Recent theory and practice have included :the introduction of Discovery activities : the lexical approach in which it is argued that words and phrases are far better building blocks for language than grammatical structure : classroom stages being given new names to help us describe teaching and learning in different ways; and the study of the diference between spoken and written language to suggest different activities and content on language courses. Futher reading on all these is given in Appendix B on page 187.
