본 연구는 EPL학습을 문법 교수 학습방법인 연역적 교수 학습방법과 귀납적 교수 학습방법으로 접근했다. 엔트리 사이트에서 초등 5~6학년 학생을 대상으로 제공하는 강의를 연역적 학습과정으로 정했다. 이를 바탕으로 귀납적 학습 과정을 개발하고 각 학습과정을 12차시로 구성했다. 연구를 진행한 후 두 그룹 간 EPL 활용능력평가, 학습 만족도 및 몰입도 검사를 실시했다. 연구결과 두 그룹 간 통계적으로 의미 있는 결과를 얻기는 어려웠다. 하지만 세 가지 검사에서 귀납적 교수 학습방법을 적용한 그룹의 평균값이 모두 높았다. 학습과정을 장기적으로 구성하여 연구를 실행한다면 두 그룹 간 통계적으로 의미 있는 결과를 나태 낼 것으로 생각한다.

이 연구는 과학철학에서 논의되어온 과학의 선언적 지식의 생성 과정을 보다 체계적으로 분석하고 정리하여 하나의 구조화된 과학적 지식의 생성 모형을 제시하고자 하였다. 이를 위해, 이 연구는 선언적 과학 지식의 생성 과정을 과학철학적 관점들을 중심으로 다양한 문헌들을 분석하고, 이러한 분석 결과를 바탕으로 과학적 지식의 생성 모형을 체계적으로 구조화하였다. 이를 통해 고안된 모형은 귀납적 과정, 귀추적 과정, 연역적 과정 등으로 구분되는 지식 생성 과정을 포함한다. 또, 각각의 과정은 다시 여러 단계의 하위 과정으로 구성되어 있음을 보여준다. 이 모형에 의하면, 먼저 귀납적 과정은 관찰과 규칙성 발견 과정으로 구분되며, 다시 관찰은 단순관찰과 조작관찰로 나뉘고, 규칙성발견은 공통점발견, 분류, 위계 발견 등으로 세분된다. 그리고 귀추적 과정은 의문 생성과 가설생성 과정으로 구분되며, 여기에서 가설생성과정은 다시 의문상황 표상, 경험상황 동정, 원인적설명자동정, 가설적설명자 동정 등의 과정으로 나뉘어 진다. 마지막으로 연역적 과정은 방법 기준의 고안 과정은 다시 가설의 검증방법 고안과 가설의 평가기준 고안으로, 가설평가 과정은 결과수집 과정과 가설평가 및 결론 진출 과정으로 세분된다.

For many industrial processes there are good static models used for process design and steady state operation. By using system identification techniques, it is possible to obtain black-box models with reasonable complexity that describe the system well in specific operating conditions [1]. But black-box models using inductive modeling(IM) is not suitable for model based control because they are only valid for specific operating conditions. Thus we need to use deductive modeling(DM) for a wide operating range. Furthermore, deductive modeling is several merits: First, the model is possible to be modularized. Second, we can increase and decrease the model complexity. Finally, we are able to use model for plant design. Power plant must be able to operate well at dramatic load change and consider safety and efficiency. This paper proposes a simplified nonlinear model of an industrial boiler, one of component parts of a power plant, by DM method and applies optimal control to the model.

In order to properly interpret and process or operators in deductive databases including indefinite clauses, we propose to use Lasez′s Strong Model Semantics(LSMS) which is reasonably simple yet powerful enough to support both exclusive and inclusive interpretations. Conventional semantics either fail to support both interpretations or simply too complex. Therefore, in this paper we study advantages and difficulties of representing indefinite information, and as for the solution to difficulties, we show how LSMS can be used to support both inclusive or and exclusive or interpretations. We also investigate and analyze it′s properties and show how it semantically differs from others. We believe that LSMS is the only "reasonably simple" semantics that supports both inclusive and exclusive interpretations.

The main objective of the study is to introduce ideals of Sheffer stroke Hilbert algebras by means of fuzzy points, and investigate some properties. The process of making (fuzzy) ideals and fuzzy deductive systems through the fuzzy points of Sheffer stroke Hilbert algebras is illustrated, and the (fuzzy) ideals and the fuzzy deductive systems are characterized. Certain sets are defined by virtue of a fuzzy set, and the conditions under which these sets can be ideals are revealed. The union and intersection of two fuzzy ideals are analyzed, and the relationships between aforementioned structures of Sheffer stroke Hilbert algebras are built.

This paper defines measurement index items and weight of the index for the purpose of developing a performance measurement index that balancedly measures performance of B2B electronic commerce. The deductive research is used for the development of measurement index items and Analytic Hierarchy Process(AHP) method for the development of weight of the index. This paper has four performance measurement perspectives-finance, partners, business process and human resources, which based the existing researches of balanced performance measurement. This researchers developed eleven second level criteria and twenty-six indexes under four perspectives through the deductive method and expert interviews, weighted on the perspectives, criteria and indexes in accordance with the forms of e-marketplace-vertical and horizontal. As a result, the most important indexes are the maintenance of partners and the efficiency of operation process in the vertical e-marketplace. In the horizontal e-marketplace, the collection of partners, development and prediction processes are more important than other indexes.

While most previous studies have developed educational programs for science gifted children and have analyzed the differences between science gifted children and ordinary children using quantitative research methods, few have investigated the differences among the science gifted, especially in terms of the scientific thinking process. The present study was conducted to explore the thinking characteristics of the elementary science gifted according to the three scientific thinking process types during the scientific problem solving process. The study resulted in the collected of quantitative and qualitative data through tests and an interview with questions and scientific problems which required the use of one of the three scientific thinking processes. Ten elementary science gifted children served as interviewees. Two types as an opistemological basis for solving the problems are revealed on inductive thinking problems. Three types are on abductive thinking, and Three or Four types are on deductive. The results are expected to have an influence on the teaching and the evaluation of the elementary science gifted.

Developing mathematical thinking skills is one of the most important goals of school mathematics. In particular, recent performance based on assessment has focused on the teaching and learning environment in school, emphasizing student's self construction of their learning and its process. Because of this reason, people related to mathematics education including math teachers are taught to recognize the fact that the degree of students'acquisition of mathematical thinking skills and strategies(for example, inductive and deductive thinking, critical thinking, creative thinking) should be estimated formally in math class. However, due to the lack of an evaluation tool for estimating the degree of their thinking skills, efforts at evaluating student's degree of mathematics thinking skills and strategy acquisition failed. Therefore, in this paper, mathematical thinking was studied, and using the results of study as the fundamental basis, mathematical thinking process model was developed according to three types of mathematical thinking - fundamental thinking skill, developing thinking skill, and advanced thinking strategies. Finally, based on the model, evaluation factors related to essential thinking skills such as analogy, deductive thinking, generalization, creative thinking requested in the situation of solving mathematical problems were developed.
