As interest in software education has increased, discussions on teaching, learning, and evaluation method it have also been active. One of the problems of software education teaching method is that the instructor cannot grasp the content of coding in progress in the learner's computer in real time, and therefore, instructors are limited in providing feedback to learners in a timely manner. To overcome this problem, in this study, we developed a software education support system that grasps the real-time learner coding situation under block-based programming environment by applying a learning analysis technique and delivers it to the instructor, and visualizes the data collected during learning through the Hadoop system. The system includes a presentation layer to which teachers and learners access, a business layer to analyze and structure code, and a DB layer to store class information, account information, and learning information. The instructor can set the content to be learned in advance in the software education support system, and compare and analyze the learner's achievement through the computational thinking components rubric, based on the data comparing the stored code with the students' code.

The purpose of this study is to examine the effectiveness of the summer enrichment programs on Korean gifted students' science learning and creativity development. This program is organized by Purdue University Gilled Education Resource Institute (GERI) in U.S.A. Researchers conducted semi-structured interview with 6 Korean students and observed 12 Korean students and GERI teachers for teacher-student interaction and teaching strategies during science-related classes. From the results, GERI program developed from Purdue 3 stage enrichment model that emphasizes creative teaching strategies, group discussions, and individual research were effective to foster creative thinking of Korean gilled students. Despite their language barriers, Korean gilled students found GERI program experience fun, creative, easy, relaxing, and thereby satisfying for their psychological and academic needs. They expected the level of stimulation in GERI program to be higher and the class to be organized more systematically; however, they reported that the broad range of topics and diverse content of GERI classes helped them develop creativity more than Korean classes. These findings will make contribution to the improvement of the quality of gifted education curriculum and programming in Korea.

The Goal of SW education is to improve computational thinking. Especially, non computer majors need to apply computational thinking to their problem solving in their fields after computational thinking class. In this paper, we verified what factors affect the improvement of computational thinking through mixed research method after teaching computational thinking to non major students. Also, we analysed the characteristics of initial learning transfer of computational thinking, and establish the reason about he validity and justification for non major in SW education. The result shows learning satisfaction, learning transfer motivation, and self-CT efficacy affect the perception about improvement of computational thinking. Also, we found that there is application of computational thinking was coming up with problem solving process because the initial learning transfer process of computational thinking has characteristics about concepts and practices of it in programming steps. The effectiveness and learning transfer process of computational thinking for non majors will give the validity and justification to teach SW education for all students.

This study aims to investigate the experiences of librarians/staff members who are responsible for facilitating makerspaces in public libraries, including their works and core competencies, their needs and experiences of training, and future plans in makerspaces. To do that, we carried out semi-structured interviews with 11 librarians/staff members and 1 library director from 7 public library makerspaces. Findings show that the participants received financial supports from the government agencies or/and relied on their library budget to run makerspaces. They identified competencies such as technology literacy, domain knowledge, teaching/programming, willingness to learn and curiosity, communication skills, leadership, and design-thinking. They have future plans for expanding spaces, purchasing equipments, program development, and so on. We believe findings could be useful for those who currently manage or plan to implement a public library makerspace by understanding practical issues and training needs in makerspaces.

The purpose of this study is to develop a contents when we are going to introduce cryptography and information security for vocational high school students. For this we do a survey of the students' level for understanding of information security and the 7th curriculum for school mathematics, 2007 revised curriculum for school mathematics, the curriculum for vocational high school, and we search for the material that connects between mathematics subjects and vocational subjects. We develop a text book that introduces information security and cryptography. After we teach vocational high school students by using this developed book, we get the result that learning cryptography with computer programming makes a good motivation of learning mathematics and roles a parameter between mathematics curriculum and vocational curriculum. As a result we propose that the developed contents can be used in 'Practical Mathematics' in the 7th curriculum for school mathematics or 'Application of Mathematics' in 2007 revised curriculum for school mathematics.

In this study, we develope a WBI(Web Base Instruction) program to do the student oriented learning using WWW and analyze the result. The 127 students who took part in the experiment were divided into two groups, an experimental group of 85 subjects and a comparative group of 42 subjects. This experiment was performed for four periods, and a formative test was conducted to measure achievement for two groups. The average and the standard deviation of scores for the experimental group are 84.9 and 16.82 respectively, and the comparative group 77.5 and 14.39. Experimental results shows that the academic achievement for the experimental group is more significant than that of the comparative group at the 0.0024(P$\le$0.05)of the result "t-test" under the 91~95$\%$ confidence interval of the level of significance. This fact says that practicing the WBI programming has an effect on the improvement of the students' academic achievement.hievement.

Smart device appeared as IT technology develops and it caused the proliferation of digital contents. It is because that App technology supports to install and use the contents in the smart device easily. App is developed by the creativity and the programming skill and the commercial value is generated in the process of development. In this paper, we taught how to develop APP to elementary school students by Android App Inventor program and observed the changes of their thinking through reflection-note which describes thinking of them. This research was carried out for 28 elementary school students, 5th and 6th grade. We found the attitude that students try to solve problem actively with the high interest. They enjoy showing developed App to others easily and quickly, which is the characteristic of smart devices. We also found a phenomenon that the students consider commercial value.

With the wide-spread use of multimedia technology, the demand for the image processing engineer is increasing in various fields. But there are few engineers who can develop practical applications in the image processing area. To teach practical image processing techniques, we need an integrated education environment which can efficiently present the image processing theory and, at the same time, provide interactive experiments for the theory presented. In this paper, we propose an integrated education environment for the image processing, which is called MTES. It consists of the theory presentation systems and the experiment systems. The theory presentation systems support multimedia data, web document and Microsoft Powerpoint$^{TM}$ file. It is tightly integrated with the experiment systems which are developed based on the integrated image processing algorithm development system, called Hello-Vision.n.

As software and artificial intelligence education became more and more important, in December 2019, the Ministry of Science and ICT announced plans to expand software and AI education to mandatory education in elementary and secondary schools by 2022. In addition to elementary and secondary schools, most universities are actively engaged in software education for computer non-majors, but research on coding education for computer non-majors is insufficient. The purpose of this paper is to find an efficient teaching and learning method for coding education for computer non-majors. Nowadays, college students, called Millennial and Generation Z, prefer visual information and are familiar with computers as digital natives. Based on these characteristics, this study examined the visual literacy and thinking styles of college students and then examined whether the students' visual literacy and thinking styles influenced coding-based problem solving in coding subjects. Based on this, this paper proposes an alternative to do programming education more efficiently for students who are new to coding.

In this paper, we implemented memristor emulator circuit on Printed Circuit Board (PCB) and observed the inherent pinched hysteresis characteristic of memristors by measuring the emulator circuit on PCB. The memristor emulator circuit implemented on PCB is composed of simple discrete devices not using any complicated circuit blocks thus we can integrate the memristor emulator circuits in very small layout area on Silicon substrate. The programmable gain amplifier is designed using the proposed memristor emulator circuit and verified that the amplifier's voltage gain can be controlled by programming memristance of the emulator circuit by circuit simulation. Threshold switching is also realized in the proposed emulator circuit thus memristance can remain unchanged when the input voltage applied to the emulator circuit is lower than VREF. The memristor emulator circuit and the programmable gain amplifier using the proposed circuit can be useful in teaching the device operation, functions, characteristics, and applications of memristors to students when thet cannot access to device and fabrication technologies of real memristors.
