As a result, school children are much lazier when they regularly use computer. Some people think that it is necessary for teacher to restraint using computers in educational spaces and use the traditional teaching materials. It can be argued that depending on computer will produce more negative effect than positive ones. To begin, computer has been made communication by using internet connection, especially abroad, resulting in numerous benefits for commerce and business. Furthermore, computer can compute and process some sophisticated tasks by which people are not able to do in a short time. For example, people can access news, medical advice, online education courses and much more via computer and internet. Currently computers are becoming much more popular with wireless technology and smart mobile phone. It is evident that the improvements of computer have made life far easier and more convenient for large numbers of people and will continue to do so for decades to come. However, the effects of computer have not all been beneficial. For example, children spend a lot of time for computer to play game, chatting with their friends or access to harmful website on the internet instead of study activities at the school. They are lazier to do their homework. Consequently, the exam result is quickly falling down. In addition, some people think that it is necessary for teacher to restrict using computers in educational spaces and use the traditional teaching materials. Thank to computer technology teacher easily can prepare a lecture note for student. Nevertheless, the body of knowledge in this lecture note is normally quite big and students are too difficult to catch up with knowledge when the slide only can be appeared in a short time. Teacher may be use computer for higher education and may restrict to use it for secondary or primary school. In conclusion, developments in computer have brought many benefits, yet I believe developments relating to new technology in the future are likely to produce many negative effects that must be addressed if we are to avoid damaging impacts to individuals and society.Đóng
