What teaching resources teachers can use other than internet and books?

nature... people.... experiments... human interaction (facilitating student input against each other)

The resources teachers can make use of are various. Yet what I find more relevant to my students is the world they are living in and this depends upon their background and where they are living.

I personally can use pupils' photo albums, a facebook comment,  a report on Tv, a song, a cartoon, a famous TV or radiop program, a legend or common story related to their country or traditions . I personally love to tell them about some real difficulties which I can face  and ask them for advice...

Actually, being authentic matters in fostering learning and language acquisition!
