• Title: Reusable Learning Objects: An Agile Approach
• Authors: R. Pito Salas
• Abstract summary: 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. The paper proposes applying approaches originating in the software engineering community, such as agile methodology, version control and management. The paper examines CourseGen, an open source software platform designed for creating, sharing, reusing and publishing reusable course content.

• Abstract: 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.

  We conduct a systematic, large-scale analysis of code generation using retrieval-augmented generation. We first curate a comprehensive evaluation benchmark, CodeRAG-Bench, encompassing three categories of code generation tasks. We examine top-performing models on CodeRAG-Bench by providing contexts retrieved from one or multiple sources.

  We present a novel perspective for solving knowledge-intensive tasks by replacing document retrievers with large language model generators. We call our method generate-then-read (GenRead), which first prompts a large language model to generate contextutal documents based on a given question, and then reads the generated documents to produce the final answer.

First, PTG learns a set of source prompts for various source generation tasks and then transfers these prompts as target prompts to perform target generation tasks. In extensive experiments, PTG yields competitive or better results than fine-tuning methods.
