The purpose of this study is to examine the two different ways in which textbooks are scrutinized by teachers: evaluation for selection and analysis for implementation. In the evaluation for selection process, those with the responsibility for choosing textbooks need to consider not just the fit between the curriculum and the textbook but also the practical issues of usability by teachers and by students. Once a textbook has been selected, teachers need to analyze the resources in the textbook to create a plan for daily lessons and for the whole course that helps them both implement and supplement what is already given in the most efficient and effective way.
