The tool of the study designed to cover five dimensions: layout and design, the objectives of the textbook, teaching methods and activities, language skills, and evaluation.

Clarity of the textbook objectives was one of teachers' negative comments about the current textbook especially female teachers who disagreed that the objectives were treated effectively in the current course. The content of the textbook is not helpful in applying teaching theories and practices. In addition, the content of the textbook has no helpful tests or procedures to evaluate the achievement of the students effectively.
