I recently used this book by Andrew Finch for the aviation class that I previously talked about, and I've also used it for a more intensive conversation class that met 4 times/week over the course of a semester. I've used other books in the series for kids classes as well.
I think the book is okay, but not great and I'll probably not use it again, if I have a choice about it. I'll review some things I like and some things I don't like:
1. It's Korea-based, which makes for more interesting topics of interest to my students.
2. There are a variety of activities to do.
1. The readings are way too long for a discussion book. You could spend a whole 50 minute class on the reading, and never get into the discussion. You could actually use the readings for a reading comprehension class.
2. A lot of the topics are old-news. Family, school life, etc have all been covered by every basic textbook the students have previously studied.
3. For a discussion class, I like short, concise units. Like 2 pages. This book used about 8 pages/unit. It's almost impossible to cover it one class, but to continue the topic into the next class is kind of weird too. Just awkward.
