High School Mathematics Unit Teaching Design Based On UBD Mode

How to promote students to implement the core literacy of the subject has become the core issue of discussion and research.It is found that compared with traditional class teaching,unit teaching can effectively improve the quality of classroom teaching and promote the implementation of students' core literacy.From the whole point of view,unit teaching design can be regarded as an effective way to implement the core literacy of the subject.Unit teaching emphasizes that on the basis of considering the psychological cognitive characteristics of students,teachers should promote students to systematically master knowledge and implement core literacy,so as to help students understand knowledge and promote the development of students' key abilities and core literacy.Understanding by Design(UbD)mode takes preset teaching objectives as the starting point and forms teaching Design according to the learning performance required by teaching objectives.UbD mode emphasizes that teaching evaluation and teaching activities in teaching design should be carried out around teaching objectives.This research will carry out the teaching design research of high school mathematics unit based on UbD mode in the third chapter "The Concept and Properties of Function" of compulsory high School Mathematics of Human Education A edition.Firstly,literature analysis was used to sort out the research status of unit teaching and UbD mode,and combined with the model of unit teaching design and the three stages of reverse design,the general operation process of high school mathematics unit teaching design under UbD mode was proposed.Second,through questionnaire and individual interview method,the feasibility from theory and practice two Angle to the relevant unit teaching high school math teacher and UbD mode of reverse design present situation investigation,and analyzes the main existing problems,and the teachers' understanding of unit teaching level is not enough,also failed to fully recognize the unit teaching effectiveness.On the basis of the above theory and investigation,taking the unit of "Concept and Nature of function" as an example,the teaching elements are analyzed in combination with the specific steps of the unit design template.According to the three stages of reverse design,teaching design and teaching practice are carried out to form a demonstration case of unit teaching design based on UbD mode.Finally,the teaching design is summarized and reflected,and the mathematics unit teaching strategy based on UbD model is obtained: the theme of the teaching unit is clear,and the expected teaching objectives are designed;Design evaluation method according to teaching target;Create a real situation,promote students to understand,hope to provide some experience in mathematics teaching design.
