정보화 사회에서는 자기 학습력 신장이 강조되고 있다. 초등사회과 교육에서 자기 학습력을 신장시키기 위해서는 다양한 학습자료의 제공을 통해 개개인의 특성에 맞게 탐구할 수 있는 탐구능력의 육성이 중요하다. 본 논문은 웹 기반 코스웨어를 개발 제작하고 이를 수업에 활용함으로써 개별학습이나 탐구학습에서 바람직한 효과를 거두는데 그 목적이 있다. 본 시스템은 단순히 텍스트와 정지된 그림만을 보여주는 기존의 웹을 활용한 학습과는 달리 Flash를 이용하여 학습자와 상호작용하여 많이 일어나도록 게임학습 위주로 구현하였으며, ASP를 이용하여 자료실, 게시판을 만들어 학습자 상호간에 적극적인 인터페이스가 이루어지도록 하였다. 연구대상은 초등학교 4학년 학생이며, 웹 기반 코스에서 활용 집단과 전통적인 방식의 학습 집단으로 구분하여 연구하였다. T검정과 분산분석을 통해 성적의 변화패턴에 차이가 있다는 것을 알 수 있었다. 이는 '문화재와 박물관' 단원을 학습하는데 있어 웹 기반 코스웨어를 활용한 학습자의 흥미와 호기심을 유발시켜 학습의욕과 교수 학습 방법을 개선하는데 기여하리라 기대되며, 전통적인 방식의 학습보다 효과적이라는 결론이다.

Recently, domestic schools are increasingly interested in environmental education related to COVID-19 and the severe climate crisis, as well as artificial intelligence education related to the 4th industrial revolution that is rapidly approaching us. In particular, AI education is highly likely to be applied to 5th to 6th graders of elementary school, so measures related to connection with 1st to 4th graders are needed. There are many students who are not proficient in computers in the lower grades of elementary school, so there may be many restrictions in using the currently used teaching aids. Therefore, this study tried to develop an artificial intelligence education program for the lower grades of elementary school to secure the linkage of artificial intelligence education. The theme of the program was developed based on the topic of environmental education, which has recently increased in interest. As for the educational method, considering the developmental stage of the lower grades of elementary school, the STEAM education method was used, which was fused with various subjects and unplugged using play and games without a computer. of the program. For validity verification, Lawshe (1975)'s content validity ratio (CVR) calculation formula was used. The verification results were analyzed to be suitable for the purpose of development of all programs. In the future, it is necessary to measure the degree of effectiveness by applying the program proposed in this study to the lower grades of elementary school.

The purpose of this study is to analyze the characteristics and problems of the content of flower design education videos on YouTube and to search for improvement direction. The subjects of analysis were 129 pieces of videos uploaded in the last one year including 'craftman floral design' as a search term. The result shows that contents covered were practical lectures, theory lectures, test related tips, job and character introduction, test work, educational guidance and publicity. The production format could be divided into studio lecture, classroom lecture, video feature, interview, Vlog, and television program. The hub-type programming strategy that periodically uploads the videos satisfying the target audiences' interests is mostly applied. The type of lecture covered 'practical skill test' got a good response from the users. Overall, content diversity, interaction between creators and users, and harmonious programming strategies are lacking. In order to improve this, it is necessary for emotional and expressive creators to pioneer differentiated fields and practice based on actual field. The introduction of interactive elements such as games and quizzes and the application of new media technologies such as VR and AR are worth trying. Three strategic types of 'hero', 'hub', and 'how to' should be applied complementary. As the demand for education content related to flower design is expected to expand in the future, it is required to develop content that can be used in various platforms, foster professional creators, and develop associated business models.

This study aims to analyze what elementary school pre-service teachers focused on and what challenges they faced in designing and producing a guided science inquiry program based on augmented reality (AR) and to provide some implications for teachers' professionalism and teacher education. To this end, focusing on the cases of pre-service teachers who designed and created AR-based guided inquiry programs, the researchers extracted and categorized the pre-service teachers' focus and challenges from the program design and production stages. As a result, in the program design stage, the pre-service teachers tried to construct scenarios that could promote students' active inquiry process. At the same time, drawing on the unique affordances of AR, the pre-service teachers focused on creating vivid visual data in a 3D environment and making meaningful connections between virtual and real-world activities. The pre-service teachers faced challenges in making use of the advantages of AR technology and designing an inquiry program due to a lack of background knowledge about CoSpaces, a content creation program. In the program production stage, the pre-service teachers tried to make their program easy to handle to improve students' concentration on inquiry activities. In addition, challenges of programming using CoSpaces were reported. Based on these results, educational implications were discussed in terms of the pedagogical uses of AR and teachers' professionalism in adopting AR in science inquiry.
