First of all, (1) this study attempts to identify some of the basic concept related to the textbook in chapter 2, (2) chapter 3 suggests other studies which have been done previously (3) chapter 4 presents the framework in the design of units, (4) chapter 5 analyzes the textbook with the framework suggested above. Finally, in chapter 6, this study sets up some components of the units making topics by focusing on the notion of organization.
