합성전장훈련체계를 통해 지휘관 및 참모 훈련뿐만 아니라 기존의 야외 실기동훈련시 제한 되었던 전투경험을 가능하게 함으로써 전장 적응능력을 향상시킬 수 있으며, 훈련자체가 전투임을 인식하고 전장실상 및 전투양상에 지휘관 및 각개병사의 사고가 지향되도록 할 수 있을것이다. 훈련후에는 추상적이고 주관적인 훈련성과 검증이 아닌 과학적 분석과 정밀한 사후검토 체계에 의한 교훈도출과 특정국면을 재현한 전술토의가 가능하므로 보다 수준 높은 전술적 식견과 전투감각을 향상시킬 수 있을 것으로 기대된다.

Concepts related to the fraction should be taught with formative thinking activities as well as concrete operational activities. Teaching improper fraction should follow the concept of fraction as a relation of two natural numbers. This concept is also important not to be skipped before teaching the fraction such as "4 is a third of 12". Mixed number should be taught as a sum of a natural number and a proper fraction. Fraction as a quotient of a division is a hard concept to be taught since it requires very high abstractive thinking process. Learning the transformation of division into multiplication of fractions should precede that of fraction as a quotient of a division.

수학은 추상적인 학문이다. '추상'은 몇 개 또는 무한히 많은 사물의 공통성이나 본질을 추출하여 파악하는 사고작용이다. 이렇게 추상된 것들을 모아 분류를 하고 그 다음에 이름을 붙이는 것이 바로 개념이 형성되는 과정이고 수학자가 수학을 하는 과정이다. 이 개념들은 여러 가지 모양으로 결합하여 스키마라고 부르는 개념 구조를 형성하게 되는데, 이 스키마는 수학적 사고를 하는데 매우 중요한 역할을 하여 수학을 개념적으로 이해하는데 도움을 주며, 새로운 지식을 얻는데 필요한 필수적인 도구가 된다. 본 논문에서는 연속적인 수열의 합의 공식에 대하여 학생들이 Skemp가 말한 '관계적 이해'를 할 수 있도록 스키마를 이용하여 문제를 해결할 수 있는 모델과 원주의 스키마를 이용한 생활 속의 문제를 제시하여 학생들이 공식을 암기하기보다는 수학의 구조를 파악하고 연계성을 이해함으로서 능동적인 구성활동을 유발하여 수학에 대한 흥미를 느낄 수 있도록 도움을 주고자 한다.

수학은 추상적인 학문이다. '추상'은 몇 개 또는 무한히 많은 사물의 공통성이나 본질을 추출하여 파악하는 사고작용이다. 그리고 이 추상들이 모여 분류(유사성을 기초로 해서 우리의 경험을 함께 묶는 것)가 되고 그 다음에 이름이 붙여진다. 이것이 바로 개념(concept)이 형성되는 과정이고 수학자가 수학을 하는 과정이다. 그리고 이 개념들은 여러 가지 모양으로 결합하여 스키마(Schema)라고 부르는 개념 구조를 형성하게 되는데, 이 스키마(Schema)는 수학적 사고를 하는데 매우 중요한 역할을 한다. 본 논문에서는 기존의 초등학교 교과서의 소수의 관한 내용에서 교차연결고리가 부족한 부분을 보충한 스키마식 수업 모델을 제시하여 수학의 연계성과 위계성을 강조함으로써 학생들로 하여금 수학의 구조를 파악하게 하여 수학에 대한 흥미와 필요성을 알게 하는데 그 목적을 두고 있다.

정보교육과정은 정보과학적 사고(Computational Thinking)의 향상을 목표로 하고 있다. 정보과학적 사고는 실생활의 다양한 문제를 컴퓨팅 파워를 이용하여 처리할 수 있는 형태로 추상화(Abstraction)하는 영역과 문제를 해결하기 위한 단계를 정의하는 자동화(Automation)하는 영역으로 구분할 수 있다. 정보 교육에서 추상화는 문제를 해결하기 위해서 데이터의 속성을 정의하고 구조화하거나 데이터들의 추상적인 관계와 의미를 분석하는 것으로 정보탐구 중심의 정보교육이라 할 수 있고, 자동화는 문제를 해결하는 절차 혹은 단계를 정의하고 이를 컴퓨팅 파워를 이용하여 자동적으로 처리할 수 있도록 하는 것으로 정보처리 중심의 정보교육이라고 할 수 있다. 본 연구는 정보교육의 두 가지 핵심영역에 따라 학습자가 인식하는 정보교육이 어떻게 다른지를 분석하고자 하는 목적으로 학습자의 정보교육에 대한 흥미, 가치, 자신감과 더불어 정보탐구와 정보처리 중심의 정보교육에 대한 인식의 차이를 분석하였다.

Graphic thinking for the idea sketches brings about variations between abstract realm and concrete one, and between conceptual realm and perceptual one. When design information is projected to the thinking process, some images are generated, and transformed. We reviewed the sketching devices for computerization to deal with a lot of design data in the computing environment. The LCD Tablet can be a substitute for the Pen & Paper to get rid of irksome tasks at handling the design data. Using a protocol analysis technique, we examined the influences of different design information, which is consisted of verbal concepts and/or visual images, and abstract information and/or concrete one. The findings show that there are no significant differences of influences between verbal/visual information and abstract concrete information at the conceptual design. These facts support that graphic thinking process is progressed with the perceptual and mental image.

The purpose of this study is to investigate the features of elementary students' intuitive thinking emerged during problem solving activities as it related to thermal phenomena, focusing on when intuitive thinking appears and how it is related to logical thinking. For this, we presented a problem related to thermal phenomena to nine 5th-grade students, and examined how students' thinking emerged in the activities. We conducted clinical interviews to investigate the thinking process of students. The results of this study are as follows. First, students made their own solutions and justified it later during the emergence process of intuitive thinking. It was also found that students connected concrete materials and abstract concepts intuitively. They solved the problem by making predictions even when information is insufficient. Second, it was shown that intuitive thinking can emerge through the intended strategies such as drawing a mental image, thinking from a different perspective, and integrating methods. These results, which are related to the students' intuitive thinking has received little attention and will be the basis for helping students in the context of discovery of their problem solving activities.

In this study, we investigated the thinking processes of 7th grade science-gifted students in designing application experiments and analyzed their performance levels in the categorized processes. The analyses of the results revealed that they considered 'setting a problem situation,' 'deciding a strategy,' 'identifying the assumptions,' 'defining the measurements,' and 'validating the assumptions' in the processes of designing experiments. However, their performance levels of the categorized processes were found to be rather low. It was especially insufficient in setting the situations concretely appropriated to solve the problems and checking their own thinking critically by proper criteria. Therefore, we suggested a potential learning strategy for designing experiments such as replacing difficult and abstract situations to concrete and familiar situations. These results may offer some implications in developing an education program for science-gifted students to foster creativity by emphasizing scientific thinking skills such as experiment design ability.

This paper focuses on the idea development as a creative thinking process for design innovation. The process of thinking has the thinking structures of abduction and transformation. After we had studied the design thought, we found a structure of a thinking system, and created a creative thinking model with this. Using job analysis, we examined the duster of design jobs, which form the design process, and verified the thinking model. The findings suggest that our idea development has the creative process not only of divergent thinking and convergent one, but also of transformation in design. In same time, the design thinking shows their pattern of transition from abstract concept to concrete object. Between the design jobs, idea development shows higher difficulty than other jobs - marketing, product planning and follow-up. Combining the D-T-C (Divergent-Transformation-Convergent) thinking with abstract-concrete thinking, we designed a DFD(data flow diagram) for an early model of computer mediated thinking system (CMTS). This has implications for design support.

This study identifies problems of the administrative legislation (or the delegated legislation) by analyzing articles of laws, orders, and ordinances regarding the sinking of Sewol. According to the result, both of Rescue and Aid at Sea and in the River Act and Marine Transportation Act require to be complemented by additional administration legislations. Therefore bureaucrats enacted defective orders and ordinances, which became an institutional background of the sinking of Sewol. In other words, excessive administrative legislations enabled the Marine Rescue and Savage Association to exert exclusive authorities and caused insufficiencies of supervision over the Association and management for safe navigations. They resulted in corrupt relationships between bureaucrats and businesses and eventually brought citizens' lifes in mortal danger. Consequently, specialty of congressmen should be improved to avoid these excessive administration legislations. At the same time, autonomous control of the administration itself should get enhanced to regulate them. The theoretical implication of this study is that problems of the administrative legislation and necessity of the control by the National Assembly, which have been discussed abstractly and normatively, are clarified empirically, and the practical implication is that the institutional background of the sinking of Sewol is clarified and solutions to improve the institutions are proposed.
