The Whole-Language Approach is effective in helping children to comprehend and learn to read rapidly. It teaches children to appreciate and comprehend the text and not merely decode the sounds.
It is a book-based programme where each session includes introduction, recall and mastery of the vocabulary found in the books. So there is no homework to be done :)
The low teacher-child ratio of 1:4 is an optimum arrangement allowing the teachers to facilitate learning according to each child's pace in learning with individual coaching. Sessions are conducted in a child-friendly environment where children learn and play.
