However, teachers and teachers in training need to be able to use approaches and methods flexibly and creatively based on their own judgment and experience. In the process, they should be encouraged to transform and adapt the methods they use to make them their own. Training in the techniques and procedures of a specific method is probably essential for novice teachers entering teaching, because it provides them with the confidence they will need to face learners and it provides techniques and strategies for presenting lessons. In the early stages, teaching is largely a matter of applying procedures and techniques developed by others. An approach or a predetermined method, with its associated activities, principles, and techniques, may be an essential starting point for an inexperienced teacher, but it should be seen only as that. As the teacher gains experience and knowledge, he or she will begin to develop an individual approach or personal method of teaching, one that draws on an established approach or method but that also uniquely reflects the teacher's individual beliefs, values, principles, and experiences. This may not lead to abandonment of the approach or method the teacher started out using but will lead to a modification of it as the teacher adds, modifies, and adjusts the approach or method to the realities of the classroom.
