Aims - considering realistic goals for the lesson, not too easy but not too difficult. You may find the following checklist useful:
- What do the students know already?
- What do the students need to know?
- What did you do with the students in the previous class?
- How well do the class work together?
- How motivated are the students?
Variety - an important way of getting and keeping the students engaged and interested.
Flexibility - expect the unexpected! Things don't always go to plan in most lessons. Experienced teachers have the ability to cope when things go wrong. It's useful when planning to build in some extra and alternative tasks and exercises. Also teachers need to be aware of what is happening in the classroom. Students may raise an interesting point and discussions could provide unexpected opportunities for language work and practice. In these cases it can be appropriate to branch away from the plan.
