  • The purpose of this study is development of 'F1 in Schools Program' for elementary school student and validation of the program. Fifteen students were originally chosen from the W elementary school in Cheongju, Chungcheogbuk-Do. The children were tested on their understanding of science and 'F1 in Schools Program'. After developing the 'F1 in Schools Program', it was used in the classroom to evaluate applicability and to examine the responses from students, parents and schools. The program consists of 60 classes and the time of each class is 40 minutes. This study was conducted for 10 days from January 22nd, 2007 to February 2nd, 2007. CAD(Computer Aided Design), CFD(Computation Fluid Dynamics), CAM(Computer Aided manufacturing) and CNC Machine were used in this study and proved to be good materials for students in that they increased the students' participation and imagination. However, the children's cognitive and creative abilities as well as manuals written in English hampered the process. Most students, parents, schools seemed to be satisfied with use of the program. However, the schools showed that there was not enough understanding of the program as a whole. The processes with which students build and inspect using the $CO_2$Model Car not only improves the processing of the model but also enhanced the students scientific understanding related to the car speed.

  • It is information age now. Computer technology increases productivity, efficiency, and convenience of the public. Even if the computer-aided mathematics education is very important, so far there is the meager level of applying computers to mathematics education. This paper proposes a learning system with authoring tool for mathematics education. Teachers make study-contents easily with the system, and use them on a class. The content database that stores study-contents extends the usability of the system.

  • Recently, 3D printing has received increasing attention due to its boundless potentials. Because 3D printing starts from 3D geometry information, computer-aided design (CAD) is an essential technology to build 3D geometry data. These days, education of 3D CAD for engineering students has been changed from the theoretical lecture to practical design training using commercial CAD software. As a result, open-ended design projects have replaced the traditional theoretical examinations to evaluate students' outcomes. However, such design projects are not enough to evaluate students' outcomes because their results are expressed in two-dimensional ways. In this paper, applications of 3D printing in engineering design education are discussed by describing the procedure and outcomes of design projects. It was found that the use of 3D printing could improve students' outcomes by fabricating real physical models out of their designs.

  • In this paper, we present a new environment of learning and teaching of trigonometric, exponential and logarithmic functions, the most difficult parts for students to learn among functions, through sound and music, students like the most. First, by using sound and music, we try to arouse student's interest. Second, we let students see and hear properties of transcendental functions so that students can understand and remember them easily. Finally we encourage students to compose their favorite song using transcendental functions so that they can experience the practicality of transcendental functions.

Also, computer is interacting, and adapts spontaneously in current enemy these age by important means on information-oriented society that change rapidly and computer-aided education is essential to improve country competitive power. Grasp computer education actual conditions of vocational high school for positivity that is industrial technology that IT base knowledge information-oriented society requires in this research hereupon, and though students' profession preference wishes to supply pabulum in course education presenting improvement direction of more efficient computer-aided education through investigation, there is the purpose. In present school curriculum, satisfaction about computer connection education responded that have interest much very appeared in general high. Also, computer connection profession preference was expose that research results keep in step and prefers most Information Communication Technology (ICT) field and multi media field that is embossed newly in post-industrial society.

  • For students majoring in Architecture or Architectural Engineering, describing a building with pictures and signs is equal to expressing his/her opinion with sentences and presentations. CAD (computer aided design) is a method of describing buildings, and is used practically in architecture-related companies. Many universities prescribe CAD instruction as a compulsory subject, and ABEEK (Accreditation Board for Engineering Education of Korea) requires an introduction to CAD as a basic subject for visual expression. The Architectural Drawing and CAD class in the department of Architectural Engineering of J University is a 2-credit course, with 4 hours of lectures per week. Relative to other subjects, this is insufficient for practical study. Thus, to make up for this insufficient time, the class has adopted a Blended learning system that mixes off-line and on-line classes. The objective of this research is to introduce Blended learning, and to give a case study of the CAD class using Blended learning.

  • A survey of small-size contractors in Jeju was conducted to investigate college graduate's CAD (computer aided design) competence. Most of small-size contractors use CAD softwares to review and update drawings submitted from an architect. This research analyzed the curriculum of the architectural engineering in several national universities. The CAD classes have 4 or 6 hours per week and use AutoCAD primarily. This research proposes that a CAD class needs at least 6 hours per week, 2D drawing is the main theme in the curriculum, and exercises to make 3D models are also included in the CAD class. The improved methods, Internet cafe and real time feedbacks using a smartphone, to evaluate the reports and exercise results are necessary.

  • Since the computer is becoming more and more indispensible tool in every fields of the modern society, it is needed and desirable to utilize the computer as a basic tool from the very early stage of the education process. Recently Maple is gaining its popularity as a comprehensive mathematical software with its power of symbolic calculations and graphics as well as its great numerical computational ability. We demonstrate the suitability of this software as a tool for the mathematical education and presents several examples of the applications of Maple. For the middle and the high school mathematics courses, we give the application examples for the quadratic functions and their graphs, statistics, the three dimensional shapes, algebraic problems. Through the examples, we confirm that mathematical education can be much more effective and simple by using Maple. If we establish computer-assisted mathematical classes, we can draw more attention and excitement from the attendants than traditional classes and eventually improve more rapidly their problem-solving ability On the other hand, the excess of the computer-aided education give to obstacle of psychological, not to be passing over the fact.
