A Knowledge Graph of Micro-topics and Learning Pathways (KGMLP) improves course development efficiency in two ways:

• Content Reusability: The knowledge graph allows instructors to reuse content across different courses or modules. Since the graph highlights the relationships between concepts, content developed for one course can easily be adapted for another, provided the prerequisite relations are similar.
• Modular Content Creation: Instructors can develop content in smaller, modular chunks that align with individual nodes (concepts) in the graph. These modules can then be connected and arranged according to the graph, making it easier to update or modify specific parts of the course without affecting the entire structure.
