In Hong Kong, the new Senior Secondary curriculum was introduced at Secondary 4 level in September 2009. The curriculum documents emphasize that textbooks not only provide the core elements of learning in the subjects but should also be designed to develop students’ critical and creative thinking and other generic skills through the information and activities they provide. In addition, textbooks should provide a ‘one-stop shop’ of teaching materials so as to help teachers plan the scope and sequence of their lessons. As teachers still rely on textbooks as an important source of information to support their teaching, all textbooks for Senior Secondary Education have been rewritten for the new curriculum. In this paper, the author presents a case study which aimed to develop a framework for designing a new set of Senior Secondary Information and Communication Technology (ICT) textbooks for use by Hong Kong students. In the study, the author conducted a documentary analysis of textbooks pertaining to the previous version of the curriculum, and interviewed experienced teachers, both in order to examine the design strategies for the new textbooks. The paper also discusses how supplementary teaching materials can be used to support learning, teaching and assessment.[Copyright © 2011 Common Ground, Yiu Chi Lai, All Rights Reserved.]
