This study investigated the definition and characteristics of computer science problem to be solved through computational thinking. It also explored types and cases of both computer science problems and teaching learning methods to solve computer science problems. Before studying computer science problems, I examined the definition, type, and the importance of problem solving in other subjects. Based on this research, We found that informatics can solve ill-structured problems through computational thinking and the power of computing. This includes counting, decision, retrieval, and optimization problems. Teachers can improve their students' skills in computational thinking, particularly as related to abstraction, automation, and generalization, by choosing the appropriate teaching and learning method or based on the characteristics of the problem.

Developing middle and high students' information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether 'problem-solving methods and procedures' parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection" and "problem-solving strategy proposal". Also a few textbooks haven't satisfied in important indexes and activities. So, we suggest that more 'problem-solving process reflection' and 'problem-solving strategy proposal' parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.

본 논문에서는 디지털 교과서를 활용한 자기주도 문제해결학습 모형을 제안한다. 이 모형은 디지털 교과서를 활용한 수업에 대한 선행 연구 분석을 통해 디지털 교과서를 이용했을 때의 장점을 극대화하는 방향으로 설계되었다. 디지털 교과서를 활용했을 때 학습의 주도권이 교사에서 학생으로 넘어올 수 있도록 학생들이 디지털 교과서를 통해 제공되는 자료를 ICT 도구를 활용해 스스로 분석 정리하고 이러한 일련의 활동을 통해 학생들이 공부하는 방법을 자연스럽게 깨우치도록 하는 데 이 모형의 궁극적인 목적이 있다. 위와 같은 디지털 교과서를 활용한 자기주도 문제해결학습 모형을 학교 수업에 적용했을 때 기대되는 효과로는 문제해결력 향상, 학습에 대한 능동성 강화, 학습동기 증진, 수준별 학습 가능 등이 있다.

An important element to consider in information subjects is problem solving skills. It is problem solving skills that emphasize "practical usage of learning" in which knowledge of information subjects is integrated along with the cross curricular characteristics of the information subjects. What is usually considered paramount in a subject is knowledge, so the question is, should problem solving be considered more important in information subjects? This study discusses the foundation of subjects based on knowledge in information science, and the specifics of the 2014 amendment to the U.K. curriculum. And based on the core subjects of the U.K. curriculum, this study also offers educational implications as to how knowledge and problem solving skills should be discussed.

Previous researches on the improvement of logical thinking in Informatics subject have used general logical thinking test and only limited improvement of logical thinking by programming learning result. In this study, the operational definition of the logical thinking in problem-solving process on Informatics education is different from the general logical thinking and the logical thinking of the other subjects. Firstly, we suggested the operational definition of components of logical thinking using the open questionnaire by expert and research team discussion. Also, we suggested the relationship between the operational definition and contents of the 'problem-solving methods and procedure' section in secondary Informatics subject. Finally, this study developed the evaluation contents based on the operational definition of components of logical thinking. The components of logical thinking which was required in problem-solving process on Informatics subject were ordering reasoning, propositional logic, controlling variables, combinatorial logic, proportional reasoning. We suggested the relationship between operational definition and problem-solving process and assessment of logical thinking in problem-solving process on Informatics subject. This paper will give meaningful insight to supply the guideline of the teaching strategy and evaluation methods for improving the logical thinking in Informatics education.

The dissemination of smart appliances, along with the development of the latest information and communication technology has an effect on society. Their application can be seen in the smart learning environment, by use of digital textbooks with smart devices in the classroom. Hence in this study, the 4L-ACC activity using digital textbooks was applied in the third grade social studies class to improve critical thinking and problem solving skills of elementary school students. This study compared and analyzed the impact in critical thinking and problem-solving skills using digital textbooks versus standard social studies classes. As a result, in social studies classes that used the 4L-ACC activity compared to common social studies classes, elementary student's problem understanding, critical thinking, problem resolution, reflective thinking, and all lower areas of critical thinking and problem-solving were improved. In conclusion, using digital textbooks enhance student's ability to think critically and problem solve. This should provide learners a more comprehensive learning experience and therefore be integrated into more education environment.

The purpose of this study is to verify learning components to be taught in each grade of middle schools, to propose hierarchical structures on algorithm content, and to resolve overlapping across related subjects. In order to verify learning components, four criteria were proposed. To evaluate practical application, they were implemented into The Proposal of Curriculum Revision on Computer Education in Middle School on MPE website. It was found that there was content overlapping between 'problem solving methods and procedures' in the middle school Informatics Curriculum and 'regulation and problem solving' in the Elementary Mathematics Curriculum. So it is needed to find a way to differentiate the contents of 'problem solving methods and procedures' from the other related subjects.

This study aims to investigate the effects of problem-solving competency of students when they study with digital textbook contents and digital inking in collaborative learning. The experimental group solved the math problems using basic digital textbook contents and digital inking while the control group solved the math problems using basic digital textbook contents alone. The result of analysis and comparison is as follows, the experimental group with basic digital textbook contents and digital inking showed more improved problem-solving competency than that of the control group with basic digital textbook contents alone, the experimental group showed recorded a higher satisfactory level than that of the control group.

2015 개정 교육과정의 적용에 따라 학교 현장에 새로운 요구와 문제 상황이 예상되며, 이에 따라 정보 컴퓨터 교사양성과정도 적절하게 변화될 필요가 있다. 본 연구에서는 예비 정보교사들이 교육현장의 요구와 문제 상황에 대해 직접 고민하고 해결방법을 구안해보도록 하는 방법으로 캡스톤 디자인을 적용하였다. 이를 위해 현재 운영 중인 캡스톤 디자인 강의의 동향을 살펴보고 교과교육영역의 과목과 다루어야 할 정보교사의 자격기준을 살펴보았으며, 이를 바탕으로 캡스톤 디자인 정보교과 교재연구 강의를 설계하였다. 후속 연구로 설계한 강의를 예비 정보교사들에게 적용하고, 이에 대한 효과성을 검토할 것이다.
