F. Definition of Terms
This study provided the definition of some important terms in order to avoid different perceptions to these terms and to clarify the concept of the study.
The terms are defined as follows.

Response, Direct Method, and Communicative Language Teaching. In this study, the Natural Approach which is used as the basis theory of the
designed material refers to an approach which facilitates methods and emphasizes on exposure, or input to teach English vocabulary. They are optimizing emotional
preparedness for learning, a prolonged period of attention to what the language learners hear before they try to produce language, and willingness to use written
and other materials as a source of comprehensible input. This can be done by discussing topics of interest, games, tasks, and the like.
