Abstract

Block-based programming environments have increased students' interest in computer science (CS). Research suggests that block-based programming environments have positively impacted students' retention, effectiveness, efficiency, engagement, attitudes, and perceptions towards computing. We know that when novice programmers are learning to program in block-based programming environments, they need to understand the components of these environments, how to apply programming concepts, and how to create artifacts. However, few studies have been done to understand the impacts that usability of block-based programming environments may have on students' programming. In this poster, we present results from a two-part study designed to understand the impact that usability of the programming environment has on novice programmers when learning to program in Scratch. Our findings indicate that usability challenges may affect students' ability to navigate and create programs within block-based programming environments.

新手程序员在第一次使用Scratch时遇到的可用性挑战

基于块的编程环境增加了学生对计算机科学(CS)的兴趣。研究表明，基于块的编程环境对学生的保留、有效性、效率、参与度、态度和对计算的看法产生了积极的影响。我们知道，当新手程序员在基于块的编程环境中学习编程时，他们需要了解这些环境的组件，如何应用编程概念，以及如何创建工件。然而，很少有研究了解基于块的编程环境的可用性对学生编程的影响。在这张海报中，我们展示了两部分研究的结果，旨在了解编程环境的可用性对初学者学习Scratch编程时的影响。我们的研究结果表明，可用性挑战可能会影响学生在基于块的编程环境中导航和创建程序的能力。
