To learn mathematics effectively, understanding vocabulary is essential. Accordingly, as a way to present vocabulary for mathematics education, high-frequency vocabulary was extracted from the 2009 revised 1st and 2nd grade mathematics textbooks and the 2015 revised 1st and 2nd grade mathematics textbooks. At this time, mathematics textbooks were analyzed by grade and semester, and vocabulary with a common frequency of 5 or more was extracted. In order to use it effectively in school settings, common vocabulary for each grade and intensive vocabulary for each semester were presented. As a result of the study, 61 vocabulary words for first grade education and 121 vocabulary words for second grade education were selected. As a result of analysis by vocabulary level, various levels of vocabulary from grades 1 to 5 were used. As a result of analysis by vocabulary type, the proportion of academic words increased similarly, but the proportion of technical words was found to be highest in the first semester of the second year. Based on these results, the extracted vocabulary for mathematics education is used as a resource for vocabulary instruction for students' mathematics education in each grade to help students learn mathematics.

We often need to include categorial variables as explanatory variables in regression models. The categorial variables in regression models can be quantified through dummy variables. In this study, we provide an education tool using Excel VBA for displaying regression lines along with test results for regression models with a continuous explanatory variable and one or two categorical explanatory variables. The regression lines with test results are provided step by step for the model(s) with interaction(s), the model(s) without interaction(s) but with dummy variables, and the model without dummy variable(s). With this tool, we can easily understand the meaning of dummy variables and interaction effect through graphics and further decide which model is more suited to the data on hand.

로봇기술의 진화적 측면을 고려하여 아동을 대상으로 하는 로봇 개발이 많이 이루어지고 있으며, 최근에는 교육적 활용 도구로서 현장 연구도 활발히 이루어지고 있다. 로봇의 얼굴은 인간과 로봇의 상호작용의 시작이라고 할 수 있는 중요한 부분이나, 아직 로봇 얼굴에 대한 체계적인 분석 연구는 매우 부족하다. 따라서 본 연구에서는 아동 교육용 로봇 또는 홈 로봇에 적당한 얼굴 설계 가이드를 제시하기 위하여, 많은 로봇 얼굴을 대상으로 아동들의 인지 분포와 로봇 얼굴의 계량 수치를 분석하였다. 그 결과 아동들은 로봇얼굴의 색깔에 유의한 영향을 받는 것으로 나타났으며, 로봇 얼굴에서 아동의 선호도에 가장 큰 영향을 끼치는 부분은 아동의 성별 간 유의한 차이는 있었지만 얼굴형과 눈이었다. 즉, 아이와의 상호작용에 긍정적 영향을 줄 것으로 기대되는 로봇은 동글 넓적한 얼굴의 큰 눈과 비교적 작은 입으로 나타났고, 비대칭이거나 긴 타원형의 얼굴을 싫어하는 경향을 보였다.

수학은 기초학문으로서 합리성과 창의성을 기르는 중요한 과목이다. 하지만 학생들에게는 어렵고 두려운 과목으로 되어가는 게 현실이다. 한편 STEM은 학문 간의 벽을 허물고 서로 융합하여 과학, 수학, 공학, 기술 등의 과목에 흥미도를 높이기 위한 대안적 교육이다. STEM교육의 도구로 로봇이 효과적인 것으로 연구되어 있다. 따라서 STEM 기반의 로봇교육을 하여 수학에 대한 흥미도를 높이고자 수학학습프로그램을 개발하였다.

Due to COVID-19, most schools are conducting online learning. In this study, a total of 12 block-type educational programming tool classes were conducted in the form of online learning for 6th grade elementary school students, and then quantitatively and qualitatively analyzed students' perceptions of their learning experience on entry learning. As a result of the analysis, it was found that the learner easily recognized the use of the entry program and the difficulty of learning contents, and the learning satisfaction was high. When students face difficulties, it was found that they received the most help from the hint function provided by the site itself, and they were found to be less aware of the necessity of teachers when learning entry. As a result of the qualitative analysis, it was found that the learner felt a lot of novelty and fun through easy and simple operation. On the other hand, it was found that the learning contents and hints were not understood, which made them difficult and felt that the hint contents were insufficient. It was found that students felt a sense of accomplishment by creating and manipulating programs as they wish.

The Code Block Based Educational Programming Language(EPL) is the mainstream tool for software education for elementary students. However, Code Block Based EPL has limitations in scalability, even though there are many advantages as an introductory tool for software education. In this study, we searched the approach of SW education using Python, which is a text-based programming language actively used in real industrial field. We developed a learning program and model using Python and applied it to the sixth grade elementary school students for 10 hours. As a result, we found that the robot-based Python learning model had a significant effect on improving students' thinking skills and confirmed the applicability of text-based programming language to elementary school students.

The purpose of this study is to analyze the perception and need of the early childhood education field on authentication of teaching materials and implements for young children. To achieve this, a survey was carried out on 350 teachers and directors in Daejeon-based kindergartens and child-care centers from September 21 to September 30, 2013. The results of the analysis are as follows. First, 59.4% of them thought that it needed the evaluation authentication of teaching materials and implements for young children. 32.9% of them had a high perception of the early childhood education field. 39.4% of them had high need of the early childhood education field. And 45.1% of them expected a high effect of introducing the evaluation authentication system of teaching materials and implements for young children. Second, most of them had the highest need of the evaluation authentication of teaching materials and implements for young children in terms of education, followed by function and field. And most of them placed the highest emphasis on social development, safety and language in terms of education, function and field, respectively. Consequently, the use of teaching materials and implements, which the social development and safety in terms of education and function are respectively evaluated and authenticated by the diversity of teaching materials and implements for young children, has need of the high evaluation and authentication of teaching materials and implements that can guarantee the quality when young children use a lot of experiment and observation implements such as block play, reading materials, manipulating materials, making implements.

본 논문에서는 초등학생을 위한 교육용 3D 골드버그 장치 애플리케이션을 개발하였다. 골드버그 장치는 창의력 증진을 위해 많이 제작한다. 하지만 골드버그 장치를 제작하기 위해서는 넓은 장소와 많은 도구가 필요해서 비용이 부담된다. 그래서 애플리케이션으로 개발하여 부담을 줄이고 실제로 골드버그 장치를 제작하는 것처럼 하기 위해 Unity 3D 엔진을 이용하여 3D와 물리법칙을 적용했다. 개발한 애플리케이션은 교육 프로그램에서 활용하여 초등학생의 창의성 증진, 물리법칙 이해, 공학적 설계능력 향상, 수학적 사고력 향상에 도움이 될 수 있다고 생각한다.
