  • 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.

  • The purpose of this study is to develop a system for predicting students' collaborative problem solving ability based on the ICT factors of PISA 2015 that affect collaborative problem solving ability. The PISA 2015 computer-based collaborative problem-solving capability evaluation included 5,581 students in Korea. As a research method, correlation analysis was used to select meaningful variables. And the collaborative problem solving ability prediction model was created by using the deep learning method. As a result of the model generation, we were able to predict collaborative problem solving ability with about 95% accuracy for the test data set. Based on this model, a collaborative problem solving ability prediction system was designed and implemented. This research is expected to provide a new perspective on applying big data and artificial intelligence in decision making for ICT input and use in education.

  • 여행자들은 여행 중 지도나 네비게이션 (Navigation) 어플리케이션을 종종 사용한다. 하지만 대부분의 지도 지도나 네비게이션 어플리케이션은 비용을 지불하고 네트워크를 사용하여야 하며 실시간으로 많은 지도 이미지를 보여주게 되어 네트워크 비용이 가중된다는 문제점이 있다. 또한, 이를 화면에 표시하기 위해 많은 배터리를 소모하는 문제를 가진다. 이러한 문제를 해결하기 위해서 여행자들의 네트워크 비용 부담을 줄이고, 여행 중 충전이 어려운 스마트폰의 배터리 사용을 최소화 하는 방안을 제안한다. 제안하는 방법은 네트워크가 연결되지 않은 상태에서도 목적지를 안내해주는 안드로이드 기반 응용 프로그램으로, 본 논문에서는 이를 비네트워크 그린 네비게이션(Network-free Green Navi) 라고 명한다. 비네트워크 그린 네비게이션은 최소한의 발광 이미지를 사용하며 오직 GPS 센서만을 사용해 간단하게 목적지를 안내해준다. 이는 여행 중 문제가 되는 요소를 단순하지만 근본적으로 해결하였다는 점에서 큰 의미를 가진다.

  • It is easy to assume that contradictions are logically incorrect or empty sets that have no solvability. This dilemma, which can not be done, is difficult to solve because it has to solve the contradiction hidden in it. Paradoxically, therefore, contradiction resolution has been viewed as an innovative and creative problem-solving. TRIZ, which analyzes the solution of the problem from the perspective of resolving contradictions, has been used for people rather than computers. The Butterfly model, which analyzes the problem from the perspective of solving the contradiction like TRIZ, analyzed the type of contradiction problem using symbolic logic. In order to apply an appropriate concrete solution strategy for a given contradiction problems, we designed the Butterfly algorithm based on decision making tree. We also developed a visualization tool based on Python tkInter to find concrete solution strategies for given contradiction problems. In order to verify the developed tool, the third grade students of middle school learned the Butterfly algorithm, analyzed the contradiction of the wooden support, and won the grand prize at an invention contest in search of a new solution. The Butterfly algorithm developed in this paper systematically reduces the solution space of contradictory problems in the beginning of problem solving and can help solve contradiction problems without trial and errors.

  • 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.

  • 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.

  • The purposes of this study were to examine the general tendency of knowledge and problem solving abilities of children to cope with climate change and to find out whether there is a difference in the ability to cope with climate change based on the gender and age of young children. For this purpose, 129 children aged 5 and 6 who are attended in day care center in Seoul and Gyeonggi area were selected. We used 10 questions to measure climate change response knowledge modified environment conservation knowledge checklist and used five problem solving situations to measure climate change response problem solving ability modified safety problem solving ability test item. The collected data were analyzed using mean, standard deviation, two-way ANOVA, and Pearson's correlation coefficient. As a result, 6-year-old children's knowledge of climate change response and ability to solve climate change problems was higher than that of 5-year-olds. There was no gender difference in knowledge of climate change response and ability to solve climate change. The higher the knowledge level of children's response to climate change, the higher their ability to solve climate change response problems. The results of this study confirmed the association between children's knowledge of climate change response and problem solving ability and showed that a more systematic curriculum for improving knowledge and problem solving ability for preventing climate change needs to be provided to children.

  • In secondary education, learning a computer science subject has the purpose to improve creative problem solving ability of students by learning computational thinking and principles. In particular, learning algorithm has been emphasized for this purpose. There are studies that learning algorithm has the effect of creative problem solving based on the leading studies that learning algorithm has the effect of problem solving. However, relatively the importance of the learning algorithm can weaken, because these studies depend on creative problem solving model or special contents for creativity. So this study proves that learning algorithm has the effect of creative problem solving in the view that common problem solving and creative problem solving have the same process. For this, analogical reasoning was selected among common thinking skills and divide-and-conquer algorithm was selected among abstractive principles for analogical reasoning in sorting algorithm. The frequency which solves the search problem by using the binary search algorithm was higher than the control group learning only sequence of sorting algorithm about the experimental group learning divide-and-conquer algorithm. This result means that learning algorithm including abstractive principle like divide-and-conquer has the effect of creative problem solving by analogical reasoning.

  • 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.
