This study developed HanScript, which is an educational Hangul programming language, in order to make programs easily and conveniently and applied it to the school fields. To evaluate HanScript, additionally, the researcher divided the properties of educational programming languages into easiness to read, easiness to write and easiness to debug and, based on them, compared HanScript with Visual Basic. According to the result, HanScript was expressed in Korean language style, so was easier to read and debug than Visual Basic. But it was not different from Visual Basic in debugging. Due to fewer libraries compared to Visual Basic, however, it was difficult to implement complex functions using HanScript. In addition, HanScript did not include an editor to edit source codes. Thus, if HanScript is equipped with rich libraries, detailed debugging information and an editor for source code edition, it will be a useful educational programming language.

Programming novices have various difficulties when they learn C language for the first time. Novices have a large burden for understanding of a C language grammar, and have a tendency to focus on the grammar rather than problem solving. Moreover, it requires programming domains to arouse student's interest for software development. This paper presents a programming environment for C languages education focusing on a problem solving. To this end, this paper defines Tiny-VPL that is a simple visual programming language for NXT robot programming and presents robot programming environment using Tiny-VPL. This paper also presents an environment for NXT robot programming using Mini-C language which is a subset of C language. For the purpose of helping to understand the C syntax and semantics, the visual and interactive conversion system of Tiny-VPL to Mini-C is provided. Our programming environment can arouse student's interest through robot programming and can be used effectively for C language education focusing on problem solving with graphical and interactive conversion of the visual language Tiny-VPL to the textual language Mini-C.

To learn a programming language as a text-based programming and a computer language suitable for a wide range, learner thinks it is very difficult. To represent a visual program is one way to solve this problem easily. The visual language such as Visual C++, Visual Basic and Delphi is represented an interface as the visual component and represented a component action as a text-based. The programmer is very difficult about the component action with text-based and dislikes programming. In this paper, so solve these problems, we use the UML for representing a logical thinking and supporting and object-oriented programming. We suggest for programming education method to replace text-based programming to LabVIEW OOP. In addition, we conduct a survey on how programming education and analyze the training effect.

The trend of using Grasshopper with Rhino3D actively in architectural design process is recently spreading around the world. Well-known architects and designers such as Zaha Hadid, Patrik Schmacher is famous for using Grasshopper as their main design tool. As a tool for so-called 'Parametric Design', Grasshopper is receiving much attention all over the world. Grasshopper as a visual programming language has an advantage that designers and non-professionals of computer can easily learn it and use it to their works. However, those designers tend to make inefficient approaches with Grasshopper compared to computer programming professionals. Meanwhile, the difference between other programming languages and Grasshopper leads to the need of different approaches from other programming languages. This study aims to propose desired approaches of Grasshopper programming or scripting to be able to break through the inefficient approaches that designer is likely to make, by examining the characteristics of Grasshopper and exploring the appropriate programming approaches for Grasshopper.

So far, previous works with respect to evaluating program contents have concentrated on the implementation of general educational content evaluation. In terms of the efforts required to solve problems, however, there are a few evaluation methods on educational programming language contents. Therefore, we propose new evaluation criteria for educational programming language contents. The detailed research contents can be summarized as follows. First, we analyze existing works and propose naval evaluation criteria for educational programming language contents. Second, the new evaluation criteria is verified by teachers who use Visual Basic educational contents via questionaries. Also, a program content is experimented via the evaluation criteria. Finally, it is expected that our proposed evaluation criteria for educational programming language contents can be used to evaluate newly developed educational programming language contents and to design its evaluation plans.

In this paper, we developed an e-loaming contents for C programming language using Linux and open source software, not using commercial integrated development tool like Microsoft's Visual Studio. In most programming language courses, students study or practice the programming language by editing source code compiling and running the executable code by commercial software like Visual Studio which installed on each PC. This way of learning has some difficulties in total cost of purchasing software and using other PCs which donot have proper software installed. To overcome this situation and enable loaming anywhere, with any device, at anytime, we propose a way of utilizing Linux and open source software in Web-based learning environment. In this environment students can input their source code on the form of broweser and get the result instantly from the server.

A visual concurrent programming environment, called ESTGVP is designed and implemented, which is easy to understand, highly portable, and can represent parallel behaviors. For our purpose, a conventional state transition graph is extended so as to enable both of synchronous and asynchronous parallel operations. We call it extended state transition graph (ESTG). ESTGVP uses the ESTG and texts for programming, and makes it easy programming sequential and parallel behaviors. Also, it is easy to understand the control structure of a program because ESTGVP is a visual programming environment based on the graph. ESTGVP is written in Tel language and thus it is highly portable on various operating systems. It consists of three major components; edition, transformation and execution. If necessary, ESTG can be transformed into C or Tel language, and its execution is based on Tel.
