This study aims to suggest an instructional design to improve CT(Computational Thinking) skills in terms of problem solving. CT can be defined as a thought processes for computer-based problem solving. Examining the related CT concepts in the general problem solving process can be helpful for learners to understand CT. For this, this study selects the key elements of CT through literature review, describes how the elements are related to each phrase of the problem solving process, and explores cognitive aspects of the CT elements. In addition, this study describes learning activities and learning assessments of the CT elements according to each phrase of problem solving process and suggests a basic instructional design framework for CT in view of problem solving.

벡터는 수학 문제해결을 위한 중요한 도구로써, 벡터를 이용한 문제해결 과정에서 학생들은 수학적 탐구 활동에 관련된 풍부한 경험을 가질 수 있다. 본 연구에서는 벡터를 이용하여 삼각형의 무게중심에 관한 정리를 증명하기 위한 수학적 탐구 능력이나 아이디어를 학생들이 준비할 수 있도록 정리 증명과 관련된 몇몇 문제들을 체계화하여 제시하였다. 이 문제들을 해결하는 과정에 관련된 탐구 능력을 추출하였으며, 체계화된 문제에 바탕을 둔 무게중심에 관한 정리 증명을 제시하였고, 증명 과정과 관련된 수학적 탐구 능력을 제시하였다.

21세기 지식정보사회에서는 창의력, 문제해결력 등의 고등인지사고능력이 요구된다. 따라서 본 연구에서는 두리틀을 이용한 프로그래밍 수업을 통해 아동의 창의력과 문제해결력을 향상시키고자 한다. 아동의 프로그래밍 활동을 능동적으로 할 수 있는 환경을 조성하여 주되, 교사가 문제해결 과정에 따라 학습진행 과정을 모니터링하여 학생들의 문제해결 능력을 신장시켜주는 안내된 발견식 수업 모형을 적용하였다. 컴퓨터 프로그래밍의 과정에 필요한 인지적 요구사항을 토론이나 소크라테스식 질문을 통하여 반드시 거치도록 안내하였다. 초등학교 5학년 학생을 대상으로 두리틀을 이용하여 안내된 발견식 수업모형을 적용 한 결과 창의성과 문제해결력 측면에서 효과가 있음을 알 수 있었다.

수학 학습은 구체적인 사물의 조작을 통해 추상적인 개념을 습득하는 과정이다. 이 과정에서 여러 가지 학습 도구들이 사용되어지는데, 그 중에서 컴퓨터를 활용한 Logo프로그램을 도입하여, 도형 문제해결과정에서의 부정확한 도형 개념과 정의로 인한 오류를 줄여 정확한 개념과 정의를 형성하는 지도 방안을 마련하고, 실제 수업을 통하여 일반적 수학 도형 수업보다 Logo를 활용한 수학 도형 수업이 도형 문제해결과정에서 학습자가 오류를 줄이는데 효과가 있는지 알아보고자 한다.

The purpose of the study is to analyze the 4th graders' visual representation in mathematics problem solving process and to find out how to teach the visual representation in mathematics problem solving process. on the basis of the results, this study gives several pedagogical implication related to the mathematics problem solving. The following were the conclusions drawn from the results obtained in this study. First, The achievement level of students and using visual representation in the mathematics problem solving are closely connected. High achieving students used visual representation in the mathematics problem solving process more frequently. Second, high achieving students realize the usefulness of visual representation in the mathematics problem solving process and use visual representation to solve mathematical problem. But low achieving students have no conception that visual representation is one of the method to solve mathematical problem. Third, students tend to especially focus on 'setting up an equation' when they solve a mathematical problem. Because they mostly experienced mathematical problems presented by the type of 'word problem-equation-answer'. Fourth even through students tried visual representation to solve a mathematical problem, they could not solve the problem successfully in numerous instances. Because students who face a difficulty in solving a problem try to construct perfect drawing immediately. But generating visual representation 2)to represent mathematical problem cannot be constructed at one swoop.

The higher thinking skills, such as creativity and problem-solving about a given problem, are difficult to assess and diagnose. For an accurate diagnosis of these higher thinking abilities, we need to fully observe learner's problem-solving process or learner's individual reports. However, in an online learning or virtual class environments, evaluation of learner's problem-solving process becomes more difficult to diagnose. The best way to solve this problem is through reporting by tracking learner's actions when he tries to solve a problem. In this study, we developed a module which can evaluate and diagnose student's problem-solving ability by tracking actions in MS-Office suite, which is used by students to solve a given problem. This module performs based on the learner's job history through user tracking. To evaluate the effectiveness of this diagnostic module, we conducted satisfaction survey from students who were preparing the actual MOS exams. As a result, eighty-one (81) of the participants were positive on the effectiveness of the learning system with the use of this module.

This study deals with the process by which 'Social problem-solving R&D model' is established in Korean society through the evolution of the government's R&D program. We will examine the process by which a 'Social problem-solving R&D model', which was not present in companies, science and technology communities, and civil society, is formed through government R&D programs. To this end, we present a conceptual framework to analyze the process of co-evolution of 'Social problem solving R&D model', the organizational community that supports and implements it, and the institutions that supports the new model. In the synthesis, policy measures to enhance 'Social problem-solving R&D model' are dealt with.

프로그래밍 교육은 프로그래밍에 필요한 지식 교육부분과 문제해결능력과 연관된 프로그래밍 전략을 교육하는 부분이 함께 필요하다. 프로그램 작성 기술을 교육하는 과정은 단순한 지식 습득과정이 아니므로 수업과정에서 학습자 스스로 문제해결능력을 배양할 수 있는 유도과정이 필요하다. 이러한 특성의 프로그래밍 수업의 대표적인 수업방식은 실습방식으로, 실제 수업에서 학습자들의 서로 다른 수준을 고려하면서 실습수업을 효과적으로 운영하기에는 수업시간에 대한 제약이 많이 발생한다. 본 연구에서는 프로그래밍 교육에서 사전 프로그래밍 과제를 활용하여 주어진 학점과 시간 안에서 실습 중심의 학습 효과를 높일 수 있는 교수 학습 모델을 제시한다. 이를 통해 프로그래밍 언어 교육 과정에서 발생하는 제한된 실습수업 시간으로 인해 학습자 스스로가 문제해결능력을 배양할 수 있도록 유도하는 수업을 실시하는데 발생하는 어려움을 해결하여, 학습자가 문제해결능력을 향상시키고 좋은 프로그램 작성 기준에 적합한 프로그램 개발 능력을 배양하는 결과를 얻을 수 있었다.

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.

This study has its purpose on improving mathematic education by analyzing the effects of the teaching and learning process which adopted 'FOCUS Problem Solving Steps' on student's mathematical problem solving ability and their mathematical attitude. The result is as follows. First, activities through FOCUS Problem Solving Steps showed positive effect on students' problem solving ability. Second, among mathematical attitudes, mathematical curiosity, reflection and value are proved to have statistically meaningful effect and from the result that analyzed changes of subject students, we could suppose that all 6 elements of mathematical attitude had positive effect. Third, by solving questions through FOCUS steps, students felt satisfaction when they success by themselves. If projects which adopted FOCUS Problem Solving Steps take effect continuously by happiness from the process of reviewing and reflecting their own fallacy and solving that, we might expect meaningful effect on students' problem solving ability. Through this study, FOCUS Problem Solving Steps had positive effect not only on students' mathematical problem solving ability but also on formation of mathematical attitude. As a result, it implies that FOCUS Problem Solving Steps need to be applied to other grades and fields and then studied more.
