According to an article in the November 2006
edition of T H E Journal entitled, Picture
This! Statistics indicate that kids prefer to
learn in a visual world and like to have
information at their fingertips (Villano). By
providing teachers with the latest technology
resources it enables them to use an
inquiry-based approach to learning an approach
that forces students to find answers
for themselves (Villano).
