| It has been more than 20 years since the internet entered China. During the period of over 20 years, the internet in China advances rapidly. Network has already been familiar to common people, and people often exchange information, consult materials and buy and sell commodities through the network. Therefore, internet is changing our life, work and even thinking mode gradually.Most of the current senior high school students grow up with development of internet; they will make friends, learn knowledge and conduct entertainment activities through internet. Therefore, network has a great influence on their physical and mental development. Many educational experts have noticed the huge influence brought about by network to students’ physical and mental development, and made a lot of researches on different aspects by centering on the influence of network on adolescents. However, development of network is constantly changing, and new things emerging under the network environment will bring about new influences to students. In 2009, micro blog was popular in China, so information transfer has become faster and more extensive. Everyone can be the promulgator of information. We Chat emerged in 2011, which has changed people’s communication mode. For students, popularity of microblog and We Chat has also brought about new changes to their study life. They are able to carry out “fragmentized†learning by utilizing characteristics of microblog and We Chat like fast information updating speed and dapper contents. Due to “MOOC†tide sweeping across the globe in 2012, educators start to reflect on new education modes. Many colleges and universities begin to introduce “MOOC†curriculums, and primary and secondary schools in different places also start to carry out the teaching test of “flipped classroomâ€. However, technology is a double-edged sword. When network provides convenience for students’ school life, it will also generate some negative effects on their physical and mental development. Due to the openness of network, students will touch some pornographic and violent contents not suitable for the age groups. As a result, rate of juvenile delinquency continues to rise. Besides, some antu-China forces from Western countries will spread information that shakes people’s political conviction through the network; after getting these contents, students’ political conviction will be shaken. Due to fast information’s spreading, the propagation velocity and scope of network rumors will also become higher and more extensive. These things go against physical and mental development of juveniles.As a part of education, ideological and political education naturally has to face various influences of network environment. Senior high school ideological and political class is the major way of conducting ideological and political education for senior high school students. Faced with the new influence caused by changes of network environment, it is the obligatory responsibility of each senior high school ideological and political teacher to seriously analyze advantages and disadvantages caused by network environment to senior high school ideological and political teaching, to enhance advantages and avoid disadvantages, and to continually improve senior high school ideological and political teaching effect. |
