Isn’t Business Opportunities the lower level one? The conversations/tapescripts are very advanced, and they don’t concentrate enough on functional language development, which is what business people mainly need. Why should they have to fill in a chart with grammar or gapfill when they need practical English contextualized for the types of situations they’d encounter.
Alwayslol, is it International Express? That’s Cambridge text.
For writing, though, i find the very simple text called Company to Company quite good for classes of 6 or more. They have to write letters to each other. A good teacher would use the chunks/patterns and then design their own role play writing scenarios that would be more in keeping with the kinds of businesses their students are in.
That’s the thing about ESP, particularly business English, since each company is diff, pharma, engineering, banks, etc, it’s very hard to write a standard type book across the spectrum of professions. In Japan lots of companies hire their own in house staff of teachers who design specific materials for them based on such things as hotline conversations (Amex, phone companies, etc), or particular types of negotiations. This is much harder in Taiwan as usually business Eng teachers are hired through buxibans or consultants and then farmed out and meant to use the textbooks that those companies sell the students. This is a flaw in the system, I saw after so many years. There are quite a few people I know in the field of designing corporate presentation and negotiation courses, but they mainly just do it kind of freelance (well some have legally set up companies here specifically to do this) It’s hard work, and there’s lots of schmoozing involved. But one thing to remember, be tough on corporate students, give em a good bollocking, and dress and act as professional as a Sr. manager, and you’ll do fine. Carry a damn briefcase and wear a tie or Armani. That ropes them in, I’ve seen.
