February 2026 Highlights for INNODEMS/CBC-Grade-10-Maths: Key features delivered include STACK Content Management Enhancements, Teaching Materials Resource Template, and a critical labeling bug fix in the content pipeline. STACK Content Management Enhancements added an audit script to generate includes for STACK questions, introduced static placeholders for STACK questions, and provided static versions of new questions to ensure consistent access and richer learning resources. Commits: 3aa118f308a02eb15fece788559f3f2b26e4a2ea; 2151d986bda3bf6f9ab58feb3aec5798bb44175a; 642dd0ad7efb6d1af97ba80f7dd7eccaba48620a. Teaching Materials Resource Template introduces a device-aware resource template to improve structure for lesson plans and guides for online and offline scenarios. Commit: 9b9c35de50175ebc72f522103824589f2ac45581. Labeling Script Bug Fix: Do not label lists prevents adding labels to ordered (ol) and unordered (ul) lists, improving content integrity. Commit: 2f30f81c8fc8936dd7458ae4f68c9c24e39f814d. Overall impact: These changes improve content reliability, accessibility, and learning experience by ensuring consistent, offline-capable resources and reducing manual maintenance. They strengthen governance around STACK content and teach-material workflows, enabling faster iteration and safer content publishing. Technologies/skills demonstrated: Python scripting for automation, content management and static content generation, resource templating with device-aware considerations, and a disciplined approach to versioned changes and release hygiene.

August 2025 summary of deliverables focused on strengthening math content quality, maintainability, and STACK workflow efficiency across two repositories: INNODEMS/Ethiopia-University-Basic-Maths and maths/moodle-qtype_stack. Key efforts include modernization of Analytical Geometry with asset integration, modular restructuring, and STACK exercise integration; and expansion of STACK-driven content across logic, set theory, and polynomials with enhanced mappings, a preface, and automation tooling to support STACK workflows. Critical bug fixes addressed arctan-related complex-number argument calculations, Windows compatibility constraints removed a long-named Cramer’s Rule question, and repository hygiene was improved with documentation consistency updates. A targeted fix to the STACK API feedback tag parsing further increased reliability of renderings. Overall, these changes deliver more reliable, scalable math content, faster authoring and review cycles, and stronger cross-repo collaboration, translating to tangible learning quality and developer productivity improvements.
