Textbooks, crucial in educational systems, consist of essential teaching materials and represent the organization of systematic knowledge and the bringing together of curriculum and teaching. Hong Kong, however, needs to carry out more research of textbook and to improve the quality of textbooks. This article discusses the roles of the Education Bureau in textbook editing and selection mechanism and suggests ways to enhance those roles. The authors confirm that the Education Bureau plays crucial roles in the textbook mechanism. We suggest, however, that in addition to its present roles, the Education Bureau should cooperate with other relevant organizations to coordinate textbook affairs, conduct more textbook research, and strive to improve the textbook mechanism.
