Since 2019, the informatics education is being conducted for elementary school 5th, 6th grade students through the curriculum revised 2015. But, informatics education is implemented from the lower grades of elementary school in many countries. The purpose of this study was to suggest the direction in the choice of programming language considering characteristics for lower grades student. In order to achieve the goal, evaluation criteria were developed considering the development characteristics of lower grades and necessary elements of educational programming language. The results of analyzing the usability of the two languages based on the criterion are as follows. First, Viscuit can be used to consider the expressive power of students with lower school age or to learn algorithms without learning about programming concepts. Second, ScratchJr is easy to learn the concept of algorithm and programming.

With the development of artificial intelligence, society is moving to a different world. As a result, amid growing interest in artificial intelligence education, research on how to teach artificial intelligence is also being conducted more actively in Korea. However, a lot of research is being conducted around the upper grades of elementary school, and curriculum and programs for the lower grades are insufficient. Therefore, this study developed an artificial intelligence program for lower grades. Among them, it was developed focusing on artificial intelligence image recognition. It compares image recognition methods of people, animals, and computers, identifies the characteristics of fallen leaves, and helps them understand the image recognition process of artificial intelligence by classifying them according to the characteristics of fallen leaves. I hope this program will help elementary school students understand the image recognition principle of artificial intelligence in the future.

Mathematical justification is essential to assert with reason and to communicate. Students learn mathematical justification in 8th grade in Korea. Recently, However, many researchers point out that justification be taught from young age. Lots of studies say that students can deduct and justify mathematically from in the lower grades in elementary school. I conduct questionnaire to know awareness and steps of elementary school students and middle school students. In the case of 9th grades, the rate of students to deduct is highest compared with the other grades. The rease is why 9th grades are taught how to deductive justification. In spite of, however, the other grades are also high of rate to do simple deductive justification. I want to focus on the 6th and 5th grades. They are also high of rate to deduct. It means we don't need to just focus on inducing in elementary school. Most of student needs lots of various experience to mathematical justification.

Objectives: In this study, knowledge of environmental disease, experience of environmental health education and necessity of environmental health education of elementary school pupils were compared and analyzed. Methods: The population of this study was from grade 1 to 6 elementary school pupils in Ulsan city, Korea. Five elementary schools were randomly selected from Ulsan City. Seven hundred and twenty-eight responses from the five schools were analyzed (seventy-two were excluded). A self-administered questionnaire measuring sociodemographic variables, Knowledge of environment related disease(atopic dermatitis, asthma etc), as well as educational experience and necessity of environmental health education was analyzed. The survey results were analyzed using SPSS-PC Program 12.0 and the following results by implementing Frequency Analysis, Cross-tabulation Analysis and ANOVA are as follows. Result: Pupils of lower grades more informed than those of higher grades about atopic dermatitis. Among asthma sufferers, many responded that symptoms occurred or improved during the lower grades of elementary school. In terms of the lifestyles of patients with atopic dermatitis or asthma, female pupils, especially those in the lower grades, tended to make changes in their daily habits based on their disease. Also, parents tended to intervene/mediate more in the dietary habits and personal hygiene habits of lower-grade pupils compared to their higher-grade counterparts. Personal hygiene education is currently not provided in schools, and upper-grade pupils have more experience with personal hygiene education compared to lower grade pupils. 430 (59.0%) of pupils replied that education about personal hygiene is necessary in their curriculum. 490 (67.3%) of elementary pupils are aware of the close connection between education in hygiene and human health. When asked if education in hygiene should also be undertaken by teachers and parents, 406 (55.7%) students said that it should be done. Conclusions: Developing a concrete health education program and raising instructors' awareness of the necessity for education in hygiene.
