로봇은 지식기반사회에서의 요구하는 기초 능력과 문제해결력 함양을 위한 학습을 충족시켜줄 것으로 기대된다. 또한 로봇교육은 공학적으로 여러 기술이 관련되어 있으므로 통합적인 기초 교육이 가능하게 할 것이다. 그러나 학습 내용, 학습 방법 및 학습 교재에 대한 연구가 부족하므로 외국에서 실시하고 있는 로봇교육과정을 분석하였다. 해외 사례 분석 결과 로봇을 통해 기초 능력과 문제해결력을 함양하기 위한 교육목표를 체계적으로 달성하기 위해서는 학교 교육과정으로 운영되어야 하며 로봇의 특성과 관련된 과학, 수학, 기술, 공학의 내용 요소들을 추출하며 로봇소양에 대한 내용뿐만 아니라 로봇활용에 대한 내용으로도 구성해야 하며 로봇 창작 시스템을 이용하여 단순한 로봇 조립보다는 창작 및 프로그래밍의 과정이 이루어질 때 효과적으로 학습의 성과를 거둘 수 있을 것이다.

알고리즘이란 ‘유한한 단계를 거쳐 일련의 문제를 해결하기 위한 명확하고 체계적인 방법’ 으로써 수량에 관련된 문제를 보다 신속 ${\cdot}$ 정확하게 처리하기 위하여 역사적으로 다양한 알고리즘이 존재 ${\cdot}$ 변천해 왔다. 계산기가 발명되기 전까지는 지필 알고리즘이 매우 강조되어 왔으나 계산기가 상용화되면서 지필알고리즘에 대한 효용성과 활용도가 점차 줄어들고 있으나 지필 알고리즘은 수학학습의 기초 ${\cdot}$ 기본인 동시에 뼈대로써 그 가치와 역할은 여전히 중요하다. 그러나 표준화된 지필 알고리즘에 대한 지나친 강조로 인해 학생들은 대수적 구조나 계산 원리를 바르게 이해하지 못한 채 반복 연습을 통해 익힌 표준 알고리즘을 기계적으로 적용하여 답을 구하는 경우가 많으며, 이로 인해 학생들은 수학학습에 대한 불안감과 기피현상이 보이고 있다. 또 인간의 창조적 사고활동의 최종적인 산물인 표준 알고리즘은 대안적인 알고리즘에 비해 효율성에서 앞서지만 학생들의 사고 수준에서는 그 원리를 이해하기 힘든 경우가 있을 것이다. 따라서 수학교육의 목적 중의 하나인 문제 해결력을 기르기 위해, 그리고 표준 알고리즘의 가치와 효율성을 인식시키고, 수학학습에 대한 불안감을 줄이기 위해 표준 알고리즘뿐만 아니라 대안적인 알고리즘을 병행하여 지도할 필요가 있다.

NCS (National Competency Standards) has emerged as an issue of great importance amongst Korean universities and corporations. Although previously used mostly for vocational education purposes at colleges, NCS is currently receiving an increasing amount of attention from 4-year universities as well. In the ever-evolving information economy, the basic workplace skills defined by NCS, which include soft skills such as communication skills, problem-solving skills, and interpersonal skills, have now become more important than specific technical skills. This study analyzes the correlation between the basic workplace skills of NCS with participation in Formula SAE activities, a common component of Capstone design courses across North America and Europe. Data are derived from site visits to Formula SAE competitions, competition-related documents drafted by student participants, and questionnaires administered to student participants at the Formula SAE Lincoln completion and at the Korea KSAE competition. From the study findings, we claim that the basic workplace skills of NCS are closely correlated to participation in Formula SAE activities. Through a survey designed to measure the degree to which Formula SAE activities can enhance an individual's NCS Basic Workplace Skills, we find that these activities overall improved NCS basic workplace skills averaging 4.0 points above in the Likert 5-point scale. For reference the mathematical skills, communication skills, and problem-solving skills displayed statistically significantly correlation with NCS but the remaining 7 skills did not show a statistically strong correlation with NCS comparatively.

The purpose of this study was to investigate the effects of Mathematical Activities using 4D-frame on 5-year-old children's mathematical ability and attitude towards Mathematics. For the study, E, K, and Y preschools located in S city were selected: 28 children from Y preschool as the experimental group(I: n=14, II: n=14) and 28 children from E and K preschool as the comparative group(III: n=14, IV: n=14). During the 8 weeks, the experimental group performed Mathematical Activities using 4D-frame and in the comparison group, Nuri-Curriculum's mathematical activities and mathematics-science integration programs were conducted. The analysis of covariance(ANCOVA) was conducted with the pre-test scores of the experimental group(I, II) and the comparison group(III, IV) as covariance. The results showed that there were statistically significant differences between the experimental and comparative groups. Mathematical Activities for Young Children using 4D-frame enhanced 5-year-old children's mathematical ability and attitude towards Mathematics. The results of this study provide an understanding of the efficiency of early childhood mathematical activities using the 4D-frame in early childhood education and provide basic data for the improvement of mathematical ability and attitude of young children and the applicable educational methods at the field.

Mathematical ability is important for academic achievement and technological renovations in the STEM disciplines. This study concentrated on the relationship between neural basis of mathematical cognition and its mechanisms. These cognitive functions include domain specific abilities such as numerical skills and visuospatial abilities, as well as domain general abilities which include language, long term memory, and working memory capacity. Individuals can perform higher cognitive functions such as abstract thinking and reasoning based on these basic cognitive functions. The next topic covered in this study is about individual differences in mathematical abilities. Neural efficiency theory was incorporated in this study to view mathematical talent. According to the theory, a person with mathematical talent uses his or her brain more efficiently than the effortful endeavour of the average human being. Mathematically gifted students show different brain activities when compared to average students. Interhemispheric and intrahemispheric connectivities are enhanced in those students, particularly in the right brain along fronto-parietal longitudinal fasciculus. The third topic deals with growth and development in mathematical capacity. As individuals mature, practice mathematical skills, and gain knowledge, such changes are reflected in cortical activation, which include changes in the activation level, redistribution, and reorganization in the supporting cortex. Among these, reorganization can be related to neural plasticity. Neural plasticity was observed in professional mathematicians and children with mathematical learning disabilities. Last topic is about mathematical creativity viewed from Neural Darwinism. When the brain is faced with a novel problem, it needs to collect all of the necessary concepts(knowledge) from long term memory, make multitudes of connections, and test which ones have the highest probability in helping solve the unusual problem. Having followed the above brain modifying steps, once the brain finally finds the correct response to the novel problem, the final response comes as a form of inspiration. For a novice, the first step of acquisition of knowledge structure is the most important. However, as expertise increases, the latter two stages of making connections and selection become more important.

In mathematics classes, the verbal explanation may contain diverse mathematical concepts and principles in short sentences. It may also include mathematics symbols and terms that might not be used in everyday life. Therefore, students may need particular listening ability in order to understand and participate in mathematics communication. Unlike general listening, the listening ability for mathematics classes may require student to integrate their mathematical and linguistic knowledge. The aim of this study is to reveal the subdomains of listening ability for mathematics classes in a elementary school. I categorized listening ability for mathematics classes in a elementary school from the literature. The categories of listening ability for mathematics are Interpretive Listening, Evaluative Listening, Hermeneutic Listening, Selective Listening, Pretend Listening, and Ignored Listening. In order to develop a framework for understanding listening ability for mathematics classes, I investigated a hierarchy of 412 South Korean elementary teachers' perception. Through a web-based survey, the teachers were asked to rank order their beliefs about and students' listening ability. Findings show that teachers' perceptions about listening ability for mathematics classes are divergent from current research trends. South Korean elementary teachers perceived Interpretive Listening as the most important listening.

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.
