Here are a few tips to help parents of children who are not studying enough. Talk to the child honestly. In a calm way, without accusing him, ask him why he does not study. Show him that you understand how hard homework is sometimes and reassure him that you will listen to him when he asks for help, but that you will not continually try to tell him what to do. Go through the subjects he has to study with him and establish a study program that the child can follow. Be patient and don't expect it to change in a few weeks.
On the other hand, if he keeps getting better and brings you a pass instead of a fail, don't tell him you're expecting a mark when he gets your grades next time. Talk to your child's teachers too. Do it in a cooperative spirit and with the idea that teachers will help you improve your child's attitude. Ask them to tell you frankly how the child behaves in school and what his ability to study is. Consider having the child take some educational, emotional, and intelligence tests to find out what to expect in terms of solving the problem.
Let us always remember that children are the future of tomorrow.
Study should be done because it's great to learn about everything.
