In the existing curriculum of the Elementary Computer Education, it is hard to improve the CPS(Creative Problem Solving) skill and logical thought since the 7th national curriculum emphasizes application programs and CAI softwares. To complement this drawback, it is required to teach the principal of the computer science but there is not many researches for what problems of teaching computer science exist and what the response of students are. Thus, we carried out a research to know whether the students of elementary school can understand principal of computer science in the field of subject matter education. We found that the students can learn the principle of Saving Bitmap Image if the class level is adjusted properly.

Given the flow matrix, plant size (rectangle shape) and department sizes, the algorithm in this paper provides the plant layout with rectilinear distance measure. To construct automated facility design, eigenvector approach is employed. A branch and bound computer code developed by Tillinghast is modified to find the feasible fits of departments without shape distortion (see [1])in the plant rectangle. The computational results compared with CRAFT are shown.

A whole society has become software-driven and each independent fields has become convergence based on computing as the new digital economy era has come. This change affect computational literacy using computational thinking is emphasized the importance as the core competence for the future living. It means that supply of manpower with understanding software principle will decide the fate of the country. For this reason, each country are reinforcing computer science education or computing education. In this paper, we researched and analysed on new global trends of computer education in school especially focused on national curriculum and policy.

In this paper, we conducted a case study for lower grade elementary school students by modifying and applying lesson plan of CS Unplugged v4.1. Software education was introduced in the 2015 revised national curriculum in Korea, but the starting age is later than the other countries. Also most projects and researches are concentrated in higher grade elementary school students. It is necessary to lower the entry age of software education in order to nurture human resources leading the fourth industrial revolution era. In this study, we modified the lesson plan of CS Unplugged v4.1 to be suitable for lower grade elementary school students in Korea. The participants were 18 students in the first grade of elementary school, pre&post-test on understanding of computer science principles were conducted for examining the effectiveness. As a result, the average was significantly higher in the post-test than in the pre-test, with t=-2.222, p=0.040(p < .05).

Computer in one of the most tremendous achievements of the modern scientific technique. Not only in government, business, research and education but in our daily life. computers are widely utilized to assist in solving various problems. With increasing frequency, it is recognized that a right understanding of the computer is necessary: naturally, this recognition places a great emphasis on the computer education. In Korea computer is chosen either as an optional subject or as a kind of group activity in many schools. It is the purpose of this study to compare and analyze the internal sorting algorithms which are used frequently in data processing. and to present the results of program analysis. which will make it possible to choose the appropriate sorting algorithm for each data processing. Generally the algorithms are coded in a language appropriate for structured programming. like PASCAL: however, here the algorithms are expressed in BASIC which is widely used with the personal computers so that the students and the teachers may understand them easily.

In this paper, we propose an efficient repository model for online software education. The software education of app development consists of 7 stages: coding & debugging, submit, collaboration, review, validate, deployment, certification. Proposed repository model supports all 7 stages efficiently. In the coding & debugging stage, the students repeat coding and debugging of source. In the submit stage, the output of previous process such as source codes, project, and videos, are uploaded to repository server. In the collaboration stage, other students or experts can optimize or upgrade version of source code, project, and videos stored in the repository. In the review stage, mentors can review and send feedbacks to students. In the validate stage, the specialists validate the source code, project, and the videos. In the deployment stage, the verified source code, project, and videos are deployed. In the certification stage, the source code, project, and the videos are evaluated to issue the certificate.

오늘날 요구되는 새로운 인재 교육을 위하여 초 중등학교에 다양한 테크놀로지를 수업에 도입하고자 하는 시도가 이루어지고 있다. 본 논문에서는 현직 초 중등학교 교사 37명을 대상으로 테크놀로지를 도입한 과학수업에 대한 인식을 조사하였다. 연구 결과, 대부분의 교사들은 과학 수업에서 테크놀로지를 도입하는 것의 효과를 인식하고 있었으나, 구체적으로 실행할 방법적인 측면에서 고민하고 있는 것으로 나타났다. 따라서 앞으로 테크놀로지를 활용한 과학 교수법을 개발하고, 이를 효율적으로 활용할 수 있도록 교사들의 수업전문성을 발달시킬 교사 교육 프로그램 개발에 대한 후속연구가 필요하다.

미래 변화에 대응하는 역량으로 디지털 리터러시가 제시되고 있다. 국내에서는 2022 교육과정 개정의 중점 사항으로 미래 변화에 대응하는 역량으로 디지털 기초 소양을 강화한다. 한편 코로나19로 원격수업이 확대되면서 LMS(Learning Management System)의 사용이 증가하였다. LMS는 디지털 기기, 소프트웨어를 활용하므로 디지털 리터러시를 함양할 수 있는 기회가 될 것이다. 본 연구에서는 학교 현장에서 활용되는 Microsoft의 Teams, Google의 Classroom, KERIS의 위두랑과 e학습터를 비교하고 디지털 리터러시 내용 요소와 LMS 기능을 관련지어 활용방안을 제시하였다. 본 연구를 통해 LMS를 활용하면서 디지털 리터러시를 기를 수 있을 것으로 기대된다.

2015 개정 교육과정에서는 미래 사회의 인재를 육성하기 위해 중학교에 정보 교과를 필수화하였다. 이를 지도할 정보·컴퓨터 교사를 확보하기 위해 비 정보과 교사를 대상으로 부전공연수를 실시하여 정보 교육을 할 수 있는 자격을 부여하고 있다. 이들은 일반 학습자와 다르게 교육학적 지식과 역량은 높으나, 내용 지식은 컴퓨터과학의 초보자 수준이다. 이러한 학습자의 특성을 고려하여 마이크로비트를 활용한 연수를 12차시 동안 진행하였고, 이는 비 정보과 교사의 프로그래밍 자아효능감에 긍정적인 영향을 준다는 것을 확인할 수 있었다. 그러나 본 연구는 단일집단에게 실험을 실시하였으므로 그 효과를 일반화하는 데 한계가 있다. 따라서 후속 연구에서는 비교 집단을 설정하는 실험 설계로 교육 효과를 검증할 필요가 있다.
