Poor student behaviour seems to be an increasingly widespread problem and I think that modern lifestyles are probably responsible for this. In many countries, the birth rate is decreasing so that families are smaller with fewer children. These children are often spoilt, not in terms of love and attention because working parents do not have the time for this, but in more material ways. They are allowed to have whatever they want, regardless of price, and to behave as they please. This means that the children grow up without consideration for others and without any understanding of where their standard of living comes from. When they get to school age they have not learnt any self control or discipline. They have less respect for their teachers and refuse to obey school rules in the way that their parents did. Teachers continually complain about this problem and measures should be taken to combat the situation. But I think the solution to the problem lies with the families...
