Classroom activities
Four kinds of lesson
Using a coursebook

Jim Scrivener is one of the most important actors to refer when talking about teachers development. In his book Learning Teaching written in 1994, he talks about the importance of considering how to plan different activities (probably with different aims) which as an overall have the same objective.
