As far as i know, a trend of eclecticism in teaching started to develop in the 1980s and the early 1990s, initiated by Sweet and Palmer. They believed that a good method is an eclectic one which requires the teacher to utilize her/his knowledge of language besides her/his experience in psychology. Based on Palmer's multiple line of approach, an eclectic method adopts every good idea and leaves the door open for future developments.
However, the term post-method is recently being used in language teaching circle to represent a seemingly new idea. It argue that teachers are not to imprison themselves and their students in any method, even in an eclectic one. It enables teachers to construct classroom-oriented theories of practice. In other words, the post-method condition gives the authority to teachers to make decisions and generate innovative techniques specific to their own classroom (Rashtchi, 2002).
Through this, post-method condition tries to search for an alternative to method rather than alternative method.
Eclectic is not a method. By definition it is a mixture of methods and/or approaches, without specifying which methods or approaches. So, two people may both be "eclectic" using entirely different methodological references and approaches.
