So long as teachers fail to distinguish(区别) between teaching and learning, they will continue
to undertake to do for children what only children can do for themselves. Teaching children to read
is not passing reading on to them. It is certainly not endless hours spent in activities about reading.
Douglas insists that "reading cannot be taught directly and schools should stop trying to do the
impossible".
Teaching and learning are two entirely different processes. They differ in kind and function. The
function of teaching is to create the conditions and the climate that will make it possible for children
to plan cleverly the most efficient(有效的) system for teaching themselves to read. Teaching is also
a public activity: it can be seen and observed.
Learning to read involves all that each individual does to understand the world of printed language.
Almost all of it is private, for learning is an occupation of the mind, and that process is not open to
public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching
that will aid the child in the long search for knowledge? Smith has one principle rule for all teaching
instructions. " Make learning to read easy, which means making reading a meaningful, enjoyable
and frequent experience for children."
When the roles of teacher and learner are seen for what they are, and when both teacher and
learner fulfill them properly, then much of the pressure and feeling of failure for both is got rid of.
Learning to readis made easier when teachers create an environment where children are given the
chance to solve the problem of learning to read by learning.
