论文摘要
本文讨论了可重复使用的学习对象（RLOS），并在多大程度上履行了诺言，尤其是可重复使用。在过去的20年中，文献中实际上已经讨论了可重复使用的学习对象，但真正的大规模学习和教材共享仍然相对罕见且具有挑战性。本文认为，部分原因是当今使用的学习对象的粒度不利于真正的再利用。当然，整个PowerPoint幻灯片甲板和Word文档都保留在单个文件和文件夹中。这不是理想的情况。结果，教育工作者，教师，课程设计师不断地重新发明轮子，或者在寻找一个出色的任务，解释，定义的地方，以便将其复制。本文认为，要实现有效的学习对象重复使用，需要以下内容：较小，更细致的（微）学习对象；意味着将它们结合成较大的演示产品；以及现代修订和版本控制。本文提出了源自软件工程社区的方法，例如敏捷的方法论，版本控制和管理，标记语言和敏捷出版，它们共同构成了本文标题的敏捷方法。借助该基金会，该论文研究了Coursegen，这是一个旨在创建，共享，重复使用和发布可重复使用的课程内容的开源软件平台。 Coursegen使用Corexgen特定指令的修改后的Markdown格式，例如$ link for to $ and $ include主题。 Coursegen编译器将CourseGen文件的集合转换为最终格式，例如网站或PowerPoint。在过去的三年中，Coursegen在Brandeis University的多个计算机科学课程中设计，使用和完善。
This paper discusses Reusable Learning Objects (RLOs) and to what extent they have lived up to the promise, particularly of reusability. Reusable Learning Objects have actually been discussed in the literature for the last 20 years and yet true large scale sharing of learning and teaching materials remains relatively rare and challenging. This paper argues that part of the reason is that the granularity of the learning objects that are in use today is not conducive to true reuse. Certainly whole PowerPoint slide decks and word documents are kept in individual files and folders. It is not an ideal situation. As a result, educators, teachers, course designers, are constantly reinventing the wheel, or searching for where that one excellent assignment, explanation, definition was last seen so it can be copied forward. This paper argues that to achieve effective reuse of Learning Objects, the following are required: smaller, more granular (micro) learning objects; means to combine them into larger presentation products; and modern revision and version control. The paper proposes applying approaches originating in the software engineering community, such as agile methodology, version control and management, markup languages, and agile publishing, which together form the Agile Approach of the title of the paper. With that foundation laid, the paper examines CourseGen, an open source software platform designed for creating, sharing, reusing and publishing reusable course content. CourseGen uses a modified markdown format augmented by CourseGen specific directives, such as $link to and $include topic. The CourseGen compiler converts a collection of CourseGen files into the final format such as a web site or a PowerPoint. CourseGen was designed, used and refined over the last three years in several Computer Science Courses at Brandeis University.
