Collaborative Research: Assessing and Expanding the Impact of OpenDSA, an Open Source, Interactive eTextbook for Data Structures and Algorithms

OpenDSA是一个国际合作的开源项目，有可能从根本上改变数据结构和算法（DSA）以及形式语言和自动机（弗拉）课程的教学。通过将教科书质量的内容与可视化和丰富的自动评估的交互式练习相结合，OpenDSA帮助学生更好地理解算法的行为及其对数据结构的影响。该项目将以多种方式扩展OpenDSA。非常成功的用于弗拉互动教学的JFLAP软件将在使用HTML5标准的OpenDSA框架内重新部署，从而增加访问。广泛的学院和大学将参与传播OpenDSA和评估其对学生学习的影响，并将探讨OpenDSA在一些创新的教学环境中的使用。OpenDSA基础设施将得到丰富，允许教师根据其特定的课堂需求定制材料，并鼓励这些教师贡献新的内容。将进行一些技术教学实验，例如衡量用幻灯片中的音频解说扩充内容的效果，以及用概念图浏览专题。研究这些材料如何改善一系列课程的教学，为这些课程创建了相关内容。这些努力将对未来积极的电子教科书项目的影响，通过展示成功的方法来整合内容，互动性，并通过集中在学生学习的效果，在一个开源的，创造性的共享环境评估整合内容与可视化和丰富的收集实践练习与自动反馈。此外，该项目还将研究使用电子教科书材料如何影响每日生活津贴和弗拉课程教员不断发展的教学方法，并将与商业在线内容出版商一起试验新的传播开放源内容的模式。

OpenDSA is an open source project with international collaboration that has the potential to fundamentally change instruction in courses on Data Structures and Algorithms (DSA) and Formal Languages and Automata (FLA). By combining textbook-quality content with visualization and a rich collection of automatically assessed interactive exercises, OpenDSA helps students better understand the behavior of algorithms and their effects over time on data structures. This project will scale up OpenDSA in a number of ways. The highly successful JFLAP software for interactive instruction on FLA will be redeployed within the OpenDSA framework using HTML5 standards, thereby increasing access. A wide range of colleges and universities will be involved in disseminating OpenDSA and assessing its impact on student learning, and OpenDSA's use in a number of innovative instructional settings will be explored. The OpenDSA infrastructure will be enriched, allowing instructors to tailor the materials to their specific classroom needs, and encouraging new content contributions from these instructors. A number of technical pedagogical experiments will be conducted, such as measuring the effects of augmenting content with audio narration in slideshows, and navigation through topics with concept maps. A study of how these materials can improve teaching in a range of courses for which relevant content was created. These efforts will have an impact on future active eTextbook projects by demonstrating successful ways to integrate content, interactivity, and assessment in an open-source, creative-commons environment by focusing on the effects on student learning of integrating content with visualizations and a rich collection of practice exercises with automated feedback. In addition, this project will study how using eTextbook materials affects the evolving pedagogical approaches of instructors of DSA and FLA courses and will experiment with new models of dissemination for open-source content in conjunction with commercial online content publishers.
