Research On Unit Teaching Design Pointing To The Core Literacy Of Mathematic

The general High school Mathematics Curriculum Standard(2017 edition revised in 2020)proposes that the high school mathematics curriculum should be based on the development of students,pay attention to the concept of discipline as the core,make the curriculum content structured,theme as the guide,make the curriculum content situational,and promote the implementation of the subject core accomplishment.On the basis of literature research,taking "ADDIE" as the theoretical model and "The equation of conic curve" as an example,the research on unit teaching design pointing to the core literacy of mathematics discipline is carried out.Questionnaire was prepared,the core influencing factors of mathematics discipline were investigated,the status quo and existing problems were analyzed,the influencing factors of the cultivation of core literacy of mathematics discipline and the teaching elements of "conical curve" unit were analyzed,the teaching design and teaching practice of conical curve unit were completed,and the effect was tested.The results show that the factors influencing the cultivation of core literacy include students,teachers and textbooks.It has obvious advantages in developing students' core literacy of mathematics subject to implement unit teaching oriented to core literacy of mathematics subject.The unit teaching design pointing to the core literacy of mathematics subject can highlight the main line of mathematics thought and method,help to form a good mathematical cognitive structure and promote the cultivation of the core literacy of mathematics subject.For the unit teaching design of mathematics core literacy,the following teaching suggestions are put forward: implement the new concept of curriculum reform,carry out mathematics teaching in senior high school around the cultivation of mathematics core literacy;Based on students' learning status,do a good job in the overall design of unit teaching;Improve teachers' professional quality,formulate teaching objectives,highlight key points and break through difficult points in unit teaching.
