Remember that moment when you get home from work or back from a night class and your partner’s in a bad mood? How long does it usually take you to work it out? Hours? Minutes? A few seconds?
Most of the people I ask say a few seconds, some even go as far to say that they can tell before they’ve even stepped foot in the room. However long it takes you, students are no different, they’ll make up their mind whether the lesson will be enjoyable or not within the first five minutes. This can mean the difference between an engaged learner and a disruptive one, and once an opinion has been formed it can take a lot for that to be changed.
