The difference between approach, method and technique

The terms approach, method, and technique are interrelated words. These concepts have been discussed by various scholars, among of which is Douglas Brown. The discussions were/are mostly intended to make a distinction between the three terms and to show the correlation between them
 

APPROACH

An approach is a set of assumptions about the nature of language (Brown). In lay words, It is generally a theory that attempts to explain how languages are learned. For example, behaviorism is a language learning theory that suggests that learning language occurs through a process of stimulus/response and reinforcement
 

METHOD

A method is a set of techniques or procedures that are used systematically with the aim of reaching efficient learning. A method is often based upon the premises of an approach (es). The audio lingual method is an example of teaching method, it is based on the premises of behaviorism
 

TECHNIQUE

PPP (presentation, practice, production) is one of the famously known and most widely used techniques in language teaching. This Technique is characteristic of audio lingual method. It is therefore one of many techniques of the audio lingual method. If a method is a set of techniques/procedures that are intended to make the process of learning fruitful, a technique is one single technique of a method
