| 2022 revision of the compulsory education mathematics curriculum standard,five changes have taken place,the five is to strengthen the learning cohesion,including points to reasonable design one to second grade curriculum,pay attention to activity,game,life learning design,lower grade mathematics classroom teaching how to combine the characteristics of nature and subject learning,application of life teaching theory to promote students to effective learning,realize the goal of cultivating mathematics discipline core literacy,the author determines the research topic,and the related research.The paper mainly consists of three parts:The first part,through a large number of literature summarized about "life teaching","primary school mathematics life teaching" related domestic and foreign literature,analyzes the origin of the life teaching theory,the core view,compared with other teaching mode advantage,theoretical basis,from the promotion of students’ growth and promote the development of teachers two aspects to determine the life teaching theory applied to the necessity of junior mathematics classroom teaching.The second part,based on the classroom practice of life-based mathematics classroom teaching in the lower grades of primary school,uses the classroom observation method and case analysis method to explain the basis of life-based mathematics classroom teaching theory in primary school is: students are active in learning,able to construct structures according to experience,able to understand the meaning and carry out deep thinking,able to carry out application transfer,and cultivate the innovation ability.According to the principle of student subject,the principle of student cognitive characteristics,the principle of appropriateness,the principle of education and the principle of practice,the design steps of applying birth-activated teaching theory to primary school mathematics classroom teaching are summarized as follows:(1)integrate content and extract units;(2)Subject literacy guidance and establishment of unit objectives;(3)Student-oriented,unit activities;(4)Pay attention to the process,implement the classroom evaluation,and finally design the basic flow chart of the application of birth-activated teaching theory in primary school mathematics classroom teaching.The third part discusses the main implementation strategies of mathematics classroom teaching based on life-oriented teaching theory:(1)to understand the growth of students,specify teaching objectives,collect life materials,choose teaching methods and grasp the internal relationship of content when preparing lessons;(2)In the teaching process,life-oriented situation should be introduced,life-oriented teaching new courses and life-oriented courses should be concluded;(3)In after-school consolidation,we should assign life-oriented math homework,carry out life-oriented off-campus practice,make reasonable use of home-school co-parenting mechanism,and adopt life-oriented evaluation system.Taking the representative mathematics course "classification" in the lower grades of primary school as an example,we analyze how to apply life-oriented teaching theory in the mathematics class of the lower grades of primary school,and finally reflect on this research. |
