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.

It is not sufficient to give a lecture in programming language without programming practice since lectures on programming must be given at lecture room with H/W and S/W for programming. In this paper, learning for Visual Basic programming has been designed and embodied with the leveled learning system in order to give an effective and positive result to both teacher and learner under the constructivism theory of education (Problem Based learning, Self-Directed learning) for the theoretical basis of the seventh education curriculum. We implemented a web courseware for Visual Basic programming using ActiveX and Tutor System. As the result of education using this courseware, it is verified as a leveled education method to adapt the learning ability of individual students, and it can raise the achievement, enthusiasm of learning and provide various opportunity of education with this various education methods. Also it enhances the problem solving ability and the logical thinking power by providing students with error correction learning.

Data structure and algorithm are primary courses for computer programming instruction. However, now those are not interesting courses for students because the programming instruction methodologies that used these courses are not the proper methodologies for the visual and windows programming. The Sorting programming is the same as other data structures. Therefore, we developed the VTSPI (Visualization Tool for Sorting Programming Instruction) which is a software component to instruct sorting program effectively for solving these problems. As a result, students can code, understand and debug their programs because VTPSI is software components based on visual programming.

The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test and construction of simple silhouette figures. Then camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

The purpose of this study is to utilize new way of learning, Problem-Based Learning, for learning of VisualBasic programming. Providing authentic problems is a critical factor for programming learning because the skill may be not such a simple command learning but includes a variety of complexity. The objective of the learning is to develop quiz using VisualBasic programming. With programming skill, students was expected to solve the problem through peer collaboration activities as well as evaluation by peer and group composites. According to descriptive survey, it is concluded that students figure out their own learning status clearly. Furthermore, improvement of learning attitude and participation affect satisfaction and self-confidence.

Reliability-based structural optimization usually requires designers or engineers model different designs manually, which is considered very time consuming and all possibilities cannot be fully explored. Otherwise, a lot of time are needed for designers or engineers to learn mathematical modeling and programming skills. Therefore, a framework that integrates generative design, structural simulation and reliability theory is proposed. With the proposed framework, various designs are generated based on a set of rules and parameters defined based on visual programming, and their structural performance are simulated by OpenSees. Then, reliability of each design is evaluated based on the simulation results, and an optimal design can be found. The proposed framework and prototype are tested in the optimization of a steel frame structure, and results illustrate that generative design based on visual programming is user friendly and different design possibilities can be explored in an efficient way. It is also reported that structural reliability can be assessed in an automatic way by integrating Dynamo and OpenSees. This research contributes to the body of knowledge by providing a novel framework for automatic reliability evaluation and structural optimization.

Web programming courses are often included in university Computer Science programs as introductory and foundational computer programming courses. However, amateur programmers often have difficulty learning how to integrate HTML, CSS, JavaScript, and various preprocessors or libraries to create websites. Additionally, many web programming mistakes do not produce visible output in the browser. Therefore, in recent years, Front-End Code Playground (FECP) tools that incorporate HTML, CSS, and JavaScript into a single, online web-based application have become popular. These tools allow web coding to happen directly in the browser and provide immediate visual feedback to users. Such immediate visual feedback can be particularly beneficial for amateur coders to learn and practice with. Therefore, this study gathers data on various FECP tools, compares their differences, and provides an analysis of how such tools benefit students. This study concludes with an outline of the application of FECP to web programming courses to enhance the learning experience.

In the future society where ICT-based digital convergence creates new value, collaborative skills among experts in various fields and SW based problem solving ability is more emphasized. Non-SW specialists are required to have SW based communication skills to effectively collaborate with SW experts to solve their problems. Therefore, SW programming curriculum for non-major college students should be different from the existing programming education for SW-majors aiming at a high level of coding ability. It is also known that diagram-based visual representation is helpful for productive communication and collaboration. In this study, we defined the SW education objectives for the non-majors as cultivating the visual programming ability for SW based problem solving. In order to accomplish this, we explored SW programming curriculum and content development model for non-majors focusing on visual representation of SW solutions. The results of this paper will help to provide appropriate SW learning model for non-majors and to cultivate practical SW capabilities.

Recently, with an emphasis on software proficiency, universities are providing software education to all students regardless of their majors. However, non-majors often lack motivation for software education and perceive the unfamiliar learning content as more challenging. To address this issue, tailored software education according to the learners' characteristics is essential. Art students, for instance, with their strong visual comprehension and expressive abilities, can benefit from utilizing visual literacy to enhance the effectiveness of programming education. In this study, we propose decomposing everyday problems into flowcharts and pseudocode to construct procedural and visual images. Using the educational programming language PlayBot, we aim to analyze the effectiveness of teaching by coding to solve problems. Through this approach, students are expected to grasp programming concepts, understand problem-solving processes through computational thinking, and acquire skills to apply programming in their respective fields.
