본 논문은 입시교육에 치중함으로써 흥미나 자신감을 잃고 학습 결손이 누적되어 학습을 포기하는 학생들이 속출하는 인문계 고등학교에서 수학에 대한 인식 및 이해실태를 정확히 진단한 후, 도출된 문제점을 해결할 수 있는 방안으로 활동중심의 교수-학습 방법을 구안ㆍ적용하였다. 설문조사와 참여관찰평가, 인터뷰 자료의 분석 결과, 수학수업의 긍정적 변화를 알 수 있었다.

In this paper, we investigate the comparative effectiveness of two kinds of instructional methods in transfer of mathematics learning: one based on the situated cognition, i.e. situated learning (SL) and the other based on traditional learning (TL). Both classes (of grade 2) studied addition and subtraction of 3-digit numbers. After that, they completed two written tests (Written Test 1 included computation problems, Written Test 2 included computation problems and story problems) and a real situation test. As a result, no significant differences were found between the two groups' performance on computation skill in Written Tests 1 and 2. But the SL group performed significantly better on the performance of story problem and real situation test than TL group. This result indicated that the SL made improvement in transfer of mathematics learning. As a result of interviews with 12 children of the SL group were able to use contextual resources in solving real situation as well as story problems.

Computer architecture serves as a link between application requirements and underlying technology capabilities such as technical, mathematical, medical, and business applications' computational and storage demands are constantly increasing. Machine learning these days grown and used in many fields and it performed better than traditional computing in applications that need to be implemented by using mathematical algorithms. A mathematical algorithm requires more extensive and quicker calculations, higher computer architecture specification, and takes longer execution time. Therefore, there is a need to improve the use of computer hardware such as CPU, memory, etc. optimization has a main role to reduce the execution time and improve the utilization of computer recourses. And for the importance of execution time in implementing machine learning supervised module linear regression, in this paper we focus on optimizing machine learning algorithms, for this purpose we write a (Diabetes prediction program) and applying on it a Practical Swarm Optimization (PSO) to reduce the execution time and improve the utilization of computer resources. Finally, a massive improvement in execution time were observed.

In this article, we develop a 'dynamic' approach to manufacturing improvement, based on perspectives of manufacturing learning and decision theory. First, we present an alternative definition of production system consistent with a decision-theoretic perspective: the system consists of structural, infra-structural, and decision making constructs. A primary proposition is that learning capability possessed by a manufacturing system be prerequisite for the system to improve its manufacturing performance through optimal controlling of the three constructs. To support the proposition, we elaborate on a mathematical representation of "learning" as defined in an applied setting. We show how the learning capability acts as an integrating force ameliorating the trade-off between two key manufacturing capabilities, i.e., process controllability and process flexibility.exibility.

실행연구는 연구자가 문제의식을 가지고 실제를 개선하고 자신의 전문적 지식을 향상시켜 나가는 연구이다. 본 연구는 학생들이 학교와 가정에서 수학을 많이 접함에도 불구하고 수학적 문제해결력이 낮고 실생활에 적용시키는 수학적 이해력이 부족하다는 문제점을 인식한 교사가 학생들의 수학적 이해력을 높이고 교사 자신의 수학 교수법을 계발하려 데서 출발하였다. 본 연구를 실행한 교사는 수학적 지식을 적용할 수 있는 문제 상황을 학생들 스스로가 잦아보게 하여 수학을 실생활에 적용할 줄 알고 수학과 친숙해지도록 하는 수학적 이해력을 신장시키기 위한 방안으로 상황중심의 문제해결 모형을 고안하였다. 본문에서는 교사가 연구자가 되어 학생들의 이해를 촉진시키기 위하여 개발한 상황중심의 수업 모형을 설명하고, 이를 적용하는 과정과 수업의 반성을 통해서 얻은 연구자의 성찰적 지식을 정리하였다.

문제 만들기 단계와 다양한 문제 만들기 학습 자료를 사용한 문제 만들기 교수-학습 모형을 고안하여 4-가 단계 수학 수업에 적용함으로써, 이 교수-학습 모형이 학생들의 수학적 문제 해결력 및 수학적 태도에 긍정적인 효과를 주는지 알아보았다. 이를 위해 실험반은 문제 만들기 교수-학습 활동을, 비교반에는 일반적인 교수-학습 활동을 실시하는 실험 연구를 실시하였으며, 그 결과 첫째, 문제 만들기를 적용하여 교수-학습 활동을 실시한 실험반이 비교반보다 문제 해결력 향상에 있어서 유의미한 효과가 있었고, 둘째, 문제 만들기를 적용하여 교수-학습 활동을 실시한 실험반의 수학 학습 태도에 긍정적인 변화가 있었음을 알 수 있었다.

본 연구에서는 중위권 공과대학 신입생들의 자기주도학습준비도와 수학적성향 사이의 관계를 알아보기 위하여, D대학교 공과대학 2011학년도 신입생들을 대상으로 자기주도학습준비도 검사와 수학적성향 검사 및 수학에 대한 인식 설문을 실시하였고, 자기주도학습준비도를 수학적성향의 요인 및 수학에 대한 인식 정도에 따라 분석하였다. 연구 결과, D대학교 공과대학 2011학년도 신입생들은 대체로 자기주도학습준비도가 미약하며, 자기주도학습준비도는 수학적성향 및 수학에 대한 인식과 밀접한 관계가 있는 것으로 나타났다. 본 연구 결과를 바탕으로 효율적인 대학수학 교육을 위해서는 대학수학 교수 학습에서 자기주도학습준비도의 향상에 초점을 두어야 함을 제언하였다.

In this study, we proposed a learning-centered DIY mathematics instruction for students to actively design instructions and developed important competencies. The research problems of this study were as follows. First, how did learning-centered DIY mathematics instruction affect math academic achievement? Second, how did learning-centered DIY mathematics instruction affect the affective domain? Third, what was the reaction of students to the implementation of the learning-centered DIY mathematics instruction? For this purpose, this study was conducted with 58 students in 2 classes of 2nd grade of 00 High School located in 00 Metropolitan City. As a result of the study, first, it could be seen that the study group that taught the learning-centered DIY mathematics instruction was very helpful in the change of mathematics academic achievement compared to the comparative group who taught the explanatory instruction based on traditional textbooks. Second, the research group showed a significant improvement in the affective domain compared to the comparison group. Third, the responses of the students in the research group through the learning-centered DIY mathematics instruction improved in a positive direction, and there were some negative responses.

Compared with other subjects, mathematics has great differences in achievement. In hope of solving this problems, most schools the level-movement learning. Although they say it may have some effect because of its homogeneous group, the level groups still have differences in achievement in their students abilities. So, this study aims to present an appropriate tasks for the advanced intermediate and beginner groups and to help self-directed learning by selecting an appropriate tasks for the students' own level. To achieve thiese goals, a great deal of level tasks were developed and given to the students. After lettins them an select appropriate tasks for their own level and perform self-directed teaming, the tasks were measured carefully for their interest attitude and achievement in learning. Consequently, we tried a new method to improve uniformity and to turn teacher-centered learning into student-centered teaming. The following is the conclusion to this study. First self-directed teaming based on the selection of level tasks has meaningful effects on learning achievement in mathematics, especially for the beginner group. Second though the above method did not improve an interest for mathematics, but was very effective in the improvement of learning attitudes.
