teaching materials which may consist of either just the course books, but also of a learning package consisting of several parts”.

as a Second Language ESLEnglish as a Foreign Language EFL class makes the selection process crucial.

Textbook is used both by the teachers and the students to determine the activities in the classroom. By using textbook, the teachers can decide
what and how to teach the materials based on curriculum and syllabus. Allington and Strange give their similar view of the important of
textbook, “….a textbook serves as a single repository of information on a subject, allowing both the teacher and the learner to use a single common
source for acquiring the desired content”.
