INTRODUCTION

     Materials can be varied as informative that informs the learner about the target language; instructional that guides the learner while practicing the language; experiential that provides experience to the learner while using the language; eliciting that encourages the learner to use the language; and exploratory that supports the learner to find something new about the language (discover). As all we know that there are differences in learning  for all of the people,      Oxford (2002) explains the ideal materials aim to provide all these ways of acquiring a language for the learners to experience and sometimes select from.
     ‘Materials Design & Development’ is used by language teachers effectively in foreign language learning. The teachers may even help their learners to produce materials to support their learning.
      Nowadays materials development is both used by practitioners and academicians. As a practical activity it involves the production, evaluation and adaptation of materials. As a field it investigates the principles and procedures of the design, writing, implementation, evaluation and analysis of materials. Ideally, these investigations both inform and are informed by the development and use of materials. This is the case in a number of recent publications (e.g. Mukundan 2009; Mishan & Chambers 2010; Harwood 2010; Tomlinson & Masuhara 2010) whose authors are both practising writers of language-learning materials and academics theorising about materials development.
