In today’s tech-enabled classrooms, choosing the right teaching tool can be the difference between passive and engaging learning. While digital boards, smart boards, and projectors are often grouped together, their functions, usability, and cost differ significantly. This guide explores their differences, ranks them for smart classrooms, and outlines their pros and cons.
📊 1. Difference Between Digital Board, Smart Board, and Projector
| Feature | Digital Board | Smart Board | Projector |
|---|---|---|---|
| Definition | A large touchscreen with built-in OS and apps | A whiteboard responsive to touch/stylus via projector | Projects visuals from a computer onto a wall/screen |
| Interactivity | Multi-touch, direct stylus/finger writing | Interactive via touch/pen | Non-interactive unless paired with smart tools |
| Software Integration | Built-in OS (Android/Windows), apps, web access | Needs computer + external software | Depends on connected device (laptop/media player) |
| Display Technology | 4K/HD LCD/LED screen | Projection on a whiteboard | LED/LCD/Laser projection |
| Hardware Required | All-in-one system | Requires projector + computer | Needs external media source |
| Usage Environment | Ideal for modern smart classes and video conferencing | Suited for hybrid classrooms | Budget-friendly or legacy classroom setups |

⚠️ Note: Never use physical erasers or non-approved markers—they can damage the touch surface.
❓ 4. Can a Smart Board Be Used as a Whiteboard?
✅ Yes—with some precautions.
You can write or draw using digital pens or fingers on most models.
🔍 BUT:
➤ Only use dry-erase markers if the board supports it (check manufacturer’s instructions).
