Piaget’s cognitive theory of learning has significant implications for language teachers: (A) It is important to take account of the learner as an individual actively involved in constructing meaning. Thus teachers should help and encourage learners in this process. (B) It is essential to match the requirements of any task to the cognitive level of the learner. Language tasks set by teachers should be neither too abstract for those who are not yet capable of functioning at this level, nor too simple in that the conceptual level is below the level of the learner’s competence. (C) We can see the application of Piaget’s notions of assimilation and accommodation to learning a new language. In this way our knowledge of how the system of the new language operates gradually develops.
