Abstract :
Textbooks are among a wide range of tools called language teaching materials which are important resources for teachers in assisting students to learn every subject including English. In recent years several important issues have arisen throughout the English Language Teaching (ELT) profession on the quality of ELT textbooks in the world such as textbook design and practicality, methodological validity, the role of textbooks in innovation, the authenticity of materials in terms of their representation of language, and the appropriateness of gender representation, subject matter, and cultural components. This study intends to review EFL Iranian textbooks evaluation studies which evaluate, compare, and determine the strengths and weaknesses of Iranian EFL high school textbooks from different perspectives and explain the reasons for changing these textbooks. In the light of the findings, it is realized that there may be an essential need for the prescribed EEL textbooks to be modified by the Iranian syllabus designers and textbook developers. In revising the textbooks, good qualities of the textbooks should be retained and the shortcomings should be eliminated. It is suggested that textbooks authors pay close attention to these shortcomings and redesign the textbooks in line with latest trends in the world.
