to teach or to impress?

Nowadays, as technology keeps on changing rapidly,it really depends on the teachers how they are going to make full use of it in enhancing their teaching and learning to the maximum.Many kinds of resources of learning can be found through the internet or around us.All of these resources can be authentic or non authentic materials.In my opinion ,I think the authenticity of a resource do not play much part in helping students especially young learners to learn.Both type of materials are equally important as these materials help the learners to have better understanding of language.
In my perspective, I think a teacher should not pick up or select materials or resources only to impress or making the learning process seems more interesting.I deeply believe that only materials that are suitable and appropriate with a lesson should be integrated in the classroom.A teacher might feel excited when students like the material or resources used but i think a teacher should be able to bear in mind about what exactly the materials can do in helping the students learn language and what can the materials provide apart from it is fun and enjoyable.
