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.

In this paper, we verified the effect and appropriateness of the scheme to cure the math. disliking disposition which is the cause of underachievement in learning. We choose 3 middle schools as the subject of experiment for this research. Each experiment class consists of 27∼30 students(underachievers) whose final test results of 1st school year in the middle school are 30∼60 points. In this case, we also select some middle level students whose test results are more than 60 points for the normal experimental condition. For this research, we developed the suitable test materials to cure the mathematics disliking disposition of underachievers. We applied those test materials to the experiment schools during 2.5 months and we analysed the variation of disliking disposition, the variation of math. dislike students' number and the cure rate of the math. disliking disposition. From the results of this experimental study, we find that the factors of teacher and math recognition environment have only the significant difference of math. disliking disposition between experiment class and comparison class under the 5% significance level in one middle school. We understand that this results caused by teachers' careful advice and guidance in that middle school. We also find that the number of student who dislike mathematics decreased in two middle schools. Furthermore 50% of math. disliking dispositions are cured for 9 disliking factors in the lower grade group(the group of underachievers) and as a whole, we can see that 50% of cure rate for the 7 factors of math. disliking in two middle schools. So we can understand that the experiment of our research was performed successfully in two middle schools. In this research, we find out that the scheme to cure the disliking dispositions for the factors of math. disliking depends on the factors of teacher who take charge of cure. So teachers must take interest in and must have careful concern to students and their math. disliking.

인간의 내면에서 일어나는 여러 가지 변화들을 인간의 지식으로써 표현하는 것이 여러 언어적인 표현이다. 그러나 인간이 무엇을 알고 있는가에 대하여, 표현하기란 그 누구도 결코 불가능한 것일 수도 있고 그렇지 않을 수도 있다. 그리고 인간의 지식을 표현하는 언어로서 자문자답한다고 하더라도 그 결과는 역시 알 수 없는 미궁으로 빠지게 됨을 그 누구나 공감하게 된다. 그렇다고 한다면 수를 보는 시각과 인류 문명에 대한 시각, 그리고 인간사고에 대해서도 이제 새롭게 볼 수 있는 시각이 요구되고 있다. 새로운 시각으로 수의 성질을 크게 존재 ${\cdot}$ 법칙 ${\cdot}$ 구조와 질서 ${\cdot}$ 힘 ${\cdot}$ 양과 질 ${\cdot}$ 통일로 분류하여 알아보았다. 다른 한편으로는 개인의 수 개념 형성에 초점을 둔 Piaget이론을 소개하고 있다 그리고 경험주의 선구자인 Dewey의 수 개념을 소개하고 있다. 역사와 수, 인체와 수에서는 동이와 수리사상이 인체와 관련된다는 사실은 동 ${\cdot}$ 서양을 막론하고 확인되고 있다. 인체와 수에 대한 것을 동양인 중국 문화권에서 일(一)부터 십(十)까지의 기호를 인체와 연결시켜 소개하였다. 수의 본질을 알고 이해하는 것이 곧 자연현상의 이해이며 그 자연의 일부인 인간을 이해하고 동시에 역사를 이해하는 기본이라 아니할 수 없을 것이다. 따라서 수를 보는 시각이 달라지지 않으면 수학을 기피하는 현상은 계속될 것이다.

There are various efforts to alleviate problems about the learning disabilities each year, however, the number of the learning disabilities has been increasing. Therefore, we need to consider and develop practical methods to help them. In this aspect, we review and examine previous research regarding the learning disabilities which are known to be general and comprehensive. Then we suggest math clinic as one of the methods to alleviate the problem. There are purposes of the math clinic. The first is to make a comprehensive diagnosis for basic (emotional, environmental, psychological) reasons as well as the learning anxiety; not only the lower achievement in learning. The second is to provide them suitable corrective programs which would help them to gain a better understanding about mathematics and a positive learning attitude. The third is to provide them applicabilities in their learning and potentialities so that we have given them foundation in mathematics. In this article, we operate math clinic for the learning disabilities, and then make an analysis of the student's error occurred in learning, and finally we suggest a demonstrative operating program of math clinic for learning disabilities.

In this study, the case of error became the object of learning, and the investigator applied these cases to an actual class and established three study problems in order to achieve the purpose of this study. The results of analysis of students' errors in figure based on before achievement test are shown as follows: First, the most errors occurred in the figure was the ones from deficient mastery of prerequisite concepts and definitions. Specially, the errors from deficient mastery of prerequisite concepts and definitions have the majority. it is very high ratio even if it considers an influence of an evaluation question item. so, I think it is necessary to teach concept related figure above all. Second, as the results of application 'finding errors' to a class, there is a meaningful difference in the mathematical achievement and reasoning ability within significance level 5%. This means 'finding errors' is one of the teaching method that it develops the mathematical achievement and reasoning ability.

Currently Science and technology are changing so fast these days, educating competent and creative person, majoring in natural sciences, including mathematics., becoming more and more important. But, in Korea, there are many problems in high school and university education program, so performance level in mathematics is decreasing and avoiding mathematics and natural sciences is increasing. Naturally the numbers of science oritented students in high school are decreasing and ability in mathematics, in particular calculus, is decreasing. Hence, the above situation leads to a reduction of scientific manpower. In this point of a view, we analyse the situation of the downturn of the ability of the science, especially calculus, among engineering majored freshmen. We also study many data reported by Ministry of Education and Science, Korea and scholar societies. From this study we conclude that the essential rerasons for the above situations are curriculum and the system of the entrance examination of the university, and we give suggestions for solutions of such a situation.

The convergent education such as STEAM education has been implemented in the gifted education institutions in order to resolve the crisis of science and engineering fields caused by the science and engineering avoidance of excellent talents. The purpose of this study was to investigate awareness about science, mathematics and technology/ engineering fields of science gifted students. The subjects were 86 middle school science gifted students at the Science Institute for Gifted Students of a university located in metropolitan city in Korea. The data were collected from the survey that consists of 97 questions in 3 categories. The results were follows: First, the gifted students were aware that science was more interesting than mathematics or technology/engineering. Second, science rated highest in career choice. Third, they were aware that the scientists were more interesting, more imagination, less accuracy and less considering than the mathematicians and the engineers. In addition they responded that the mathematicians were smarter than the scientists and the engineers, and the engineers were more diligent than the scientists and the mathematicians. Finally, the result of the correlational analysis indicated that there were strong correlations between science and mathematics, and between science and technology/engineering. It was recommended that the consolidation of the convergent gifted education, the necessity of systemic career education, and the study of correlation between mathematics and technology/engineering.
