Title: Eliciting Student Scratch Script Understandings via Scratch Charades
With many school districts nationwide integrating Computer Science (CS) and Computational Thinking (CT) instruction at the K-8 level, it is crucial researchers closely inspect the relationship between program expression and student understandings. In this study, we propose and report on our use of Scratch Charades, a game in which students act out Scratch scripts while others build them. The purpose of Scratch Charades is to familiarize students with scripts and blocks without the cognitive overhead of the complex user interface. However, in this study, we also used it to elicit student understandings about Scratch blocks and scripts to design mnemonics to help students debug their code. We propose two building and/or debugging strategies based on our observations.

  1. We describe a tangible block editor for the educational programming language Scratch that allows blind and visually impaired (BVI) students to learn computer programming concepts alongside their sighted peers in mainstream classrooms. In this late breaking work, we provide a description of the design that incorporates many of the key elements of the Scratch visual code editor that promote engagement and lower hurdles to programming. The environment allows a BVI student to work collaboratively with other BVI and sighted students, being accessible to all. Key elements of the design include: the use of magnets and local shape to ensure onlymore »blocks with valid syntax can be connected, the allowance of nested expressions through expansion of code structures with telescoping tubing, and a channel grid work surface that provides structure to aid students working with the much narrower field of view of haptics, as compared to vision.« less
  2. Given the importance of broadening participation in the field of computing, goals of supporting personal expression and developing a sense of belonging must live alongside the goals of conceptual knowledge and developing disciplinary expertise. Integrating opportunities for students to be creative in how they enact computing ideas plays an important role when designing curricula. We examine how student creativity, as expressed through theme and the use of costumes, backdrops, and narrative in Scratch projects, is affected by using a themed starter project. Starter projects are Scratch projects that include a set of sprites and backdrops aligned to a theme (e.g.more »baseball), but no code. Using within-group and between- group comparisons, we establish a baseline of what students do when they are given a starter project and explore how their projects differ in the absence of a starter project. This work contributes to our understanding of the impacts of structured elements within open-ended learning tasks and how we can design computer science learning experiences for students that promote opportunities for self-expression while engaging them in computing.« less
  3. Block-based programming has been overwhelmingly successful in revitalizing introductory computing education and in facilitating end-user development. However, poor code quality makes block-based programs hard to understand, modify, and reuse, thus hurting the educational and productivity effectiveness of blocks. There is great potential benefit in empowering programmers in this domain to systematically improve the code quality of their projects. Refactoring--improving code quality while preserving its semantics--has been widely adopted in traditional software development. In this work, we introduce refactoring to Scratch. We define four new Scratch refactorings: Extract Custom Block, Extract Parent Sprite, Extract Constant, and Reduce Variable Scope. To automatemore »the application of these refactorings, we enhance the Scratch programming environment with powerful program analysis and transformation routines. To evaluate the utility of these refactorings, we apply them to remove the code smells detected in a representative dataset of 448 Scratch projects. We also conduct a between-subjects user study with 24 participants to assess how our refactoring tools impact programmers. Our results show that refactoring improves the subjects' code quality metrics, while our refactoring tools help motivate programmers to improve code quality.« less
  4. While several introductory computer science curricula exist for children in K-8, there are few options that go beyond sequence, loops, and basic conditionals. The goal of this project is to not only fill this gap with a high-quality curriculum supported by complete instructional materials, but to also do so with an equity-balanced curriculum. That is, a curriculum that values advancing equity equally with student learning outcomes. In this paper, we intro- duce barriers to equity in public school classrooms, pedagogical approaches to culturally-relevant curricula, and how our Scratch Encore curriculum is designed to support equity-balanced learn- ing. Finally, we presentmore »results of our pilot year, including early evidence of students taking advantage of the culturally-relevant design aspects.« less
  5. Visual block-based programming environments (VBBPEs) such as Scratch and Alice are increasingly being used in introductory computer science lessons across elementary school grades. These environments, and the curricula that accompany them, are designed to be developmentally-appropriate and engaging for younger learners but may introduce challenges for future computer science educators. Using the final projects of 4th, 5th, and 6th grade students who completed an introductory curriculum using a VBBPE, this paper focuses on patterns that show success within the context of VBBPEs but could pose potential challenges for teachers of follow-up computer science instruction. This paper focuses on three specificmore »strategies observed in learners' projects: (1) wait blocks being used to manage program execution, (2) the use of event-based programming strategies to produce parallel outcomes, and (3) the coupling of taught concepts to curricular presentation. For each of these outcomes, we present data on how the course materials supported them, what learners achieved while enacting them, and the implications the strategy poses for future educators. We then discuss possible design and pedagogical responses. The contribution of this work is that it identifies early computer science learning strategies, contextualizes them within developmentally-appropriate environments, and discusses their implications with respect to future pedagogy. This paper advances our understanding of the role of VBBPEs in introductory computing and their place within the larger K-12 computer science trajectory.« less
