Positive effects
A large number of experts and educators claim that there are obvious advantages of using a course book. Hutchinson and Torres (1994) argue that during periods of change, a course book can serve as a tool for supporting teachers and as an instrument of modifications and alterations. Most teachers consider course books to be valuable aids that offer useful material and support. Also learners need course books to guide them towards the hard process of learning. A course book reinforces the teacher.s work and offers material for further learning and revision. In brief, a course book provides teachers and learners with a structure of teaching and learning, methodological support and opportunities for revision and preparation
(McGrath 2002). Moreover, it gives teachers a relief as it reduces the heavy load of preparation, saves time and makes teaching and learning easier.
