As the importance of software education is emphasized, various educations for improve the computational thinking of elementary school students are being provided. However, there are many limitations that apply to the school at preceding studies. because they were invented for specific environment or students. Therefore, in this study, software education was conducted by constructing teaching-learning activities in consideration of the characteristics of students such as teaching aids and level of computational thinking ability, which can influence students based on the contents of textbooks. Through the comparison about computational thinking improvements, this study tried to suggest the direction of effective software education method. As a result, there are differences in computational thinking improvements according to the student's level and used teaching aids. Specifically, visual programming and unplugged type teaching-learning activities were more effective in teaching aids, and according to the level of students, students with low level of computing thinking in pre-inspection showed relatively high improvement. This tendency suggests that it is necessary to consider various learning factors in designing teaching-learning activities in elementary software education.

With the development of the realm of software and its getting the limelight, technical-specialized high schools are trying hard to improve their students' ability in terms of the realm of software in the latest. This study compared and analyzed targeting for students who are learning Java program how much the type of personality of learners influences on the improvement of the resilience. As a result, the learners having introverted personality didn't have a meaningful result on the improvement of the resilience which is necessary for the programming learning. Vice versa, the learners having extroverted personality had a meaningful result on the improvement of the resilience through that personality. Through this research, we can seek after the way for the improvement of learners' resilience which mutually benefits learners having extroverted personality or introverted personality.

최근 멀티미디어를 활용한 정보표현능력 함양을 위하여 컴퓨터그래픽 강좌 개설이 증가하고 있으며, 이와 함께 해당 강좌에 대한 선행학습자가 빠르게 증가하고 있다. 하지만, 대부분 강좌는 선행학습 여부를 고려하지 않고 실행되고 있어서, 학습성취도의 저하와 컴퓨터그래픽 전문가 양성에 제약을 받고 있다. 본 논문에서는 선행학습자들의 차별된 학습 욕구를 파악하고, 구성주의 교육공학 이론에 기초하여, 선행학습 경험이 있는 학생들을 위한 강의모형의 특징과 강의교재의 특성을 제안한다.

웹 상에서 이루어진다 하더라도 수업이라는 것은 일반적인 정보를 제공하는 형태와는 구별이 되어야한다. 학습자로 하여금 능동적으로 학습에 참여하도록 하며, 학습자의 현재 상태를 고려하여 적절한 학습과제를 제공해 주기 위해서는 학습자의 특성 못지않게 지식모듈간의 관련성 또한 중요하게 고려되어야 하는 내용이다. 일반적으로 지식이라고 하는 것은 상호간의 복잡한 관계로 얽혀있는 그래프 구조인데 반해 웹 코스웨어는 대부분 교과서의 형태와 같은 트리 구조인 선형적인 흐름을 따르고 있다. 이러한 형태에서는 개별화된 학습경로 또한 제한적일 수밖에 없다. 본 연구에서는 개별화 학습의 가능성을 제시하며 코스 설계에 있어 융통적인 구성단위가 되는 학습객체를 기반으로 하여, 지식간 관련성을 고려하여 개별화된 학습경로를 제시해 줄 수 있는 코스 설계의 가능성을 찾고자한다.

컴퓨터 개별적응 검사(CAT: Computerized Adaptive Testing)란 각 학습자 수준에 적절한 형태의 검사를 개별적으로 실시함으로써 짧은 시간 안에 적은 수의 문항으로도 측정하고자 하는 제 특성을 보다 정확하고 효율적으로 측정할 수 있게 하는 기법이다. 이는 학습자 중심의 수준별 교육을 위한 학습 도구로서 이용될 수 있다. 본 연구에서는 문항반응이론 기반의 CAT를 학습에 적용시킴으로써 학습자의 평가결과에 따라 즉각적인 피드백을 통한 개별학습을 할 수 있고 일정수준의 성취단계에 이를 때까지 스스로 부족한 부분에 대한 평가를 계속 실시하여 완전학습에 도달할 수 있는 새로운 형태의 CAT 기반 학습시스템을 제시한다.

The purpose of this study was to analysis about the relationship among Cyber Home Learning System(CHLS) circumstance, learner construct, learning satisfaction in elementary school students. Base on the selected data which was gathered from Chungbuk & Deajeon elementary schools, Structural Equation Modeling was used to examine the relationship between factors. The main results of the research were as follow : First, CHLS circumstance factor was more effective on the CHLS satisfaction than CHLS learner construct. In CHLS circumstance factor, 'service' factor was more influential variable. Second, there is high correlation between CHLS circumstance factor and CHLS learner construct. In CHLS satisfaction, 'contents and design' factor was more influential variable. Third, the model fit, = 624.945 (p<.001), RMR .020, GFI .929, AGFI .878, NFI .927, CFI .930, RMSEA .102 was relatively satisfied with the standard using structural equation model. As based on this results, CHLS in elementary education needs elaborate circumstance for the effective achievement.

웹을 기반으로 한 프로그래밍 교육 시스템에 관하여 많은 연구가 이루어져 왔으나 대부분의 연구는 강의 노트의 제공 방법, 또는 하이퍼링크 상에서의 효과적인 네비게이션 방법과 같은 원격 교육 시스템에 국한된 내용이었다. 그러나 프로그래밍 교육은 그 특성상 강의노트의 제공 방법이나 하이퍼링크 상에서의 효과적인 네비게이션 방법보다도 많은 양의 과제를 통한 연습 기회의 제공과 각 과제에서의 교수자와 학습자간의 친밀하고 개인적인 상호작용이 학습자의 학업성취도에 더욱 큰 영향을 미친다. 본 논문에서는 원격 교육 시스템의 관점에서 더 나아가 교수자가 학습자에게 많은 양의 과제를 통한 연습의 기회를 부여 할 수 있고 각 과제당 교수자와 학습자간의 상호작용을 극대화할 수 있는 웹 기반 프로그래밍 교육 시스템을 구현하였다. 웹 기반 프로그래밍 교육 시스템은 학습자에게 시간과 장소에 구애됨이 없이 웹 브라우저를 이용하여 프로그램을 코딩하거나 컴파일할 수 있고 SPLINT를 통한 분석결과를 통해 즉시 피드백을 받을 수 있는 환경을 제공한다. 또한 교수자에게 많은 수의 학생들의 과제를 관리하고 교수자의 평가 기준에 의해 한꺼번에 자동으로 평가할 수 있는 환경을 제공하여 준다. 이러한 웹 기반 프로그래밍 교육 시스템은 웹을 이용한 프로그래밍 교육을 면대면 학습에 더욱 가깝게 만들어준다. 현재 웹 기반 프로그래밍 교육시스템은 K대학교 컴퓨터교육과 1학년 재학생들을 대상으로 한 C 프로그래밍 강좌에 사용되고 있다.

Programming education needs learning which is adjusted individual learners' level of their learning abilities. Recommendation system is one way of implementing personalized service. In this research, we propose recommendation method which learning items are recommended for individual learners' learning in web-based programming education environment by. Our proposed system for leveled programming education provides appropriate programming problems for a certain learner in his learning level and learning scope employing collaborative filtering method using learners' profile of their level and correlation profile between learning topics. As a result, it resolves a problem that providing appropriate programming problems in learner's level, and we get a result that improving leaner's programming ability. Furthermore, when we compared our proposed method and original collaborative filtering method, our proposed method provides the ways to solve the scalability which is one of the limitations in recommendation systems by improving recommendation performance and reducing analysis time.

This study investigated the English learners who are over 40 on their attitudes and perception for lifelong education by dividing them into age groups of middle aged and elderly learners. To this end, from May 20, 2020 to June 30, 2021, 80 participants attending lifelong education centers in North Gyeongsang province were surveyed on the demographic characteristics and interest, necessity, passion, advantage, hindrance, learning motivation, preferred subjects, and learning methods. As a result, it was found that elderly learners showed a more positive English learning attitude than middle-aged learners, and both groups considered the communication area important in their learning motivation and preferred subjects. In regard to hindrance toward English learning, different factors were shown according to the age groups along with lack of confidence in English. Differences were also shown in preferred learning methods. This study suggested the possibility of learning outcomes according to the positive learning attitude of elderly learners along with the need for detailed English program design according to learners' age.

The purpose of this study is to analyze relationship between general characteristics of learners and learner-related variables such as learning flow, self-directedness and learner satisfaction, thereby find out effective online teaching methods and provide the necessary basic data for improving learning satisfaction. A total of 473 students of medical school in C region were the subjects of this study and surveyed for research in a self-reporting form. According to the study, proportion of 31 to 40 minutes (38.9%) of learning engaged time was the highest, 65.5% of the learners studied regularly, more than those who studied irregularly(34.5%), and the higher the grade, the higher the percentage of learners who studied regularly. Learning flow averaged 4.03 (±0.86), self-directedness averaged 4.49 (±0.97), and learner satisfaction averaged 4.38 (±1.01). There were significant differences in learning flow, self-directedness and learner satisfaction according to grade, learning engaged time, and learning regularity. the factors affecting learner satisfaction were grade, learning flow, and self-directedness, with 72.5% adjusted R-squared. This study is expected to be used to establish an online learning management system to improve learning satisfaction by identifying variables related to learning satisfaction in the online learning environment of medical students.
