In this paper, we focused on training to create and optimize a basic data prediction model. And we proposed a gradient descent training method of machine learning that is widely used to optimize data prediction models. It visually shows the entire operation process of gradient descent used in the process of optimizing parameter values required for data prediction models by applying the differential method and teaches the effective use of mathematical differentiation in machine learning. In order to visually explain the entire operation process of gradient descent, we implement gradient descent SW in a spreadsheet. In this paper, first, a two-variable gradient descent training method is presented, and the accuracy of the two-variable data prediction model is verified by comparison with the error least squares method. Second, a three-variable gradient descent training method is presented and the accuracy of a three-variable data prediction model is verified. Afterwards, the direction of the optimization practice for gradient descent was presented, and the educational effect of the proposed gradient descent method was analyzed through the results of satisfaction with education for non-majors.

here are many cases that take a software education as a required course for non-major students in university curriculums. However, non-major students are experiencing various difficulties in the process of learning programming languages, and there is also the opposite opinion in terms of their effectiveness. In this study, we developed a design based software education model (DBSEM) and curriculum to solve these problems and applied it to undergraduate non-undergraduate students for the last 8 years. In the proposed method, we provide a specialized educational tool such as 'block-based programming tool', but developed 'core module' and 'concept learning module' for computational thinking and applied 'prototype design module' and coding strategy based on it. As a result, non-major undergraduates could easily learn block-based scripting tools and acquire core concepts of computational thinking.

웹 정보시스템 개발에 있어 사용자 요구사항이 복잡하고 다양해짐에 따라 웹 정보시스템 개발에 SE 기술을 접목하는 연구가 시도되고 있다. 그러나 아직 웹 기반 소프트웨어공학을 대학의 교육과정에 도입하는 경우는 없다. 본 논문에서는 웹 정보시스템의 개발 및 운영에 대한 핵심 소프트웨어공학 기법을 교육함에 있어서 중요하고 시급한 주제, 네 가지를 제안하려 한다. 첫 번째는 웹 기술과 컴포넌트 기술을 적용한 소프트웨어 아키텍처이고, 두 번째는 웹 효과적인 웹 응용 개발을 위한 디자인 패턴이며, 세 번째는 웹기반 SW 테스팅의 계획수립 및 테스트 수행 기법이고 마지막으로 웹서비스 기술과 적용 사례가 교육되어야 할 것으로 보인다.

As IT technology improves, software is being more and more important. Industry demands higher level of programming ability from university graduates. As a result, programming related courses already take higher possession of electronics department curricula. But even though the environment likewise computer laboratory is improved as much, and professors have tried to enhance the quality of their lectures and educational results, still programming education does not match the demand of our society and industry. In this paper, we introduce the overview of programming education in electronics department, KUT and discuss problems in programming language education especially for the 1st year students, since programming education to the 1st year university students becomes one of the most important part as it deals with fundamentals on programming language and we suggest its improvement directions in regards with students, teaching materials, professors, class size, and class hours.

Recently, the Internet of Things is attracting attention as an important key technology of the 4th Industrial Revolution, and SW education using physical computing is suggested as a good alternative to supplement the problems raised by beginners in programming education. Among the many teaching tools that can be used for physical computing education, MODI is a modular manufacturing tool that anyone can easily assemble like Lego. MODI is a teaching tool that can improve learners' achievement by linking a self-linked block-type code editor called MODI Studio to lay the foundation for programming in a relatively small amount of time and immediately check the results in person. In this paper, a physical computing education method using MODI was designed to be applied to basic programming courses for programming beginners and applied to after-school classes for middle school students. As a result, it was found that students' interest and satisfaction were much higher in physical computing classes using MODI than in text-based programming classes. It can be seen that physical computing education that allows beginners to see and feel the results in person is more effective than grammar-oriented text programming, and it can have a positive effect on improving basic programming skills by increasing students' participation.

The curriculum is about what to teach and learn, which is the basis for judging the level of knowledge. At the present time when the necessity of informatics education is emphasized, cultivation of human resources to actively cope with the SW-oriented society is the core of national competitiveness. The purpose of this study is to compare and analyze the quantitative aspects of high school curriculum based on higher education curriculum. Among the 18 knowledge areas, 'America' has 15 areas, 'UK' has 10 areas, and 'Japan' has 7 areas. However, 'Korea' has 6 areas, The purpose of this study is to understand the current status of Korea's information curriculum through the analysis of curriculum and to provide contents and implications for the curriculum revision.
