live coding has gained its prominence in Computer Science (CS) classrooms as it enhances learning experiences by providing realtime demonstrations of programming and debugging during lectures. However, live coding may also present challenges to the effectiveness and inclusiveness of the classroom environment. This experience report presents the use of live coding in an introductory level CS course to better understand its impact on novice learners and their perceptions of the strategy. We conducted a between-subjects study at a public university in the United States across two course offerings. Specifically, the instructor taught the same course in two consecutive quarters: one with live coding and one without. Through assignment and exam scores, grades, and surveys, we compared data from students who experienced live coding with those who did not. We found that while live coding prompted engagement and interaction, and students believed that it helped them learn better, there was no statistically significant difference in course performance in terms of assignment and exam scores, nor in final grades. Additionally, most students prefer to keep live coding in lectures despite the challenges it presents. We also shared challenges, lessons, and practical instructional strategies learned from this experience, in the hope that they will contribute to developing more engaging and inclusive learning experiences in CS classrooms.

Background: live coding, or the process of instructors writing code in real time in front of students, is an alternative teaching method to showing students static code examples. Variations of live coding tightly coupled with more active learning approaches are common, which can make it difficult to understand the contribution of live coding alone. Purpose: In this study, we aim to disentangle the benefits of live coding from live coding with explicit active learning approaches. We compare live coding with no added active learning components to presenting students with static code examples. Methods: We present a programming topic to over 100 students using either live coding or static code examples. To more closely parallel showing static code examples, our live coding process involves simply writing and discussing code. We compare student performance and engagement between the two session modes. Findings: Our results show no significant difference between the two presentation modes in terms of learning outcomes. This suggests that live coding in its most basic form may not be sufficiently different from showing static code examples to impact student performance. We also found that live coding students were much more likely to type code, but no more likely to display other engagement behaviors. However, of the engagement activities, only different levels of code typing corresponded with different learning outcomes. Contributions: This research highlights the need for more explicit differentiation and comparisons of live coding with and without active learning strategies.

Networked, immersive, shared virtual environments are on the rise under the concept of the metaverse. Behind all the hype, however, it is an excellent opportunity for networked and virtual music performances using live coding. Especially in recent years, the use of metaverse environments for live coding performances has seen an upsurge due to the constraints of the global pandemic. While the performances are mostly integrated as 2D video streams into environments such as Mozilla Hubs, it seems reasonable to integrate browser-based live coding languages into these environments. This paper describes developing and integrating two live coding languages based on the Bytebeat concept into metaverse systems. They enable real-time live coding within a virtual environment, even collaboratively, with immersive capabilities through spatial audio rendering and the use of VR and AR devices. In addition, different art experiences through the visual composition of the environments can be created. We will show the development and benefits of the live coding languages implemented and the artistic possibilities these virtual environments offer.

Music listening has changed greatly with the emergence of music streaming services, such as Spotify or YouTube. However, did it inspire us to make new experimental music? live coding YouTube is a response to the anticipation of novel performance practices using streaming media. A live coder uses any available video from YouTube, a video streaming service, as source material to perform an improvised audiovisual piece. The challenge is to manipulate the emerging media that are streamed from a networked service given the limited functionality of the API provided. The piece finds parallels in early experimental music that manipulates magnetic tape and vinyl records. On the contrary, the audiovisual space that a musician can explore on the fly is practically infinite. The performance system is built entirely on a web browser and publicly available in the following address: https://***/

Teaching Programming by Revealing Thinking Process: Watching Experts' live coding Videos With Reflection Annotations

IEEE TRANSACTIONS ON EDUCATION 2022年第4期65卷 617-627页

Contribution: Programming is a complex cognitive activity that involves both conceptual understanding and procedural skills, which is challenging for novices. To develop both program comprehension and implementation competency, this study proposed a live-coding-based instruction. Experts' live coding with think-aloud was recorded. Students then learn algorithmic planning and coding skills by observing experts' thinking and coding processes from the videos. To deploy this pedagogical strategy, a learning platform was developed to present the videos to students who could also annotate their reflection about the videos in the system to deepen their understanding of syntax and concepts of computer programming. Background: Traditional lecture-based programming instruction focuses more on the explanation of syntax and concepts but lacks revealing the dynamic and nonlinear thinking and coding process. Research Questions: This study is to explore the effects of live-coding-based instruction on students' programming knowledge, including declarative program knowledge (program comprehension) and procedural program knowledge (coding skills), and whether the instruction changes their attitude toward programming learning or not. Methodology: An empirical study was conducted with 33 high-school students who were novice programmers in one semester to explore the effectiveness of the live-coding-based instruction and the use of the learning platform. Findings: The experiment results show that watching flowcharting (r=0.369, p <0.05) or coding processes (r=0.409, p <0.05) of experts improves coding skills. This implies that explicit depiction of algorithmic planning and coding processes are essential for building procedural programming knowledge. In addition, reflection on syntactic content of experts' programming plays an important role in programming (r=0.511,p <0.01). The research findings suggest that programming instruction could focus more on developing students' problem-solvin

INTERNATIONAL JOURNAL OF PERFORMANCE ARTS AND DIGITAL MEDIA 2023年第2期19卷 147-157页

作者： Sicchio, Kate Virginia Commonwealth Univ Dept Kinet Imaging & Dance Choreog Richmond VA 23284 USA

This article aims to explore live coding of choreography as real time scoring of the dance performance it is creating. It will define live coding as a performance practice, and way of creating choreographic scores, as well as consider some forms of esoteric programming languages (esolangs) as forms of multicoding and explanations of text. It will then explore the work Terpsicode, a live coding language created to make choreography in real-time resulting in duets for coder and dancer and discuss the ways in which Terpsicode is used in performance by creating visual scores from dance terminology. Terpsicode is a demonstration not only of live coding choreography but of multicoding, allowing for both text and visuals to notate the dance score in real-time while the dancers are interpreting the score into movement.

Human-machine agencies in live coding for music performance

JOURNAL OF NEW MUSIC RESEARCH 2024年第1-2期53卷 33-46页

作者： Xambo, Anna Roma, Gerard Queen Mary Univ London Ctr Digital Music London England Univ West London Sch Comp & Engn London England

In this article, we explore the notion of human-machine agencies in live coding applied to music performance. We first survey the literature on interactive music systems, new interfaces for musical expression, live coding and human-data interaction to identify common characteristics related to agency, which can be applied to the analysis of live coding practices. Then, we propose a theoretical framework for supporting the design, evaluation, and analysis of data-driven, AI-enhanced live coding systems. The framework, inspired by actor-network theory and human-data interaction, is composed of four dimensions: legibility, modifiability, predictability and cardinality. We reflect on two live coding systems built by the authors, utilising the four dimensions. We hope that the framework will help understand live coding in the datafication era, in which the data becomes a participating agent. Beyond live coding, our analysis can inform other artistic practices that use AI in interactive or real-time settings while keeping the human in the loop.

Inside the Matrix: Immersive live coding for Architectural Design

INTERNATIONAL JOURNAL OF ARCHITECTURAL COMPUTING 2021年第2期19卷 174-189页

Algorithmic Design (AD) uses computer programs to describe architectural models. These models are visual by nature and, thus, greatly benefit from immersive visualization. To allow architects to benefit from the advantages of Virtual Reality (VR) within an AD workflow, we propose a new design approach: live coding in Virtual Reality (LCVR). LCVR means that the architect programs the design while immersed in it, receiving immediate feedback on the changes applied to the program. In this paper, we discuss the benefits and impacts of such an approach, as well as the most pressing implementation issues, namely the projection of the programming environment onto VR, and the input mechanisms to change the program or parts of it. For each, we offer a critical analysis and comparison of the various solutions available in the context of two different programming paradigms: visual and textual.

Version control systems, which have proven essential for software engineering, can also provide value to creative and artistic practices. In this paper, we explore version control in the creative domain of live coding music, a generative performance practice where programmers edit and run code live to generate audiovisual artifacts. To that end, we developed SHARP, a lightweight version control system that live coders can use during performances as well as in preparation or practice sessions. We conducted a user study where live coders used SHARP for several weeks, wrote diary entries reflecting on their sessions, recorded a performance using SHARP, and participated in exit interviews. We found that SHARP enabled participants to engage with musical form on the fly in novel ways. In addition, the study revealed multifaceted perspectives on how and when versioning can be useful in the context of live coding. Our results inform the design of versioning systems for live coding and more generally for performance and generative arts practices.

Background and Context. live coding is a teaching method in which an instructor dynamically writes code in front of students in an effort to impart skills such as incremental development and debugging. By contrast, traditional, static-code examples typically involve an instructor annotating or explaining components of pre-written code. Despite recommendations to use live coding and a wealth of qualitative analyses that identify perceived learning benefits of it, there are a lack of empirical evaluations to confirm those learning benefits, especially with respect to students' programming processes. Objectives. Our work aims to provide a holistic, empirical comparison of a live-coding pedagogy with a static-code one. We evaluated the impact of a live-coding pedagogy on three main areas: 1) students' adherence to effective programming processes, 2) their performance on exams and assignments, and 3) their lecture experiences, such as engagement during lecture and perceptions of code examples. Method. In our treatment-control quasi-experimental setup, one lecture group saw live-coding examples while the other saw only static-code ones. Both lecture groups were taught by the same instructor, were taught the exact same content, and completed the same assignments and exams. We collected compilation-level programming process data, student performance on exam and homework questions, and feedback via a survey and course evaluations. Findings. Our findings showed no statistically significant differences between the live-coding and static-code groups on programming process metrics related to incremental development, debugging, and productivity. Similarly, there was no difference between the groups on course performance on assignments and exams. Finally, student feedback suggests that more students in the live-coding group reported that lectures were too fast and failed to facilitate note-taking, potentially mitigating the perceived benefits of live coding.
