The purpose of this research is to develop a probability program based on the actual condition of understanding of probability by the elementary school students from 3rd to 6th grade and search for ways to apply it to the 3rd grade of elementary school students. Based on the results from the research, the author reached a conclusion as following. After applying the learning program to five students of 3rd grade, all of the five students made progress understanding the concept of experimental and theoretical probability. However, for understanding the concept of example space, only two leading students were improved, which shows that students are having much difficulty in understanding the concept. As for under-standing the concept of experimental probability, many students gained the conceptual difference between the experimental and theoretical probability after using the program and enhanced their understanding of experimental probability.

This study aims to find meaningful implications for the development of Korean elementary school math education courses and textbooks by comparing and analyzing the number and arithmetic areas of Korean and Canadian math textbooks in fifth and sixth grades. To this end, the textbook composition system of Korean and Canadian elementary schools was compared and analyzed, and the number and timing of introduction of math textbooks and math textbooks by grade, and the number in fifth and sixth grade and the learning contents of math textbooks were compared and analyzed. The following conclusions were obtained from this study: First, it is necessary to organize a textbook that can solve the problem in an integrated way by introducing the learned mathematical concepts and computations naturally in the context of problems closely related to real life, regardless of the type of private calculation or mathematics area. Second, it is necessary to organize questions using materials such as real photography and mathematics, science, technology, engineering, art, etc. and to organize textbooks that make people feel the necessity and usefulness of mathematics. Third, sufficient learning of the principles of mathematics through the use of various actual teaching aids and mathematical models, and the construction of textbooks focusing on problem-solving strategies using engineering tools are needed. Fourth, in-depth discussions are needed on the timing of learning guidance for fractions and minority learning or how to organize and develop learning content.

The purpose of this study is to examine the vertical and horizontal continuity between grades and publishers, respectively, by analyzing the readability of reading passages included in English textbooks for 5th and 6th grades of elementary school. In order to do so, a corpus was constructed with the reading passages contained in 10 textbooks, and the reading passages in each textbook were analyzed through Coh-Metrix. Also, it was examined whether there was a statistically significant difference between grades and publishers in readability through one-way ANOVA. The results are as follows. First, as a result of analyzing the difference in readability between publishers within the same grade, there was a statistically significant difference between fifth-grade textbooks in the L2 readability index. Second, as a result of analyzing the vertical continuity between grades within the publisher, the difficulty of textbook A was higher in grade 6 than grade 5 based on FRE and FKGL, which showed a statistically significant difference. On the other hand, when L2 readability was used as the standard, the difficulty of textbook B was lower in 6th grade than in 5th grade. This result seems to be because FRE and FKGL calculate readability based on sentence and word length, whereas L2 readability is based on content word overlap, word frequency, and syntactic similarity of sentences.

In this study, we investigated the elements of knowledge and information processing competence of science inquiry activities in grades 3-6 science textbooks. For this purpose, the elements of knowledge and information processing competence were extracted and a framework for analysis was created. Analysis of eight science textbooks for grades 3-6 in elementary school was carried out using the analysis framework. The following results were obtained by the analysis framework: First, we divided the knowledge and information processing competence into five elements: 'collection,' 'analysis,' 'expression,' 'selection,' and 'evaluation.' Second, the elements of knowledge and information processing competence of science inquiry activity of elementary science textbooks were not evenly composed. The science inquiry activities of elementary science textbooks focused on 'collection' and 'analysis' among the five elements of the knowledge and information processing competence, followed by 'expression,' 'selection,' and 'evaluation.' As a result, we found that a science inquiry model or a science instruction model is needed to develop the knowledge and information processing competence in elementary school science curriculum.

Recently, domestic schools are increasingly interested in environmental education related to COVID-19 and the severe climate crisis, as well as artificial intelligence education related to the 4th industrial revolution that is rapidly approaching us. In particular, AI education is highly likely to be applied to 5th to 6th graders of elementary school, so measures related to connection with 1st to 4th graders are needed. There are many students who are not proficient in computers in the lower grades of elementary school, so there may be many restrictions in using the currently used teaching aids. Therefore, this study tried to develop an artificial intelligence education program for the lower grades of elementary school to secure the linkage of artificial intelligence education. The theme of the program was developed based on the topic of environmental education, which has recently increased in interest. As for the educational method, considering the developmental stage of the lower grades of elementary school, the STEAM education method was used, which was fused with various subjects and unplugged using play and games without a computer. of the program. For validity verification, Lawshe (1975)'s content validity ratio (CVR) calculation formula was used. The verification results were analyzed to be suitable for the purpose of development of all programs. In the future, it is necessary to measure the degree of effectiveness by applying the program proposed in this study to the lower grades of elementary school.

This study is to recognize importance of casing anxiety on mathematics for underachievers and to examine a plan to solve a problem with anxiety, by analyzing factors which make underachievers anxious on the mathematics. First, we analyze factors which make mathematical underachievers anxious on the mathematics. Second, we compare and analyze a level of anxiety on the mathematics and factors which cause anxiety on the mathematics according to their grade and gender. This study's participants were 308 mathematical underachievers at 4th, 5th, and 6th grade, studying at six different elementary schools in three different areas. The results of factors which make mathematical underachievers anxious on the mathematics obtained from the survey are as follows. First, in the top-category factor, mathematical underachievers are influenced by following factors in order, which are a mathematic subject, learner's attitude, environment, and a teacher. Second, in the factor of making students anxious on the mathematics according tn their grade, although the mathematic anxiety of students at 6th grade is higher than students at 4th and 5th grade, in the anxiety differences between the different grades. Third, in the factors which make the students anxious on the mathematics according to their gender, female students show more anxiety than male students. In summary, an anxiety of the underachievers at the elementary schools are different in the top and sub-category factor, according to their grades and their gender. It is shown that the underachievers feel more anxiety compared to normal elementary schools, and therefore the anxiety on the mathematics is one of the causes of under-achievement of the mathematics.
