| With the deepening of the basic education reform,the 2017 Curriculum Scheme for the Senior High School and 2017 curriculum standards of all subjects have been promulgated,and “key competence” and “key competence of discipline” become the main theme of the teaching,which requires that the teacher's teaching design should aim at cultivating students' key competence of discipline.The research of many experts and scholars shows that “unit teaching design” is an important channel and main way for teachers to cultivate students' key competence.Therefore,combined with the teaching practice,the study decides to use the unit teaching design to cultivate and develop students' key competence of biology discipline.Firstly,on the basis of the definition of “key competence”,“key competence of biology”,“teaching design”,“unit teaching design” and other concepts related to the research by combining relevant information in this thesis,the author combed and integrated the current research situation of these key concepts at home and abroad,determined the theoretical basis of the research,and summarized the model tools and operation steps of unit teaching design and development based on key competence of biology according to previous experience.Therefore,a complete system of high school biology unit teaching design based on the key competence of biology was constructed.It provided some certain research thoughts and theoretical basis for the practice research of senior high school biology unit teaching design based on key competence.Then,taking the unit content of “Chemical Composition of Cell” as an example,through comparative analysis,optimization and integration of the current five major versions of senior high school biology textbooks in China,the framework of the unit teaching content was reorganized,some specific teaching strategies were put forward,and specific unit teaching design and practical teaching were carried out.The result of practical study shows that:(1)unit teaching design is conducive to the cultivation and development of students' key competence of biology.(2)unit teaching design based on the key competence is conducive to the students' deep learning.(3)unit teaching design based on the key competence is beneficial to the front-line teachers to promote their professional development. |
