block-based programming is an effective way to introduce students to computer science programming [3], [7], [8]. As the researcher community keeps lowering the barrier to entry, BBP environments now support learners as young as kindergarten (age 5) [1], [3]. block-based programming is designed to support novice learners by reducing syntax errors and supporting authoring with browsable and draggable commands. The design of BBP visually present commands that can only be fit together in the way that makes sense, just like LEGO bricks [7]. However, block-based programming is not the final goal for all learners, particularly for those who wish to pursue a career in computer science. As learners progress from elementary or middle school to high school or undergraduate studies, they are required to transition from the block-based programming environment to traditional text-based programming languages, such as Python or Java. This shift from block-based to text-based programming is not a direct one, and many learners encounter additional steps and concepts when they leave the block-based programming paradigm [4]. © 2023 IEEE.

This exploratory study attempts to determine problem solving steps in block based programming environments. The study was carried out throughout one term within ***. Participants were 15 6th grade secondary school students enrolled in an IT course at a public secondary school. Observations, screenshots and interviews were analyzed together to find out what students do and what they think during problem solving process. As a result, three main steps (focus, fight and finalize) were extracted from students' behavioral patterns. The results suggest that three steps occur in linear or cyclic manner with regard to the programming constructs required for the solution of the problem. Implications for instructors who desire to provide a better learning experience on problem solving through block-based programming are also included.

Free-choice, open-ended projects are commonly used to assess student learning in introductory block-based programming (BBP) environments. They are generally assessed in school based on criteria such as the social impact conveyed, whether the projects work without errors, and whether they are creative and engaging. Additionally, researchers have assessed such projects based on the frequency of use of various coding constructs like variables, conditionals, and iterations. This paper presents a novel multi-dimensional rubric for analyzing open-ended BBP projects that integrates assessment of front-end project design and back-end sophistication of use of coding constructs. Further, the novelty of the rubric lies in the fact that instead of relying solely on frequencies, it uses scaled scores based on sophistication of rubric components. Using this rubric, 160 Scratch and App Inventor projects were scored and analyzed. The paper establishes external validity of the rubric and examines what we can learn about student learning from this analysis. Our findings will help K-12 CS educators and curriculum developers recognize what aspects of CS middle school students need most support on, and how to leverage programming environments to provide this support.

programming in block-based environments is a key element of introductory computer science ( CS) curricula in K-12 settings. Past research conducted in the context of text-based programming points to several challenges related to novice learners' understanding of foundational programming constructs such as variables, loops, and expressions. This research aims to develop assessment items for measuring student understanding in introductory CS classrooms in middle school using a principled approach for assessment design. This paper describes the design of assessments items that were piloted with 100 6th, 7th, 8th graders who had completed an introductory programming course using Scratch. The results and follow-up cognitive thinkalouds indicate that students are generally unfamiliar with the use of variables, and harbor misconceptions about them. They also have trouble with other aspects of introductory programming such as how loops work, and how the Boolean operators work. These findings point to the need for pedagogy that combines popular constructionist activities with those that target conceptual learning, along with better professional development to support teachers' conceptual learning of these foundational constructs.

The time for battery-free computing is now. Lithium mining depletes and pollutes local water supplies and dead batteries in landfills leak toxic metals into the ground[20][12]. Battery-free devices represent a probable future for sustainable ubiquitous computing and we will need many more new devices and programmers to bring that future into reality. Yet, energy harvesting and battery-free devices that frequently fail are challenging to program. The maker movement has organically developed a considerable variety of platforms to prototype and program ubiquitous sensing and computing devices, but only a few have been modified to be usable with energy harvesting and to hide those pesky power failures that are the norm from variable energy availability (platforms like Microsoft's Makecode and AdaFruit's CircuitPython). Many platforms, especially Arduino (the first and most famous maker platform), do not support energy harvesting devices and intermittent computing. To bridge this gap and lay a strong foundation for potential new platforms for maker programming, we build a tool called BOOTHAMMER: a lightweight assembly re-writer for ARM Thumb. BOOTHAMMER analyzes and rewrites the low-level assembly to insert careful checkpoint and restore operations to enable programs to persist through power failures. The approach is easily insertable in existing toolchains and is general-purpose enough to be resilient to future platforms and devices/chipsets. We close the loop with the user by designing a small set of program annotations that any maker coder can use to provide extra information to this low-level tool that will significantly increase checkpoint efficiency and resolution. These optional extensions represent a way to include the user in decision-making about energy harvesting while ensuring the tool supports existing platforms. We conduct an extensive evaluation using various program benchmarks with Arduino as our chosen evaluation platform. We also demonstrate the usabili

Though the increased availability of Large Language Models (LLMs) presents significant potential for change in the way students learn to program, the text-based nature of the available tools currently preclude block-based languages from much of that innovation. In an attempt to remedy this, we identify the strengths and weaknesses of using a transpiler to leverage the existing learning in commercially available LLMs and Scratch, a visual block-based programming language. Using only prompt engineering, we evaluate an LLM's performance on two common classroom tasks in a Scratch curriculum. We evaluate the LLM's ability to: 1) Create project solutions that compile and satisfy project requirements and 2) Analyze student projects' completion of project requirements using natural language. In both cases, we find results indicating that prompt-engineering alone is insufficient to reliably produce high-quality results. For projects of medium complexity, the LLM-generated solutions consistently failed to follow correct syntax or, in the few instances with correct syntax, produce correct solutions. When used for autograding, we found a correlation between scores assigned by the official Scratch Encore autograder and those generated by the LLM, nevertheless the discrepancies between the 'real' scores and the scores assigned by the LLM remained too great for the tool to be reliable in a classroom setting.

There is agreement on the importance of teaching programming as part of the mandatory basic education (i.e., initial, primary and secondary school), as it gives tools to problem solving and abstract thinking, among other things. There are several programming tools that are usually used in schools, Scratch being one of the most famous. In general, Arduino boards are widely used in educational contexts, given their open hardware design as well as the myriad of technical and educational resources that are available freely, and that they allow to work with physical programming as well as with full scale projects. Arduino boards are usually programmed using the Arduino IDE, that is text-based, as well as with block based tools such as mblock, proprietary tools for Arduino-compatible boards and even extensions of Scratch. Those tools have limitations in order to be used in schools, given that they require the learning of text or block syntax, even when the latter has a softer learning curve. Particularly, some block programming tools are specific to certain kits or boards, do not include a variety of blocks for generic sensors and actuators, have very few blocks that facilitate the programming or are not available in widely used languages such as Spanish. In this work we present the block based Arduino programming Arduino en la Escuela (AelE, that could be translated from Spanish as "Arduino at the School"), that excels in versatility, given that it was used with students from ages, sociocultural context, as well as previous knowledge. The tool was used for courses mostly with secondary school students, but it was also applied in other contexts as with younger children and adults, as well as with teachers and even as part of a prison education program. In all these experiences AelE was well accepted by the students, and the tool was totally suitable in order to complete the required class assignments as well as to work with projects of different kinds.

Battery-free MakeCode: Accessible programming for Intermittent Computing

PROCEEDINGS OF THE ACM ON INTERACTIVE MOBILE WEARABLE AND UBIQUITOUS TECHNOLOGIES-IMWUT 2022年第1期6卷 1–35页

Hands-on computing has emerged as an exciting and accessible way to learn about computing and engineering in the physical world for students and makers of all ages. Current end-to-end approaches like Microsoft MakeCode require tethered or battery-powered devices like a micro:bit, limiting usefulness and applicability, as well as abdicating responsibility for teaching sustainable practices. Unfortunately, energy harvesting computing devices are usually only programmable by experts and require significant supporting toolchains and knowledge across multiple engineering and computing disciplines to work effectively. This paper bridges the gap between sustainable computing efforts, the maker movement, and novice-focused programming environments with MakeCode-Iceberg, a set of compiler extensions to Microsoft's open-source MakeCode project. The extensions automatically and invisibly transform user code in any language supported (blocks, JavaScript, Python)into a version that can safely and correctly execute across intermittent power failures caused by unreliable energy harvesting. Determining where, when, and what to save in a checkpoint on limited energy, time, and hardware budget is challenging. We leverage the unique intermediate representation of the MakeCode source-to-source compiler to design and deploy various checkpointing techniques. Our approach allows us to provide, for the first time, a fully web-based and toolchain-free environment to program intermittent computing devices, making battery-free operation accessible to all. We demonstrate new use cases with multiple energy harvesters, peripherals, and application domains: including a Smart Terrarium, Step Counter, and Combination Lock. MakeCode-Iceberg provides sustainable hands-on computing opportunities to a broad audience of makers and learners, democratizing access to energy harvesting and battery-free embedded systems.

Many block-based programming environments have proven to be effective at engaging novices in learning programming. However, most offer only restricted access to the outside world, limiting learners to commands and computing resources built in to the environment. Some allow learners to drag and drop files, connect to sensors and robots locally or issue HTTP requests. But in a world where most of the applications in our daily lives are distributed (i.e., their functionality depends on communicating with other computers or accessing resources and data on the internet), the limited support for beginners to envision and create such distributed programs is a lost opportunity. We argue that it is feasible to create environments with simple yet powerful abstractions that open up distributed computing and other widely-used but advanced computing concepts including networking, the Internet of Things, and cybersecurity to novices. The paper presents the architecture of and design decisions behind NetsBlox, a programming environment that supports these ideas. We show how NetsBlox expands opportunities for learning considerably: NetsBlox projects can access a wealth of online data and web services, and they can communicate with other projects. Moreover, the tool infrastructure enables young learners to collaborate with each other during program construction, whether they share their physical location or study remotely. Importantly, providing access to the wider world will also help counter widespread student perceptions that block-based environments are mere toys, and show that they are capable of creating compelling applications. In this way, NetsBlox offers an illuminating example of how tools can be designed to democratize access to powerful ideas in computing.

This article proposes the BIPES, a block based Integrated Platform for Embedded Systems, including its architecture, design and validation results. BIPES is an open source software and service that is freely available through the website http://*** and has been conceived from our experience of several years developing embedded systems and Internet of Things (IoT) applications, and teaching. It allows anyone to quickly and reliably design, program, build, deploy and monitor embedded systems, IoT devices and applications using blocks or Python based programming. It is fully based on web environment, so absolutely no software installation is needed on the client developer machine. In this way, a tablet, a netbook, a Chromebook or any other device can be used to program and test several types of devices. Mainly, it relies on MicroPython or CircuitPython, WebREPL, WebSockets, Web Serial API, HTML, JavaScript and Google blockly to allow no-code programming (blocks) to be translated into Python code and then deployed to the target board. Moreover, it does not require server side processing, so it can be deployed as a Progressive Web Application (PWA), allowing it to be used even when the computer is offline. It is compatible with several low cost boards such as: mBed, BBC micro:bit, ESP8266, ESP32 and Raspberry Pi using only a web browser and without the need to install any software on the device where the user develops the programming.
