# course-module · 教学模块 7-slide teaching module: cover (title + meta), objectives, core concept, worked example, exercise, check-your-understanding (MCQ), summary. Academic but friendly look: warm off-white paper, Playfair Display display type, a green/terracotta accent pair. A persistent **left sidebar** on content slides lists the module's learning objectives and checks them off as you progress — students always know where they are. **Use when:** online course modules, lecture handouts, onboarding curricula, workshop units. **Feel:** a good textbook opened to a chapter — structured, quiet, encouraging.
