Because all areas of mechanical engineering involves the use of mathematics, mechanical engineers need mathematical understanding and skill enhancement. To achieve the effective mathematics education for mechanical undergraduate students, it should reorganize the important subtopics of mathematics. In this paper, we explore the direction of the development of mathematics education for mechanical engineers by analyzing the teaching hours of each topics in the mathematics and by comparing the results with significance analysis of expert survey. To do so, syllabuses of mathematics courses of the selected mechanical engineering departments were analyzed and the survey responses of professionals in the Korean Society of Mechanical Engineers were also investigated. Finally, the revision of mathematics curriculum in the mechanical engineering was proposed.

This study investigates the relationship of mathematics anxiety and achievement in college mathematics for engineering major freshman students. An revised and modified 30-item version of the Mathematics Anxiety Scale(MAS) was completed by 176 university engineering students enrolled in introductory calculus courses offered by the department of mathematics. Correlational analysis indicated complex interaction patterns between mathematics anxiety and mathematics achievement, depending on the level of anxiety. The results from this study confirm the negative correlation between mathematics anxiety and mathematics achievement in college mathematics for engineering major student, and also those support the claim that the relationships between mathematics anxiety and achievement have non-linear patterns.

This study aims to investigate relationships among self-directed learning readiness [SDLR], prerequisite mathematics test score and achievement level in college mathematics. For this purpose, the adjusted SDLRS (self-directed learning readiness scale) of Guglielmino's model, the score of mathematics diagnostic assesment and first semester college mathematics score among 424 freshmen students of engineering department of D university in 2011 were used and analyzed. Research results are as follows: Firstly, freshmen of engineering department had average level of SDLR, though they showed relative low level of self-direction, passion and time control ability. Secondly, considering SDLR with the mathematics diagnostic assesment score (3 groups: high, middle, low), there were no statistically significant differences. Thirdly, concerning SDLR according to the achievement level in college mathematics, a group which acquired good achievement showed higher level of SDLR compared with middle or lowachievement group. Differences among three groups were statistically significant. Lastly, there were affirmative relationships between SDLR, mathematics diagnostic assesment score and achievement in college mathematics. Furthermore, mathematics diagnostic assesment score and achievement level in college mathematics were found to be the most closely related. Based on the results, we suggest strategies to elevate SDLR of engineering department students and improve their achievement in college mathematics.

How to teach calculus is an important issue since Calculus is the first mathematics in college curriculum which highly influences other subjects including Physics, Engineering Mathematics like differential equations, and other engineering major subjects. This study suggests that a class model of Engineering Mathematics include Calculus review test so that students can study for themselves Calculus 'outside Calculus class'. First of all, a systematic process of administrating a review test is presented. Secondly, scores of the Calculus review test is statistically analyzed to confirm that ability in Calculus is highly correlated to their achievements in Engineering mathematics. Through a survey, it is confirmed that students in Engineering Mathematics study Calculus for themselves as they think Calculus review test is helpful.

What is the "new paradigm"? It is impossible express it in one or two words, but if one had to; the closest might be the "holistic approach". The expression can be justified by the fact that the conclusions above lead to a greater intermixing of mathematics with engineering and natural sciences subjects, typically expressed in the form of examples of simplified real problems. They also lead to a greater intermixing of subjects within mathematics so that the courses should have less separation e.g. between symbolic and numerical mathematics. The conclusions also lead to the spreading the mathematics courses throughout all study years, not just the first two years. Of course, this should be done with great care in order to guarantee studies that are logically linked together. The new paradigm also means that the needs arising from industrial mathematics must be taken into account in the contents of engineering mathematics courses. Such topics are e.g. multivariate methods, statistics and use of mathematical software. What are we expected to gain from the paradigm shift? The primary benefit should be in obtaining more productive engineers equipped with a better degree of mathematical preparedness for engineering problems. But in addition, it should also promote more intensive use of applied mathematics and easier communication with professional mathematicians, often needed in complicated industrial problems.?Finally, it can be noted that the new paradigm is in harmony with the basic ideas of the CDIO (Conceive - Design - Implement - Operate) initiative for producing the next generation of engineers [1]. New ideas for engineering education can be found also in the homepage of SEFI (European Society for Engineering Education) [2].

We extend the previous work [J. Korean Soc. Ind. Appl. Math. 21(3) 181] to two-and three-asset equity-linked securities (ELS). In the real finance market, two-or three-asset ELS is more popular than one-asset ELS. Therefore, we need to develop mobile platform for pricing the two-and three-asset ELS. The mobile implementation of the ELS pricing will be very useful in practice.

Experiment teaching is an important part for science and engineering colleges, teaching through different pilot projects: First, help students to consolidate the theory of operation; second, trail students the capacity and the ability to solve practical problems. Improve students the curriculum of learning, and promote the formation of students to discover and solve the problem. of the basic quality in training students hands-on ability and ability to innovate, while guiding them to develop the attitude of scientific truth-seeking, the style of rigorous and thorough and the spirit of unity and coordination.

본 연구는 대학의 전자공학과 학생들을 대상으로 수학 교과 내용과 전공 교과 내용의 연관성 및 수학교과 내의 선수 학습 내용과의 연관성을 이용한 공업수학 학습자료를 개발하고 이를 활용한 수학학습의 효과를 알아보는데 목적이 있다. 이러한 목적을 위해 먼저 전자공학과 전공 학습을 위해 필요한 공업수학 내용의 목록을 작성하고 이를 바탕으로 선수학습 내용 및 전공교과 내용과의 연관성을 조사한 후 연관성이 있는 내용을 학습자료의 주제로 선정하여 학습자료를 개발하였다. 그리고 개발된 학습자료를 이용하여 학습하게 한 후 학습자료에 대한 반응을 조사하고, 학습 태도에 대한 효과를 분석하였다. 그 결과, 학습자료의 도입부에 기술된 전공내용은 학생들에게 공업수학 학습에 대한 동기 부여에 도움을 주었으며, 공업수학 학습 내용 전에 기술된 선수학습 내용은 학생들에게 공업수학 학습내용의 학습에 집중하는데 도움을 주었다. 또한 개발된 학습자료는 학생들의 수학 학습 태도 중 수학 학습에 대한 자신감을 향상시키는데 효과가 있는 것으로 나타났다.

본 연구에서는 중위권 공과대학 신입생들의 수학에 대한 인식변화에 따른 대학수학의 교육방향을 연구하기 위하여 A대학교 공과대학 2011년과 2015년 신입생들을 대상으로 수학기초학력평가와 수학에 대한 인식 및 대학수학에 대한 설문을 실시하였고, 수학에 대한 인식변화를 고등학교 계열별, 대학수학능력시험 수학영역 응시유형별, 수학기초학력평가 성적별로 분석하였다. 연구 결과, A대학교 공과대학 신입생들은 수학기초학력이 부족한 것으로 나타났고, 2015년 신입생들은 2011년에 비해 자신이 느끼는 수학실력 수준이 향상되었고 대학수학 수업에서 더 노력하겠다고 답했다. 한편 2011년과 2015년 신입생 대부분이 대학수학은 전공을 위한 기초과목으로 인식하였고, 수업은 고등학교 중급 수준에서 시작하는 것과 교수가 이론설명 및 문제풀이도 해주는 수업방식을 선호했다. 본 연구 결과를 바탕으로 효율적인 대학수학 수업을 위해서는 교수 학습에서 수학기초학력의 향상에 초점을 두고 학생들 스스로 문제를 해결하는 학습태도를 강조해야 함을 제언하였다.
