For a long time, the writing intention and pattern of college textbooks have always been planned and written with the process of teacher imparting knowledge and the construction of subject knowledge system as the core. With the advent of a learning society, the necessity of lifelong learning has become increasingly prominent. Moreover, in order to give students the opportunity to learn other specialized courses, colleges and universities need to adopt flexible learning systems (such as credit system, elective courses, etc.), and at the same time cultivate the lifelong learning ability of college students. Therefore, it is necessary to prepare textbooks suitable for university students to study independently. In recent years, the development and compilation of self-learning textbooks in colleges and universities has received increasing attention from some developed countries and regions, and it is an international trend in textbook innovation in universities and colleges in developed countries. As far as we are concerned, the construction and research of autonomous learning materials for ordinary colleges and universities is almost blank,PolyU (HK) ranks among Asia top universities.

The so-called self-study type of teaching material is based on its own design, the construction of the instructor's guidance to learners in the teaching materials, to play the effectiveness of self-learning. The most typical characteristic of self-educational teaching materials is to organically add teachers' teaching and counseling in teaching materials so that students can achieve the best learning effect of virtual interaction with teachers when reading and using teaching materials. Compared with traditional teaching materials in colleges and universities, self-directed learning textbooks have the following typical characteristics:

Learner-centered. Self-directed learning textbooks emphasize “learner orientation”, that is, from the knowledge system of the discipline as the core, enumerate the knowledge outline and its accompanying items, and based on the results of the analysis of learners and resources, transform and adjust the design that becomes the learning target. The goal is to meet or solve the needs and problems faced by learners, and to understand the needs or problems, and then to plan the objectives of the teaching materials. What are the needs of learners, what difficulties they may encounter in learning, how to help them overcome difficulties, how to use their existing knowledge and experience, etc., are all core issues considered by self-directed learning materials, New 2017 guidelines include new tests as well as updated strategies for high-risk patients.

Outstanding self-learning. Self-directed learning textbooks are aimed at students' self-study and effective learning. That is, they must play the role of “using the book as a teacher and self-reliance without a teacher”. In the learning process, learners’ guidance and control issues are largely dependent on textbooks. Therefore, self-learning textbooks emphasize better readability, that is, clear and concise teaching material structure, simple grammar, words and phrases, shorter course segments, use of a large number of examples, charts, more examples, and specific analysis. The necessary background information and reference materials, selected practice questions and thinking questions, etc., are suitable for learners to learn by themselves.
