Macmillan Collocations Dictionary
I can see perhaps a very serious student of written English dipping into it if there is truly a word whose possible collocations they want to find out more about. And for any teacher with an intermediate class, they might take a word and use the collocations as a ten-minute lesson filler, but I'm struggling to see the dictionary's value beyond that.
Why those textbooks were not designed for South east Asia
Conversation classes are popular in Southeast Asia but the staple for this course is “Let’s Talk”. Why? Because it is one of the few conversational books available. By the time you have stripped it down and localised the content, you may just as well have done it all by yourself, which of course you have.
A love-hate relationship
There are a lot of excellent books on the market; most of them are produced by major publishers such as Oxford, Cambridge, Longman and Macmillan. The problem a teacher can encounter during an English lesson in Asia is that these books are not always culturally suitable for the learners.
