For the efficient teaching of Korean characters(Hangul) handwriting method, it needs to the collection of Hangul handwriting samples and the study of analysis methods. For the collection of Hangul handwriting samples, the students of teacher's university take part in this survey. The analysis is performed according to the characters and graphemes in Hangul. The analysis features include the number of strokes, the direction of handwriting, the relational position of graphemes, the height and width of characters, and so on. The results of this analysis will be used for the reference data for the teaching of Hangul handwritings, the study of Hangul fonts, and the research of Hangul information engineering.

본 연구는 ICT를 활용하여 수학과 교수 학습 과정안을 만드는 과정을 통하여 교원 양성기관의 교육과정에 ICT활용 교육방법의 도입과 함께 예비 수학 교사들의 ICT활용 능력을 키우고자 하는데 목적이 있다. 또한 이로써 ICT활용 교수 학습 과정안을 학교 수업에 적용함으로써 단순히 방법적 측면에서의 도구적 교체가 아닌 교육의 패러다임 변화를 통한 학습과정의 질적 개선을 추구하는데 궁극적인 목적을 둔다 수학교육론시간에 학부생을 대상으로 직접 ICT활용 교수 학습 과정안을 만들었으며 중학교 수학 1, 2학년 교과 내용을 211개의 교수학습 과정안으로 개발하였다. 이를 위하여 교과서 및 교육과정 분석 교수학습 모형정립 등의 과정을 거쳤으며 내용적 연구와 함께 과정안의 구현을 위한 기술공학적 실습 과정을 병행하였다.

This study analyzed learners' satisfaction and in-depth interviews with teachers after operating a software practical curriculum as a real-time video class for fifth and sixth graders in elementary school. The correlation between learner's presence, class overall, interaction, and real-time video class satisfaction showed that the positive correlation between presence, class overall, interaction, and satisfaction with real-time video classes was somewhat high. There were some differences in the real-time video class participation environment and real-time video class satisfaction, but it was not found to be statistically significant. In the case of teachers, it was difficult to respond to problems occurring in each student's individual environment, interactions between students, and individual feedback problems for a sluggish student. To solve this problem, opinions such as preliminary guidance and verification of real-time video class connection environment, error support for sluggish students and individual class participation environment, and feedback on individual tasks using LMS were suggested.

In this paper, a case of deep learning artificial neural network education was studied for artificial intelligence literacy education for preservice teachers and incumbent teachers. In addition, through the proposed educational case, we tried to explore the contents of artificial neural network principle education that elementary, middle and high school students can experience. To this end, first, an example of training on the principle of operation of an artificial neural network that recognizes two types of images is presented. And as an artificial neural network extension application education case, an artificial neural network education case for recognizing three types of images was presented. The number of output layers was changed according to the number of images to be recognized by the artificial neural network, and the cases implemented in a spreadsheet were divided and explained. In addition, in order to experience the operation results of the artificial neural network, we presented the educational contents to directly write the learning data necessary for the artificial neural network of the supervised learning method. In this paper, the implementation of the artificial neural network and the recognition test results are visually presented using a spreadsheet.

3D 사람 자세 추정 기술은 다양한 응용 분야에서의 높은 활용성으로 인해 대량의 학습 데이터가 수집되어 딥러닝 모델 연구가 진행되어 온 반면, 동물 자세 추정의 경우 3D 동물 데이터의 부족으로 인해 관련 연구는 극히 미진하다. 본 연구는 동물 자세 추정을 위한 예비연구로서, 3D 학습 데이터가 없는 상황에서 단일 이미지로부터 3D 사람 자세를 추정하는 딥러닝 기법을 제안한다. 이를 위하여 사전 훈련된 다중 시점 학습모델을 사용하여 2D 자세 데이터로부터 가상의 다중 시점 데이터를 생성하여 훈련하는 연역적 학습 기반 교사-학생 모델을 구성하였다. 또한, 키포인트 깊이 정보 대신 2D 이미지로부터 레이블링 된 순서 깊이 정보에 기반한 손실함수를 적용하였다. 제안된 모델이 동물데이터에서 적용 가능한지 평가하기 위해 실험은 사람 데이터를 사용하여 이루어졌다. 실험 결과는 제안된 방법이 기존 단안 이미지 기반 모델보다 3D 자세 추정의 성능을 개선함을 보여준다.

This paper explores effectiveness of integrating Problem-Based Learning with Web 2.0 technologies in Computer subject matter education for improving quality of lessons and adapting of social needs for pre-service teachers. Students have studied about computer subject matter for 4 times. The process of leaning have recorded by Web 2.0 tools that is one of the cloud services. Also the students have written reflection journals about experiences of PBL process and results. The PBL process and reflection journals have been analyzed by qualitative data analysis. Conclusions are drawn as to potential for the use of Web 2.0 tools for PBL in computer subject matter. The results of the analyses showed the following: 1) Increasing the understanding of the computer subject matter education, 2) enhancing students' competence in using ICT potentially, 3) cultivating teaching and learning strategies on Web 2.0 environment and 4) enhancing competence of future teaching activities through experiencing e-portfolio as a performance-assessment tool.

The purpose of this study is to analyze the experience of the process of developing instructional media by using Scratch for in-service teachers, after they participated in programming education with Scratch conducted as part of teaching methods using ICT. In particular, this study aimed to explore in-service teachers' thoughts and experiences of the objectives and methods integrated the programming education into their subjects creatively and convergently. To achieve the objective, they conducted an instructional design in accordance with their subject's learning goals and methods on the framework of the ASSURE model. Then, they conducted a project to develop instructional media with Scratch as part of the instructional design. 10 in-service teachers who attends the Graduate School of Education at K University in the second semester of 2019 were participated in this study. As a result, teachers showed positive expectation that the use of media developed by Scratch could bring significant results to attract students' interest and promote students' participation to lead learner-centered classes. This study has implications for future direction on programming education for professional development programs of prospective teachers as well as in-service teachers.

After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

Along with the development of technology in the fourth industrial revolution, the fields that can apply artificial intelligence technology are rapidly increasing. In order to improve computational thinking, overseas countries such as the U.S. and the U.K. are already using various AI education platforms to provide artificial intelligence education. Therefore, there is an increasing need for elementary school pre-service teachers in Korea to strengthen their AI education capabilities along with the existing software education. However, it may be difficult for learners with low levels of programming experience and AI education experience to choose an AI education platform that can sustain their learning motivation. Therefore, in this study, the factors related to learning motivation in the AI education platform were explored using the ARCS model. Through this, we present the factors required by the AI education platform for motivation and sustain of learning.
