Teaching Prepared by Caroline W. Ndirangu

Expository Approach
This involves the kind of teaching that is characterized by predominance of tea-
cher talk with little or no involvement of students on practical activities. It is a 
teacher-centered approach. The teacher gives facts, explains concepts, and gives 
illustrations. Anything that needs to be taught practically is done through teacher 
demonstrations. Student participation is limited to listening and asking questions 
and writing notes as the lesson progresses.
This approach is not considered very effective in the teaching. However, it is 
alleged that there are some topics in science/mathematics that can only be ap-
proached satisfactorily by exposition because their very nature they are difficult 
to teach practically.
