When you plan to use an activity in any section of your lesson, make sure that it has a focus. Let’s consider, for example, a listening activity. One of the most common mistakes made by a teacher is to play a recording and then ask the students to say what it is about. There isn’t any focus in such activity. The students may get lost as there could be a lot of information in that recording. When you focus the activity on certain information, for example, “Listen and complete the chart with all the numbers you hear” you are helping your students improve their listening skills in a very measurable way.
