Poster for CLT classroom

I think that visualizing of  the knowledge helps to retain it in mind much longer than gaining it just by reading. It is necessarily important to gain knowledge by visually as well as reading or writing in order not to forget in a short time. Because of the fact that language learning definitely requires a good memory, in particular for improving vocabulary knowledge, the using of visuals can be counted as an essentials of language teaching. Therefore, it would be a perfect idea to start the lesson with the poster in order to provide learners with an opportunity to decode and encode the knowledge by the means of pictures or any other visuals.
