This study investigated the effects of varying visuals in drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=233) at a coed middle school were assigned to control, static drawing (SO), dynamic drawing (DD), static writing (SW), and dynamic writing (DW) groups. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Two-way ANCOVA results revealed that the scores of a conception test for the two drawing (SD, DD) groups and the two writing (SW, DW) groups were significantly higher than those for the control group. Within the writing groups, students of lower spatial visualization ability in the DW group scored significantly higher than those in the SW group. However, no significant differences were found in the scores of the conception test for the two drawing (SD, DD) groups regardless of students' visualization ability. Researchers also found that most students in both DD and DW groups had respectively positive perceptions of dynamic visuals in drawing or writing.

Recently SW education has been emphasized in Korea, but many students do not have many opportunities to learn computer science. In this paper, I organized a computer science show to enhance interest and understanding of computer science. The computer science show consisted of understanding binary systems, send a text message, parity bit magic, finding a number card, and collecting colors (orange games). I applied the computer science show to elementary school students and looked at the results. Most of the students who participated in computer science shows did not have an "participation experience of computer science shows". As result of surveys, many students answered "I am interesting about computer science shows," "I am interested in computer science," and "I would recommend it to my friends nearby." Through research, I learned that computer science shows are a way for elementary students to draw interest in computer science and to create curiosity and interest in computer science. I found from research that computer science shows are a way to reduce students' learning burdens and to increase interest in computer science.

In 2006, Janet Wing defined computational thinking and operated SW education as a formal curriculum in the UK in 2013. This study collected related research papers by using computational thinking, which has recently increased in importance, and analyzed it using text mining. In the first, CONCOR analysis was conducted with the keyword of computational thinking. In the second, text mining of the components of computational thinking was selected by the repr23esentative academic journals at domestic and foreign. As a result of the two-time analysis, first, abstraction, algorithm, data processing, problem decomposition, and pattern recognition were the core of the study of computational thinking component. Second, research on convergence education centered on computational thinking and science and mathematics subjects was actively conducted. Third, research on computational thinking has been expanding since 2010. Research and development of the classification and definition of computational thinking and components and applying them to education sites should be conducted steadily.

The purpose of this paper is to develop and apply instructional model to improve awareness of information accessibility for gifted students in computer science. The model applied to class is designed based on Problem-Based Learning(PBL). The class was for 42 students(22 elementary school students, 20 middle school students), and the questions, cognition of the necessity for accessibility, behavior intent for accessibility were given before and after class. Additionally, interest, satisfaction and flow were given after the class. The results of this study are as follows. Firstly, it shows a difference on the changes of cognition on the necessity and behavior intent. As a gender difference, specifically, it shows a difference on the cognition of female students's necessity and behavior intent of male students. As a class level difference, specifically, it statistically shows a meaningful difference on cognitive of the necessity of elementary school students and behavior intent of middle school students. Secondly, after class, it shows a high level of interest, satisfaction. But it shows a general level of flow, so various strategies should be developed for covering the flow level.

With the advent of the pandemic era, non-face-to-face classes are being conducted, and many studies are being conducted on the effects of non-face-to-face classes in many subjects. Since the programming class is a subject that combines knowledge transfer and practice. In the case of non-face-to-face classes, I wanted to know how students perceive them through a survey. The number of students who answered that traditional face-to-face classes were good in terms of ease of question and answer, understanding of class content and immersion in class, and more students answered that non-face-to-face classes were good in terms of securing practice time and class control. It is expected that using the results of this study will help plan effective programming lessons.

The fourth industrial revolution era calls for the ability to solve problems creatively based on basic literacy for technology. These capabilities can be enhanced through the maker education linked to SW education STEM convergence education. Meanwhile, one of the tasks that must be set prior to the maker education is to take an educational approach rather than a tech-centric approach and consider ways to stimulate interest and motivation of the participants. For this purpose, this study developed and applied an engineering-oriented Reading & Maker education program to prospective teachers so that they could participate in active making activities on their own with interest and sympathy rather than simply guiding maker activities. As a result of the study, the results of the maker education recognition survey after the application of the program showed a statistically significant improvement(p<.000).

At the beginning of the discussion of AI education in K-12 education, the study was conducted to develop and apply an AI education program based on Design Thinking and analyze the effects of the AI education programs. In the AI education program, students explored and defined the AI problems they were interested in, gathered the necessary data to build an AI model, and then developed a project using scratch. In order to analyze the effectiveness of the AI education program, the change of learner's perception of the value of AI and the change of AI efficacy were analyzed. The overall perception of the AI project was also analyzed. As a result, AI efficacy was significantly increased through the experience of carrying out the project according to the Design Thinking process. In addition, the efficacy of solving problems with AI was influenced by the level of use of programming languages. The learner's overall perception of the AI project was positive, and the perceptions of each stage of the AI project (AI problem understanding and problem exploration, practice, problem definition, problem solving idea implementation, evaluation and presentation) was also positive. This positive perception was higher among students with high level of programming language use. Based on these results, the implications for AI education were suggested.

SW education is being implemented in all the school due to the application of the 2015 Curriculum. The purpose of SW education is to improve Computational Thinking by using Unplugged Activities, Educational Programming Language, and Physical Computing. Among them, 73 domestic and 85 overseas researches related to 'Unplugged Activities' were compared and analyzed using semantic network analysis techniques. As a result, the research on 'Unplugged Activities' has been started from 1998, and the research has started in Korea since 2006. As the CT is recognized as a core competence for the future society in line with the 4th Industrial Revolution, researches have been rapidly increasing in both the domestic and overseas countries since 2016. In Korean studies, it was analyzed that many main words related to the elemental factors such as 'unplugged activity', 'robot utilization', 'educational programming language' were found. This suggests that future research should move toward research for the promotion of 'CT' which is the purpose of computer science.

Software Education will be implemented at elementary, middle and high schools starting in 2018. The goal of software education is to help students develop Computational thinking skills. Especially, using robots in software education increases student interest and helps to increase creativity. In order for software education using robots to be effective, education for teachers should be effective. The development of effective education contents for preliminary teachers can be said to be the success of software education. By the way, effective education can be said to begin with an accurate analysis of the subjects. In order to develop an effective curriculum for preliminary teachers, it is necessary to grasp the level of preliminary teachers who will carry out the software education using robots. Therefore, in this paper, we surveyed the experiences, levels and perceptions of preliminary teachers to help develop software education curriculum using robots.
