Textbooks, also known as textbooks, are teaching books that are written according to curriculum standards and systematically reflect the subject content. Textbooks are the concretization of curriculum standards, which are different from ordinary books. They are usually divided into volumes, units or chapters according to the academic year or semester. It is mainly composed of content, text, exercises, experiments, charts, notes and appendices, and the text is the main part of the textbook.
Arrangement of teaching materials.
The arrangement of teaching materials determines the arrangement order of the teaching content of a certain subject in one grade or in several grades. There are generally four ways to arrange teaching materials:
First, linear arrangement. This arrangement is a chain, straight line and non-repetitive arrangement of textbook content. In other words, in the arrangement of teaching materials, what has been said before will not be repeated later.
Second, spiral arrangement. It aims at learners' acceptance, which makes some basic principles of a textbook appear repeatedly, and gradually expands and spirals according to complexity, depth and difficulty.
Third, the branches are parallel. It is to divide the content into several parallel units, adopt corresponding teaching methods for these parallel units, carry out teaching activities one by one, and finally make a summary.
Fourth, the comprehensive type is the synthesis of the above methods.
