What do language teachers think about the concept of a lexical syllabus (Sinclair, Willis, Lewis, ...)? The idea has not really caught on, right? Why not? What's needed to make it work? Or is it fatally flawed in some way?
In 2005 Sayuri asked a similar question about the Cobuild English Course and commented "Did any of your students feel a sense of sensory and cognitive overload? ... I found it quite difficult to use, one because I had never used anything based on a lexical syllabus, corpus linguistics and task based methodology...."
I ask because I'm a lexicographer, now writing a book on lexical analysis. I am not really an EFL teacher, though I have done some TEFL in the past. In the 1980s I was managing ed. of the Cobuild dictionary under John Sinclair. After the first edition of Cobuild was published, I moved to OUP for 10 years. I'm now working on lexical semantics in Prague.
