High School Biology Textbooks "Two Development" Study

To realize our country’s high school curriculum from "subject oriented" to "the historical transformation of people-oriented" a new round of curriculum reform. Each curriculum reform teaching material is an important from the topic. Teaching material is the carrier of curriculum is the carrier of curriculum Idea, goal and content. However, the teaching process is situational, dynamic, generative, as static materials inevitably has some defects and limitations. Therefore, with the more and more important role in the development of teaching materials tow times. However, for many teachers and educators, two times the development of teaching materials is a relatively new concept, namely the lack of psychological cognition, the lack of actual participation willingness. Teachers on the teaching of the tow development consciousness and ability is relatively weak, not aware of the importance of the two development of teaching materials, and the use of creative development did not actively participate in the teaching material.Since the implementation of the new biology curriculum, teaching materials from the traditional "knowledge centered" to "take the student development as the center", and the biology classroom teaching design of new curriculum more attention based on the biological concept.With the transformation of the role and function of textbooks "new materials" concept is to "teach by teaching" replaced with the concept of. Therefore, it has very important signify canceto develop two times of biological materials, which can not only make the basic biology curriculum reform theory in our country can develop, can provide a good theoretical basis for the two development of basic education of our country biology textbooks, which is conducive to the implementation of the biology curriculum. To this, the author determined tow times development of study from the perspective of compulsory high school biology textbooks, try two times the development of how to implement compulsory textbook of biological solutions, aims to provide theoretical and practical guidance for the first biological teachers.The research is divided into four parts, the contents are as follows:The first part is an introduction, describes the reason and significance of the topic; discussed the research method; research status and literature review, including research status and domestic about the teaching material and the development of research on the two development material abroad; introduced the concept of textbooks, two development, high school biology textbooks.The second part introduces the theoretical basis and principle of teaching material two time son research and development, the main theoretical basis including teaching materials development two times and two times the development of senior high school biology textbook for three important basic principles.The survey study status quo and some students focus on the development of the teaching materials of two times third, through questionnaires and interviews, to the learning situation of teachers to teach high school biology textbook version of human use and students.How to implement the two development high school biology textbooks of the fourth part is the research focus of this paper and core On the basis of on the analysis of the investigation result, through specific case try to put forward the methods of secondary development of tow high school biology textbooks.
