consisted of six preparatory units, two field trip units, and two summary units. The preparatory stage helped reduce the novelty space considering cognitive, psychological, and geographical factors. In the field trip stage, students acquire concepts linked to learning elements in the curriculum scientifically and encourage interest in science. In the summary stage, students organized the geological phenomena observed in the field and inferred the vicinity of the Pocheon Hantan River region. The field trip program was modified to give enough time for observation activities to increase students' interest in science and to connect concepts with learning elements in the curriculum in the outdoor learning phase to allow students' convergent thinking. Implementing the field trip program raises students' interest and attitude in science.

This study investigated whether science museum field trips over a duration of 7 months would effect student preference and awareness of science museums. 32 eighth and ninth graders were sampled from a middle school in Seoul and asked about their preference, awareness and the effect of the science museum visits both before and after a field trip. Findings showed a preference for science museums which dealt with themes and topics of student interest. After a field trip, student responded that science museums were information providers which yielded opportunity to explore forthcoming science feats, science in everyday life, developmental histories of science and technology, science-related news, social issues, and science rationale. Even though science museums in Korea leave much to be desired in terms of quantity and quality, field trips were positively received by students. This reception and its usefulness implied that expansion publizing and active use of formal/informal education relating to science museum facilities need to be top-priority business.
