The size of the group should be appropriate to the age, social maturity and academic level of the students. It is important to remember that in small group instruction, the teacher is responsible for evaluation of the answers of each student. Therefore, the group size may also depend on the experience of the teacher in evaluating and analyzing student responses. If attention cannot be paid to each student, the group is too large. Therefore, the slowest-processing group should be the smallest group.
Students can see teachers and materials .
The teachers should be aware of the position of their hands, fingers or body parts so that they don't block visual material that students have to see. For example, the teacher's body may block the chalkboard writing for a student or two seated at the end of the row. It may also happen that a teacher's arm or finger partially obscures a printed word or picture in the Teacher Presentation Book. All distracting objects should be removed. The chairs or desks are arranged to allow the teacher easy monitoring of everyone in the group.
