Advantages and Disadvantages of Silent Way

The Silent Way is the name of a method of language teaching devised by Caleb Gattegno. Gattegno's name is well known for his revival of interest in the use of coloured wooden sticks called cuisenaire rods and for his series Words in Colour, an approach to the teaching of initial reading in which sounds are coded by specific colours. His materials are copyrighted and marketed through an organization he operates called Educational Solutions Inc., in New York. The Silent Way represents Gattegno's venture into the field of foreign language teaching. It is based on the premise that the teacher should be silent as much as possible in the classroom and the learner should be encouraged to produce as much language as possible. Elements of the Silent Way, particularly the use of colour charts and the coloured cuisenaire rods, grew out of Gattegno's previous experience as an educational designer of reading and mathematics programs. (Cuisenaire rods were first developed by Georges Cuisenaire, a European educator who used them for the teaching of math. Gattegno had observed Cuisenaire and this gave him the idea for their use in language teaching.)
The Silent Way shares a great deal with other learning theories and educational philosophies. Very broadly put, the learning hypotheses underlying Gattegno's work could be stated as follows:
1)  Learning is facilitated if the learner discovers or creates rather than remembers and repeats what is to be learned.
2)     Learning is facilitated by accompanying (mediating) physical objects.
3)    Learning is facilitated by problem solving involving the material to be learned.
Let us consider each of these issues in turn.
