2. Why digital content?
• can make a significant difference in student
learning and understanding, and can enhance
a teacher’s ability to demonstrate concepts
• Can be used as an amplifier. It performs more
efficiently, tedious processes that might be
done by hand.
• by providing novel representations which
make salient some aspect of a concept which
is difficult to make explicit.

26. CONCLUSION
• Teacher developed digital content is a powerful tool
for teaching and learning.
• In order to utilize it to its full potential, careful
consideration must be given to how students’
opportunities and abilities to learn are brought out
in their environment and are related to how its use is
structured within the world of work.
• Teachers must have a deep, integrated knowledge of
the content to be taught, the students who are to
learn it, and the constraints of digital content.
