This study investigated the effect of visual mathematics education using smartphones and immediate feedback through SNS on students' understanding of basic mathematical concept and academic achievement at the tertiary level. Researchers analyzed the test results of 214 students' mid-term and final examination in 4 classes consisted of 16 weeks' classes with two hours per week. Also their 30 questionnaire survey results were analyzed. The result reveals that classes using smartphones promoted understanding mathematical concepts and induced students' motivation and affirmative reaction. This study implies that an appropriate use of technology will support dynamic visualization of mathematical modeling and its interpretation, which enables students' active participation and deeper understanding.

By using robot programming curriculums, we are able to help the learners to improve academic achievement. But these curriculums reduce the level of participation, because most of the robot programming curriculums consists mainly of understanding simple grammatical sentences. Storytelling provides a variety of educational methods to improve logical thinking of children on their experiences and offers positive learning motivations to the learners. In this paper, we proposed the robot programming curriculum using storytelling and implemented the system to support it. By using this curriculum and visualization tools in this system, children can make a robot story and model easily with others. In addition, this robot programming curriculum and system can provide learning motivation and academic achievement to the children continuously.

Educational programming languages help learners to easily understand and use computer system itself. They also enhance the reasoning power and the contemplative faculty of learners. However, in spite of the importance of educational programming languages in education, there has not been much research and development on them compared with general purpose programming languages. In this paper, we propose and examine a new educational programming environment TWo (Turtle World) which is designed for learners to utilize the recent information technologies. Aimed at being used as a learning and working tool for multimedia programming and processing, TWo is a web-based reflective object-oriented Hangul programming environment which provides each learner with the learning environment according to his intellectual ability to learn.

Among the tools based on generative artificial intelligence, the possibility of using ChatGPT is being explored. However, studies that have confirmed what factors should be considered when using it educationally based on learners' actual perceptions are insufficient. Through qualitative research method, this study was to derive consideration factors when using ChatGPT in the education. The results showed that there were five key factors as follows: critical thinking on generated information, recognizing it as a tool to support learning and avoiding dependent use, conducting prior training on ethical usage, generating clear and appropriate questions, and reviewing and synthesizing answers. It is necessary to develop an instructional design model that comprehensively composes the above elements.

자기 주위의 상황과 그 물체에 대한 직감(intutive feeling)을 뜻하는 공간감각은 수학교육의 기본적인 구성요소로서, 수학과 과학에서 다른 영역을 공부하기 위한 도구로 사용될 수 있고, 주위의 구조와 대칭성을 볼 수 있게 도우며, 모든 수학에서 창의적 사고를 지원한다. 우리나라에서도 2000학년도부터 연차적으로 실시되는 제 7차 수학과 교육과정의 도형여역에 ‘공간감각 기르기’를 신설하여 그 중요성을 강조하였다. 따라서, 본 논문에서는 미국의 공간감각 지도의 변천과 우리나라 제 7차 교육과정의 공간감각 영역의 학습 내용을 비교, 우리나라 7차 교육과정의 공간감각영역의 학습내용을 살피고, 현행 7차 교육과정에 의거 초등학교 2학년의 공간감각 영역의 교수 ${\cdot}$ 학습과정을 실제 적용, 이후 아동의 학습 추이를 살펴봄으로써, 앞으로 우리나라 초등학교 아동의 공간감각 형성을 위한 여러 가지 지도방법을 제시하고자 한다. 결론 및 제언에서는 이러한 수업으로 얻어진 결과를 토대로 하여 제 7차 교육과정에서 공간감각 영역의 적용에 대한 시사점을 몇 가지 기술하였다.

The purpose of this study was to investigate the educational usefulness, problems of smartpad-based instruction in elementary school based on qualitative research. To accomplish the purpose of the study, D elementary school in metropolitan area, two classes of digital textbook model school for seven years, were selected as the classes for observation. Six fourth and fifth graders and their teachers were interviewed and their 10 lessons were used for analyzing teaching and learning activities in smartpad-based instruction. The results of the study, 'Facilitating collaboration and interaction', 'effective use of various resource and SNS', 'improving concentrativeness', 'shortening waiting time' were identified as main educational usefulness. 'Lack of learning supporting tools', 'focusing on function rather than learning contents', 'low learning effectiveness', 'interference of flow' were presented as problems in using smartpad in classroom. Finally, some practical tasks for effective application of smartpad-based instruction were recommended.

Although many mathematical teaching/learning materials are already developed in the web, diverse utilization of this materials such as calculation, searching, or reusing of expressions are limited since the expression is actually a figure. To cope with this, MathML which describing mathematical notation was developed. In the paper, we proposed the methods of developing teaching materials using MathML, making learning assistance tools which utilize MathML, and applying MathML to information exchange community for Mathematics courses in ICT environment. Using MathML to develop a teaching material makes easy to correct and reuse the mathematical notations conveniently. Furthermore, learning assistance tools made by placing MathML help teachers reorganize and utilize these materials in the classroom as well as enhancing the connection between mathematical notations and concepts. The web-board that can make a use the mathematical notations using MathML enables the teachers and students to exchange information actively. It also helps to fulfill different types of teaching using ICT such as "discussion on the web".

At Ubiquitous ages I am teaching of the Fifth Generation Languages Program Tool which was producted by Korea at college, and it develop software program for Internet Electronic Commerce Information. In this paper I have researched the problems from education in Operating System and the Use of Tool that Korean 5GL Program Tool was better than Foreign Program Tool on functions and peculiarity, merits and demerits. I have a research and analysis of students response about the Using of Tool, Coding(Script), Application Programming in college education whose have had existing Foreign Tool. Also. I propose that the alternative plans which analyze out opinions from teaching professors and program developers.

초고속 인터넷 망의 구축에 따라 정보통신 교육이 활성화에 힘입어 직.간접적으로 응용하기 위한 노력이 지속적으로 진행되어 왔다. 웹 기반 원격강의는 원거리 학습자들의 학습욕구를 자기 주도적인 학습이 되도록 전체적인 수업을 진행하므로 학습과정에서의 질의 응답을 교수자에게 면대면으로 제공하지 못하였다. 따라서 학습자가 요구한 질의 내용을 잘못 이해함에 따라 교수자가 학습과정에서의 피드백 제공을 하지 못함으로써 개인학습의 동기부여가 감소됨에 따라 흥미를 입게 되었다. 따라서, 본 논문에서는 웹 기반 서비스에 대한 체계적인 분석 및 설계를 위해 네비게이션 모델을 통해 질의 응답을 지원하는 QALT(Question Answer Learning Tool)를 설계 및 구현한다. 원격강의는 웹 상에서 기본적인 컨텐츠를 제시하고 그를 통해 수업이 진행되는 과정에서의 질의 응답의 문제점을 개선하기 위해 일다대(One-To-Many)의 서비스를 제공한다. 또한. 학습자는 교수자가 지정한 교육용 서버를 통해 텍스트 형식이 아닌 강의자료로 쓰인 문서파일에 직접 작성하여 질의 응답을 가능하게 된다. 그로 인해 교수자와 학생간의 질의 응답을 통해 상호작용을 원활하게 할 수 있는 보조학습도구로써의 사용이 증가될 것이다. 또한 서버에서의 폴더 서비스와 메일링 서비스를 통해 실시간 질의 응답이 가능함으로써 학습자는 강의파일에서 그림에 관한 질문에 효과를 볼 수 있고 교수자는 질문 받은 내용의 위치를 시각적으로 쉽게 볼 수 있으므로 빠른 응답이 가능하게 될 것이다.

This purpose of this study is to develop and apply the physical computing lessons based on the software guidelines from the Ministry of Education (2015). In this study, I research how computational thinking occurs in class by applying the physical computing lessons to elementary students based on computational practices. The physical computing lessons and analytic methods for computational thinking in this study can be used as a sample and case-study to develop the lessons in the educational field.
