초${\cdot}$중등학교 수학교육에 있어서 문제해결에 대한 관심은 전세계적으로 점점 높아지고 있다. 우리 나라 에서는 문제해결 교육을 제 4차 교육과정 개정부터 시작하여 제 7차 교육과정에서도 아주 중요시 하고있다. 이렇게 교육과정의 변화에도 불구하고 수학 교육헌장에서 교사들의 문제해결에 대하여 갖는 인식도나 실천적 의지는 매우 부족하다. 이런 관점에서 첫째는 문제해결력에 관한 제 7차교육과정의 교과서를 분석함으로써 문제해결 지도에 사용되고 있는 문제의 유형을 분석하였다. 둘째는 교사들의 설문지를 통하여 수학 교육에서 문제해결을 위한 교사의 신념을 조사하여 교육 현장에서 문제해결력의 문제점을 분석하여 앞으로의 개선책을 알아본다.

수학 학습의 목표를 수학적 사고력의 신장이라는 측면에서 보았을 때 이를 위하여 문제에 대한 다양한 해법을 찾는 활동은 중요하다. 문제에 대한 다양한 접근은 문제해결의 전략을 학습시키고 사고의 유연성을 길러줄 수 있는 방법이 된다. 문제에 대한 다양한 해법을 찾는 과정에서 이미 알고 있는 지식이 어떻게 응용되는지를 알게 된다. 특히 기하 문제에 대한 다양한 접근은 문제해결의 전략을 학습시킬 수 있는 좋은 예가 된다. 본고에서는 문제해결을 통한 수학적 일반성을 발견하기 위한 방법으로서 문제에 대한 다양한 해법을 연역과 귀납에 의하여 일반화하는 과정을 탐색하고자 한다. 특히 수학 문제에 대한 다양한 해법을 찾는 것은 문제해결 전략으로서 뿐만 아니라 창의적 사고의 신장 측면에서 시사점을 던져준다.

Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

문제해결을 위해서는 제일 중요한 것이 사항의 심각성을 빨리 인식해야 한다는 것과 시간 관리를 철저히 해야 한다는 것이다. 심각성을 인식하는 순간부터 2000년 이전까지의 어떤 방법으로 해결할것인가, 어떤 툴을 이용해서 해결할거라는 생각을 버리고 우리 조직이 이런 문제를 해결하기 위해서 문제를 해결하기 위한 과정에 대한 계획을 세우고, 과정을 진행하면서도 피드백을 통해서 철저하게 관리를 해야 한다는 것이다.

There exist many differences between new Informatics curriculum and the current Computer curriculum. Since the new curriculum introduces new section of "Problem-solving methods and procedures" which are not included in current computer curriculum, it is required to define and specify objectives and content units of "problem solving methods" and "programming" topics for the new section. In this paper, we define and specify the objectives and detailed contents by surveying various computer curriculums used in many other countries. Then, the specified objectives and content units are validated by a group of computer education experts. The final results of specified objectives show that areas of "comprehension", "application" and "synthesis" take relatively high percentage over the other areas. In the content specification, we set the content structure by describing how to solve a given real-world problem with a non-computerized way, followed by representing or transforming it with a corresponding computerized model.

In this paper we solve various triangle construction problems given by three points(a midpoint of side and other two points). We investigate relation between these construction problems, draw out a base problem, and make hierarchy of solved construction problems. In detail we describe analysis for searching solving method, and construction procedure of required triangle.

Problem solving has been consistently emphasized in national mathematics curricula, whereas the foci of such an emphasis have been changed. Given this background, this study traced down major changes in emphasizing problem solving from the first national mathematics curriculum to the most recent 2015 curriculum. In particular, both the 2009 and the 2015 revised curricula were analyzed in detail to figure out the latest emphasis and trends. This paper then investigated whether a series of mathematics textbooks were aligned to the emphases of recent curricula. It finally discussed some issues that we need to reconsider with regards to problems, problem solving strategies, and the process of problem solving. As such, this study is expected to provide textbook developers with detailed implications on how to employ problem solving in new series of textbooks.

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.

Collective intelligence has been focused because it plays an important role for creating knowledge. In order to solve a problem with collective intelligence, collaborative works sharing information are required. In this study, we have investigated what informations are shared while 4 science gifted students are asked for scientific explanation to the problem which is cognitive conflict. They have shared presupposition and problem in stage of problem finding, aims and means of problem solving in stage of setting up hypotheses, and constraints for evaluation and results of evaluation in stage of hypotheses evaluation. Our research tells that group can create knowledge through sharing information and make a change of their concepts. Our foundation of these spontaneous conceptual change gives an implication for gifted education.

전자출판, 하이퍼미디어, 정보관리기술을 주요 기술요소로 한 디지털도서관이 출현하게 되어 정보의 접근과 전달의 문제는 해결하였으나, 동시에 해결해야 할 새로운 문제가 발생하였다. 그것은 디지털도서관의 대상데이터인 정보의 생산과 배포, 이용의 과정에서 발생하는 저작권의 문제인 것이다. 디지털도서관의 저작권문제는 비디지털자료를 디지털화하는 정보의 생산의 과정에서 발생하는 문제와, 디지털 데이터를 이용하는 과정에서 발생하는 문제로 나눌 수 있다. 본 연구에서는 LC의 전자저작권관리시스템을 위해 수행되고 있는 CORDS(Copyright Office Electronic Registration, Recordation ＆ Deposit System) 프로젝트를 토대로 후자의 문제를 해결하기 위한 전자저작권관리의 개념과 구성요소에 대해 논하고자 한다.
