Focus of the study

As a guideline for teachers in transferring knowledge to their students, either in the class or out of the class, textbook provides clear framework. It is formulated based on a syllabus in a curriculum. Thus, materials on textbook have been matched with the learning objectives. It makes teacher easy to keep on track of what they should teach to students. b. Ready-made Texts and Tasks A textbook provides texts and tasks which are ready to be used by teacher to teach students. Content of textbook facilitate teachers to prepare teaching materials. They do not consume a lot of time to arrange it, because they just need to select materials and activities which are appropriate to student’s need. c. Guidance A textbook can be guidance especially for inexperience teachers. Sometimes they confuse to explain materials due to the language. They may not be able to produce accurate language on their own. Thus, textbooks as material provider can help them to solve this problem, because textbook presents explanation about materials. d. Autonomy By having textbook, students can do independent learning. They can learn at home before teacher explains materials. They also can use it for review materials that have been learnt. And then, they also can know what aspect that will be tested. In summarized, textbook can be a resource for self-directed learning or self-access to the students. 3 Moreover, Jack C. Richard also mentioned some functions of textbook, which are: a. Textbook provides structure and a syllabus for a program Textbook not only plays as an instructional material but also it can be a syllabus. Materials on textbook are developed based on syllabus in a curriculum, hence it make possibility for teachers to teach without looking at the syllabus. b. Textbook helps standardize instruction 3 Penny Ur, A Course in language Teaching, Cambridge: Cambridge University Press, 2009, p. 184.
