| The flexibility of textbook materials means the elasticity contained in the textbook materials and the possibility that the textbook materials could be changed in the process of teaching and study. The view of textbook materials centered on discipline knowledge may easily guide to strong character of the textbook materials, and the flexibility of textbook materials is not equal to the examples in the textbook materials. On the background of new curriculum reform, the meaning of the flexibility of textbook materials develops. It refers to a kind of adaptability, changing possibility and elasticity of textbook materials by purposeful design so that the teachers and the students could creative their own curriculum in space broader than discipline knowledge range, and finally the connection between the discipline knowledge and the life, the individual experience, etc. could be built.The design of the flexibility of textbook materials is based on the multi-background theories of new curriculum reform. It draws support from the viewpoints of constructivism which advocate the indefinite knowledge, the constructive cognition and the example function of the textbook materials; form the perspective of multi-intelligence theory, there is larger flexible space for the textbook materials, and the flexibility of textbook materials is also displayed on multiple teaching patterns; postmodernism holds that the substance of the textbook materials should be a kind of life, the content should be open and the structure should be loose. These all viewpoints enlighten the design of the flexible textbook materials. Whichever theory the design of the flexible textbook materials is based on, the humanism guides it from the beginning to the end.Directed by the multi-background theories of new curriculum reform, in the process of making flexible textbook materials, the content of the textbook materials should have the ability that could be expanded and chosen, and it should shows a direction to guide the teachers and the students to get into the life situation, to pay more attention to individual experience and to encourage multidisciplinary integration; about the structure of the textbook materials, the editor may use the modules of unit organized according to the same topic, the arrangement of ideas which go forward one by one and the multiple tectonic parts of investigating process to achieve the flexibility; when the textbook materials are presenting the layout of printed sheet, the editor could efficiently employ the meaningful pictures, colorful column, different typefaces and blank space on the page as auxiliary methods to assist. |
