Teacher guidebooks are practical and commonly used resources for teachers to deliver the goals and contents of science curriculum in classroom teaching. Thus, the alignment of teacher guidebooks and science curriculum could be critical to undertake the effectiveness of curriculum implication in science classrooms. This study is to investigate how the learning objectives of science curriculum are implicated in teacher guidebooks by analyzing the dimensions of knowledge and cognitive process in learning objectives in both documents. Grade 3~4 learning objectives (82 objectives in the curriculum, 459 in the teacher guidebook, 541 in total) in 2009 Revised science curriculum and teacher guidebooks were coded and analyzed based on the Revised Bloom's Taxonomy. The analysis focused on how the knowledge dimensions and cognitive processes of the curriculum were emphasized and restructured in the teacher guidebooks to examine the coalition between the two important documents. The study found: 1) the learning objectives in Grade 3~4 in both documents were skewed to certain knowledge dimension (conceptual) and cognitive process (understand); 2) there was a high coalition between unit objectives and lesson objectives in the teacher guidebooks, however, relatively low coalition between the curriculum and the teacher guidebooks; and 3) learning objectives in the curriculum were delivered in teacher guidebooks in various patterns (similar, detailed, additional, in portion, and the same), and 'detailed' and 'additional' were frequently shown. There also appeared new objectives in the teacher guidebooks, which were not present in the curriculum. The findings in this study could provide some suggestions to the current project of developing 2015 Science Curriculum in regard to understanding the dimensions of knowledge and cognitive process of learning objectives and their alignments with textbooks and teacher guidebooks.

There have been gradually a few studies on Noticing in the domestic and international area. For the purpose of increasing the concern on teacher noticing and pursuing the affluent studies on the noticing, this study tried to explore and understand the background, the meaning, and the properties of the teacher noticing while summing up the views of the various researchers. As a result, the teacher noticing could be defined as a cognitive process which is focused on mathematical objects, students' mathematical thinking, students' emotions, teaching strategies, classroom environment and interprets them to determine how to react. From this, noticing might be cognitive process which is a combined form of the objects and cognitive behavior, while the objects whom teachers notice covers up the mathematical objects and the teaching objects. Eventually, this study expects to serve as a basis to foster the in-depth understanding of teacher noticing and to derive the follow-up studies.

The purpose of this study is to analyze lesson plans from third to sixth grades of science and to find out teaching strategies in respects of learning functions provided by preservice elementary teachers in education university. On the whole, to control students' learning process preservice teachers used more shared-regulation strategy than strong teacher-regulation one. Teaching activities for regulative learning function were most used in strategy of strong teacher-regulation, and in strategy of shared-regulation those for cognitive learning functions were most used. But teaching activities for affective learning functions were used a little considered in both teaching strategies. In introduction step of instruction, affective and regulative learning functions were more instructed by strong teacher-regulation strategy and cognitive learning functions were more instructed by shared-regulation strategy. The affective, cognitive, and regulative learning functions were largely planned by shared-regulation teaching strategy in development. The regulative learning functions were planned by strong teacher-regulation strategy than by shared-regulation strategy and affective learning functions were considered a little bit in consolidation. There was a tendency that strong teacherregulation strategy was increased in lessons for fifth and sixth grade.

The purpose of this study was to development a model of problem solving instruction for improving practical skill-competence in technical high school. For the study, various literature researches were reviewed intensively about problem solving process, laboratory instruction's approaches and learning principals. The problem solving instruction process was composed with identifying problems, generating alternative solutions, investigation and research, choosing a solution, acting on a plan, modeling of problem solving, testing and evaluating, redesigning and improving. The skills schema combines a four domain of skilled activity, that is, cognitive skills, psychomotor skills, reactive skills and interactive skills. The problem solving instruction was composed with five major learning systems-emotional, social, cognitive, physical, and reflective-that can be used extensively as generic lesson plashing. The teacher serves as a coach or guide for student learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem with think aloud, assume responsibility for their learning and move from teacher-centered to student-centered education.

The purpose of this study was to investigate the process and the effect of pre-service teacher's scaffolding in environmental camp program about global climate change. For this study, developed the environmental camp program based pre-service teacher's scaffolding and applied to 78 $5^{th}$ students. We analyzed the role of pre-service teacher in the process of scaffolding. In the result, the pre-service teachers conducted cognitive scaffolding like as "Focus", "Hint", "Tell or Summarize" and "Technical Help". They carried out the emotional scaffolding like as "Create Cheerful Atmosphere", "Encourage", and "Help in Living". Teaching and learning about global climate change, the theme of the camp, was regarded uncertain and complex. So, pre-service teacher's scaffolding was effective to promote environmental literacy about climate change of primary students (<0.05). The student teachers understanded the characteristics of the children through emotionally close relationships. The primary students were learned easier about global climate change through cognitive and emotional scaffolding. They experienced environmental practice with communal living in camp.

The purpose of this study was to determine the effects of verbal analogy activities on science achievement and science attitude of elementary students. Students consolidated lessons by making short sentences with core words that a teacher gave for scaffolding instruction. Many researches about analogies have been conducted in science education. However, most of them considered analogy as learning tools, whereas this research considers analogy as a cognitive process. To see the effects of verbal analogy activities, two groups were selected from 6th grade elementary school students; one was an experimental group working with the student-generated verbal analogy and the other was a control group with teacher-centered and textbook-centered activities. Science achievement, scientific attitudes, attitudes toward science and retention were tested after the treated lessons.

The purpose of this study was to identify the interaction patterns in distance only mode e-Learning. In order to investigate this study, messages shown in the electronic notice board were analyzed to see how interaction occurs between teacher and learner or learner and learner under the e-learning of cyber university. To analyze messages was applied according to the framework by Henri's contents analysis model. As a result of contents analysis on electronic board, the participative dimension was 399 messages. A learner put on 7~8 messages a day. The number of messages was low compared to the number of learners, but the number of inquiries was about 140. That means that each learner contacts and checks messages at least once a day. The meaning dimension was 600 units. The main interaction patterns were Interactive-social-cognitive-metacognitive. This means that e-Learning in distance only mode leads a positive attitude of learners as a self-directed learning, and needs teacher's well-structured instructional strategies for increasing interaction. In conclusion, social dimension and interactive dimension of messages support learners psychologically in the process of learning though they directly guide learning under the circumstances of e-learning lacking face-to-face element. It can be interpreted that the teacher's role is significantly important in order to attract learners' positive participation and cognitive and meta-cognitive dimension of messages and activities

본 연구는 수학 교사와 고등학생을 대상으로 그래프로부터 의미를 어떻게 구성하고 그 과정에서 그래프 해석의 요소들이 어떻게 상호작용 하는지를 분석하여, 그래프 교수학습에서 고려해야 할 점을 제안하는 것을 목적으로 한다. 분석결과, 교사와 학생 모두 그래프에서 의미를 구성하는 것에서 많은 어려움을 겪었고, 의미를 구성할 때 포개어지는 관계망의 형태로 구성해갔다. 또한 의미를 구성하는 과정에서 인지적 맥락적 정서적인 요소가 서로 상호작용하여 해석체를 구성해갔다. 하지만 이 과정에서 교사는 그래프에 질적인 접근방법으로 인지적인 요소에 주로 초점을 두었던 반면에, 학생은 양적인 접근방법으로 인지적인 요소와 함께 맥락적인 요소도 고려하여 자신이 구성한 해석체를 정당화시키고 이를 기반으로 의미를 구성해갔다. 본 연구는 이런 결과를 기반으로 그래프 교수학습에서 고려해야 할 점을 3가지로 제안하였다.

인쇄매체를 기반으로 한 전통적인 정보의 생산과 유통과정은 컴퓨터와 정보통신기술의 발달로 인하여 전자매체로 급격하게 변화하고 있다. 출판 과정의 전자화, 고밀도 대용량 기록매체의 등장, 데이터 통신 기술의 발달로 인하여 2차 정보뿐만 아니라 원문 자체를 수록한 전자문헌이 급증하고 있으며, 활용범위가 넓어지고 있다. 그러나, 전자문헌을 탐색하고, 디스플레이 하거나 브라우징 할 수 있는 현행 내비게이션 도구는 현재 전자문헌의 장점을 극대화하지 못한채 물리적인 접근에 치중하고 있으며, 이용자의 인지적 접근 과정 즉, 전반적인 정보수용행위를 반영하지 못하고 있다. 따라서 본고에서는 이용자의 인지적 접근과정을 내비게이션 도구에 적용한다면 이용자의 인지적 부담을 줄이고, 전자문헌을 보다 더 효과적으로 이용할 수 있을 것이라는 전제하에 이용자의 정보수용과정에 동원되는 인지적 기능을 모델화하고, 인지적 과정을 고려한 내비게이션 도구에 적용해야 할 기능을 정보검색 기능, 정보검색 결과의 시각화 기능, 내용구조 분석 기능, 필터링기능, 횡적 브라우징 기능으로 나누어 고찰하였다.
