What are the Advantages and Disadvantages?

The advantages of whiteboards being used in schools:

Because interactive whiteboards are so like conventional whiteboards, they can help even technophobic teachers to use technology comfortably for presentations from the front of the room.
They help in embedding the use of e-learning because they rapidly demonstrate the potential of alternative modes of delivery.

• They allow learners to absorb information more easily.
  
• They allow learners to participate in group discussions by freeing them from note taking.
  
• They allow learners to work collaboratively around a shared task/work area.
  
• When used for whole class interactive testing of understanding, they can provide learner feedback rapidly.

• Interactive whiteboards are more expensive than conventional whiteboards or projector/screen combinations.
  
• Their surface can become damaged, necessitating expensive replacement.
  
• Front projection boards can be obscured by the user(s).
  
• Fixed height boards are often too high to reach the top or too low for their bottom to be readily visible.
  
• If multiple data entry is allowed then inputs can get jumbled, resulting in onscreen gibberish.
  
• If remote access is allowed then some users may be tempted to send disruptive comments or drawings to the screen.
