What matters in the society of knowledge and information is not that they just know certain facts, but that when faced with new situations, they should be able to develop novel ideas, apply them and do the problems or the tasks confronting them. This cannot be achieved through learning of mere knowledge. Computer programming lessons have shown positive effects on general thinking ability, metacognitive aspects, and logical thinking. The ACM has suggested that 8th grade students at the first level (second year students of middle school) be educated in programming languages such as LOGO to raise their ability to think logically. Previous studies have confirmed educational programming languages such as LOGO and BASIC, which are currently used, are helpful in improving the ability to think logically and to solve problems. However these languages lack connectivity with later learning. Little research has been done on 'Dolittle', an educational programming language, newly developed, using object-oriented notions. Few studies have been made of the effects of 'Dolittle' on the ability to think logically. The following results were obtained. The research didn't lead to a statistically significant improvement of the students' cognitive development level. However, proportional logic and combinational logic, among the six subcategories of logic, improved through the introduction of 'Dolittle' programming lessons. This leads to the conclusion that in the processing of solving the problems given, the students learned by themselves and improved their ability to think logically.

The purpose of this study was to investigate cognitive development and logical thinking formation levels of elementary gifted students and to compare with those of elementary regular students. For this purpose, 79 gifted elementary school students and 114 regular elementary school students in Kyunggi Province were participated, and GALT(Group Assessment of Logical Test) was administered to them. The results obtained in this study were as follows. First, the logical thinking scores of elementary gifted students were significantly higher than general students'(p<.05). Comparing the distribution of cognitive development level, elementary gifted students showed higher ratio in formal operation and lower ratio in concrete operation compared to the general students. It was interpreted that the cognitive development of gifted students preceded general students'. Second, analyzing according to the grade of elementary gifted students, logical thinking scores were significantly different between 5th graders and 6th graders(p<.05). Compared to 5th graders, logical thinking and formal operation ratio of 6th gifted graders showed significantly higher. The scores of four logical thinking areas except for conservational logic and correlational logic of 6th gifted graders showed significantly higher than 5th gifted graders'. Both 5th and 6th graders showed the highest formation ratio in combinational logic, and the lowest ratio in correlational logic. Third, logical thinking scores of gifted students according to gender did not show a significant difference(p>.05). The gifted boys reached formal operation more than gifted girls, but stayed more in the concrete operation. There was gender difference in correlational logic. The gifted girls showed significantly higher than gifted boys in correlational logic(p<.05).

This paper deals with set-theoretic Kripke-style semantics for FR, a fuzzy version of R of Relevance. For this, first, we introduce the system FR and its corresponding Kripke-style semantics. Next, we provide set-theoretic completeness results for it.

‘수학을 한다는 것은 수학자가 하는 것처럼 하는 것이다.’ 이 말은 여러 번의 시도와 실패를 반복해 가면서 ‘왜 이렇게 될까?’ 라는 의문을 가지고 여러 가지 창의적인 수학적 사고를 먼저 해보고 문제를 대하는 것을 뜻한다. 생활 속의 수학 문제는 바로 이 점에서 시사하는 바가 크다. 이런 수학 문제를 풀 때 학생들은 수동적이 아닌 능동적인 논리적 사고를 한다. 본 연구에서는 대학 입시제도로 인해 지금까지의 수학을 암기위주로 수동적으로만 학습하였던 수학 부진학생들에게 생활과 연관된 수학문제들을 제시함으로써 수학 우수 학생과 비슷한 능동적 구성활동을 유발할 수 있었으며 수학 부진 학생들과 우수 학생들의 지금까지 배운 수학 학습의 전이에 어떤 요인이 영향을 주었는지를 조사하였다.

We studied the perceived creative ability, convergent thinking and creative leadership related to converged capabilities among students who participated in the capstone design and graduation works and those who did not participate. In creative ability, students who participated capstone design and graduation works need more curriculum and non-curriculum activities for the idea generation through the understanding of various majors, but overall, they achieved higher positive results than the nonparticipating students. For creative leadership and convergent thinking, students with capstone design and graduation works showed a more positive capabilities, while students with nonparticipating students showed a slightly lack of creative thinking of higher order thinking, the logical analysis of complex phenomena, and overall understanding.

과학을 어려워하는 어린이들에게 테크놀로지 교육은 학습자가 직접 로봇을 제작, 프로그래밍, 실행해 봄으로써 게임을 즐기듯 재미있게 참여하면서 창의적인 사고 능력과 문제 해결능력을 길러주는데 효과적이다. 본 논문은 현재 실시되고 있는 외국의 로봇교육과정을 살펴보고, 우리나라 초등학교 수준에 맞는 테크놀로지 교육과정을 수준별로 구성하였다. 이를 통해 학습자로 하여금 역동적인 상호작용을 이끌어 냄으로써, 논리적이고 비판적인 사고 능력 함양은 물론, 창의적이고 자기 주도적 문제해결능력 신장을 도모하고자 하였다.

본 논문에서는 최근 교육현장에서 늘어나는 코딩교육의 중요성을 알고 유아교육에서 코딩교육이 제대로 이루어 질수 있도록 환경적 및 내용적 측면을 제안하는 것이다. 제 4차 산업혁명으로 인하여 모든 사람들이 융합적 사고를 갖고 문제해결능력을 갖추어야 하는 시대를 맞게 되었다. 따라서, 유아기때부터 컴퓨팅 사고력을 위한 교육이 이루어지며, 이를 통해 논리적 사고와 문제 해결능력을 향상시키고, 디지털 미래세대의 주역이 될 수 있도록 하고자 한다. 그러나 아직까지 유아교육분야에서 코딩관련된 제품들은 많이 나오고 있으나 이에 대한 평가나 학문적 검증은 거의 이루어지지 않고 있으므로 이에 대한 방법적 측면을 제안하고자 한다.

기존의 이진논리는 애매모호한 인간의 지식을 표현하는데 많은 여러움이 있었다. 컴퓨터의 사고를 보다 인간에 가깝게 하기 위해 0과 1의 이진논리가 아닌, 0과1 사이의 실수로 애매모호함을 표현하는 Zadeh의 퍼지집합이론이 제안되었다. 이를 기초로 하여, 실제로 여러 종류의 퍼지 연산들을 수행하는 퍼지프로세서들이 개발되었으며, 퍼지 컴퓨터를 실현시키기 위한 연구가 활발히 진행되고 있다. 본고에서는 퍼지논리에 기초하여 퍼지정보처리(Fuzzy Information Processing)을 수행하는 대표적인 하드웨어 시스템인 퍼지 컴퓨터와 퍼지 컨트롤러 (fuzzy controller)에 대해 알아보고 다단계 퍼지 추론을 수행하는 퍼지 메모리 모듈(fuzzy memory module)의 기본인 퍼지 플립플롭에 대해 알아보고자 한다.

The purpose of this study was to investigate characteristics of mathematically gifted high school students' thinking in design activities using GrafEq. Eight mathematically gifted high school students, who already learned graphs of functions and inequalities necessary for design activities, were selected to work in pairs in our experiment. Results indicate that logical thinking and mathematical abstraction, intuitive and structural insights, flexible thinking, divergent thinking and originality, generalization and inductive reasoning emerged in the design activities. Nonetheless, fine-grained analysis of their mathematical activities also implies that teachers for gifted students need to emphasize both geometric and algebraic aspects of mathematical subjects, especially, algebraic expressions, and the tasks for the students are to be rich enough to provide a variety of ways to simplify the expressions.

In this work, we develop an instructional method in which students create 3D animations based on problem-solving techniques and computational thinking. The educational, easy-to-learn programming environment/language called "Alice 2.3", which supports story-telling, is used for the delivery of the instructional method. Unlike typical 3D animation instructional methods using command-based demonstrations and/or 3D animation tools, learners engage in a group project in which they develop a story and solve problems by creativity, computational thinking and reasoning skills. Then they develop animations based on the story by programming with Alice. The analysis based on the collected data showed that learners had to put much effort while working on the project, but their critical-thinking skills were improved. It also showed they were more involved and their interests were heightened in developing animation through programming.
