learning how to take actual advantage of the machines‘
educational potential.

With the wide use of computers, equipping students with
computer skills has become an important goal of school
systems. The development of these skills forms part of school
curricula. Appropriate goals are set at each grade level, much
as with knowledge and skills in other subject areas
Interactive whiteboard and the wiimote
Interactive whiteboards allow teachers to record their
instruction and post the material for review by students at
a later time. This can be a very effective instructional
strategy for students who benefit from repetition, who
need to see the material presented again, for students
who are absent from school, for struggling learners, and
for review for examinations.
