Advantages:
- Interactive Learning: Touch capabilities enable interactive lessons, allowing students to engage with the content directly on the screen. Teachers can annotate, draw, and manipulate objects on the screen.
- All-in-One Solution: Combines a display, whiteboard, and computer in one, eliminating the need for multiple devices in the classroom.
- Supports Collaboration: Multi-touch capability allows multiple students to interact with the screen simultaneously, encouraging group activities and collaborative learning.
- Built-in Educational Software: Comes with apps and tools that are specifically designed for education, making it easier for teachers to plan and execute interactive lessons.
- Real-Time Feedback: Teachers can instantly annotate and provide real-time feedback on student work during lessons.
Disadvantages:
- Higher Initial Cost: Interactive panels are typically more expensive than non-interactive LFDs.
- Smaller Size Compared to LFDs: While highly functional, interactive panels are typically available in smaller sizes compared to large-format displays.
Applications:
- Interactive Lessons
- Collaborative Group Activities
- Annotating Documents/Presentations
- Virtual Classrooms
- Distance Learning
