Modern technology is an advantage because it allows parents to stay in contact with teachers more easily. Parents can now go online and see the child's grades, email the teacher, or even see assignments.
A possible disadvantage is the pitfalls of becoming too involved. When parents have access to all grades and assignments, they run the risk of micromanaging the child. This can prevent the child from learning life management skills and developing independence. Parents have to be able to take advantage of the technology in such a way that they support their children without being “helicopter parents” and staying in the child’s way.
As the president of the National Parent-Teacher Association points out, when parents are involved in the child's life it is not an invasion of privacy.
Parental use of all available resources, including electronic monitoring tools, should not be considered an invasion of privacy; it’s simply modern involvement. (nytimes)
Parents have a responsibility to see what their children are doing online, not just to be involved with their grades and schoolwork but to see how they are interacting with other children and the world. There are many dangers online, and it is a parent’s responsibility to stay on top of them.
