The paper describes how the built-in tools for stochastic dynamic control of the computation process in a programming paradigm, named Control Network programming (CNP), could be used to achieve declarative (non-procedural) implementations of a genetic algorithm. As these implementations are very intuitive and easily programmed, CNP can be used as an excellent approach for teaching, learning and programming the basic model of the genetic algorithms. They are presented on the well-known 8-queens problem often used as an example problem for various programming techniques, including non-traditional approaches such as genetic algorithms. More specifically, the emphasis is on automatic, non-procedural modelling of certain selection operators such as roulette wheel selection and rank selection, as well as the Bernoulli trial, used in crossover and mutation operators.

Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to instruments for formative assessment that potentially improve the quality of learning. This study contributes to these issues by developing the assessment for learning of CT via Scratch in primary school settings. A review on prior studies involving the assessment of CT-related computational ideas in Scratch has led to the conceptualization of a revised assessment framework. Next steps in the study are analyzing fourth grade students' (N=58) Scratch projects and exploring complementary methods for analyzing CT in video recordings of the students' programming processes.

This paper presents the FPGA implementation results of the LMS algorithm with complex input/output data. The implementation is fulfilled based on Xilinx system generator in a graphical programming manner, and demonstrated on Xilinx KC705 evaluation board. It is shown that complex LMS algorithm, regardless of the order of filter, can support more than 200 million-samples-per-second (Msps) throughput rate when 16-bit complex input/output data are considered, with latency of 3 or 4 clock periods (i.e. 15ns or 20ns when clock frequency is 200MHz).

As the engineering education and computer technologies for industry merge, the opportunities for teaching and learning will also expand. In such context, a large number of academic courses that teach electrical engineering concepts have incorporated the graphical programming as educational tool for student use. The current paper discuses some of the most popular graphical programming packages, identifies two alternative solutions and shows how the virtual instrumentation approach pioneered by LabVIEW may enhance the electrical engineering curricula.

As more elementary schools commit to integrating computer science instruction into their curricula, they seek guidance on what concepts are appropriate for students at different grade levels. Currently, little is known about how best to sequence computer science learning across elementary grades. In this paper, we present an analysis of 123 students' ( age 9-12, grades 4-6) activities in a curriculum implemented in a visual block-based programming language. The goal of this work is to better understand the developmental appropriateness of foundational computer science ideas. All 4th, 5th, and 6th grade students in a single school completed the first module of a curriculum during the same school year with the same instructor. We analyzed each task students attempted and found that for simple concepts, there was little difference in performance between grade levels. However, differences were found for more complex topics, such as whether they completed initialization tasks and the way in which they solved 2-d navigation tasks. A closer look revealed that students understood the basic concepts, but were challenged by deeper applications of the basic concepts and influenced by non-computer science skills. This work serves as an empirically grounded investigation of elementary computer science learning and contributes to our understanding of computer science learning trajectories and concept sequencing in the late elementary grades.

In this paper, we present an analysis of 123 students' (aged 9-12) digital stories created in a visual block-based programming language across three grade levels (grades 4-6). These students were all involved in the same introductory computer science curriculum. Participating students attended the same school and received computer science instruction from the same teacher within the context of the academic day. We analyzed each project for the extent of user-centered design that the student programmed. Specifically, we identified two components of user-centered design: 1) the programmed control choices students used, and 2) if/how they communicated those mechanisms of control to the user. Our work indicates that students in fifth and sixth grade (aged 10-12) used higher diversity of event blocks and coordinated action across multiple sprites at a higher rate compared to fourth grade students (aged 9-10). In contrast, fourth grade students tended to create more simplistic programs, rarely coordinating actions across multiple sprites. This work suggests that the construct of user-centered design within visual block-based programming languages is more complex than previously indicated. Additionally, explicit instruction about user-centered design is necessary, but may be more effective when a student reaches the age of 10 or 11 years old.

This paper proposes an education robotic platform that aims to improve teaching methods of programming and robotics skills, for both beginner and advanced users. We propose an innovative platform that consists of a versatile set of sensors and actuators, controlled by utilizing a user-friendly visual programming language through a mobile phone interface, or by utilizing a representational state transfer application programming interface for more advanced users. Suggested methods form the foundation of problem-based learning, by emphasizing hands-on experimental assignments and activities, and collaborative learning. We present the software and hardware architecture of the system, and case studies for utilizing different control modes. Consequently, students can improve their understanding of basic robotic concepts by observing real-time response and feedback of the actuator and sensor modules integrated in the robotic platform.

Service-oriented computing and service-level orchestration through visual or graphical programming have been widely used in software and particularly in Web application development. Their further developments and fusing into Internet of Things, Robot as a Service(Raa S), cloud computing, and big data analysis have created the infrastructure for the information technologies to penetrate into all sectors of industry, service, and society. Figure 1 shows the stack of the related concepts, technologies, and *** T service orchestration and visual programming separates the high-level composition from the low-level device programming, which allows the application builders to focus on the business logic, while the service providers to focus on efficient service development. This presentation will discuss the current service orchestration and visual programming environments for Io T application development. The presentation centralizes the topics around Io T. It starts with the upper layer of Io T, including service-oriented computing, Web software development, and service orchestration for system integration, which forms the foundation of cloud computing and a major data source of big data analysis. On the other hand, Io T standards and protocols are presented, which connect the service orchestration infrastructure tohardware and devices. As Io T applications and implementations, ADS(Autonomous Decentralized Systems), DPWS(Device Profile for Web Services), and Robot as a Service will be discussed. Different orchestration environments that have been widely used in industry and academic world will be presented, including BPEL in Oracle SOA Suite, Microsoft Workflow Foundation, Intel Io T Service Orchestration Layer, Microsoft Robotics Development Studio, MIT App Inventor, CMU Alice visual game programming environment, and ASU VIPLE(Visual Io T/Robotics programming Environment). As a case study, VIPLE will be presented in more detail. VIPLE is a free software with

In this paper, we present our analysis of 92 fourth graders' digital story projects completed in LaPlaya, a Scratch-like programming environment. Projects were analyzed for the way that students programmed the start of the story, and if the program integrated user-centered design by providing instruction to the user on how to interact with the digital story. We found that fourth grade students rarely used user-centered design while creating digital stories in our block-based programming environment. Without explicit instruction, the demands of learning programming and simultaneously programming for an abstract user may be too cognitively demanding for the average fourth grader.
