본 연구는 비판과학 관점에서 행동의 개념을 분석하고, 교사교육 측면에서 가정과 교사 행동주체성을 탐색하고자 하였으며, 다음과 같은 내용을 함축하고 있다. 첫째, 행동의 개념은 인간이 자신의 의도를 포함하는 활동이며, 설정된 목적과 결정에 도달하려는 고유한 정체성을 드러낼 수 있는 능력으로 공적 영역에서 상호의미에 의해 파악될 수 있다. 둘째, 교사 행위주체성은 교사가 가진 전문적인 경험과 문화적·구조적 측면에서 영향을 받고 있으며, 개인과 공동체의 자기주도적이고 협력적 관계를 촉진할 수 있는 환경을 만들어 나갈 수 있다. 가정과 교사는 행위주체성이 발휘되는 상황과 결과에 대한 성찰을 통해 이성적으로 판단하여 숙고하고 행동할 수 있어야 할 것이다. 셋째, 가정과 교사는 행위주체성을 바탕으로 가정과 교육의 가치와 역할, 목적의식에 대해 비판적으로 성찰하고 사유할 수 있다. 교사의 행위주체성 자체는 완성되는 것이라기보다는 이루려고 하는 과정이 중요하며, 교사 서로 간의 지각된 상호이해를 통해 지속성을 갖고 발전해나갈 수 있다. 따라서 가정과 교사 행위주체성의 개념화는 교사의 행동에서 드러나는 실천을 이해하려는 것이며, 이는 전문적 지식과 경험을 공유하는 상호주체적 환경조성을 통해 교사의 사고와 성찰을 강화하는 기제로 작용할 수 있기에 학교 현장의 환경적 지원이 요구된다.

We investigated the effect of Science Writing Heuristic (SWH) on elementary students' concept formation and their retention. Also we explored the interaction effect of those with scientific attitudes. We developed mirrors/lenses lessons incorporating SWH. An experimental group of fifth grade students (n=25) had been instructed with SWH lessons for six periods while a control group (n=25) taught according to the normal science lessons based on the Korean national curriculum using teacher's guides published by the Ministry of Education. Results of pre- and post-test of understanding the concept of mirrors and lenses showed a positive impact of SWH on both male and female students. However, the retention effect after post-test revealed that SWH only had an effect on female students' scientific attitudes. SWH, therefore, could be an effective teaching approach especially on concept formation, retention effects by fostering female students' scientific attitudes.

Knowledge is composed through the interaction between the concept structure already held by students and their experience, and learning can be said to be the active process of solving the cognitive conflict caused by this interaction. Therefore, this study consists in showing the effective learning method and finding out the elements which the teacher has to own, through examining several forms of pre-conception or mis-conception of the inertia, the force-equilibrium, the action and reaction, the heat, and the electric current, and then finding out their solution and studying student's change in science concepts. For this study, the types of concept on the five above-mentioned materials which students have were examined through the concept-classifying question paper, and the classes to which the class mode for the change of concepts applied, were practised in each different classroom by each different instructor - a professor, a scientist, a teacher, and two students, respectively. And the effect of the teaching strategy based on these classes, and each different instructor' influence on the change of concept in students. were examined. The result of my study is as follows; 1. Students have various types of pre-conception which are different from science concept, and these types of pre-conception tend to last even after learning in class. 2. The thoughts on the correct science concept of the high school third-grade students who learned the physics in the traditional teaching method, and the second grade students who don't learn the physics yet, were nearly equal those of the second grade students by receiving the physics class through the cognitive conflict course were greatly changed especially that students showed the distinct change on mechanics and electric current. 3. Students didn't show the remarkable change of the science concept on the five materials in the four kinds of experimental classes by each different instructor but in the part of mechanics, there was the distinct change between the class by professor and those by the students. This was due to the difference of the authority and the attitude of the concept demonstrator. 1) The authority, the kind attitude, and the responsibility of the expert played an important role in the correct concept-formation of mechanics part - especially in the case of the mis-conception caused by the intuitive belief. 2) In the class by instructor with the democratic teaching method, the change of concept took place more easily, because in his class students could discuss the subject freely, so that they might experience the thought course to give them the confidence on the science concept.

The purpose of this study is find out the correlation of level of knowledge of pre-service elementary teacher with space perception ability on 'Earth and Space' of elementary science. During the second semester of 2013, for 15 weeks, the classes were conducted for 3 hours per week and we find out knowledge Understanding degree and select terms offered by 5th grade science courses 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section and measured space perception ability degree of pre-service elementary school teacher with a questionnaire. We analyzed the correlation of understanding level of knowledge in the field of astronomy of pre-service elementary school teacher with space perception ability. The results of the study are presented as follows. First, pre-service elementary school teacher showed a low level of knowledge understanding as it goes the upper grades about upper concept in 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section' of astronomy area of elementary science 'Earth and space sector'. The pre-service elementary school teachers needs to acquire knowledge of astronomy area in elementary school curriculum. Second, pre-service elementary school teacher showed that there are differences individually in 'finding solid body' of sub-element of space perception ability. This shows that 'finding solid body' factor is associated with space perception ability. Third, in the section of 'The earth and the Universe' for elementary education, 'Reflection' and 'Finding solid body' which are low-level components of space perception ability were verified that have a corelationship with general grades in the astronomy conception test.

The purpose of this study is to look into self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class, and investigate correlations among them. For this study, the survey was carried out on 338 elementary school teachers, and the interview was conducted with 5 of them. The results of this study are as follows; Self-concept of elementary school teachers about inquiry instruction in science class was more positive than usual. And the teachers who were male, older and majored in science education showed more affirmative self-concept about inquiry instruction in science class. Teaching anxiety of elementary school teachers about inquiry instruction in science class was less than usual. And the teachers who were male, older and majored in science education showed less teaching anxiety about inquiry instruction in science class. The correlation of self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class was an negative interrelation. This presents that the teachers, who have more positive self-concept about inquiry instruction in science class, have less teaching anxiety than those who have more negative one. Consequently, teacher training and retraining programs should be developed and conducted by grasping teachers' self-concept and their anxiety, to reduce anxiety about inquiry instruction in science class.

The purpose of the study was to examine early childhood teachers' content knowledge on green growth education. The subjects, 45 early childhood teachers, were asked to draw concept maps about early childhood green growth education. Their concept maps were analyzed in terms of superordinate and subordinate concepts by contents and frequencies. The results showed that early childhood teachers used 182 superordinate and 1,292 subordinate concepts in the concept map of green growth education for young children. Although early childhood teachers had a wealth of content knowledge on green growth education as proposed by the Ministry of Education, their knowledge was disproportionate to some areas and sub-areas of green growth education. These results implied the needs of developing teacher education programs for early childhood green growth education.
