This rubric assesses student-created mind maps for an OER project-based learning English course in secondary school. It evaluates them on design and layout, presentation of information, use of pictures/multimedia, links, and teamwork/writing. For each category, it provides descriptors to distinguish excellent, good, fair, and needs improvement performance. The rubric aims to objectively score mind maps on engaging visual design, clear organization, effective use of features, relevant content, and proper grammar.
