| Facing the current new requirements of talent training quality,the General High School Mathematics Curriculum Standards(2017 Edition Revised 2020)put forward strict teaching requirements for teachers,aiming to change classroom teaching methods so that students can improve their learning ability through practical activities,research and analysis and personalized activities,and thus gain more and deeper understanding of mathematical knowledge.Based on this background,the researcher took Harbin A Middle School as the research object,analyzed the current situation of mathematics classroom introduction through observation and investigation,explored the problems of mathematics classroom introduction in the school,and proposed targeted optimization strategies in order to provide practical reference and help for mathematics teachers in the school to design classroom introduction.In this study,by combing and summarizing the relevant literature,we understand the current status of research on classroom introduction at home and abroad,and review three aspects: basic research on classroom introduction,research on the current situation and optimization strategies,and research on effectiveness.In order to understand the actual situation of the current mathematics classroom introduction,a questionnaire survey and individual interviews with teachers and students were conducted in Harbin A Middle School as the research object,and classroom observation was conducted in the actual classroom.(3)the content of classroom introduction deviates from the teaching objectives;(4)the lack of teacher-student interaction during classroom introduction;(5)the inappropriate timing of classroom introduction.These problems need to be solved in many ways.Therefore,in the light of the school’s actual situation,optimization strategies are proposed from three perspectives:pre-class preparation,in-class implementation,and post-class enhancement.Before the lesson,we need to pay more attention to the introduction process;clarify the ideas of classroom introduction;and choose suitable introduction materials.When implementing the lesson,they need to use a variety of introduction methods flexibly,highlight the students’ main position,and arrange the introduction time reasonably.For post-lesson improvement strategies,schools should organize teacher training to improve teachers’ professional knowledge;teachers can evaluate each other with colleagues through classroom introduction evaluation measurement forms;and pay attention to listening to students’ ideas,and then adjust their own classroom introduction methods. |
