Design and Implementation of OpenDSA Interoperable Infrastructure
OpenDSA is a system for creating rich eTextbooks that combine quality text with visualizations and interactive, auto-graded exercises. As OpenDSA gains recognition, its use increases each year. This mandates a scalable, reliable, and sustainable infrastructure to accommodate the fast-growing demand …

Evaluating the Integration of Online, Interactive Tutorials into a Data Structures and Algorithms Course
OpenDSA is a collection of open source tutorials for teaching data structures and algorithms. It was created with the goals of visualizing complex, abstract topics; increasing the amount of practice material available to students; and providing immediate feedback and incremental assessment. In this …

Disseminating Learning Tools Interoperability Standards
… a use case of how LTI is implemented in the OpenDSA eTextbook system. As another use case, we have enabled auto-grading of Jupyter Notebook assignments by providing immediate feedback to students and updating scores to the Canvas gradebook. We provide a Jupyter plugin to upload notebook files …

Interactive Multimedia in Digital Courses: Design and Evaluation of Concept Maps Glossary and Narration Support
… We implement these concept maps within the OpenDSA e-textbook system. A concept map associated with the selected term is generated on demand. We evaluate the effectiveness of our design by comparing student use of our concept-map based glossary to the traditional alphabetized list. We have …

An Interactive Tutorial for NP-Completeness
… of visualizations that we developed using the OpenDSA framework for certain NP-Complete problems. Our paradigm is a three step process. We first use an AV to illustrate a particular NP-Complete problem. Then we present an exercise to provide a first-hand experience with attempting to solve a …

Categorizing and Comparing Students' Interactions in eTextbooks
… study examines student engagement profiles in OpenDSA, an interactive eTextbook for data structures and algorithms courses. Using session-level interaction data, we categorize engagement into four distinct engagement states, defined as types of student activities: Reading, Visualization, …

Beyond Curation: A Validation and Classification Infrastructure for an Educational Content Catalog
… bundles. For one of our key contributors, OpenDSA—an e-textbook system—we have adopted latest LTI 1.3 standard. This implementation enables the catalog to disseminate content in both LTI 1.1 and LTI 1.3 standards, ensuring compatibility. One key improvement in LTI 1.3 is its security …

Incorporating LLM-based Interactive Learning Environments in CS Education: Learning Data Structures and Algorithms using the Gurukul platform
… Augmented Generation mechanism that uses OpenDSA as its source of truth, allowing the LLM to fetch and present information accurately and relevantly, thereby trying to overcome the issue of inaccuracies. We present these features to evaluate the user perceptions of LLM-assisted educational …

Interactive Visualization for Novice Learners
Iteration, the repetition of computational steps, is a core concept in programming. Students usually learn about iteration in an entry-level Computer Science class. Virginia Tech's Computational Thinking (CT) course is designed to teach non-CS majors computing skills and new ways of thinking. The …

Detecting Credit-Seeking Behavior on Programmed Instruction Framesets
When students use an online eTextbook with content and interactive graded exercises, they often display aspects of two types of behavior: credit-seeking, and knowledge-seeking. Any given student might behave to some degree in either way in a given assignment. In this work, we look at multiple …
