b and c, don't you think?

Question

the teacher explains and the children practice what has been explained

my experience leads to me to the conclusion that actual practice is the best learning technique. I vote for c.

sounds good

Can you help me with this question?

An instructional approach that maximizes
children's learning would be a:

A. teacher demonstration of good
toothbrushing techniques.

B. 10-minute talk on the benefits
of good dental care.

C. 5-minute session where children
actually brush their teeth.

D. flannel board story about foods
that are good or bad for your teeth.

Would (D) be the correct answer?

Thank you for your help!
