## Best Practices

- Implement accessibility standards (WCAG)
- Support mobile learning
- Enable offline access
- Provide real-time feedback
- Use adaptive learning algorithms
- Protect student data privacy (FERPA)
- Enable collaborative learning
- Provide detailed analytics
- Support multiple content formats
- Implement plagiarism detection
- Enable parent/guardian access
- Support multilingual content

## Anti-Patterns

❌ Poor mobile experience
❌ No accessibility features
❌ Ignoring data privacy
❌ No analytics or reporting
❌ Inflexible assessment tools
❌ No offline capabilities
❌ Poor user experience
