통계학의 방법론과 이론을 교수 및 연구해온지도 벌써 오랜세월이 지났지만, 한국통계학이 이론적(수리적)인 연구가 정착되지 못한 이유는 여러가지가 있겠지만, 발표자가 지적하였듯이 수리통계 학자들의 궁핍 등의 이유를 들 수 있겠다. 60년대 몇몇 대학만이 통계학과를 운영해 오고 있었으나, 70년대 들어와서 전국 각대학(교)에 통계학과의 설치인가를 받아 활발히 통계학과의 기초를 닦고 있는 현시점에서 앞으로 이론 통계학 분야의 중요성과 필요성을 발표자가 피력함으로써 이론 통계학의 중요성을 재인식시키는데 큰 도움을 줄 것이다. 통계적 이론의 바탕이 발전되어야, 이를 기반을 둔 통계적 방법 및 응용 또한 발전이 따르기 마련이기 때문이다. 추상적인 이론이라 하여, 그것을 우리는 배격할 필요는 없다. 아무리 추상적인 이론이라 할지라도 그 바탕은 간단한 문제에서 출발하고, 그 추상적인 결과 역시 여러 분야에 응용되고 있지 않는가\ulcorner 예를 들면, 수학에 있어서 위상수학은 추상적인 분야라는 사실은 너무나 잘 알고 있다. 이것 또한 수직선을 기초로 두고 생각을 했고, 그 결과 추상적 이론이 수없이 전개되어 오고 있다. 이 추상적인 이론이라 할지라도 물리학, 공학 및 경제학 등에 응용되고 있음은 어느 누구도 부인할 수 없을 것이다. 그러므로 통계학에서 이론 통계분야의 중요성과 필요성을 지적한 점은 그 의의가 크다 하겠다. 이 중요성과 필요성을 재인식함으로써 우리나라의 이론 통계학분야의 사고를 더욱 발전시켜 기초과학으로써의 기반을 튼튼하게 해야할 것이다.

This is to understand the neurological dynamic cognitive processes of math learning based on the abstract mappings( level A2), abstract systems(level A3), and single principles(level A4), which are principles of Fischer's cognitive development theory. Math learning requires flexibility to adapt existing brain function in selecting new neurophysiological activities to learn desired knowledge. This study suggests a general statistical framework for the identification of neurological patterns in different abstract learning change with optimal support. We expected that functional brain networks derived from a simple math learning would change dynamically during the supportive learning associated with different abstract levels. Task based patterns of the brain structure and function on representations of underlying connectivity suggests the possible prediction for the success of the supportive learning.

In computer education area, abstract thinking has played a positive role in programming ability, and language experience has also affected the ability. However, most of the studies were empirical. The practical research about the relation analysis between abstract thinking and programming ability has rarely been performed. Among various types of programming abilities such as coding, debugging, and reading, this paper focused on program understanding. We analyzed the affection relation on program understanding and the interaction effect between abstract thinking level and language familiarity. We surveyed 376 high school students on their abstract thinking levels, language familiarity, academic achievement, and the program understanding abilities of C and Scratch. From the research, we knew that the abstract thinking level played an important role in understanding the iterative program for the male students. In addition, if the students had the experience on other programming languages before entering high schools, then there was an interaction effect between abstract thinking level and program language familiarity.

It is the aim of this paper to suggest the method constructing abstract schema in similar mathematical problem solving processes. We analyzed closely the existing studies about the similar problem solving. We suggested the process designing a method for helping students construct an abstract schema. We designed the teaching method constructing abstract schema by appling this process to a group of similar problems chosen by researchers. We applied the designed method to a student. And we could check the possibility and practice of designed teaching method by observing the student's reaction closely.

In real educational field, there are cases that concrete problematic situations are introduced after abstract concepts are taught on the contrary to process that abstract from concrete contexts. In other words, there are cases that abstract knowledge has to be concreted. Freudenthal expresses this situation to antidogmatical inversion and indicates negative opinion. However, it is open to doubt that every class situation can proceed to abstract that begins from concrete situations or concrete materials. This study has done a comparative analysis in difference of mathematical thinking between a process that builds abstract context after being abstracted from concrete materials and that concretes abstract concepts to concrete situations and attempts to examine educational implication. For this, this study analyzed the mathematical thinking in the abstract process of concrete materials by manipulating AiC analysis tools. Based on the AiC analysis tools, this study analyzed mathematical thinking in the concrete process of abstract concept by using the way this researcher came up with. This study results that these two processes have opposite learning flow each other and significant mathematical thinking can be induced from concrete process of abstract knowledge as well as abstraction of concrete materials.

The advancement of computer technology has blurred the border in image expression between live-action films and 3D animation to an indistinguishable extent. Despite the ever-evolving image expression, it has been found that animation properly incorporating abstractive expression receives more positive responses from the audience than the animation closely akin to live-action films. This indicates that animation-specific abstractive expression can exert more significant effects than that of live-action expression as proved in Dr. Mori Masahiro's 'Uncanny Valley.' Also, such effects apply only to characters, whilst the technology capable of live-action expression is acknowledged only for the background of 3D animation. Without doubt, animation has its own infinite world of expression, and thus more effective methods for its expression can no longer be considered a matter of technology. The present study analyzes the abstractive expression of 3D animation in terms of characters and backgrounds and explores a more effective method to apply the current technology of image expression to 3D animation with a view to proposing a direction for more appropriate application of 3D animation technology to future animation.

Since creativity has been emphasized and creative problem solving has also been a big topic recently, various kinds of research works have proceeded. Among them, this paper focuses on abstract thinking and growth mindset, which affect on problem solving. Also, this paper analyzes what kinds of relationships time perspectives and smart-phone addiction have with the two factors and how they influence on them. In order to do so, we survey on 441 primary, middle, high school, and college students. Our analysis results cover the relationships among the two factors, smart-phone addiction level, present-hedonic perspective, and future time perspective. In addition, we analyze the relationship among the factors with a structural equation model. By doing these, we propose educational alternatives in terms of time and plan to improve our adolescent's abstract thinking level, which helps their problem solving skills and their academic achievement.

As a 21C core skill, computational thinking has been focused recently, and computer programming education is popular in primary and secondary schools. This paper aims to analyze the computer programming learning results based on gender difference and verify the reasons causing the difference. In this research, we focused on students' abstract thinking level as a variable and used C programming language and the RUR-PLE. Also, in this research, we focused on the concept of abstraction, one of the main component of computational thinking. And then, we analyze 587 high school students' abstract thinking level and survey them in order to find a new method for enhancing programming skill. In addition, we analyzed the causes for the difference in how the abstract thinking level applies when the students understand various structures of computer programs. From the results, we can propose a computer programming education method that enhances students' merits and compensates their drawbacks in the near future.

By analyzing abstract book cover design, this study aims to examine the applicability of the semiotic methodology of Roland Barthes and to conduct a preference survey of how people would accept it. The selected books for the study are and published in Openbooks publishing company to mark the 30^th anniversary of the opening. The research results are as follows. First, it was confirmed that Roland Barthes' semiotic approach is a suitable tool for identifying the symbolic phenomena of visual elements that constitute abstract book cover design. Second, people were well informed of what the abstract form of design conveys, but they showed personal differences in preference, making it difficult to achieve clear results. This study, together with the importance of the internal meaning that appears in the book cover design, gives graphic designers an indication that interaction between the communicator and the acceptor should be sought.
