The problem gets worse when the teacher explains to a large number of students because we cannot understand the lessons. The spread of contagious disease among students, as well as rheumatism and backache due to awkward sitting postures. Some students force others to sit on chairs in the back of the classroom or on the ground. Mixed together, older students try to dominate younger ones. Overcrowding obstructs teachers from classifying students according to their ages or conditions such as near-sightedness.
Some students sit on different chairs from the standard school desks.
This could cause envy among students. Some parents are asked by the school management to bring chairs and tables for their children. Overcrowding, particularly in the primary level, makes it difficult for teachers to do their job properly. In the first years of education, pupils need a lot of help to learn to read and write. This demands patience, effort and wisdom from the teacher.
