When I teach classes of students I teach them for two hours. I cut that time up into smaller segments, dishing out education or entertainment as needed. But the best thing to do is to combine the two.
I have a system in class, every class, where we do a warm-up activity (warmer/icebreaker), an activity, and a game. This is in addition to the bookwork or any other handouts that my employer will usually want me to use.
My warm-up is always in the form of a game, or at least something that is mildly entertaining and that will elicit a few laughs here and there from the students.
The activity is usually something that is done with a partner or in small groups. Perhaps it will be a running dictation, a dialogue, a story-writing exercise, or simply an old handout that worked well before and that I expect will do so again. The activity will almost always have something to do with the grammar/vocabulary that the book is dealing with, but in a much more entertaining way.
I always save the best for last in my classes, and that is the game. I used to do the same game for each class that week. I thought it was easier, and perhaps in many ways it is, but boy do you get sick of the same thing after 7-15 times. Now each class, depending on what unit or chapter the students are on in their books, I'll have a game tailor-made for that particular class. Many of the games you see on this website are games I still use today with only minor variations, usually for my own sanity's sake.
That's how I do my classes, and get an amalgam of education and entertainment...or edutainment. That makes the students happy, I can see it clearly on their faces most of the time, but it also makes the parents happy. They want their children to work hard, but they also want them to be children, which means having fun. Students in China have so much homework as it is, and many take evening and weekend classes in every subject they study at school. That's their day, everyday. When they come to my class I want them to learn, but I want them to have a rest from their rigorous schedules for two hours as well.
