There is an important difference between good teaching and effective teaching. Good teaching refers to a process of instruction while effective teaching refers to the outcomes of instruction. Among other things, a good teacher is one who provides a review at the start of a new lesson, states reasonable objectives, maintains an appropriate level of lesson difficulty, engages students in the learning process as well as emphasizing important points during instruction. Good teaching focuses on the processes and procedures that a teacher uses while preparing for and delivering instruction. But effective teaching goes one step beyond the process of teaching. It focuses on whether students actually learn from instruction. An effective teacher is, therefore, one whose students learn what they have been taught.
