Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

Instructional objectives clearly show what teachers should teach in the class and how they lead the class, focusing on a certain activity for their students in the class. Clear instructional objectives are a prerequisite for teachers to accomplish effectively their curriculum. The revised Bloom's taxonomy table of educational objectives has been introduced in 50 years since the publication of his original taxonomy table in 1956. Bloom's revised taxonomy table of educational objectives has two-dimensions, the "cognitive process" dimension and the "knowledge" dimension, and it classifies class objectives more elaborately and clearly. This study was designed to classify instructional objectives stated in elementary science guidebooks for teachers into Bloom's revised taxonomy table, and see how the objectives of elementary science classes were categorized by grade level and areas. In addition, this study examined how the objectives of elementary science classes by study area were classified into the new taxonomy table. This study classified 618 elementary science instructional objectives of third- to sixth-grade science guidebooks for teachers into Bloom's revised taxonomy table. The results showed that the objectives of elementary science classes emphasized disproportionately some of the knowledge and cognitive process dimensions. In the area of subjects while the percentages of factual knowledge were very high, those of meta-cognitive knowledge were low.

In this study, the effects of STAD cooperative learning strategy on students' achievement, learning motivation, perceptions of learning environment, and perceived classroom goal structure were investigated in terms of students' collectivism level. Two classes (64 students) from an elementary school were respectively assigned to a control group and a treatment group. A individualism-collectivism test, a learning motivation test, a perceptions of learning environment test, and a perceived classroom goal structure test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. After instruction, an achievement test, the learning motivation test, the perceptions of learning environment test, and the perceived classroom goal structure test were administered. The results indicated that the students of the treatment group significantly outperformed those of the control group in the achievement test. There was a significant treatment-aptitude interaction effect in the scores of the attention subcategory of the learning motivation. In the perceptions of learning environment, the score of the treatment group was significantly higher than the control group in the cohesiveness subcategory, whereas the score of the treatment group was significantly lower than their counterpart in the competitiveness subcategory. It was also found that the score of the treatment group was significantly higher than the control group in the performance subcategory of the perceived classroom goal structure.

This study was intended to explore the changes in teaching methods when freedom to choose curriculum, instruction, and evaluation methods is allowed and when 'free semesters' are free from entrance examination for high school. For this question, we analyzed free semester education plans of eight sample schools and interviewed 33 teachers and students respectively. The results were as follows. Firstly, all schools planned to use teaching methods for meaningful learning, although they are limited to those exemplified in guidelines for free semester. Secondarily, teaching methods adopted for free semester were characterized as activities enhancing student participation. Thirdly, teaching methods such as career exploration, scientific experimentation, cooperative learning, flipped learning, interdisciplinary learning were used only a couple of times in a semester. Changes in teaching methods were referred to enhance students' interest, confidence, self-regulation, creativity, problem-solving and cooperative learning.

In this study, we investigated the characteristics in the processes of generating analogy for lessons by pre-service science teachers. Eight pre-service teachers at a college of education in Seoul participated in this study. After the workshop of analogy in science education, they generated analogies for lessons. In order to investigate thought processes deeply, we used the think-aloud method and also conducted semi-structured interviews after their activities. Worksheets written by the pre-service teachers were collected. Their activities and interviews were recorded and videotaped. The characteristics in the processes of generating analogy were analyzed in the perspectives of student, analog, and concept. The analyses of the results revealed that they generated analogies to correct students' misconceptions and also considered misconceptions that could be caused by their analogies. They generated analogies using sources with which students are familiar. They also generated concrete and everyday analogies rather than abstract and artificial analogies. There were some cases where they did not clearly grasp the target concepts and expressed the concepts which were not covered in the unit. On the bases of the results, we suggest some educational implications for pre-service science teacher education.

In this study, we analyzed contextualized NOS lessons planned by preservice teachers from the perspectives of PCK. Eight preservice teachers who had completed all of the curriculum at the College of Education located in Seoul participated in the study. CoRe and teaching and learning guidance were collected. Interviews were also conducted. We used analytical induction to analyze the collected data. The analyses of the results revealed that the NOS learning goals selected by the preservice teachers were different depending on the context of the NOS lessons. In addition, the preservice teachers were unable to sufficiently explain the value of learning NOS. All of the preservice teachers were worried that their students would not understand NOS properly, and they faced various difficulties in dealing with NOS and science content. They thought that if their students conducted experiments, errors could cause problems for students learning NOS. Meanwhile, they guessed their students' preconceptions and misconceptions of NOS based on their experience. The preservice teachers also thought that their students' concept of science and cognitive development stage would affect their NOS learning. Although the preservice teachers used various strategies to teach NOS, NOS was often not explicitly addressed. Also, they were reluctant to evaluate NOS in lessons. Based on the above results, educational implications for preservice teacher education were proposed.

The present study was carried out to investigate the actual condition of the evaluation of science learning in the secondary school, and to develop the basic data for the improvement of the science learning assessment. Various questions for three evaluative domains were asked to 51 science teachers with the questionnaire during the in-service training course for certificate on summer in 1998. The cognition of the table of specification appeared high as 98% responses to the questionnaire, but the teachers' ability to distinguish behavioral elements was low as 47% responses. The evaluative rate of three domains for knowledge, skill and attitude appeared as 45%, 35% and 20% evaluation in both diagnostic and formative evaluation and 40%, 40% and 20% evaluation in summative evaluation. The evaluation of process skill appeared a tendency depending on laboratory reports as 61%, and was higher rather than in the formative evaluation or summative evaluation. In the evaluation of attitude domain, about a half of teachers answered that they evaluated the domain with laboratory reports as 43%, and some teachers evaluated the domain with teacher's observation as 33%. Also there were a few teachers who did not evaluate the attitude domain as 8%. The rate for the elements of the process skill appeared 86% responses in the interpretation of data, 31% in the observative ability, 18% in the predictive ability, 14% in the classified ability, 12% in the measuring and data-investigating ability, 4% in the discussion ability, and 2% in the investigating ability. We could find out that many teachers had given higher rate in the evaluation of process skill and attitude rather than before the present study, therefore there was more improvement in the evaluation for process skill and attitude domain after the 6th curriculum.

과학영재교육의 중요한 목표중의 하나는 과학영재들의 과학에 대한 태도를 긍정적으로 변화시키는 것이다. 특히 태도와 같은 정의적 특성은 지적 특성에 비하여 후천적이고, 학습에 의해서 변화될 가능성이 크기 때문에(Marsh, 1990) 교육적으로 중요한 의미를 가지며 학생들이 성장하여 과학에 관련된 직업이나 활동을 하는 데 매우 중요한 역할을 한다(Oliver, W Hill, Pettus, W. C. and Hedin, B. A 1990). Anderson(1981)은 과학에서의 정의적 영역을 흥미, 태도, 가치, 통제의 소재, 학문적 자아개념, 불안, 선호 등의 7가지 영역으로 나누고 이 중에서 불안요인을 학업성취 및 태도에 가장 강하게 영향을 주는 요인으로 구분한 바 있다. 이처럼 과학 관련 태도나 과학 불안도는 학생들의 과학관련 활동이나 성취에 중요한 요인이 되고 있으나 이와 관련된 연구는 극히 미미하다. 지금까지의 태도 및 불안도에 관한 연구들은 일반학생들을 대상으로 하고 있으며 과학영재들을 대상으로 한 연구는 전혀 이루어지지 않았다. 따라서 본 연구는 과학영재교육원에 다니는 194명의 과학영재들을 대상으로 하여 과학영재 수업을 받은 후 과학 관련 태도와 과학 불안도가 변하는지, 과학 관련 태도와 과학 불안도는 어떠한 상관이 있는지, 그리고 남$\square$녀 집단의 차이가 있는지를 영재수업을 받기 전과 후의 검사를 통하여 알아보았다. 본 연구에서는 과학영재들의 과학 관켠 태도를 측정하기 위해‘고등학생을 위한 과학 관련 태도’검사를 사용하였다. 이 검사는 Fraser(1981)가 개발한‘TOSRA’(Test of Science-Related Attitudes)와 Munby(1983)의‘태도 측정 도구 조사’에서 문항 선정이 이루어졌다. 적절한 단어 및 어휘, 일부 문항들의 부적절한 환경 상황 등을 고려하여 40 문항 중 21문항을 수정하거나 삭제하고 문항내적 상관이 낮은 4문항을 제거하여 최종 30문항을 제시하였다(고유곤, 1996). 이 검사의 문항 내적 신뢰도 $\alpha$ 는 0.9 이었다. 검사 문항은 4개 범주과학에 대한 태도, 과학의 사회적 의미, 과학 교과에 대한 태도, 과학적 태도 등과 각 범주의 하위 문항으로 되어 있다 과학 불안도 측정 검사 도구는 중$\square$고등학생들의 과학불안도 측정을 위해 김범기(1993)가 개발한 것을 사용하였다.

The purpose of this study was to explore science teacher's epistemological understanding of science and science teaching and learning, from the perspective of inquiry as the process of scientific knowledge building. Three science teachers participated in this study. The data were collected from individual in-depth interviews and classroom videotaping. The results show a case involving coherent and consistent data. It showed that the teacher's epistemological understanding of science and science teaching and learning consisted of five categories: scientists doing science with scientific thinking; scientific thinking as the process of knowing; science learner in the learning process of scientific thinking; science teacher as a man/woman with good understandings of science; and teaching and learning as the process of knowing science. Based on the results, discussions and implications about science education and science teacher education were presented.

This study aimed to analyze the appropriateness of chemistry teaching-learning programs for the gifted in science in middle school gifted classes and to propose improvements. For this study, 5 chemistry teaching-learning 4-6 hour programs developed for science gifted classes by Korea Education Development Institute (KEDI) and 3 chemistry teaching-learning programs developed for science gifted classes by three middle schools in K province were selected. A standard model for gifted education programs was used as tool for analyzing the program targets, program contents, teaching-learning methods, and assessment items. The results showed that all chemistry teaching-learning programs for the gifted in science presented well attainable objectives in the program targets. However, most program targets did not offer differentiated objectives from the general education. Program contents of KEDI stresses intensified education, and also presented a high ratio of sub-elements of creativity, which can enhance gifted creativity. On the other hand, program contents developed by three middle schools focused on acceleration in advancement, and presented low ratio of creativity sub-elements, which could be insufficient in enhancing gifted creativity. Differentiated and personalized, integrated science and interscience, updated research contents were hardly found in programs developed by KEDI and three middle schools. However, teaching-learning methods were composed to fit the learning objectives in the teaching process and the procedures, and were made to self-directed learning. There were no assessment for the feedback after class. Therefore, teaching-learning programs for the gifted in science should be developed further in order to fulfill the objectives of gifted education and gifted characteristics. Also, it is necessary to construct infrastructure to carry out the developed teaching-learning programs.
