- Teacher Training: Allocate at least 15 hours of professional development per teacher, focusing on:
- Basic operation and troubleshooting
- Curriculum-specific application techniques
- Data security and student privacy protocols
- Assistive technology features for inclusive education
- Technical Infrastructure: Ensure:
- Minimum 100Mbps wired connection per board
- Dedicated IP addresses for each unit
- UPS backup for critical teaching spaces
- Regular firmware update schedule
- Content Development: Create a shared repository of:
- Interactive lesson templates
- Subject-specific toolsets
- Assessment rubrics
- Student progress tracking sheets
- Parent Communication: Conduct informational sessions demonstrating:
- How the technology enhances learning
- Data protection measures
