dare say that even after the invention of the sources you have
referred to, memorization still remains the primary tool for
preservation and transmission of the Qur’an since every CD,
hard disk, codex etc needs the stamp of a memorizer to certify
if the Qur’an has been correctly recorded in these mediums.
Moreover, memorization of the Qur’an establishes a living
relationship of a memorizer with the Qur’an if he knows what
he has memorized. This relationship of course cements his
faith and augments his ability to practice Islam.
regard Muslims have for the Qur’an and the importance it
occupies in their lives on the one hand and the
easy-to-memorize text of the Qur’an on the other induces
automatically the yearning in a person to commit it to his
second part of your question, I think that this memorization
process should be adjusted to schooling by spreading it over
the entire 4-6 years of high school and college period. Taking
children out from their mainstream education and sending them
to religious seminaries for this purpose not only at times
badly damages their psyche but is also detrimental for their
education. It is advisable that children should not be taken
out of their schools for this purpose. Moreover, if this
process is begun at the age of 12, the child itself is in a
position by this age to choose for himself if he wants to
memorize the Qur’an or not.
