Although I have heard that it leads to the development of children listening, speaking ability, but it will not be effective in enabling students to acquire knowledge of languages is also cannot be effective in building a child's ability to read and write.

“Heard although is in the lead” can develop the child to listen to, to say ability, but cannot cause the student effective grasping language knowledge actually, also cannot effective trained child's read-write ability.

"I hear leading" are able to develop your child's listening and speaking ability, but you cannot equip students with knowledge, is not effective in fostering children's ability to read and write.
