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).

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

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.

필자들은 제37회 교육자료전시회(1997)와 제38회 교육자료전시회(1998)에 작품을 출품하였다. 이들 교육자료전시회에 참가하게 된 동기는 다음과 같다. 입문기 아동의 수학교육은 학습내용에 대한 흥미를 가지도록 해야 하며 구체적인 조작활동을 통하여 수량에 대한 기초적인 개념과 원리, 그리고 법칙을 바르게 이해시켜 논리적 사고력을 기르도록 해야 한다. 그러나 대부분의 아동들을 목표수준에서 보면 만족스럽지 못하고, 시간이 지날수록 학습결손아가 늘고 있는 현실이다. 특히 오름길 학습지를 해결할 때는 우수한 아동에게도 조작활동을 시켜보면 뜻밖에 조작 활동을 제대로 못하고 당황하는 경우를 흔히 볼 수 있다. 이것은 개념 형성과 개인간의 차에 관심을 둔 지도가 이루어지지 않은 상태에서, 자기능력과 수준에 맞는 학습을 하지 못하고 다음 단계로 넘어가기 때문이라 판단하였다. 이에 필자들은 교과서에 예시한 활동이나 그림 자료들을 실제로 관찰하고 조작해 볼 수 있도록 구체적인 자료로 대체하여, 수학에서 요구하는 학습지도 원리에 적합하도록 하였다. 또 교실 수업에서 야기되는 개인차에 대한 학습지도상의 문제점을 해결하는 한편, 급우간 인간관계에 바탕을 둔 소그룹 협동 학습을 위한 자료로 수와 가감산의 원리를 쉽게 체득 시킬 수 있도록 하였다.

체계적인 교육과정의 부재로 인한 학교 현장의 파행적 운영과 컴퓨터를 타 교과의 효율적 학습을 위한 도구로만 인식하는 활용 위주의 컴퓨터 교육은 정보 소양을 등한시 하는 결과를 낳았다. 미국, 프랑스, 영국, 일본 등 교육 선진국은 활용을 위한 컴퓨터교육 뿐 아니라 체계적인 정보 소양 교육을 실시하고 있고 현재 많은 현장의 초등 교사들도 정보 소양 교육의 체계적인 교육 과정의 필요성을 느끼고 있으며 현장에서 초등학생들에게 쉽게 적용할 수 있는 컴퓨터 교육 내용을 원하고 있다. 정보화 사회에서 초등학생에 맞는 교육 내용의 구성은 컴퓨터의 바른 인식과 그 과정에서 얻어질 논리적인 사고력의 자연적 학습이 가능 할 것이며 정보화 시대의 요구에 부응하는 인간 형성에 기여 할 것이다. 그러므로 정보화 시대를 살아갈 우리 아동들에게 초등 컴퓨터 교육의 올바른 방향은 정보 소양 중심의 컴퓨터 교육 과정으로 체계적인 교육과정과 교과로서의 독립적인 운영과 초등 수준에 맞는 교육 내용의 구성이다.

This is one of the basic research for inspecting the possibility of the development of logical thinking capability to make possible formal thinking. The 5th grade students (n=306) in the elementary school were participated in this study. Performing the 6 variable-controlling activities in the 'Thinking Science' program for one semester, the SRT II test and the Variable-Controlling test were operated to examine the effects on the development of the variable-controlling ability by treatments, gender, and cognitive levels. Performing of the variable-controlling activities was highly successive on the development of students' variable-controlling ability. Although learning effect on the ability of identifying causal variable was moderate, the abilities of controlling experimental condition, measurement of variable, and identifying result variable were significantly developed. There was statistically significant difference by gender. Girls showed better performance all the time in both groups. Boys in the experimental group were getting better gradually, so the difference by gender was somewhat decreased. Examining the variable-controlling ability by cognitive levels, students in the experimental group show significant increase in all levels, especially the students in early, mid, and mature concrete level show substantial learning effects. The results of this study implied that the variable-controlling activities in the 'Thinking Science' could be effective for learning of variable-controlling and eventually for the development of logical thinking capability to make possible formal thinking.

The purpose of this study is to develope the more effective chemistry teaching strategy through analyzing the demanded cognitive levels of contents in high school chemistry I textbooks and the cognitive levels of students who learn these textbooks. For this purpose, the levets of cognitive development stages of 821 second grade students of high schools in Seoul City were anaIyzed using the GALT short version test. The demanded cognitive levels of understanding the contents of chemistry I textbooks in high school were analyzed using the curriculum analysis taxonomy developed by CSMS (Concept in Secondaly Mathematics and Science) program of the Great Britain. The resuIts showed that the proportion of students in the concrete operational stage, the transition stage, and the formal operational stage was l0.7%, 43.0% and 46.3%, respectively. The demanded levels of textbook contents were mostly the early formal operational stages. The concepts demanded the level of the late formal operational stage were 'atomic and molecular weight', 'stoichiometry of chemical reaction', and 'periodic properties of elements'. The results will be helpful for teachers in knowing what concepts are difficult for students to understand and in planning strategies for teaching those concepts. To demonstrate the application of the results obtained in this study, an example of developing teaching strategy which includes the adjustment of cognitive level of contents was shown.

The purpose of this study was to analyze the controversial points in the concepts of materials in the science textbook of middle school and to provide alternatives of teaching method. For this study, units in connected textbooks were analyzed and the teaching method using ball-and-stick models was developed. The subjects were 130 second graders from a middle school in Seoul, Korea. It aimed to compare the effectiveness of using ball-and-stick models for lesson with the one of traditional lessons, in learning concepts concerning materials by cognitive levels and to investigate the difference of scientific concept formation about concepts concerning materials by their cognitive levels between experimental group and control group by using concept formation questionnaires. Before the instructions, a short-version GALT was administered. After instructions, the posttest of concepts and attitude test connected with science subject were administered, and 10 months later, the posttest of concepts was administered to analyze the long-term memory effects. According to the results, the experimental group using the ball-and-stick models had significantly higher scores at conceptual understanding and long-term memory effects than the control group and improved the attitude relevant to science subject, and also had affirmative effects in attitude for science and science work. When analyzing the results according to the cognitive level, the long-term memory effects was high in the concrete operational stage students. From the results of this study, middle school students that are more concrete operational stage and transitional stage than formal operational stage elevates interesting in studying by using ball-and-stick models and making material form concretely. It would be effective in helping the students develope the correct concepts by connecting real world as materials and the particle world as atom.
