This study was aimed at identifying the factors of creative ability influencing problem-solving skills for University students majoring in nursing science. A descriptive study was conducted with a sample of 248 students enrolled in a 4-year undergraduate academic program for nursing in one University located in an urban area of Korea. This study used: (a) 25 items of Process Behavior Survey, and (b) 35 items of the Integrative Creativity Scale. The data were collected from Nov. 8th toward Nov. 26th, 2010; the research was conducted through voluntary participation after an explanation about the research. The data were also analyzed with SPSS 18.0 program, using Pearson correlation and stepwise multiple regression methods. Mean score of the level of problem-solving process was 3.62(${\pm}.448$). Problem-solving process was significantly related to creative ability(p<.01). Problem-solving process was significantly influenced by flexibility and elaboration in account for 42.4%. These results imply that in order to foster problem-solving ability, nursing professors need to develop nursing students' creative ability and its factors.

There is a lack of empirical research on the level of students' state anxiety according to their perceived task difficulty when confronting science questions. This study seeks to investigate whether perceived task difficulty moderates the process of arousing students' state anxiety in science learning. In pursuit of this objective, we engaged 410 fifth- and sixth-grade elementary school students (186 fifth graders; 194 females) in solving two science questions. We then verified the moderating effect of perceived task difficulty on the relationship between science anxiety and state anxiety arousal when confronting science questions using the PROCESS Macro Model 1. Results confirmed that science anxiety and perceived task difficulty significantly and positively predicted state anxiety. Notably, perceived task difficulty had a significant moderating effect on the process of arousing state anxiety, where lower perceived task difficulty led to a greater increase in state anxiety after confronting the science questions. We discuss the implications of the findings for science education and propose potential directions for future research.

The primary purpose of this study is to survey multiplicative thinking levels and its characteristics of third graders in elementary school and to analyze how to use it when they solve the proportional problems. As results, the transition thinking ranked the highest among the four kinds of thinking levels when the $3^{rd}$ graders solved the multiplication problems. It means that the largest numbers of students still can not distinguish the additive and multiplicative situations completely and remain in the transition thinking, which thinks both additively and multiplicatively. In addition, the performance of solving proportional problems was distinguished from the levels of thinking. Through this study, we can give some implications of the importance of multiplicative thinking and instructional methods related to multiplication.

This study examines the effects of learner's metacognition and scaffolding types on problem solving processes by examined 49 undergraduates to identify effective scaffolding type in Web-based PBL. This study classifies problem solving processes as defining the problem, developing solutions, making selections and justifications for the Proposed solution(s), and monitoring the solution. Moreover, it classifies scaffolding types as subject-related scaffolding and process-related scaffolding. As a result, the upper metacognition group showed higher performance only in monitoring solutions than the lower metacognioon group. This study also showed that offered scaffolding effects are not statistically significant. However, the lower metacognition group showed higher performance when subject-related scaffolding was offered and the upper metacognition group showed higher performance when process-related scaffolding was offered in making selections and justifications for the proposed solution(s) and monitoring solution. This study, based on the result of research, can partially verify the effects of learner's metacognition on problem solving processes and interaction effects between scaffolding and metacogniton in Web-based PBL.

In this study we investigated the effects of using GSP in solving geometric problems. Especially we focused the effects of GSP in leveled students' connection of geometry and algebra. High leveled students prefer to use algebraic formula to solve geometric problems. But when they did not know the geometric meaning of their algebraic formula, they could recognize the meaning after using GSP. Middle and low leveled students usually used GSP to obtain hints to solve the problems. For the low leveled students GSP was usually used to understand the meaning of the problem, but it did not make them solve the problem.

소비자의 의사결정에 관한 대부분의 연구는 상표수준(brand level) 선택에 그 초점을 맞추고 있으나, 소비자는 제품수준의 의사결정상황에 자주 직면하게 된다. 따라서 본 연구는 제품수준(product level)에서의 의사결정문제에 접하게 될 때 소비목적을 달성하기 위하여 제품 수준에서는 환기군에서 유도된 고려군을 어떻게 형성하는지를 전형성의 개념을 이용하여 살펴보았다. 그리고 이를 통해 선택된 특정제품에 대한 상표대안들에 대하여 환기군에서 유도된 고려군이 형성되는 전반적인 과정을 제품수준과 연결하여, 제품수준과 상표수준에서의 고려군 형성과 대안평가의 차이를 비교하였다. 연구결과 제품수준의 경우에서는 대안평가기준이 상표수준보다 추상적인 속성을 이용하고 있는 것으로 나타났고, 상표수준의 경우에는 제품수준보다 구체적인 속성을 이용하는 것으로 나타났다. 또한 제품수준과 상표수준에 있어 전형성 평가기준의 영향력이 다른 것으로 나타났는데, 이상적 속성과 속성구조가 고려군을 형성하기 위한 대안의 전형성 평가에 많은 영향을 미쳤으며, 상표수준의 경우에는 공통속성이나 접촉빈도가 더 많은 영향을 미치는 것으로 나타났다.

The purpose of this study was to analyze children's proportional reasoning process on an ill-structured "architectural drawing" problem solving and to investigate their level and characteristics of proportional reasoning. As results, they showed various perspective and several level of proportional reasoning such as illogical, additive, multiplicative, and functional approach. Furthermore, they showed their expanded proportional reasoning from the early stage of perception of various types of quantities and their proportional relation in the problem to application stage of their expanded and generalized relation. Students should be encouraged to develop proportional reasoning by experiencing various quantity in ration and proportion situations.

오늘날의 교육은 단순히 지식을 많이 습득하는 것보다 문제를 인식하고 지식 및 정보를 통합하여 창의적으로 문제를 해결할 수 있는 역량 중심의 교육을 강화하고 있다. 이러한 역량을 배양하고 함양하기 위해 학생들의 발달 수준을 알아보고 분석하기 위해 국제 수준의 학업 성취도 평가 연구가 국제기구를 중심으로 활발히 이루어지고 있다. 학습자들의 역량을 효과적으로 평가하기 위해 최근에 컴퓨터 기반 평가가 도입되고 있다. 본 연구에서는 국제 수준의 학업 성취도 평가에서 컴퓨터 기반 평가가 이루어지는 현황을 파악하고 PISA와 ICILS의 공개 문항의 특징을 비교하여 시사점을 제시하였다.

최근의 새로운 교수 학습 형태인 웹기반 교육에서의 가장 중요한 요소는 시.공간적으로 떨어져 있는 학습자의 학습 상황을 파악하고 분석하여, 학습자에게 적절한 학습내용과 과정을 제시하는 하는 것이 무엇보다도 중요하다. 본 연구에서는 웹기반 교수 시스템에서 학습자의 수준에 맞는 적합한 학습 내용과 평가 문제를 제공하고, 그 평가 결과를 분석하여 반복학습 및 심화학습을 효과적으로 제공하고, 차기 학습을 할 경우에 이에 기초하여 적절한 학습이 이루어질 수 있도록 한다. 이를 위해 코스웨어를 설계시 학습목표의 중요도, 학습내용의 난이도, 학습목표와 학습내용과의 관련성과 각 항목의 가중치를 고려한 퍼지 함수에 의해 퍼지 소속성을 가진 퍼지 언어 변수로 각 프레임에 대한 수준을 표현한다. 또한, 학습의 평가도 문제의 난이도, 관련학습 자료의 난이도, 관련 학습목표의 중요도, 각각의 관련성을 고려하여 퍼지 함수에 의해 언어 변수로 평가된다. 이와 같이 퍼지 함수를 이용함으로써 학습자의 수준을 분석하고, 이에 적절한 학습 및 평가 내용을 제공하는데 여러가지 다양하고 불확실한 요소들을 고려하여 처리함으로써 보다 융통성 있고 효과적인 교수 학습 방법이 될 수 있다.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA(Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In particular, the integration of business processes and interfaces are important. Therefore, intuitive and easy to implement business process modeling is required. In this paper analyzes business process between enterprises, modeling the service-oriented business process with BPEL to realization level. Also, In this paper suggests that UML is used from high-level business problems to the process of low-level problem for Visual and effectively.
