The purpose of this study was to compare and analyze the science process skills and teaching methods between the 6th and the 7th elementary school science textbooks. For this study, science textbooks and teacher's guidebooks from the 3rd to the 6th grade were analyzed. In this research the science process skills are divided by basic process skills(BPS) and integrated process skills(IPS). The BPS is composed of observing, classifying, measuring, predicting and inferring skill, which are 5 subcategories. The IPS is composed of problem cognition, formulating hypothesis, controlling variables, transforming data, interpreting data, drawing result, and generalization, which are 7 subcategories. The results found in the analysis of science process skills in the 6th and 7th science textbooks are as follows: 1. The percentage of the BPS was increased, but the IPS was decreased in the 7th than the 6th. 2. The percentage of the IPS was higher than the BPS in the 6th science textbooks, but the BPS was higher than IPS in lower grade and the IPS was higher than the BPS in higher grade in the 7th textbooks. 3. Observing and problem cognition skill were most dominant in the 6th and 7th science textbooks. 4. The percentages of observing(24.8%), classifying(5.4%), measuring(5.6%), inferring(6.0%) in the BPS and interpreting data(4.4%) in the IPS were increased, but predicting(3.8%), formulating hypothesis(0.5%), controlling variables( 1.8%), transforming data( 1.2%), drawing result(0.8%) and generalization(0.9%) skills were decreased in the 7th. And teaching methods suggested in the curriculum are as follows: the percentages of learning by observation(19.2%) and role play(0.1 %) were decreased, but learning by experiment(6.2%), learning by discussion(2.0%), learning by investigation(4.6%) and creative learning(6,4%) were increased in the 7th than the 6th. In conclusion, it was found that the basic process skills were emphasized in the 7th science textbooks than the 6th and the science process skills in the science textbooks of the 7th curriculum were distributed by the grade level of the elementary children.

As 'Science Inquiry Experiment' is newly introduced in the high school curriculum, where inquiry and experiment oriented education is insufficient, this study aims to analyze teacher's practice of 'Science Inquiry Experiment' in depth and identify contradictions during its process in the perspective of Cultural Historical Activity Theory. The research participant is teacher SHIN who is exclusively responsible for Science Inquiry Experiment. Starting with reflection on the practice of Science Inquiry Experiment class conducted in the first semester, interviews with participants, participatory observation and local materials were used during the 2nd semester's Science Inquiry Experiment class. A descriptive analysis of the teacher SHIN's practice of Science Inquiry Experiment was carried out and the contradictions in the activity system of the teacher SHIN were identified. The result reveals that in the overall practice of teaching Integrated Science and Science Inquiry Experiment, there were contradictions between teacher SHIN's recognition about cooperation(subject) and shared responsibility with other teachers(division of labor), and between teacher SHIN's recognition about the subjects(subject) and contrasting contents in teacher training courses(community). In the practice of teaching Science Inquiry Experiment, there were specific contradictions between teacher SHIN's recognition about the subject(subject) and time of job assignment(rule), between experimental activities(object) and experimental tools(tool), and between purpose of the subject(object) and directions about assessment(rule). These contradictions directly or indirectly influence the practice of teaching Science Inquiry Experiment. There needs to be support for constructing an activity system capable of supporting and promoting teachers' practice of Science Inquiry Experiment, and we made several suggestions to resolve the problems.

학교 현장에서의 컴퓨터 교육은 여전히 시범실습위주로 이루어지고 있으며. 초등학교 컴퓨터 교육에서 많은 비중을 차지하는 소프트웨어 교육은 더욱 그러하다. 소프트웨어는 끊임없이 개발되거나 업그레이드 되고 있어 가르쳐야 할 내용이 많아져 새로운 학습방법이 필요하다. 즉 문제사태에서 필요한 기능을 찾아 스스로 문제를 해결하고 다른 응용소프트웨어에 전이 및 파지할 수 있는 능력을 길러주는 학습방법이 필요하다. 그 방법 중의 하나가 구성주의 학습 원리에 부합한 문제중심학습이며 학습의 효과를 높이기 위해서 온라인과 오프라인학습의 장점을 혼합한 B-러닝 방법이 필요하다. 따라서 본 연구는 응용소프트웨어의 적응력을 향상시키기 위해 한글 워드프로세서 학습내용을 학습자의 수준에 맞게 문제중심으로 재구성하고 온라인 학습을 위해 학급커뮤니티를 설계 및 구현하였다. 그리고 문제중심의 B-러닝에 적합한 학습모형을 설계하여 제시하였다. 문제중심의 B-러닝은 구성주의 학습 원리에 적합한 실생활의 문제를 학습내용으로 하고 면대면 교실수업의 장점과 온라인 학습의 장점을 혼합하여 자기주도적으로 탐구학습을 하는 것이므로 응용소프트웨어의 적응력은 향상될 것으로 기대한다.

In the process of establishing the principle of genetics, Mendel discovered problems based on various observations. Mendel's scientific thinking ability can be effective if this ability is embedded in gifted science education programs. The study aims to develop a science gifted education program utilizing Mendel's scientific thinking ability shown in the principles of genetics and examine students' changes in scientific thinking ability before and after the program implementation. For the program development, first, the characteristics of Mendel's scientific thinking ability in the process of establishing the principle of genetics were investigated and extracted the major elements of inquiry. Second, the science gifted education programs was developed by applying the inquiry elements from the Mendel's Law. The program was implemented with 19 students of $7^{th}$, $8^{th}$ graders who attend the science gifted education center affiliated with university during July 2011. The Mendel's scientific thinking ability was classified into induction, deduction, and integration. The elements of inquiry extracted from the Mendel's scientific thinking include making observation, puzzling observation, proposing causal questions, generating hypothesis, drawing inference, designing experiment, gathering and analyzing data, drawing conclusions, and making generalization. With applying these elements, the program was developed with four phases: $1^{st}$ - problem finding; $2^{nd}$ - hypothesis generating; $3^{rs}$ - hypothesis testing and $4^{th}$ - problem solving. After implementation, students' changes in scientific thinking ability were measured. The findings from the study are as follows: First, students' abilities of problem finding is significantly (p<.05) increased. Second, students' abilities of hypothesis generating is significantly (pp<.05) increased.

The purpose of this study is to analyze cases on teaching solutions exploration of Wythoff's game through using the analogy for the gifted elementary students, to suggest useful teaching methods. Students recognized structural similarity among problems on the basis of relevance of conditions of problems. The discovery of structural similarity improves the ability to solve problems. Although 2 groups-NIM game with surface similarity is not helpful in solving Wythoff's game, Queen's move game with structural similarity makes it easier for students to solve Wythoff's game. Useful teaching methods to find solutions of Wythoff's game through using the analogy are as follow. Encoding process helps students make sense of the game. It is significant to help students realize how many stones are remained and how the location of Queen can be expressed by the ordered pair. Inferring process helps students find a solution of 2 groups-NIM game and Queen's move game. It is necessary to find a winning strategy through reversely solving method. Mapping process helps students discover surface similarity and structural similarity through identifying commonalities between the two games. It is crucial to recognize the relationship among the two games based on the teaching in the Encoding process. Application process encourages students to find a solution of Wythoff's game. It is more important to find a solution by using the structural similarity of the Queen's move game rather than reversely solving method.

오늘날은 과학문명의 발달로 인하여 기존지식의 수명이 점차 짧아져 가고있는 것이 특징이다. 지식의 증가는 단순히 지식의 양을 증가시키는 역할뿐 아니라 많은 기존지식을 불충분하고 쓸모 없는 것으로 바꿔버리게 한다. 그러므로 학교에서는 학생들에게 어떤 특정지식의 축척보다는 그 학문에 내재해 있는 기본적인 지식의 구조를 학습하게 하여 여러 가지 개념을 관련시키는 논리적 방법을 학습하게 하고 합리적인 탐구방법을 구사할 수 있도록 하여 변화하는 미지의 세계에 대처해 나갈 수 있도록 하는 것이 중요하다. 본 연구는 간호학의 기본 지식구조를 확인하는데 그 목적이 있다. 본 연구를 하게 된 동기는 간호업무의 근거로 활용도리 지식체계는 교육과정의 조직원리로 작용될 유형이나 구조를 지니고 있으며 이런 유형이나 구조를 중심으로 간호교육과정을 구성하는 것이 간호교육에 필수적이라는 문제에서 비롯되었다. 연구방법은 1982년 9월부터 1983년 5월에 걸쳐 간호학 문헌을 체계적으로 분석하여 간호학의 개념적 지식구조와 구문적 지식구조를 확인하였다. 그 결과 얻어진 결론은 다음과 같다. 1. 간호학의 개념적 구조： 모든 학문에는 탐구의 대상인 특수현상을 설명하고 서술하는데 활용되는 일련의 실질적, 개념적 구조를 가지고 있다. 그러나 그 학문의 중요한 부분 또는 중심을 포함하고 있는 개념들이 그 분야 또는 학문의 개략이라고 할 수 있는데 연구결과 간호학에서 가장 높은 순위의 대표적 특질을 지닌 개념은 인간, 건강, 환자/대상자, 간호, 행동으로 분석되었다. 2. 간호학의 구문적 지식구조 : 지식구조의 두 번째 요소인 학문의 구문(syntax)은 간호학에서의 특징적인 탐구방법과 관련되나 개념적 구조와 마찬가지로 탐구방법은 학문에 따라 다르며 그 분야의 주요양상을 나타낸다. 연구결과 간호학에서의 특징적인 탐구방법은 공동적으로 간호과정(nursing process)임이 나타났으며 그 요인으로는 사정, 진단, 계획, 수행, 평가의 다섯 단계로 분석되었다.
