The impact of the use of textbooks as one of instructional materials to classroom learning is significant, and they have been shown to be a significant
tool for teachers in classrooms. Textbooks as an instructional material serves as one of the most important means of access for students to the knowledge and
skills they must master. Textbooks also support teachers in making instructional decisions and selecting effective teaching strategies that lead to student mastery of
the language. Richards and Renandya 2002 summarize several roles and characteristics
of effective language teaching materials: 1 Language is functional and must be contextualized, 2 Language development requires learner engagement in
purposeful use of language, 3 The language used should be realistic and authentic, 4 Classroom materials will usually seek to include an audiovisual
component, 5 Learners need to develop the ability to deal with written as well as spoken genres, 6 Effective teaching materials foster learner autonomy, 7
Materials need to be flexible enough to carter to individual and contextual
differences, and 8 Learning needs to engage learners both affectively and cognitively.
