As the world enters the era of the Fourth Industrial Revolution, which is represented by advanced technology, it not only changes the industrial field but also the education field. In recent years, Smart Learning has enriched learning by using diverse forms and technologies that utilize vast amount of information about learners' individual knowledge through the emergence of realistic and intelligent contents that combine high technology such as artificial intelligence, big data and virtual reality and there is an increasing interest in intelligent adaptive learning, which can customize individual education. Therefore, the purpose of this study is to explore intelligent adaptive learning method through recent smart education environment, beyond traditional writing-based communication education which is highly dependent on the competency of instructors. In this study, we analyzed the various learner information collected in the communication course and constructed a concrete teaching and learning method of intelligent adaptive learning based on the instructor's intended smart contents. The result of this study is expected to be the basis of highly personalized teaching and learning method of digital method in communication education which is emphasized in the fourth industrial revolution era.

디지털 기술 발달은 우리의 삶뿐만 아니라, 온라인 교육 환경에도 많은 변화를 가져오게 되었다. 개별 학습자들에게 맞춤화된 내용을 필요한 즉시 제공 받기를 원하는 학습자들의 요구에 따라 마이크로러닝이 등장하게 되었다. 마이크로러닝은 개인에게 맞춤화된 콘텐츠를 적시에 빠르게 학습이 제공된다는 의미에서 '적응형(adaptive)' 교육이라고 할 수 있다. 이에 본 연구에서는 적응형 마이크로러닝의 개발원칙이 무엇인지 살펴보고자 하였다. 이를 위해 문헌 연구 및 사례 분석을 통해 적응형 마이크로러닝 개발원칙을 탐색하였다. 그 결과, 개발원칙을 적응형 학습 환경, 적응형 학습 콘텐츠, 적응형 학습 시퀀스, 적응형 학습 평가의 네 가지 측면으로 구분하고 각각에 대한 세부요소를 제시하였다. 마이크로러닝이 현 사회적 요구를 반영한 새로운 이러닝의 형태인 만큼, 본 연구는 앞으로의 후속연구를 위한 방향성을 제안하는 탐색연구로서의 의미를 찾고자 한다.

The knowledge-based society of the 21st century requires effective education and learning methods in each professional field because the development of human resource determines its competence more than any other factors. It is highly desirable to develop an intelligent tutoring system, which meets ever increasing demands of education and learning. Such a system should be adaptive to each individual learner's demands as well as the continuously changing state of the learning process, thus enabling the effective education. The development of a learning environment based on learner modeling is necessary in order to be adaptive to individual learning variants. An intelligent learning environment is being developed targeting the heritage education, which is able to provide a customized and refined learning guide by storing the content of interactions between the system and the learner, analyzing the correlations in learning situations, and inferring the learning preference from the learner's learning history. This paper proposes a heritage learning system of Bulguksa temple, integrating the ontology-based learner modeling and the learning preference which considers perception styles, input and processing methods, and understanding process of information.

This paper presents adaptive learning data of evolvable neural networks (ENNs) for time series prediction of nonlinear dynamic systems. ENNs are a special class of neural networks that adopt the concept of biological evolution as a mechanism of adaptation or learning. ENNs can adapt to an environment as well as changes in the environment. ENNs used in this paper are L-system and DNA coding based ENNs. The ENNs adopt the evolution of simultaneous network architecture and weights using indirect encoding. In general just previous data are used for training the predictor that predicts future data. However the characteristics of data and appropriate size of learning data are usually unknown. Therefore we propose adaptive change of learning data size to predict the future data effectively. In order to verify the effectiveness of our scheme, we apply it to chaotic time series predictions of Mackey-Glass data.

This study focused on the developing a system of computer adaptive diagnosis and instruction(CADI). This system is a conceptual model that connected learning with assesment by using new media such as computers, multimedia, and new technologies. In this conceptual model, adaptive diagnosis means tailored or customized diagnostic evaluation, and adaptive instruction implies tailored or customized instruction. The connection between learning and assesment suggests that they are closely related to determine following learning contents and learning methods. CADI's expected effect are 1) it can contribute to real learning of core concept, 2) it can enlarge the educational opportunities, 3) it can help students study by student himself and learn media literacy, 4) information for evaluation functions more essential roles, 5) it is possible to work cooperatively with any other school subject.

지식기반 환경의 변화와 더불어 이-러닝은 매우 보편화된 교수.학습 방법의 하나가 되었으며, 이와 관련한 여러 연구들이 진행되고 있다. 이-러닝의 주요 연구 분야 중의 하나는 학습자의 다양한 상황들을 반영하여 학습자 개개인의 특징에 맞게 학습내용을 지원하기 위한 적응형 학습 시스템에 관한 연구이다. 이와 관련하여 최근에는 적응적 학습내용을 보다 효과적으로 지원하기 위하여 온톨로지를 기반으로 한 적응형 학습 시스템에 대한 연구들이 활발히 진행되고 있다. 본 논문에서는 FCA의 개념 망을 기반으로 온톨로지의 접근 방법과 목적은 같이하지만, 특정 영역의 학습에 적합한 사용자가 보다 자유롭고 쉽게 자신의 적응형 학습 시스템을 구축하여 사용할 수 있는 적응형 학습 시스템을 설계하여 제안한다. 제안된 시스템은 학습영역에 존재하는 학습객체와 학습개념들 사이의 연관 관계에 따라 이들을 개념 망 구조 안에 자동으로 계층화한다. 또한 학습자의 지식수준, 학습선호도, 학습스타일 및 학습개념의 학습상태에 따라 개념 망 학습구조를 적응적으로 구성하여 제시한다.

This paper presents that TD method is applied to the human adaptive devices for smart home with context awareness (or recognition) technique. For smart home, the very important problem is how the appliances (or devices) can adapt to user. Since there are many humans to manage home appliances (or devices), managing the appliances automatically is difficult. Moreover, making the users be satisfied by the automatically managed devices is much more difficult. In order to do so, we can use several methods, fuzzy controller, neural network, reinforcement learning, etc. Though the some methods could be used, in this case (in dynamic environment), reinforcement learning is appropriate. Among some reinforcement learning methods, we select the Temporal Difference learning method as a core algorithm for adapting the devices to user. Since this paper assumes the environment is a smart home, we simply explained about the context awareness. Also, we treated with the TD method briefly and implement an example by VC++. Thereafter, we dealt with how the devices can be applied to this problem.

This study introduces the process and results of developing an adaptive math learning program for self-directed learning. It presented the process and results of developing an adaptive math learning program that takes into account the level of learners using artificial intelligence. We wanted to get some suggestions on developing programs for artificial intelligence-based mathematics. The program was developed as Math4U, an application based on smart devices in the "character and expression" area for 7th grade. The Application Math4U may be used differently depending on its purpose. It is also expected to be a useful tool for providing self-directed learning to students as the basis for educational research using smart devices in a changing educational environment.
