Classroom teaching and learning is a complex, multilayered, and social experience. Many things happen at the same time, and the students and teacher must interpret and process these events with considerable rapidity. Teaching is not a one-way transmission of information, for students influence the process as much as the teacher. The teacher plays an extremely important role in establishing a meaningful classroom environment for students
but in the final analysis, it is the social and psychological activities and responses of each student that determines what he or she learns.
