0 likes14 views
The document presents wodel-edu, a framework developed to automate the generation and evaluation of diagram-based exercises, addressing the need for domain-independent exercise creation. It highlights features like automated grading, large-scale exercise generation, and support for various platforms such as Moodle and mobile apps. Future enhancements include extensions for gamification and additional exercise types across different domains.
