The purpose of this study is proposing implications toward liberal arts Informatics education at universities in Korea by analyzing Japan's liberal arts Informatics curriculum standards. For this aim, the changes of the two standards have been compared focusing on a variety of researches related to J07-GE and J17-GE. In order to examine the scope and degree of Informatics knowledge reflecting J17-GE, which is a revised version, the analysis has been conducted through the relationship between curriculum standards regarding CS. As a result of the analysis, it has been identified that principles and knowledge of informatics can nurture competency of university students as universal liberal arts through J07-GE and J17-GE based on Computational thinking viewpoint and Japanese Informatics studies definition. Thus, when it comes to developing curriculum, discussion of not only knowledge system but also number of classes and methods have to be taken into account. This study is meaningful in the sense that it proposed directions for advancing university liberal arts Informatics education and developing liberal arts Informatics curriculum standards.

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.

본 논문에서는 게임프로그래밍을 위한 마이크로디그리 교육과정을 제안하였다. 마이크로디그리는 특정 분야에서 특정 기술이나 지식을 제공하기 위해 설계된 단기과정의 집중 교육프로그램이다. 본 논문에서는 마이크로디그리 교육과정 운영 사례로 나노디그리로 유명한 온라인교육플랫폼 회사인 Udacity와 해외 대학 중 온라인/오프라인 학위과정뿐만 아니라 Certificate 과정을 체계적으로 운영하고 있는 Full Sail University, 국내 대학 중 소프트웨어 관련 마이크로디그리를 운영하는 경희대학교의 교육과정을 분석하였다. 분석결과 Udacity는 데이터분석, 프로그래밍, 인공지능, 클라우드컴퓨팅 등을 중심으로 교육과정이 운영되고 있다. Full Sail 대학의 게임관련 Certificate 교육과정으로는 Game Business & Esports이 운영되고 있고, 게임프로그래밍을 위한 단기교육과정이 없음을 확인하였다. 경희대학 마이크로디그리 교육과정 중 게임과련 교육과정은 "게임공학마이크로디그리" 교육과정 있다. 이 교육과정은 게임프로그래밍과 관련한 마이크로디그리 교육과정이지만 수강생들의 수준을 고려하지 않은 측면이 있어 비전공자나 초보자가 이수하기에는 한계가 있다고 판단된다. 본 논문에서는 이러한 사례 분석을 통해 게임프로그래밍을 위한 마이크로디그리 교육과정을 설계 제안하였다.

For preservice teachers' instrumental-to-relational pedagogical content knowledge transformations, this research designed several didactical tasks based on Kinach's cognitive strategies. The researcher identified preservice teachers' understanding about what is a definition and how to teach it. By challenging their fixed ideas about definitions, the researcher could motivate them to embrace the new teaching approach which guides reinvention of definitions. The PCK development was not the simple process of filling their tabular rasa PCK with theories of mathematics education, but the dialectical process of identifying, challenging, changing and extending preservice teachers' existent PCK. This research will contribute to explore new directions of mathematics teachers' PCK development and the method of teacher education.

Although the need for overall amendment of curriculums recognized, tentative plan for amendment is being established without improving the sense of satisfaction of the users of curriculums from the nation-wide dimension and without review on philosophical and educational psychological viewpoints on curriculum with focus on curriculums that reflects the national and social demands until the tentative plans for amendment of computer subject is made at the time of amendment. Therefore, new/old curriculums has been compared and analyzed from philosophical and psychological viewpoint of curriculums in order to definitively establish status and identity of curriculum, and to cope with changes in educational system. It can be seen from the outcome of such comparative analysis that goals of the philosophical viewpoint of amended curriculum had been defined as discipline-centered curriculum while that for the knowledge-based viewpoint on constructivism and cognitivism.

The purpose of this study is to explore the cognitive achievement characteristics by group of achievement levels in the PISA 2018 science domain compared to the results of the PISA 2015, and to compare and analyze the 'epistemic' knowledge in the revised curriculum 2009 and in the revised curriculum 2007. The average correctness rates in PISA 2015 and PISA 2018 were analyzed by sub category of the evaluation frame in the PISA scientific domain. In the competencies domain, especially, the average correct answer rates of 'evaluating and designing scientific inquiry' were the lowest in medium and lower groups, but the rates rose in all achievement groups compared to PISA 2015, which is encouraging. Although the answer rates were low for both 'living system' knowledge and 'epistemic' knowledge in the knowledge domain, the average answer rates of the upper and middle groups increased in 'epistemic' knowledge compared to PISA 2015. The changes in the curriculum experienced by students participating in PISA were analyzed in relation to the 'evaluating and designing scientific inquiry' competency and 'epistemic' knowledge, which increased in average correct answer rates. In terms of understanding science, the "What is science?" unit that explicitly presents epistemic knowledge, and nature of model in inquiry activities, were explicitly presented in the revised curriculum 2009. In terms of understanding the process of justifying scientific knowledge, the number of inquiry activities increased, scientific explanations based on experimental results strengthened, and the "Science and Human Civilization" unit was introduced to help students to understand STS while simultaneously conducting arguments. These findings confirm the educational performance of groups by achievement level in the PISA 2018 scientific domain and suggest that the direction of education relates to epistemic knowledge in Korea's Science curriculum.

In order to investigate the composition and characteristics of instructional objectives in a teaching-learning material for gifted elementary students in science, 217 instructional objectives across 13 themes in 4 areas of 'energy','materials', 'life' and 'earth' were analyzed by Bloom's revised taxonomy of educational objectives. Four types of factual, conceptual, procedural and meta-cognitive knowledge in knowledge dimension were all comprised in the objectives. Conceptual knowledge was primary constituent of the objectives and the proportion of factual knowledge was the least. On the other hand, all 6 categories of 'remember', 'understand', 'apply', 'analyze', 'evaluate' and 'create' in cognitive process dimension were also comprised in the objectives. The category of 'understand' was primary constituent and that of 'remember' was the least one. While conceptual knowledge in knowledge dimension was primary constituent of the objectives in 'energy', 'materials' and 'earth' areas, procedural knowledge was the most objectives in 'life' area. The least type of knowledge was factual knowledge in all 4 areas. In cognitive process dimension, the category of 'understand' was primary constituent and that of 'remember' was the least one in all 4 areas. In conclusion, it was showed that the instructional objectives in the teaching-learning material reflected the characteristics of educational objectives for gifted students in science.

The purpose of this study is to establish the standard curriculum for informatics by reflecting the changing information technology and social needs and based on the competencies that school at each level must have. To accomplish the purpose, the informatics curriculums of 8 countries were analyzed, and the learning elements of the curriculum were extracted with the body of knowledge of the higher-level informatics standard curriculum being the frame. To establish the standard curriculum, 51 experts reviewed it and their opinions were collected 10 times. As a result of this study, the competencies that need to be fostered through the informatics curriculum were defined, and the competency-centered curriculum, including the learning elements required to acquire the competencies, and the competencies that can be manifested through the learning element, was proposed. The implication is that the informatics standard curriculum, proposed in this study, laid down the foundation for establishing the informatics curriculum scheduled to be revised in 2022.
