| The idea"content form"that is to explore the inner logic construction system by studying the text content of the textbook was put forward by the author's mentor—Zheng Changlong, Professor in Chemistry Department, Northeast Normal University in 2009. With the teacher's lead and other graduate students'help, after nearly two years'effort, the author has form the initial construction of the textbook content form classification system, and has analyzed the six elective modules textbooks (PEP version). This thesis is the formulation for the above research.The paper includes the following 4 parts:The first chapter, introduction section, elaborates the research's background, current situation, problems and methods briefly; analyzes the meaning of the research.The second chapter, the theoretical part, defines the relevant concepts involved in the thesis and forms the construction of the textbook"content form"classification system preliminarily.The third chapter, the specific analysis section, is the main part of the thesis. This chapter analyzes the results of classification which is based on six elective module textbooks"content form"classification system.The last chapter, the comparative analysis section, is the difficult part of the thesis. This chapter compares six elective module textbooks"content form"and their combinations and analyses the comparative results in terms of the disciplinary system and cognitive structure. |
