From the limitation stated above, some reasonable suggestions for further studies relating to this matter may be offered as followed. First of all, it is suggested that a study on gender bias in EFL textbook dialogues including illustration images and CDs used in this set of English textbooks should be conducted. In addition, an investigation into the same topic but with some other sets of English textbooks written by some other specialists is necessary so that a comparison could be made among these different sets of English textbooks. Moreover, it is recommended that a study on how gender over-representation in the English textbook dialogues affect Vietnamese teachers and students in language teaching and learning should be undertaken.
