a resource for presentation material spoken and written
a source for activities for learner practice and communicative
interaction
a reference source for learners on grammar, vocabulary,
pronunciation, etc
a source of simulation and ideas for classroom language
activities
a syllabus where they reflect learning objectives which have
already been determined
a resource for self-directed learning or self-access work a support for less experienced teachers who have yet to gain

Hence, the writer infers that the textbook is one of the instructional tools used in the classroom as a reference in the learning and teaching process so it is
very useful for both the teachers and the students. Textbook could give the teachers an idea or a framework to teach with interesting materials and allow
them to look forward and back for giving them a chance to prepare what’s
coming and review what they have done. For the students, the textbook could help them in reviewing their improvement in the learning process so they could
know their own progress in learning.
