What are the virtues and the weaknesses of the commercially-produced materials as opposed to the localized teacher-made materials?
Dr. Richards responds:
Commercial materials are usually intended for a diverse audience of teachers and learners, so will often not be directly applicable to a local context and may need to be adapted and localized. Teacher-made materials have the advantage of reflecting the specific context and the needs of learners in that context. An advantage of commercial materials is that they are usually prepared by experts and carefully edited and field tested before publication. With teacher-made materials there is no guarantee that the quality will match those of commercial textbooks, since teachers may not have had any training in materials’ preparation.
