Context: Object-Oriented programming design patterns are well-known in the industry and taught in universities as part of software engineering curricula. Many primary studies exist on the impact of design patterns on software, in addition to secondary studies summarizing these publications. Some primary studies have proposed new language features and used them to re-implement design patterns as a way to show improvements. While secondary studies exist, they mainly focus on measuring the impact of design patterns on software. Objectives: We performed a systematic mapping study to catalogue language features in the literature claiming to improve object-oriented design patterns implementations, as well as how primary studies measure these improvements. Methods: We performed a search in three databases, yielding a total of 874 papers, from which we obtained 34 relevant papers. We extracted and studied data about the language features claiming to improve design patterns implementations, the most often cited design patterns, the measures used to assess the improvements, and the case studies and experiments with which these improvements were studied. Results: Using the results, we catalogue 18 language features claimed in the literature to improve design patterns and categorize them into paradigms. We find that some design patterns are more prevalent than others, such as Observer and Visitor. Measures related to code size, code scattering and understandability are preferred. Case studies are done in-vitro, and experiments are rare. Conclusion: This catalogue is useful to identify trends and create a road map for research on language features to improve object-oriented design patterns. Considering the prevalence of design patterns, improving their implementation and adding language features to better solve their underlying concerns is an efficient way to improve object-oriented programming. We intend in the future to use this as a basis to research specific language feature

This Research Full Paper addresses the definition and implementation of Computational Thinking (CT) in K-12 education. CT is the focus of ongoing debate about the future of computing in schools, and this poses a number of challenges. Early discussions on the topic were plagued by vague and all-encompassing definitions of the term, which raised awareness of a need for school learning focused on emerging computational systems and their impact on society and the lives of citizens, but failed to address what should actually be included in the revised curricula. As some of those issues have been addressed, a number of problems remain. This paper analyses some recent and future developments in the field of computing, and expands the discussion on the vexed question of the nature and limits of computational thinking. We ask whether the current mainstream literature and curriculum for CT is well positioned in terms of the future towards which computing is heading. We conclude by summarising the implications these questions have for the future development of K-12 curricula and teaching practices.

Spring 2023 marks 10 years since \snap was first used with students, and the Snap! Cloud was developed for sharing projects. Since then, nearly 700,000 students and educators have worked on more than 6 million Snap! projects. This BOF serves as an opportunity to meet with the large community of Snap! users that attend SIGCSE. The past three releases have focused on power ideas, such as native array-based data programming, building microworlds, and metaprogramming. We want to have a chance to share success stories, and then discuss: what's next?Notes, projects and examples from this BOF will be shared at https://***/snap-bof-sigcse23

Towards a formal model of computation for RMAS

Procedia Computer Science 2022年 200卷 865-877页

RMAS is a multi-agent system architecture and associated model of computation that has been recently proposed as promising framework for autonomic computation and as viable implementation means for industrial agents. RMAS is proposed as an effective tool in the realization of the full-fledged concept of cyber-physical systems of systems, in agreement with new visions of the digital future and prominent standardization efforts like the IEC 61499. Currently, there is the need to establish a solid formalism for the model of computation of RMAS in order to harness and fully express its possibilities. In particular, this model should bridge the disciplines of control and systems engineering and computer science, whilst concerning artificial intelligence. This work proposes a first operational step in this direction. A formalism of the RMAS model of computation is established for the first time, and a complete definition of hierarchical nested levels of RMAS units is proposed. This work constitutes the ground for industry-ready technological instances of the RMAS architecture.

The research on paradigms in audio and music programming is an ongoing endeavor. However, although new audio programming paradigms have been created, already established paradigms did prevail and dominate major music production systems. Our research aims at the question, how programming paradigms and music production interacts. We describe the implementation process of an imperative algorithm calculating the greatest common divisor (gcd) in Pure Data and exemplify common problems of transformational processes between an imperative paradigm and a patch-paradigm. Having a closer look at related problems in research on programming paradigms in general, we raise the question of how constraints and boundaries of paradigms play a role in the design process of a program. With the deliberation on selected papers within the context of computer science, we give insight into different views of how the process of programming can be thought and how certain domains of application demand a specific paradigm.

Algorithmic Design (AD) is a novel approach to architectural design based on the creation of form through algorithms. The inherent flexibility of AD encourages the exploration of a wider design space, the automation of design tasks, and design optimization, considerably reducing project costs. Nevertheless, current AD uses representation methods that radically differ from those used in architectural practice. This creates a barrier to the adoption of AD, thus, limiting the potential benefits. We propose to address this problem by coupling AD with complementary representation methods that are adequate for designing complex architectural projects and by supporting their synchronization in a dedicated design tool.

The dream of programming language design is to bring about orders-of-magnitude productivity improvements in software development tasks. Designers can endlessly debate on how this dream can be realized and on how close we are to its realization. Instead, I would like to focus on a question with an answer that can be, surprisingly, clearer: what will be the common principles behind next-paradigm, high-productivity programming languages, and how will they change everyday program development? Based on my decade-plus experience of heavy-duty development in declarative languages, I speculate that certain tenets of high-productivity languages are inevitable. These include, for instance, enormous variations in performance (including automatic transformations that change the asymptotic complexity of algorithms);a radical change in a programmer's workflow, elevating testing from a near-menial task to an act of deep understanding;and a change in the need for formal proofs.

Escaping the Prison of Style 20

Escaping the Prison of Style

We seek support for our notion of authorially open programming practices through a critical reading of the notion of "style" in our dominant programming cultures. We argue that this popular notion of programming style is inescapably infused with values which diverge from those of its supposed analogues in areas such as literary and artistic expression. By examining the discourse around and technical distinctions between programming styles, we reveal their fundamentally different nature in structuring dialogues between the writers of computational artefacts and those who experience them. programming styles are predominantly discussed in inward-facing terms, i.e. with regard only to the experience of programmers with privileged access to the source code. Regardless of their chosen style, programs consist of "imprisoned expressions", built of design elements cut off from access to the program which executes in the world. We construct a miniature integration language, still bounded within the space of existing programming language styles, to solve an open authorship problem, and observe that the increased open ownership of expressions has come at a significant usability cost. We fail to escape the prison, and reflect that our own dialogue remains predominantly inward-facing, due to the lack of proper materials and vocabulary to put communities into correspondence. We look forward to more convivial venues and idioms for expressing computational artefacts, with more equal relationships between the ecologies of construction and ecologies of use.

Scientific workflows have been used as a programming model to automate scientific tasks ranging from short pipelines to complex workflows that span across heterogeneous data and computing resources. While utilization of scientific workflow technologies varies slightly across different scientific disciplines, all informatics and computational science disciplines provide a common set of attributes to facilitate and accelerate workflow-driven research. Scientific workflows provide assembly of complex processing easily in local or distributed environments via rich and expressive programming models. Scientific workflows enable transparent access to diverse resources ranging from local clusters and traditional supercomputers to elastic and heterogeneous Cloud resources. Scientific workflows support incorporation of multiple software tools including domain specific tools for standard processing to custom generalized workflows and middleware tools that can be reused in various contexts. Scientific workflows often collect provenance information on workflow entities, e.g., workflow definitions, their executions and run time parameters, and, in turn, assure a level of reproducibility while enabling referencing and replicating results. While doing all these, scientific workflows often foster an open-source, open-access and standards-driven community development model based on sharing and collaborations. Cyberinfrastructure platforms and gateways commonly employ scientific workflows to bridge the gap between the infrastructure and users needs. While capturing and communicating the scientific process formally, workflows ensure flexibility, synergy between users, provide optimized usage of resources, increase reuse and ensure compliance with system specific data models and community-driven standards. Currently, scientific workflows are used widely in life sciences at different stages of end-to-end 'data lifecycle from generation to analysis and publication of biological data. The

Today's innovation processes are interdisciplinary and require communication between stakeholders from different domains. The compatibility of mental models, which determine how individuals think about technical problems, decides the success of this communication. Previous research indicates that mechanical engineering students prefer procedural over structural approaches. However, structured research into the source of this preference is rare. This paper presents a study (n = 67) that investigates the mental models of mechanical engineering students of technical systems. Results indicate that mental models may depend on the presentation of a problem. A questionnaire yielded a preference for a procedural approach, while questions prompting verbal information instead yield a structural preference.
