The overall aim of Richards and Rodgers' figure is "to propose a framework for describing / comparing language teaching practices of that time". It revolves around the terms
methods / approach / design / procedure. Anthony Edwards, first, proposed such a framework in 1963.
This was the "approach / method / technique" classification.
Now, during Richards and Rodgers' time (1980s), generally
the term "methodology" was used to describe "how languages are
taught” in the classroom but Richards and Rodgers chose to re-define the term “method”.
They chose to use it as an umbrella term for describing any “language teaching
practice” of their time. So, they would describe any selected “method” (TPR,
Community Language Learning, etc) using the terms “approach”, “design” and “procedure”.
Example:
If Anthony Edwards would describe
the Grammar Translation, he would describe it as under – The approach behind
the GT is the structural approach. Any language is a combination of structures
and rules regarding how these structures are arranged accurately. The best way
to learn these structures is using the learners’ knowledge of the mother tongue
and repetition of structures.
As a result of this approach, the GT began
to be used as a method. Based on GT, techniques like teacher dictating
translations of passages in the target language, students translating passage,
drilling, etc were used in the early foreign language classrooms.
If Richards and Rodgers were to
describe Grammar Translation. First of all, they would call it the “Grammar Translation Method”.
Then, they would describe this method using the three term classification of –
“Approach” - Any language is a combination
of structures and rules regarding how these structures are arranged accurately.
The best way to learn these structures is using the learners’ knowledge of the
mother tongue and repetition of structures.
“Design” – Here, they would describe the
syllabus models used in GTM, the learner roles, the teacher roles and materials
used in class.
“Procedure” – Here, they would describe the
techniques used by the teacher, the types of exercises used in class, and other
resources required in the classroom.
