Two key strategies exist, through which you can help distracted students to focus on their studies.
The first strategy, through which distracted students can be helped to focus on their studies, is the one where focus is on showing them the benefits they stand to gain, if they focus on their studies. You have to try to illustrate these in practical terms: for the young minds often lack the capacity to understand abstract concepts such as success and happiness.
The second strategy through which distracted students can be helped to focus on their studies is the one where focus is on showing them the negative consequences they stand to suffer, is they don’t focus on their studies. You can make them aware of things like the poor employment prospects that stare at them, if they don’t focus on their studies. You can also show them things like the prison statistics which tend to reveal that people who don’t focus on their studies sometimes end up in deprivation, having to go through jail terms and other such things.
What is important is to keep on hammering the message till it seeps in: and this calls for patience, for the young people in question are often folks who are going through lots of psychological turmoil.
