  • This study investigated and compared orientations toward scientific inquiry learning among general and science-gifted elementary students. It also investigated and compared the relationship between their orientations toward scientific inquiry learning and their coping strategies for anomalous situations. To realize this, 61 general elementary students and 53 science-gifted elementary students in Seoul were selected, and questionnaires were administered to investigate their orientations toward scientific inquiry learning and coping strategies for anomalous situations. In addition, semi-structured in-depth interviews were conducted individually with some of the general and science-gifted students. The results showed that among orientations toward scientific inquiry learning, regardless of grade level, the general students were most likely to possess 'concept understanding' and second most likely to exhibit 'scientific practice'. On the other hand, the science-gifted students demonstrated the highest frequency of 'scientific practice', with 'concept understanding' and 'complexity' also being relatively common. 'Activity driven' was found only among some of the general students and 'engineering practice' was found only among some of the science-gifted students. 'Process skills' were not found. No clear relationships between orientations toward scientific inquiry learning and coping strategies for anomalous situations were found. However, some differences in the choice of coping strategies for anomalous situations between the general and science-gifted students were discovered, even when they had the same orientations toward scientific inquiry learning. The educational implications of these findings were discussed.

  • This study is tried in order to link informal arithmetic reasoning to formal algebraic reasoning. In this study, we investigated elementary school student's non-formal algebraic reasoning used in algebraic problem solving. The result of we investigated algebraic reasoning of 839 students from grade 1 to 6 in two schools, Korea, we could recognize that they used various arithmetic reasoning and pre-formal algebraic reasoning which is the other than that is proposed in the text book in word problem solving related to the linear systems of equation. Reasoning strategies were diverse depending on structure of meaning and operational of problems. And we analyzed the cause of failure of reasoning in algebraic problem solving. Especially, 'quantitative reasoning', 'proportional reasoning' are turned into 'non-formal method of substitution' and 'non-formal method of addition and subtraction'. We discussed possibilities that we are able to connect these pre-formal algebraic reasoning to formal algebraic reasoning.

  • This study aimed to analyze the moderated effects of mathematics test-preparation strategies in the relation between elementary school students' epistemological beliefs about mathematics and test anxiety. The moderated effects were tested by using structural equation modeling with the Ping's two-step approach. The subjects were 810 6th graders (411 male, 399 female) from 13 elementary schools situated in G Metropolitan City. Tests for epistemological beliefs about mathematics, test anxiety, and mathematics test-preparation strategies were used as measurement scales. The results of this study were as follows. The moderated effects of mathematics test-preparation strategies in the relation between epistemological beliefs about mathematics and test anxiety were statistically significant. Higher level of epistemological belief about mathematics were linked to lower level of test anxiety, while lower level of epistemological belief about mathematics led to an increased influence of test-preparation strategies levels on test anxiety. Students who had higher levels of epistemological belief about mathematics displayed lower level of test anxiety when using high levels of test-preparation strategies. Students who scored lower in the epistemological belief about mathematics had lower level of test anxiety when employing low levels of test-preparation strategies. Therefore, to lower the level of test anxiety among elementary students, the intervention program need to consider the appropriate levels of test-preparation strategies in accordance with each student's level of epistemological belief about mathematics.

  • 초등학교 인공지능(Artificial Intelligence, AI) 교육은 학교급별 특성과 수준을 고려하여 놀이 및 체험 활동 중심으로 계획되고 있다. 그러나 교육 현장의 수요 및 AI 리터러시 연구에서 AI 개념의 지도 필요성이 제시되고 있다. 초등학생에게 어렵고 생소한 AI 개념을 교육하기 위해 학습자의 발달 특성을 고려한 교수학습 전략이 필요하다. 선행조직자는 개념 지도 시 학습자의 인지적 부하를 줄일 수 있는 효과적인 교수학습 전략 중 하나로 이미 초등학생을 위한 인공지능 교재에 널리 사용되고 있다. 그러나 교재 분석 결과 선행조직자는 학생별 경험과 양육환경의 차이로 인해 선행조직자로서 기능하지 못할 가능성이 있다. 이를 해결하기 위해 본 연구는 초등학교에 널리 활용될 수 있는 선행조직자를 초등 교육과정에서 추출하여 AI 교육 프로그램을 개발하였다. 본 프로그램은 초등학교 5~6학년 AI 교육 내용 기준에서 AI 개념 요소를 추출하여 초등학교 1~4학년 교과 교육과정에서 선행조직자를 선정하였고 4차시의 교육 프로그램을 개발하였다. 본 연구를 통해 개발된 프로그램이 초등학생의 효과적인 AI 개념을 학습과 AI 리터러시 향상에 도움이 될 것으로 기대된다.

  • This study was conducted to understand the relationship between elementary students' beliefs supporting aggression, aggression and self-esteem. In addition, we aimed to provide basic data for controlling the aggression of children and developing effective coping strategies. This study population consisted of 184 elementary school students. Data were analyzed using SPSS 24.0 program. As a result, the aggression of elementary school students showed a significant positive correlation with beliefs supporting aggression(r=.39, p<.001) and a significant negative correlation with self-esteem(r=-.46, p<.001). In addition, Results of the hierarchical regression analysis revealed that self-esteem has the mediating effect on the relationship between beliefs supporting aggression and aggression(${\beta}=.26$, p<.001). In other words, the higher the beliefs supporting aggression, the higher the aggression, and self-esteem means to act as a mediating effect in the relationship between them. Therefore, when arranging an intervention plan to control the aggression of elementary school students, it is necessary to find strategies to control the beliefs spporting aggression and increase self-esteem.

  • For teaching division-with-remainder(DWR) problems, it is necessary to know students' strategies and errors about DWR problems. The purpose of this study is to investigate and analyze students' strategies and errors of DWR problems and to make some meaningful suggestions for teaching various methods of solving DWR problems. We constructed a test which consists of fifteen DWR problems to investigate students' solving strategies and errors. These problems include mathematical as well as syntactic structures. To apply this test, we selected 177 students from eight elementary schools in various districts of Seoul. The results were analyzed both qualitatively and quantitatively. The sixth graders' strategies can be classified as follows : Single strategies, Multi strategies and Assistant strategies. They used Division(D) strategy, Multiplication(M) strategy, and Additive Approach(A) strategy as sub-strategies. We noticed that frequently used strategies do not coincide with strategies for their success. While students in middle group used Assistant strategies frequently, students in higher group used Single strategies frequently. The sixth graders' errors can be classified as follows : Formula error(F error), Calculation error(C error), Calculation Product error(P error) and Interpretation error(I error). In this study, there were 4 elements for syntaxes in problems : large number, location of divisor and dividend, divisor size, vocabularies. When students in lower group were solving the problems, F errors appeared most frequently. However, in case of higher group, I errors appeared most frequently. Based on these results, we made some didactical suggestions.

  • This study conducted an analysis of strategies that the 3rd to 6th grade elementary students used when they were solving problems of comparing the size of the fractions with like and unlike denominators, and unit fractions. Although there were slight differences in the students' use of strategies according to the problem types, students were found to use the 'part-whole strategy', 'transforming strategy', and 'between fractions strategy' frequently. But 'pieces strategy', 'unit fraction strategy', 'within fraction strategy', and 'equivalent fraction strategy' were not used frequently. In regard to the strategy use that is appropriate to the problem condition, it was found that students needed to use the 'unit fraction strategy', and the 'within fraction strategy', whereas there were many errors in their use of the 'between fractions strategy'. Based on the results, the study attempted to provide pedagogical implications in teaching and learning for comparing the size of the fractions.

  • Given the importance of developing algebraic thinking from early grades, this study investigated an overall performance and main characteristics of algebraic thinking from a total of 197 third grade students. The national elementary mathematics curriculum in Korea does not emphasize directly essential elements of algebraic thinking but indicates indirectly some of them. This study compared our students' performance related to algebraic thinking with results of Blanton et al. (2015) which reported considerable progress of algebraic thinking by emphasizing it through a regular curriculum. The results of this study showed that Korean students solved many items correctly as compatible to Blanton et al. (2015). However, our students tended to use 'computational' strategies rather than 'structural' ones in the process of solving items related to equation. When it comes to making algebraic expressions, they tended to assign a particular value to the unknown quantity followed by the equal sign. This paper is expected to explore the algebraic thinking by elementary school students and to provide implications of how to promote students' algebraic thinking.

  • For teaching division more effectively, it is necessary to know students' informal knowledge before they learned formal knowledge about division. The purpose of this study is to research students' informal knowledge of division and to analyze meaningful suggestions to link formal knowledge of division in elementary school mathematics. According to this purpose, two research questions were set up as follows: (1) What is the students' informal knowledge before they learned formal knowledge about division in elementary school mathematics? (2) What is the difference of thinking strategies between students who have learned formal knowledge and students who have not learned formal knowledge? The conclusions are as follows: First, informal knowledge of division of natural numbers used by grade 1 and 2 varies from using concrete materials to formal operations. Second, students learning formal knowledge do not use so various strategies because of limited problem solving methods by formal knowledge. Third, acquisition of algorithm is not a prior condition for solving problems. Fourth, it is necessary that formal knowledge is connected to informal knowledge when teaching mathematics. Fifth, it is necessary to teach not only algorithms but also various strategies in the area of number and operation.

  • The purpose of this study is to investigate and analyze informal knowledge of students who do not learn the conception of proportion and to identify how the informal knowledge can be used for teaching the conception of proportion in order to present an effective method of teaching the conception. For doing this, proportion was classified into direct and inverse proportion, and 'What are the informal knowledge of students?' were researched. The subjects of this study were 117 sixth-graders who did not have prior learning on direct and inverse proportion. A total eleven problems including seven for direct proportion and four for inverse proportion, all of them related to daily life. The result are as follows; Even though students didn't learn about proportion, they solve the problems of proportion using informal knowledge such as multiplicative reasoning, proportion reasoning, single-unit strategy etc. This result implies mathematics education emphasizes student's informal knowledge for improving their mathematical ability.
