Algorithm education that become at the base of thinking is emphasized from primary school. However, It is difficult to understand algorithm in elementary school students level. In this research, it considered curriculum that can teach universally to elementary school students by solution plan of problem. So we chose Scratch program with education data, because it is verified the effect in education of algorithm, and easy to control among EPL (Education Programming Language). It was composed curriculum so that interaction is accomplished through group activities to coincide in various level of students, and approached to the problem-solving center to emphasize important thinking process in algorithm education, and got educational value in relevant level of each student. According to validation of expert groups and surveys, we concluded the curriculum that is appropriate. The curriculum proposed in this paper can help to enhance the problem solving ability and the creativity.

The flow of computer education in modern knowledge and information society contains the computer science courses to cultivate the higher-level thinking abilities such as logical thinking skills, creativity, and problem-solving ability of learners. The purpose of this study is to recognize the need to promote the algorithmic thinking power to improve the problem solving ability of learners, to design the algorithm class based on the anchored instruction strategy for elementary school students and to verify the effectiveness. Anchored instruction model and cases are added to the class. Elementary school students were subjects and divided into a control group in which the traditional algorithm teaching method was conducted and an experimental group in which algorithm class was conducted applying anchored instruction. As results, an experimental group has shown improvements on problem solving compared to a control group.

Gifted education has drawn much attention in education in recent years and gifted education in computers in elementary education has been emerged as well throughout the country. Now computer algorithm education is considered as a core subject in the area because computer algorithm is the essence of computer technology on which information society relies technically, and also it provides theoretical basis for problem solving using computers. And we observe that fostering learner's creativity is crucial in learning computer algorithms because problem solving requires creativity in general. In the paper, we discuss the procedure to foster learner's creative problem solving ability which would greatly help students learn computer algorithms, and then we discuss how we can make algorithmic ideas into reality. Furthermore, we note that an appropriate level education is necessary for better results for outstanding students in the program, and lastly we propose ideas to improve current gifted elementary education in computers. The content of the paper is largely originated from experiences of teaching gifted elementary students conducted by a local university and sponsored by its municipal government for six years.

In this paper, we examine the effectiveness of calculation according to automation, which is one of Computational Thinking, by coding the conceptual process into Python language, focusing on the concept of divisibility in elementary school textbooks. The educational implications of these considerations are as follows. First, it is possible to make a field of learning that can revise the new mathematical concept through the opportunity to reinterpret the Conceptual Thinking learned in school mathematics from the perspective of Computational Thinking. Second, from the analysis of college students, it can be seen that many students do not have mathematical concepts in terms of efficiency of computation related to the divisibility. This phenomenon is a characteristic of the mathematics curriculum that emphasizes concepts. Therefore, it is necessary to study new mathematical concepts when considering the aspect of utilization. Third, all algorithms related to the concept of divisibility covered in elementary mathematics textbooks can be found to contain the notion of iteration in terms of automation, but little recursive activity can be found. Considering that recursive thinking is frequently used with repetitive thinking in terms of automation (in Computational Thinking), it is necessary to consider low level recursive activities at elementary school. Finally, it is necessary to think about mathematical Conceptual Thinking from the point of view of Computational Thinking, and conversely, to extract mathematical concepts from computer science's Computational Thinking.

The study analyzed effects of the problem-based learning utilizing cognitive algorithms in elementary mathematics education in terms of academic achievement and math attitude changes. In order to solve the research questions, a cognitive algorithm-based PBL model was derived based on N. Landa's algorithm-based instructional design theory. And the model was applied to a part of second semester math curriculum for 4th grade of an elementary school located in Seoul. The results showed that the PBL utilizing algorithms can be said to have effects on academic achievement. The PBL model is also considered to have positive effects in enhancing mathematical attitudes of the learners.

In 7th grade textbooks, the distributive property is generalized as in algebraic forms, and it seems that the students have not so good grip on this property. To get a good stock of knowledge on that generalized property, full understanding of it in concrete context should take precedence. This study would aim to propose some educational implications for better understanding of that property, through analysing the contents of it comparatively in Korean and Japanese elementary textbooks.

The current study explores students' views about artificial intelligence (AI) through analyses of their drawings and perceptions. The data were gathered from a total of 177 elementary school students. The constant comparative analysis was used as the data analysis method. Based on the result, the current study found that students' views about artificial intelligence were constructed into two distinct dimensions: form and relationship. The form dimension, students' views about artificial intelligence were categorized into human, household goods, machine, smart computer, electronic chip/algorithm, or the hybridized form related to the game of go such as AlphaGo. On the relationship dimension, students' views about artificial intelligence were categorized into servants, friends or enemy. Given the combination of two dimensions, the current study found two noted patterns. The first, students who viewed artificial intelligence as human form perceived artificial intelligence as a friend or an enemy. However, those who viewed artificial intelligence as non-human form perceived artificial intelligence as a servant or an enemy. Based on these results, educational implications related to the preparation of artificial intelligence era for elementary science education are discussed.

The concept of a fraction as division is a core idea which serves as a axiom in the process of a extension of the natural number system to rational number system. Also, it has necessary position in elementary mathematics. Nevertheless, the timing and method of the introduction of this concept in Korean elementary math textbooks is not well established. In this thesis, I suggested a solution of a various topics which is related to this problem, that is, transforming improper fraction to mixed number, the usage of quotient as a term, explaining the algorithm of division of fraction, transforming fraction to decimal.
