Authenticity in current course materials

I think the authenticity of the teaching and learning material affected both the inputs and outputs of a course.
Nowadays, children (even p3) can get access to internet easily without parents' and adults' censorship. They can learn by reading others blogs, searching for Pop stars and sports stars info, and even adding post to others' blogs or Facebook. Yet, in the current text books, they are still learning 'Shopping with family or friends in a supermarket', 'hobbies( only healthy ones: ball games, musical instruments)'. Though we are helping them to build up a healthy life style, yet, the life they are living is not as simple as we think.

I know many teachers face drug problems, bullying (including cyber-bullying) or other problems in their schools. I am lucky that my students are still using interent for playing facebook and MSN, which I can censor them by interacting with them on these communication tools. Yet, I need to investigate on their practices on playing games on facebooks as well as helping them to get used to type in English on MSN.
Parents (for some parents) may be idiots to IT and internet. Some of them may think computers can help them learn better, but never imagine the adverse effects that it brings to their children. As teachers, we have the responsibilty to help children get on the right track when incoporating technology in the current ESL curriculum.

I was the one benefits on the Web 2.0 world. Once I started teaching 10 years ago, I was the new generation in teaching field to make the vast uses of technology. Now, it is not the age for teachers to manipulate the technology, but the age for learners to make good use of the technology to learn among themselves as well as with teachers.
