The keyboard and mouse happened to be the primary modes of putting information into the computer. As compared to other solutions, these two devices have performed admirably well. However, there is a growing realization that excessive emphasis on keyboard and mouse causes damage to the wrist and ligaments of the arms.
The carpal tunnel syndrome is a very well known problem that programmers and other individuals spending too much time on the computer mouse and keyboard face. If you are going to encourage your child to learn with the help of computers and internet, you should be prepared for these health problems as well.
You may end up in a situation where your child just cannot use the keyboard without pain. Once the problem arises, it will be virtually impossible to rectify the same. The child will have to follow a strict regimen of exercises and limited work schedule on the computer to lead a pain free life. This is too high a price to pay for online learning.
Another important complication that you have to consider is the further reduction in physical activity. If you are going to encourage your child to learn more from the internet, he or she will be spending more time sitting at a single place. One advantage of sending your child to school is there is physical activity, irrespective of whether the child likes it or not.
The physical activity referred here is not just related to the physical education or sports lecture. Rather, the entire process of cycling to school, climbing the stairs, moving from one corridor to another and visiting a different lab everyday is going to lead to physical activity. This may not seem like a big thing but you have to understand that all this will end the moment your child starts studying with the help of computer.
