In the past few days I have begun teacher training provided by NELTA - the Nepal English Language Teacher's Association. We were given a very interesting overview of the history of English language education methods in Nepal - which can be broken down to a focus on grammar-translation, followed by oral-structural-situational in the 1970s and then a communicative approach in the 1990s.
At the same time I've been reading On the Mortality of Language Learning Methods by Wilfried Decoo (from a recent post on Language Log), which wonderfully summarizes the history of language education in the past 200 years or so and explains why language teaching seems beset by quick revolutions in methodology that do not provide substantial increases in learning ability.
Additionally, Decoo examines the relationship between language acquisition linguists, teachers, bureaucrats, and language product publishers.
I personally believe that this short article should be required reading for TEFL teachers, even if it may be controversial. Maybe some of you will disagree with me.
