Bad reasons for using games in an adult class

1. Killing time - A good language learning game has a clear purpose and finishes whenever students could more usefully move onto something else. If you think your teacher is making you play games when these two things are not true, for example by making you play a game again when you got a perfect score the first time, then you could ask the school manager/ head teacher if the teachers could clearly explain the reason for each game before you are asked to play it.
2. Learning just like kids - Although adults can learn a lot from how kids naturally pick up a language, the adult brain is very different from a child's one and a class that made children learn the language quickly is not usually one that would work perfectly for adults without some changes. If your teacher seems to be making the assumption that you should learn just like children, then it might be worth asking him or her to explain their language teaching philosophy to you.
3. The teacher just want to try something new - This is a difficult one to judge as a teacher who is always trying new ideas to make better and more interesting classes is usually a good teacher- but that does not always mean that the new game will make the best possible lesson for you today. If you think your teacher is being too experimental with your class, a good way to approach this is to suggest what things you would be happy to do again with comments like "I really enjoyed..." and "Before the test could we ... again?"
4. It's fun for the teacher - Teachers are human too and want to have fun in their jobs sometimes, but the teacher is only one of the people in the class and if the majority of students agree that a game is useless it might be a good time for you to finish the game off quickly and show that you want to move on by opening your book etc.
5. The teacher thinks smiling faces means happy students - Many teachers are surprised when a student who was smiling, laughing and taking part in games later complains about that game or that there are too many games in class. If you enjoy the games but don't think they are useful, it is worth explaining exactly this to the teacher rather than saying that you "don't like games".
6. The teacher doesn't know what else to do - Many English teachers are trained to use games and if the school tells them to stop using them it can be very difficult to think of other interesting and motivating ways of practicing the language. If you have specific ideas for what you could do in class instead, for example something that you did in another class, suggesting this to the teacher or school manager might help them come up with suitable ideas.
