We propose a unmaned integrating control system based-on Windows XP version Off-Line Programming System which can simulate a Robot model in 3D Graphics space in this paper. The industrial robot with 4 and 6 axes modeled SM5 and AMI respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off-line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

The robot with 4 and 6 axes modeled SM5 and AM1 respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off$.$line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.

In this study, 37 elementary, middle, and high school science teachers attending graduate schools of education were surveyed about their thoughts about the difficulty of teaching science units and teaching methods to teach these units to students. After experiencing the activity of making new teaching tools using scratch, we tried to confirm the development of TPACK among the teachers. Through the questionnaire survey for elementary, secondary, and high school science teachers, we selected the unit of Planetary Movement of the Solar System as a unit that is difficult for teachers to teach. We gave them the experience of instruction on tool making process for implementing a planetary operation model using scratch. Then, based on the questionnaires and class presentations, we analyzed the change of awareness about technology introduction and the development of their TPACK. As a result, most of the teachers showed changes of perceptions related to TK, TCK, TPK; the use of programming for creating teaching materials enhances teachers' understanding of the teaching contents; the teachers were convinced that students would develop the ability to construct models that fit observational phenomena; they thought that there would be a positive educational effect in the positive domain.

A programming language is very important subject in computer science. But it is difficult for many students to learn programming language. New pedagogical methods and techniques to help students to learn programming are needed. In this paper, we investigated the effects of Pair Programming, and we proposed a Pair programming strategy to improve programming skills. This paper examined the proposed Pair programming strategy. A empirical study showed the proposed teaching and learning strategy has positive effects on achievement and motivated strategies in programming course. Four factors - critical thinking, metacognitive reflection, effort regulation, and peer learning - have positive effects in learning strategies. The proposed Pair Programming strategy improves programming learning and motivated strategies.

An integrated Robot control system for SCARA robot is developed. The system consists of an off-line programming(OLP), software and a robot controller using four digital signal processor(TMS32OC50). The OLP has functions of teaching task, dynamic simulator, three dimensional animation, and trajectory planning. To develop robust dynamic control algorithm, a new sliding mode control algorithm for the robot is proposed. The trajectory tracking performance of these algorithm is evaluated by implementing to SCARA robot(SM5 type) using DSP controller which has conventional PI-FF control algorithm. To make SCARA robot operate according to off-line teaching, an interface between OLP and robot controller in the integrated system is designed. To demonstrate performance of the integrated system, the proposed control algorithm is applied to the system.

Computer technology in mathematics teaching-learning is not for teaching computer but for improving mathematics teaching-learning with computer. It is shown the use of computer technology comparing with traditional approach provides students more opportunities in order to approach abstract structure. Computer activity provides not only understanding concepts of analysis and opportunity to investigate theory but also effective background in teaching analysis. We analyze students' computer usage level on analysis education by using computer usage level according to role of computer technology. We try to get an useful educational implication on analysis education applying MATLAB through qualitative research.

Arduino makes it easy to connect objects and computers. As a result, programming learning using physical computing has been proposed as an effective alternative to SW training for beginners. In this paper, we propose an Arduino-based physical computing education method that can be applied to basic programming subjects. To this end, we propose a basic programming training method based on Arduino analog signals. Currently, physical computing courses focus on digital control when connecting input sensors and output devices in Arduino. However, the contents of programming education using analog signals of Arduino boards are insufficient. In this paper, we proposed and tested the teaching method used for programming education using low-cost materials used for Arduino analog signal-based computing.

In this paper, teaching object-oriented design in a programming course is a big challenge for instructors. "Objects-first" is a popular strategy for teaching object-oriented programming in the educational settings, by introducing the concepts of objects, classes, and instances before procedural elements of a programming language. Still, this approach emphasizes coding rather than other critical aspects of software development, notably problem-solving and design. We propose a "design-first" approach, which subsumes an objects-first approach into lessons that also introduce object-oriented analysis and design, using elements of UML before implementing any code. We also present video rental store (SRS) that uses the design-first approach to help students of various teaming styles in a software engineering course. It interfaces with an IDE we have chosen specifically to support the design-first approach, and SRS which has been shown to be effective in helping students learn object-oriented programming concepts.

Object Oriented Programming Languages including Java require Object-oriented thinking first for programming. However, for Korean students it is not easy since they are fully accustomed to Korean language which does not have the Object-oriented concept. This paper proposes a way of teaching the Object Oriented Languages to Korean students. It explains first how to organize our thoughts in Object-oriented way, and then how to express the thoughts with the languages.
