The purpose of this research is to compare textual programming languages and visual programming languages from the aspect of motivation. As a textual programming language, Processing programming language was used, and as visual programming languages, Scratch, a derivation of Scratch, Teaching materials offered by ***, and LEGO Mindstorms EV3 were used. Teaching materials using the textual programming language, and those using the visual programming languages were developed separately. A trial experiment of programming education with the textual programming language was conducted to a cohort of seven primary schoolchildren. Trial experiments with the visual programming languages were conducted twice. In each of them, a cohort of eight primary schoolchildren participated. The motivation of the children was assessed using the questionnaire based on the ARCS (Attention, Relevance, Confidence, and Satisfaction) motivation model. The results with the visual programming languages suggested that the motivation scores of the children increased as the class progressed when visual programming languages were used. On the other hand, the results with Processing suggested that the variance of Satisfaction factor increased as the class progressed when textual programming languages were used, which further suggested that the Satisfaction scores of the children spread as the class progressed when textual programming languages were used.

In this paper, we combined a visualization tool and Dr. Scratch website service to support instructors evaluating the Scratch projects on an online social networking forum: ***. Scratch is a visual programming language used by youth to design programs like animation, game, or music. Their computational thinking skills take place around program decompositions, program patterns, and data representation in the shared Scratch programs (called projects). Through the exploratory work, we found that some cues, such as deep nested iteration, may be successfully used as indicators of users' computational thinking skills. This suggests future directions for assessing youth's computational thinking skills development and educational opportunities emerging from shared Scratch projects.

Workflow diagrams consist of nodes and connectors to express the steps of processing in the form of a visual program. The graphical vocabulary and the layout of the diagram have an influence on the user cognition of diagram. The aesthetic aspects also have an impact on users understanding. One aesthetic recommendation - "minimize beds in edge" was tested in workflow diagrams from ArcGIS ModelBuilder. Eye-tracking measuring in the laboratory was prepared for objective empirical testing. Five couples of diagrams with and without orthogonally bends were showed to 26 respondents. The user executed specific tasks above diagrams. Eye-tracking measuring brought interesting objective results. Eye-tracking metrics affirm that diagrams with orthogonal bends on connector lines have an average higher number of fixations, longer length of scanpath, shorter average time of fixation and longer duration time. The result is that the using of straight lines brings effective cognition of workflow diagrams in case of spatial data processing in geographic information system (GIS).

As the needs of education of programming language increase, the importance of the learning environment has been emphasized. Based on the social trends, various web services for the education of programming which improves the computational thinking of a student. Among the web services, block-based programming languages are well known as an effective educational tool for a primary student though a freshman in the university. These tools are proven to be useful tools since the tools provide same programming environment to the students and the teachers anytime and anywhere. However, the environments may be insufficient for learning practical programming languages, such as C/C++ and Java, because they are not the block-based programming languages. This paper introduces a block-based learning environment for C programming language using web services. The environment fills the gap between building computational thinking and learning the syntax of the programming language. The programming environment provides the equivalent environment to teachers and the students during the programming hands-on.

Title: visual programming Backend for a Mobile Robot Author: Bc. Ondřej Staněk Department: The Department of Software Engineering Supervisor: RNDr. David Obdržálek, Ph.D. Supervisors e-mail address: ***@*** Abstract: In this work, the author designs and implements a solution for programming small mobile robots using a visual programming language. A suitable visual programming front-end is selected and back-end layers are created that allow execution of the program in a mobile robot. The author designs and implements a virtual machine that runs alongside the original robot firmware on an 8-bit microcontroller with limited resources. A code generator layer compiles the visual representation of the program into a sequence of bytecode instructions that is interpreted on board of the mobile robot. The solution supports typical features of procedural programming languages, in particular: variables, expressions, conditional statements, loops, static arrays, function calls and recursion. The emphasis is put on robustness of the implementation. To verify and maintain code quality, methods of automated software testing are used.

The availability of embedded, digital systems has led to a multitude of interconnected sensors and actuators being distributed among smart objects and built environments. programming and understanding the behaviors of such systems can be challenging given their inherent spatial nature. To explore how spatial and contextual information can facilitate the authoring of intelligent environments, we introduce Ivy, a spatially situated visual programming tool using immersive virtual reality. Ivy allows users to link smart objects, insert logic constructs, and visualize real-time data flows between real-world sensors and actuators. Initial feedback sessions show that participants of varying skill levels can successfully author and debug programs in example scenarios.

The development of audio application demands a high knowledge about this application domain, traditional programming logic and programming languages. It is possible to use a visual programming language to ease the application development, including experimentations and creative exploration of the language. In this paper we present a visual programming Environment to create Web Audio applications, called Mosaicode. Different from other audio creation platforms that use a visual approach, our environment is a source code generator based on code snippets to create complete applications.

In this document we describe the development of a remote lab and two user interfaces for teaching programming and fundamentals of robotics using Arduino boards. One of the interfaces uses visual language to make the experience more attractive for those who are beginning their studies. The second interface provides an environment similar to the original Arduinos one for those users who have some background to use textual programming language. In addition, we present an usability evaluation of the application using visual programming language to obtain a broad feedback mainly in terms of target audiences acceptance and suggestions for improvements. The environment is still an ongoing work, but it is suitable for courses and workshops, especially for institutions with limited resources.

The proliferation of ubiquitous computing has led to the development of various types of sensor devices for human-computer interaction (HCI). However, the availability of developer tools is lacking in comparison with the development of sensor devices. This shortcoming has been partially addressed by the introduction of open source hardware but it is difficult to develop applications using this alone. In this paper, a framework for sensor device application development has been illustrated by using a visual language and interconnections between the PC and target board.
