Textbooks are the main materials used in the classrooms to teach any field in education. Learners mostly get the necessary information from those materials by following up the themes in them. Thus, what is written in those is fundamental for the learners throughout the learning process. Any information written ought to be authentic and fair for each learner. If the government provides its citizens with social justice, it should cover the field of education, as well. The contents of the textbooks used in the schools must be checked in case there is any topic which reflects some inequality or injustice in the textbooks.
There are many topics such as nature, greetings, cultures, sports, festivals, and climate in the books and those topics need to be told authentically. For example, a course book, called Enterprise 3 by Express Publishing, is used as an additional source in an English class. The course book level is pre-intermediate and it is the 3rd edition. In the 22nd unit of the course book, on page 99, the writing section consists of listening about some inventors and their inventions. The students are asked to fill the blanks in the table and write their own projects about those inventors and their inventions. When the students look at the table, they see that all the inventors are males e.g. Galileo, A. Graham Bell, Thomas Edison, Karl Benz, and the Wright brothers. Why did the course book not contain any female inventor like Marie Curie, inventor of the theory of radioactivity to the table? Students need to know both female and male inventors, not only males. They also need to learn women may become what they want, an inventor or a scientist because those pictures provide the students to perceive the models or the roles of the people in the society. Thus, they should be designed well and the content of the course book should be fair for both female and male learners.
